Guide

Steps:

• add breakpoint
• open package.json, scroll on start task
• click Debug in the gutter: it will run the script and link it to the debugger
• perform an action that would enter breakpoint
• check breakpoint is reached in call stack

Alternatively:

• start anywhere with node --inspect-brk bin/www
• attach debugger (how ?)

List (eg., for knex, acquireConnection method in client.js):

• disable search exclusion on library: node_module / knex - Mark Directory as / Cancel exclusion
• add breakpoints : search acquireConnection and add breakpoint
• enable stepping-in libraries: Setting / Build, Execution / Debugger / Stepping / Uncheck "Do not step into library scripts"

You may consider option "Do not step into scripts" and add "internals*" to avoid Node.js code, but it's not working that well for me

Use bundled plugin

Use [EnvFile](https://github.com/Ashald/EnvFile) plugin. In Run.debug configuration, check "Environment variables section" Check "Enable EnvFile". Check "Enable experimental integrations" (mandatory for SpringBoot). Add line, select `.env`file.

Lint rules fall into 2 categories:

• formatting, eg indent (make code easier to read) - does not affect the AST
• code-quality rules, eg no-unused-var (avoid bug introduction) - affect the AST

When come against a rule violation, they can work in 2 mode :

• alert: warn, keep code as-is.
• fix

IntelliJ offer support in both categories:

• read configuration file to implement rule, eg. it keys in the appropriate indent when hitting tab
• read configuration file detect rule violation "after-the-fact", eg. by underlining it or through Code inspection (Problem Window)
• fix rule violation, eg. in Reformat (formatting only)

Setting:

• can be imported from Eslint rules (eg, indent)
• can be imported from .editorconfig
• can be set manually in Code Style specific section
• can be set manually in Code Style, section "Other file type"

Fix

• with Reformat (Ctrl Alt R)
• with "Fix ESLint problems" contextual menu (launch eslint -fix)
• with Prettier

EditorConfig properties:

• indent_style
• indent_size
• tab_width
• end_of_line
• charset
• trim_trailing_whitespace
• insert_final_newline

Scope:

• general (all files)
• specific, on file extension

Below a sample for 2 file types

root = true

[*]
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.js]
spaces_around_brackets = both

[*.hbs]
insert_final_newline = false

Use ESLint to reformat
