eslint-config-loopback

LoopBack's ESLint shareable configs.

Usage

Add eslint and eslint-config-loopback to devDependencies:

npm install -D eslint eslint-config-loopback

In your project root, create/modify .eslintrc:

{
  "extends": "loopback"
}

Then in package.json, set your run script:

...
"scripts": {
  "lint": "eslint ."
},
...

That's it. Try it out by running:

npm run lint

It is recommended to set a posttest run script to auto lint after running tests:

...
"scripts": {
  "lint": "eslint .",
  "test": "mocha",
  "posttest": "npm run lint"
},
...

Overriding rules

To override a particular rule, use the rules key:

{
  "extends": "loopback",
  "rules": {
    "comma-dangle": "off"
  }
}

While adopting ESLint in existing projects, there may be too many errors to fix at once. In such cases, it may be desirable to modify the <code>rule setting</code> of individual rules:

• "off" - Turn the rule off
• "warn" - Turn the rule on as a warning (doesn't affect exit code)
• "error" - Turn the rule on as an error (exit code is 1 when triggered)
