lint-fix-nodemon

Watch your files and run ESLint + fix + nodemon on save

WHY DO YOU NEED THIS?

1. Avoid a double restart when eslint fixes your files (nodemon would normally detect the initial change and then the fix change)
2. Don't get stuck if linting or starting the server fails - we just keep watching and trying again on each save

Installation

npm install lint-fix-nodemon --save-dev or yarn add lint-fix-nodemon -D

Setup

You can run it with npx lint-fix-nodemon or normally you should just add a script to your package.json file.

I usually name it "dev" ("dev": "lint-fix-nodemon") so you can run npm run dev

Configuration

By default, it will assume nodemon should run the script specified as your "main" in your package.json file. Otherwise you can also pass it in as an argument -- for example: lint-fix-nodemon ./api/start.js

Other configuration in terms of what files to watch and lint will be read from the nodemonConfig entry in your package.json file

It will automatically ignore your node_modules folder and any files/folders that start with "."

Setting ESLint extensions

Normally when running eslint from the cli, you must specify the extensions you wish to run on, or it will automatically just default to .js files only.

To avoid having to set it again, we copy the extension settings from the nodemon config set in package.json file. This may mean you need to add some ignore rules in your eslintrc file, to ignore certain file types that you don't want to lint, but you do want changes to cause a nodemon restart.

An example package.json file

{
  ...
  "scripts": {
    "dev": "lint-fix-nodemon api/start.js",
    ...
  },
  "nodemonConfig": {
    "watch": ["api/"],
    "ignore": ["api/scripts"],
    "ext": "js,json,ts"
  },
  ...
}
