Nodemon 启动脚本并运行 eslint

Question

I'm starting a project in Vue.JS and I'm a little new to nodemon.

Here is my package.json file

{
  "name": "server",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "nodemon src/app.js --exec 'npm run eslint'",
    "lint": "eslint **/*.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "eslint": "^4.16.0",
    "nodemon": "^1.14.12"
  }
}

I can get nodemon to run through app.js with "nodemon src/app.js". I've tried a whole bunch of combinations after --exec and haven't had any luck.

Answer 1

The correct way is (in package.json and windows):

"scripts": {
    "start": "node index",
    "start-dev": "nodemon --exec \"npm run lint && node index\"",
  },

Answer 2

This works pretty fine for your use-case.

nodemon src/app.js --exec "npm run lint && node"

or you can write nodemon.json file in your root directory

{
  "watch": ["src"],
  "ignore": ["**/*.test.js", "**/*.spec.js", ".git", "node_modules"],
  "exec": "npm run lint && node src/app.js"
}

Answer 3

I've been using a custom script for a while now which I finally published to npm. Check it out here: https://github.com/theoephraim/lint-fix-nodemon

This helps avoid double restarts when eslint fixes your files as well as not failing on the initial run if eslint has fatal errors.

Hope it helps!

Im using nodemon version 1.19.4. You just missed the "events" key. The right way would be to create a nodemon.json in your root folder like that, then a lint script in your package.json with your lint command:

{
  "watch": [ "src" ],
  "ignore": ["**/*.test.js", "**/*.spec.js", ".git", "node_modules"],
  "events": {
    "restart": "npm run lint"
  }
}

Here you can check about Nodemon Events.

When using events you don't need to manually handle your application state (restart, crash, node execution, etc), just put what you want to happen when nodemon refreshes.
