le0nik

Our default export contains all of our ESLint rules for ES6+.

le0nik/node

  2. add "extends": ["le0nik/node"] to your .eslintrc.* config.

le0nik/react

Lints React.js/JSX code.

It includes React/JSX rules only.

  • eslint
  • eslint-plugin-react

You can extend/override the rules for this config. You can find the list of rules here.

Installation:

  1. npm install --save-dev eslint-config-le0nik eslint-plugin-react eslint
  2. add "extends": ["le0nik/react"] to your .eslintrc.* config.

le0nik/lodash

Lints lodash v4 code.

It includes lodash rules only.

It requires:

  • eslint
  • eslint-plugin-lodash

It only supports the default import of lodash, e.g.

var _ = require('lodash') or import _ from 'lodash'

It does not support the usage of:

  • lodash/fp
  • import of separate methods, like
    • var map = require('lodash/map') or
    • var map = require('lodash').map
  • usage of a name, other than _ as your lodash identifier (can be changed, read below)

In your .eslintrc.* config you can change the lodash identifier, that this config is going to look for, like this:

{
  "extends": ["le0nik/lodash"],
  "settings": {
    "lodash": {
      "pragma": "_" // default
    }
  }
}

You can extend/override the rules for this config. You can find the list of rules here.

Installation:

  1. npm install --save-dev eslint-config-le0nik eslint-plugin-lodash eslint
  2. add "extends": ["le0nik/lodash"] to your .eslintrc.* config.

le0nik/jsdoc

Enables requirement for valid JSDoc comments.

It includes JSDoc rules only.

It requires:

  • eslint

You can extend/override the rules for this config. You can find the list of rules here.

Installation:

  1. npm install --save-dev eslint-config-le0nik eslint
  2. add "extends": ["le0nik/jsdoc"] to your .eslintrc.* config.

You should combine these configurations(order does matter) to get the desired rulesets. For example:

ES6+, node and react(with jsx):

{
  "extends": ["le0nik", "le0nik/node" "le0nik/react"]
}

ES6+, JSDoc and lodash:

{
  "extends": ["le0nik", "le0nik/jsdoc", le0nik/lodash"]
}

ES5, node and react(with jsx):

{
  "extends": ["le0nik/legacy", "le0nik/node" "le0nik/react]
}

Override config rule:

Overrides quotes: [2, "single"]

{
  "extends": ["le0nik"],
  "rules": {
    "quotes": [2, "double"],
  }
}

Note for eslint-plugin-import rule, if you use default or legacy config.

It has import/no-unresolved rule enabled and by default uses Node.js resolver.

If you are going to use webpack with loaders specified in require/import, then you might want to install eslint-import-resolver-webpack.

If you use another module bundler, that lets you use custom paths in require/import, then you might want to read this.

Or you can disable this rule entirely, although I find it very useful.

{
  "extends": [
    "le0nik" // or "le0nik/legacy"
  ],
  "rules": {
    "import/no-unresolved": 0
  }
}
