Prompt:

Tell me about using the Azure Free tier to host a static web app

Response:

Using the Azure Free Tier to host a static web app is a great way to deploy simple websites (like portfolio pages, documentation, or frontend apps) with minimal or no cost. Microsoft Azure offers a Free Tier for their Static Web Apps service that includes generous resources for small projects.

Here’s a breakdown of how it works, what you get, and how to set it up:


πŸ”· What Is Azure Static Web Apps?

Azure Static Web Apps is a service designed to host static sites directly from a source repository like GitHub or Azure DevOps. It automatically builds and deploys your web app when you push code to your repo.

It supports:

  • HTML, CSS, JavaScript
  • Frameworks like React, Angular, Vue, and Svelte
  • Static site generators like Hugo, Jekyll, and Gatsby
  • Optional backend APIs via Azure Functions

πŸ†“ Free Tier Features

The Free Tier includes:

Feature Limit
Custom domains βœ… Yes
SSL (HTTPS) βœ… Included
GitHub/Azure DevOps integration βœ… CI/CD pipeline included
API integration (Azure Functions) βœ… 1M requests/month (shared)
Bandwidth 100 GB/month
Storage Not explicitly capped, but suited for small sites
Authentication & Authorization βœ… Basic auth using social logins
Global distribution via CDN βœ… Yes
Staging environments ❌ Not available in Free Tier

βœ… When Is It a Good Fit?

Use the free tier if:

  • You have a personal site or blog
  • You're building a frontend-only web app or SPA
  • You're experimenting with serverless APIs
  • You want a free, managed alternative to GitHub Pages or Netlify

πŸš€ How To Set It Up

1. Prepare Your Static Site

You can use any frontend framework (e.g. React, Vue, Angular) or plain HTML/CSS/JS. Make sure you have a build step that outputs the static files.

2. Push to GitHub or Azure DevOps

Host your code in a public or private repo.

3. Create the Static Web App in Azure

  1. Go to the Azure portal: https://portal.azure.com
  2. Search for Static Web Apps
  3. Click Create
  4. Choose the Free tier
  5. Link your GitHub repo and specify:
    • Branch to deploy
    • Build preset (React, Vue, etc.)
    • Output folder (e.g., build or dist)

4. Let Azure Build and Deploy

Azure sets up GitHub Actions or Azure DevOps pipelines to automatically build and deploy your site on each push.


🌍 Access Your Site

After deployment, your site is live at a *.azurestaticapps.net subdomain. You can also configure a custom domain with free SSL.


πŸ›‘ Things to Note

  • No staging environments: You need a paid tier for preview environments.
  • Function API quotas: If you're using backend APIs, stay within 1M executions/month.
  • Vendor lock-in: It's tightly coupled with Azure infrastructure, unlike Netlify or Vercel.

βœ… Pros

  • Free hosting with CI/CD
  • Global CDN
  • SSL + custom domains
  • API + frontend integration
  • Authentication available out of the box

❌ Cons

  • Limited staging/dev environments
  • No manual deploys unless via Git push
  • Azure portal and setup can feel complex for beginners

Would you like a walkthrough example with a specific framework (like React or Vue)?

Prompt:

Yes with React

Response:

Great! Here’s a step-by-step walkthrough of deploying a React app to Azure Static Web Apps Free Tier using GitHub as your source control.


πŸš€ Deploying a React App to Azure Static Web Apps (Free Tier)


βœ… Prerequisites


1. Create Your React App

If you haven’t already:

npx create-react-app my-static-app
cd my-static-app
npm run build

This generates a production build in the build/ folder.


2. Push to GitHub

git init
git add .
git commit -m "Initial commit"
gh repo create my-static-app --public --source=. --push

Or manually push to a new GitHub repo.


3. Create Static Web App in Azure

  1. Go to the Azure Portal
  2. Search for Static Web Apps, then click + Create
  3. Fill in the details:
    • Subscription: Your Azure subscription
    • Resource Group: Create new or use existing
    • Name: my-static-app
    • Plan type: Free
    • Region: Choose nearest to you
    • Deployment source: GitHub
    • Repository: Authorize and select your React repo
    • Branch: e.g., main
    • Build Details:
      • Build Presets: React
      • App location: / (or leave blank)
      • API location: leave blank (if not using backend APIs)
      • Output location: build
  4. Click Review + Create, then Create

4. Azure Sets Up GitHub Actions Automatically

  • Azure creates a .github/workflows/azure-static-web-apps.yml file in your repo.
  • This workflow runs on every push to your selected branch.

You can inspect it in GitHub under Actions.


5. View Your Deployed Site

After a few minutes, Azure will:

  • Build your React app via GitHub Actions
  • Deploy it to a globally-distributed CDN
  • Provide a URL like:
https://polite-tree-0a1b23e45.1.azurestaticapps.net

You can also:

  • Add a custom domain
  • Enable HTTPS (automatically)

6. (Optional) Add a Custom Domain

  1. In the Static Web App page, go to Custom domains
  2. Click + Add
  3. Follow instructions to map your domain (DNS CNAME)
  4. Azure will auto-generate an SSL cert

🧩 React Routing Tips

If using React Router, add a fallback route in a file named staticwebapp.config.json in your public folder:

{
  "routes": [
    {
      "route": "/*",
      "serve": "/index.html",
      "statusCode": 200
    }
  ]
}

This ensures client-side routing works correctly.


πŸ›  Updating the App

To update your app:

  • Make changes locally
  • Commit and push to GitHub
  • Azure will auto-build and deploy your updates

πŸ“¦ Optional: Add Serverless API (Free Tier allows it)

You can add a backend with Azure Functions, but this requires some extra setup.

Let me know if you want to add an API or authentication to your React appβ€”happy to walk you through that too.


Would you like a working template repo or example config next?

Prompt:

create-react-app is deprecated.

Response:

You're absolutely right β€” create-react-app (CRA) is now deprecated for most use cases. The React team now recommends using more modern tools like Vite, Next.js, or React with frameworks like Remix.

For static sites, Vite is an excellent choice due to its simplicity, fast dev server, and easy build process.


βœ… Let's Walk Through: Hosting a React + Vite App on Azure Static Web Apps (Free Tier)


βš™οΈ 1. Create a Vite + React App

npm create vite@latest my-static-app --template react
cd my-static-app
npm install

Then:

npm run build

This will output your static site in the dist/ folder.


πŸ“‚ 2. Push to GitHub

git init
git add .
git commit -m "Initial Vite + React commit"
gh repo create my-static-app --public --source=. --push

Or push manually to GitHub.


☁️ 3. Create an Azure Static Web App

Go to https://portal.azure.com, then:

  1. Search for: Static Web Apps β†’ Click Create
  2. Fill out:
    • Subscription: Your Azure subscription
    • Resource Group: Create new or use existing
    • Name: vite-react-app
    • Plan type: Free
    • Region: (Pick closest to your audience)
    • Deployment source: GitHub
    • Repository: Select your Vite repo
    • Branch: main (or whatever you're using)
  3. Build Details:
    • Build Presets: Other
    • App location: /
    • API location: (leave blank if no backend)
    • Output location: dist
  4. Click Review + Create, then Create

πŸ”§ 4. GitHub Actions Auto Setup

Azure will auto-create a workflow in .github/workflows/.

Every push to the selected branch will:

  • Run npm install
  • Build the site
  • Deploy to the Azure CDN

🌐 5. View Your Site

Once deployed, you’ll get a live URL like:

https://icy-sky-0561a3e10.1.azurestaticapps.net

You can also add a custom domain with HTTPS, all in the Azure portal.


πŸ” React Router Support (Optional)

If you're using React Router in your Vite app, add this to your root directory:

staticwebapp.config.json:

{
  "routes": [
    {
      "route": "/*",
      "serve": "/index.html",
      "statusCode": 200
    }
  ]
}

This ensures deep links work properly by serving index.html for all routes.


βœ… Summary

Step Tool
React app setup Vite
Git integration GitHub
Hosting platform Azure Static Web Apps (Free Tier)
CI/CD GitHub Actions
Global CDN + SSL + Custom Domain Included

Want a starter template with the Vite + React setup already configured for Azure? I can generate one or show you how to create staticwebapp.config.json, vite.config.js, and the correct GitHub Actions config.

Prompt:

give me the npm create vite@latest syntax again

Response:

Sure! Here’s the command to create a new React app using Vite:

npm create vite@latest my-app -- --template react
  • my-app is your project folder name (change it as you like)
  • The --template react tells Vite to use the React starter

After running it:

cd my-app
npm install
npm run dev

That will start your React app locally with Vite’s dev server!

Prompt:

So no I need a layout with navigation on the left similar to your own

Response:

Got it! You want a React + Vite app with a left sidebar navigation layoutβ€”kind of like this chat UI with a vertical nav on the left and main content on the right.

Here’s a simple example layout using React and plain CSS (you can customize or swap CSS with Tailwind, Chakra, etc.):


React Left Sidebar Navigation Layout Example

1. Project structure

src/
 β”œβ”€β”€ components/
 β”‚    β”œβ”€β”€ Sidebar.jsx
 β”‚    β”œβ”€β”€ NavItem.jsx
 β”œβ”€β”€ App.jsx
 β”œβ”€β”€ main.jsx
 └── index.css

2. Code snippets


src/components/NavItem.jsx

export default function NavItem({ label, active, onClick }) {
  return (
    <button
      onClick={onClick}
      className={`w-full text-left px-4 py-3 hover:bg-gray-200 dark:hover:bg-gray-700 ${
        active ? "bg-gray-300 dark:bg-gray-600 font-bold" : ""
      }`}
    >
      {label}
    </button>
  );
}

src/components/Sidebar.jsx

import { useState } from "react";
import NavItem from "./NavItem";

const navItems = ["Home", "Chat", "Settings"];

export default function Sidebar({ selected, onSelect }) {
  return (
    <nav className="w-60 bg-gray-100 dark:bg-gray-900 h-screen flex flex-col">
      <div className="p-4 text-xl font-bold border-b border-gray-300 dark:border-gray-700">
        MyApp
      </div>
      <div className="flex-grow mt-4">
        {navItems.map((item) => (
          <NavItem
            key={item}
            label={item}
            active={selected === item}
            onClick={() => onSelect(item)}
          />
        ))}
      </div>
    </nav>
  );
}

src/App.jsx

import { useState } from "react";
import Sidebar from "./components/Sidebar";

export default function App() {
  const [selectedPage, setSelectedPage] = useState("Home");

  return (
    <div className="flex h-screen bg-white dark:bg-gray-800 text-gray-900 dark:text-gray-100">
      <Sidebar selected={selectedPage} onSelect={setSelectedPage} />

      <main className="flex-grow p-6 overflow-auto">
        <h1 className="text-3xl font-bold mb-4">{selectedPage}</h1>

        {selectedPage === "Home" && <p>Welcome to the home page!</p>}
        {selectedPage === "Chat" && <p>Here is the chat page.</p>}
        {selectedPage === "Settings" && <p>Settings page content here.</p>}
      </main>
    </div>
  );
}

src/index.css

/* Simple dark/light mode support, adjust as you want */
body {
  margin: 0;
  font-family: system-ui, sans-serif;
}

button {
  background: none;
  border: none;
  cursor: pointer;
  font-size: 1rem;
}

src/main.jsx (entry point for Vite)

import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
import "./index.css";

ReactDOM.createRoot(document.getElementById("root")).render(<App />);

3. How to run

  1. Save all files
  2. Run:
npm run dev
  1. Open http://localhost:5173 in your browser β€” you’ll see the left sidebar with clickable nav items that update the main content.

Optional improvements:

  • Use Tailwind CSS or another framework for easier styling
  • Add icons to navigation
  • Make sidebar collapsible/responsive
  • Use React Router for URL sync

Want me to generate this as a GitHub repo or add Tailwind to it?

Prompt:

When I run npm run dev, the page displays but no css is applied. When I navigate to index.css, the app page is displayed instead of the css

Response:

Ah β€” this sounds like a common issue with Vite when the index.css file is placed incorrectly or not imported properly. If the browser loads the app instead of your CSS file, it's often due to:

βœ… Root cause:

You're navigating to /index.css in the browser, and Vite's dev server is serving your app (SPA behavior), not a static CSS file.


βœ… Solution Checklist

1. βœ… Make sure you're importing the CSS in your main.jsx like this:

import './index.css';

βœ… This ensures that Vite bundles the CSS into your app β€” don’t try to load it via <link> in index.html.


2. βœ… Don't manually navigate to /index.css in the browser

If you go to http://localhost:5173/index.css, Vite will treat it like a route β€” not a static file β€” and render your app instead. This is expected behavior for SPA routing.


3. βœ… Confirm your folder structure looks like this:

src/
 β”œβ”€β”€ App.jsx
 β”œβ”€β”€ main.jsx
 β”œβ”€β”€ index.css   <-- here

And that main.jsx has:

import './index.css';

4. βœ… (Optional) Use DevTools to confirm the CSS is loaded

In Chrome/Firefox:

  1. Open DevTools (right click β†’ Inspect)
  2. Go to Network β†’ Filter by "CSS"
  3. Refresh β€” you should see index.css loaded

5. βœ… Double check Vite isn’t ignoring your CSS

In rare cases, vite.config.js can be misconfigured β€” but if you haven't changed it, this shouldn't be an issue.


Bonus: Example of a complete main.jsx

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css'; // make sure this is here!

ReactDOM.createRoot(document.getElementById('root')).render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

If that doesn’t resolve it, send me:

  • Your main.jsx
  • Your folder structure
  • Any terminal output from npm run dev

I’ll help you debug it quickly.

Prompt:

It is sort of working. I can change the3 background-color of the buttons and that works but the sidebar is displaying at the top

Response:

Got it β€” sounds like your sidebar is stacking above the content instead of displaying vertically on the left, which usually means the layout is missing a proper flex container.

Let’s fix that step-by-step.


βœ… Goal

You want:

[ Sidebar ] [       Main content area        ]

Not:

[ Sidebar ]
[ Main content ]

βœ… Fix: Wrap Sidebar and Main in a flex container

Here's the correct structure in App.jsx:

import { useState } from "react";
import Sidebar from "./components/Sidebar";

export default function App() {
  const [selectedPage, setSelectedPage] = useState("Home");

  return (
    <div className="flex h-screen">
      {/* Sidebar on the left */}
      <Sidebar selected={selectedPage} onSelect={setSelectedPage} />

      {/* Main content */}
      <main className="flex-grow p-6 overflow-auto bg-white">
        <h1 className="text-3xl font-bold mb-4">{selectedPage}</h1>

        {selectedPage === "Home" && <p>Welcome to the home page!</p>}
        {selectedPage === "Chat" && <p>Here is the chat page.</p>}
        {selectedPage === "Settings" && <p>Settings page content here.</p>}
      </main>
    </div>
  );
}

βœ… Fix Sidebar Layout (if not already)

In Sidebar.jsx, make sure you give the sidebar a fixed width and full vertical height:

export default function Sidebar({ selected, onSelect }) {
  return (
    <nav className="w-60 h-full bg-gray-100 dark:bg-gray-900 flex flex-col">
      <div className="p-4 text-xl font-bold border-b border-gray-300 dark:border-gray-700">
        MyApp
      </div>
      <div className="flex-grow mt-4">
        {["Home", "Chat", "Settings"].map((item) => (
          <button
            key={item}
            onClick={() => onSelect(item)}
            className={`w-full text-left px-4 py-3 hover:bg-gray-200 dark:hover:bg-gray-700 ${
              selected === item ? "bg-gray-300 dark:bg-gray-600 font-bold" : ""
            }`}
          >
            {item}
          </button>
        ))}
      </div>
    </nav>
  );
}

πŸ” Checklist

  • div className="flex" in App.jsx β†’ required to make sidebar and main sit side-by-side
  • Sidebar must have a width (w-60) and h-full
  • The root container must be h-screen to stretch full height

Would you like a responsive version where the sidebar collapses on smaller screens too?

Prompt:

Give me step by step instructions to get this material ui template working in my react app: https://github.com/mui/material-ui/tree/v7.2.0/docs/data/material/getting-started/templates/blog

Response:

Here’s your step‑by‑step guide to integrating the Materialβ€―UI v7.2.0 Blog template into your React (Vite or CRA) project:


1. Clone or download the Blog template

From the [Materialβ€―UI GitHub repository v7.2.0 templates collection], locate the Blog template under docs/data/material/getting-started/templates/blog.

  • Option A: Manually download the folder from GitHub
  • Option B: Clone the repo and copy the blog template directory into your project
    This template is part of the official v7.2.0 docs suite MUI+14MUI+14MUI+14GitHub+1.

2. Install dependencies

In your React project directory, run:

npm install @mui/material @emotion/react @emotion/styled @mui/icons-material

Ensure you have compatible React/React‑DOM versions (v17–v19).
For React 18+, you may need to install a matching react-is version and add an override in package.json MUIMUI:

npm install [email protected]
// package.json
{
  "overrides": {
    "react-is": "^18.x.x"
  }
}

3. Copy in template code

Inside your project (e.g. in src/templates/blog), copy:

  • template components (e.g. layout, blog posts)
  • theme and styling files
  • any demo assets

Then import them into your app entrypoint (like App.jsx):

import Blog from './templates/blog/Blog';
// or follow the template's README

4. Wrap your app with MUI theme + emotion

Ensure you’re using Emotion as the default style engine. In your root file:

import React from 'react';
import ReactDOM from 'react-dom/client';
import { ThemeProvider, CssBaseline } from '@mui/material';
import theme from './templates/blog/theme'; // or theme provided by template
import Blog from './templates/blog/Blog';

import '@fontsource/roboto/300.css';
import '@fontsource/roboto/400.css';
import '@fontsource/roboto/500.css';
import '@fontsource/roboto/700.css';

ReactDOM.createRoot(document.getElementById('root')).render(
  <ThemeProvider theme={theme}>
    <CssBaseline />
    <Blog />
  </ThemeProvider>
);

The template likely already contains a default Material theme and Blog component you importβ€”follow its README to align paths.


5. Add Roboto font & icons

Materialβ€―UI expects the Roboto font and icons. You can load via npm:

npm install @fontsource/roboto @mui/icons-material

Then import the font weights and use icons inside your template or components MUI+1MUI+1.


6. Ensure CSS resets and global styles

Make sure <CssBaseline /> from @mui/material is included (as shown above). This ensures browser normalization and baseline typography.


7. Run and validate

Start your development server:

npm run dev
# or
npm start

Check your app in the browser β€” the Blog template layout should appear with proper styling, responsive design, and default theme controls.

Inspect DevTools Network tab to confirm CSS and fonts load correctly.


8. Troubleshooting tips

  • If style sheets aren’t applied: ensure you've installed @emotion/react and @emotion/styled and wrapped with ThemeProvider and CssBaseline.
  • Watch for deep-import usage; v7 disallows deep imports like @mui/material/styles/createTheme. Use proper imports like:
    import { createTheme } from '@mui/material/styles';
    ``` :contentReference[oaicite:24]{index=24}
  • If using Grid2, update imports per v7 changes (legacy vs new component names) MUI.

βœ… Summary

Step Action
1 Download/clone Blog template folder
2 npm install @mui/material @emotion/react @emotion/styled @mui/icons-material
3 Copy template files into src/ and import Blog component
4 Wrap in <ThemeProvider> + <CssBaseline>
5 Import Roboto fonts and icons
6 Run app and validate styling

Let me know if you'd like help adapting the Blog content (e.g. markdown support, routing) or bundling it into a Vite project!

Prompt:

When I run npm react --version or npm react-dom --version I get 10.9.2

Response:

It looks like you’re running commands that don’t quite check the React version correctly:

  • npm react --version and npm react-dom --version are not valid npm commands for checking versions.

How to check your installed React and ReactDOM versions correctly:

  1. Check versions from your project dependencies

Run this in your project directory:

npm list react react-dom

It will output something like:

[email protected]
β”œβ”€β”€ [email protected]
└── [email protected]

  1. Alternatively, check your package.json

Open your package.json and look for react and react-dom in the dependencies:

"dependencies": {
  "react": "^18.2.0",
  "react-dom": "^18.2.0",
  ...
}

  1. If you want to check globally installed versions

Usually React isn’t installed globally, but if you want to:

npm list -g react react-dom

  1. Why are you seeing 10.9.2?

That version 10.9.2 likely comes from some unrelated npm package, maybe a CLI tool or something else (e.g. react-scripts or another package).


TL;DR β€” To check React version installed in your project, run:

npm list react react-dom

Want me to help you check or upgrade your React version?

Prompt:

19.1.1

Response:

Hmm, seeing 19.1.1 sounds like you might be checking the wrong package or a global tool version instead of React itself.

React versions as of now are in the 18.x.x range β€” React 19 doesn’t exist yet.


Let’s double-check the correct React version in your project:

  1. Run this inside your project folder:
npm list react react-dom
  1. If that’s confusing or too verbose, open your package.json and look for:
"dependencies": {
  "react": "18.x.x",
  "react-dom": "18.x.x",
  ...
}
  1. If you want a quick command that shows just the version numbers, try:
npm list react react-dom --depth=0

Why might you see something like 19.1.1?

  • That could be the version of some other npm package (maybe a global tool, or a different library).
  • It’s not React or ReactDOM.

Bonus: Check your React version programmatically

Create a quick script inside your project, e.g. check-react-version.js:

console.log('React version:', require('react/package.json').version);
console.log('ReactDOM version:', require('react-dom/package.json').version);

Then run:

node check-react-version.js

If you want, share your package.json dependencies here and I can help identify the React version!

Prompt:

Latest version of react is 19 see: https://react.dev/versions

Response:

Ah, thanks for the update! You're rightβ€”React 19 has officially launched and is available. The React.dev site shows React 19 as the latest stable release now.

So when you see version 19.1.1, that’s the current official React version!


To check your project’s React 19 version, do this in your project folder:

npm list react react-dom --depth=0

You should see output like:


If you want to upgrade to React 19 in your project, run:

npm install react@latest react-dom@latest

Or specify the version explicitly:


If you want, I can also help you upgrade your Material UI setup or other dependencies to ensure React 19 compatibility!

Prompt:

npm list react react-dom --depth=0

Response:

Running this command:

npm list react react-dom --depth=0

will output the versions of React and ReactDOM installed in your project at the top level.

For example, you might see something like:

[email protected]
β”œβ”€β”€ [email protected]
└── [email protected]

This confirms which versions of React and ReactDOM your project is currently using.

If you want, share the output you get, and I can help you with the next steps!

Prompt:

When you say "Ensure you’re using Emotion as the default style engine. In your root file:" by "root file", do you mean main.jsx

Response:

Yes, exactly! By "root file", I mean your app’s main entry point where React renders the app β€” in a Vite project that’s typically main.jsx (or main.tsx if using TypeScript).

That’s where you want to:

  • Import your CSS baseline (CssBaseline)
  • Wrap your app in MUI’s <ThemeProvider>
  • Import any global fonts (like Roboto)
  • Render your main <App /> or in this case, the Blog template component

So in your main.jsx, you’d have something like this:

import React from 'react';
import ReactDOM from 'react-dom/client';
import { ThemeProvider, CssBaseline } from '@mui/material';
import theme from './path/to/theme'; // your MUI theme
import Blog from './path/to/Blog';   // the Blog template component

import '@fontsource/roboto/300.css';
import '@fontsource/roboto/400.css';
import '@fontsource/roboto/500.css';
import '@fontsource/roboto/700.css';

);

If you want, I can help you create or verify your main.jsx for the template!

Prompt:

When I add the line "import Blog from "./templates/blog/Blog";" to main.jsx and build, the error "Expression expected" is returned

Response:

Thanks β€” the "Expression expected" error usually comes from a syntax issue in your main.jsx, often caused by:

  • A missing or extra bracket, quote, or semicolon
  • A misnamed file or invalid import path
  • TypeScript-specific syntax in a .jsx file
  • Trying to import a non-existent or incompatible module

Let’s troubleshoot this step-by-step:


βœ… 1. Check the import path

Make sure the file Blog.jsx exists at:

src/templates/blog/Blog.jsx

And that you’re importing it like this in main.jsx:

import Blog from "./templates/blog/Blog";

File paths are case-sensitive and must point to the .jsx file (extension is optional but must be correct).


βœ… 2. Check for typos or syntax issues in main.jsx

Here’s a minimal correct example for main.jsx (Vite, React 18+):

import React from 'react';
import ReactDOM from 'react-dom/client';
import { ThemeProvider, CssBaseline } from '@mui/material';
import theme from './templates/blog/theme'; // optional if included
import Blog from './templates/blog/Blog';    // <-- this import

ReactDOM.createRoot(document.getElementById('root')).render(
  <React.StrictMode>
    <ThemeProvider theme={theme}>
      <CssBaseline />
      <Blog />
    </ThemeProvider>
  </React.StrictMode>
);

Make sure:

  • All parentheses and brackets are matched
  • No dangling commas or invalid JSX outside a function

βœ… 3. Check the Blog.jsx file itself

If Blog.jsx has a syntax error or uses something unsupported (e.g. TypeScript-only syntax in a .jsx file), it will break the build.

The file should look something like:

import React from 'react';

export default function Blog() {
  return (
    <div>
      <h1>Blog Template</h1>
      {/* ...more JSX */}
    </div>
  );
}

If it's a .tsx file, either rename it to .jsx and remove TS syntax, or configure your project to support TypeScript.


βœ… 4. Try isolating the error

Temporarily comment out the line:

// import Blog from './templates/blog/Blog';

And replace it with a placeholder:

const Blog = () => <h1>Hello world</h1>;

If that works, the issue is inside the Blog.jsx file or path.


βœ… 5. Let me know the full error message

If the problem persists, share:

  • Your main.jsx contents
  • The file path and name of the blog component
  • The full text of the error (especially if from the terminal or browser console)

I'll help you fix it quickly from there.

Prompt:

There is no Blog.jsx, only Blog.js and Blog.tsx

Response:

Perfect β€” that explains the error! You're importing a file that doesn’t exist under the name Blog.jsx, which causes the "Expression expected" or sometimes a cryptic syntax error during build.


βœ… Fix

You have two valid options depending on the file you want to use:

βœ… Option 1: Import Blog.js

If you want to use the JavaScript version, update your main.jsx import to:

import Blog from './templates/blog/Blog.js';

Even though you can often omit extensions, Vite or your editor might get confused between .js and .tsx, so it's safer to include the extension explicitly when ambiguity exists.


βœ… Option 2: Use Blog.tsx (TypeScript)

If your project is TypeScript-based, you can use the .tsx file like this:

import Blog from './templates/blog/Blog.tsx';

But make sure your project is set up for TypeScript (i.e., your files are .ts/.tsx, and you have tsconfig.json). If your project is still using .jsx/.js, this may cause type errors or build failures.


Bonus Tip: Rename if needed

If you want to keep your import clean and stick with .jsx, you can rename Blog.js β†’ Blog.jsx:

mv src/templates/blog/Blog.js src/templates/blog/Blog.jsx

Then:

import Blog from './templates/blog/Blog';

Let me know which option you prefer or if you'd like to convert the blog component from TypeScript to plain JS/JSX!

Prompt:

Still getting the same error src/templates/blog/Blog.js (12:4): Expression expected. This is file Blog.js: import * as React from 'react'; import CssBaseline from '@mui/material/CssBaseline'; import Container from '@mui/material/Container'; import AppTheme from '../shared-theme/AppTheme'; import AppAppBar from './components/AppAppBar'; import MainContent from './components/MainContent'; import Latest from './components/Latest'; import Footer from './components/Footer';

export default function Blog(props) { return ( <AppTheme {...props}> <Container maxWidth="lg" component="main" sx={{ display: 'flex', flexDirection: 'column', my: 16, gap: 4 }} >

); }

Response:

Thanks for sharing the Blog.js code β€” it looks valid, so the error "Expression expected" at line 12 strongly suggests one of the imported files (likely AppTheme or one of the component imports) is invalid or TypeScript (.tsx) in a plain JS/JSX environment.


βœ… Let's isolate the problem step-by-step:

πŸ” 1. Line 12 is the <AppTheme {...props}> JSX

This line is fine if AppTheme is a valid component. If it's not exporting correctly, or is using unsupported syntax (e.g. TypeScript-only), it could break your JSX parser.


βœ… 2. Check if AppTheme is a TypeScript file

Look at this import in Blog.js:

import AppTheme from '../shared-theme/AppTheme';

Now check:

  • Is AppTheme.tsx?
  • Does it contain TypeScript-only syntax like : Props, React.FC, interfaces, etc.?

If yes, and your project is not set up for TypeScript, you'll get errors like "Expression expected" from Vite/Babel.


βœ… Fix Options

Option A: Convert AppTheme.tsx to JS

If you're not using TypeScript, and want to keep it simple:

  1. Rename the file to AppTheme.jsx
  2. Remove TypeScript-specific syntax:
    • Replace function AppTheme({ children }: { children: React.ReactNode }) with function AppTheme({ children })
    • Remove types, interfaces, React.FC, etc.

Option B: Enable TypeScript support

If you'd prefer to keep the file as .tsx:

  1. Rename your project files to .tsx and install TypeScript:
npm install --save-dev typescript @types/react @types/react-dom
  1. Run:
npx tsc --init
  1. Rename your files:
    • main.jsx β†’ main.tsx
    • App.jsx (if used) β†’ App.tsx
  2. Update imports as needed and ensure type compatibility.

Option C: Temporarily replace <AppTheme>

Comment out AppTheme in Blog.js to see if the error goes away:

export default function Blog(props) {
  return (
    <>
      <CssBaseline enableColorScheme />
      <AppAppBar />
      <Container
        maxWidth="lg"
        component="main"
        sx={{ display: 'flex', flexDirection: 'column', my: 16, gap: 4 }}
      >
        <MainContent />
        <Latest />
      </Container>
      <Footer />
    </>
  );
}

If this works, the issue is definitely in AppTheme.


βœ… Next Step

Can you check the contents of AppTheme and confirm:

  • Is it a .tsx file?
  • Does it use TypeScript-specific syntax?
  • Do you want to remove TypeScript or add support for it?

I can help you convert it or add TypeScript cleanly.

Prompt:

If I start again with a Vite/React app which uses Typescript will these problems go away

Response:

Yes β€” starting with a Vite + React + TypeScript app is the cleanest and most compatible way to use the Material UI Blog template without constantly fighting syntax errors, especially since:

  • The Material UI templates (like Blog) are written in TypeScript
  • Many components and themes in the template use TypeScript-only syntax
  • Vite supports TypeScript out of the box β€” no setup hassle

βœ… What You’ll Gain by Starting Fresh with Vite + React + TypeScript

  • βœ… No more syntax errors like β€œExpression expected” due to mismatched file types
  • βœ… Seamless imports from .tsx files like AppTheme.tsx, Blog.tsx, etc.
  • βœ… Full type checking and IDE support for Material UI components
  • βœ… Ready to use other MUI templates, components, and TypeScript code without rewriting

πŸ›  How to Create a Vite + React + TypeScript App

npm create vite@latest my-blog-app -- --template react-ts
cd my-blog-app
npm install
npm run dev

🧩 Then:

  1. Copy the Blog template code into your src/templates/blog folder.
  2. Use this in main.tsx:
import React from 'react';
import ReactDOM from 'react-dom/client';
import { ThemeProvider, CssBaseline } from '@mui/material';
import Blog from './templates/blog/Blog';
import theme from './templates/blog/theme'; // if it exists

import '@fontsource/roboto/300.css';
import '@fontsource/roboto/400.css';
import '@fontsource/roboto/500.css';
import '@fontsource/roboto/700.css';

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <ThemeProvider theme={theme}>
      <CssBaseline />
      <Blog />
    </ThemeProvider>
  </React.StrictMode>
);

πŸ“¦ Install dependencies:

npm install @mui/material @emotion/react @emotion/styled @mui/icons-material
npm install @fontsource/roboto

βœ… Summary

Option Clean, Fast, Reliable?
Start with Vite + React + JS ❌ Needs rewriting TS code
Start with Vite + React + TS βœ… Fully compatible, no workarounds

You’ll save a lot of time and frustration by just going with the TypeScript setup from the start when using MUI templates.
