Netlify Serverless Functions - earmuff-jam/invoicer GitHub Wiki

What Are Netlify Functions?

Netlify Functions are serverless functions—essentially backend code that you can deploy alongside your frontend. They let you write Node.js (or Go) code that runs in response to HTTP requests, without needing a traditional server.

Why Use Them Here?

Since SendGrid needs server-side code (you don't want to expose your API keys in the frontend!), you can use a Netlify Function to securely send emails with SendGrid.
