eslint-config-leankit

eslint-config-leankit

This package provides LeanKit's .eslintrc as an extensible shared config.

Usage

We support four ESLint configurations for your usage.

eslint-config-leankit

Our default export contains the base of our ESLint legacy rules (ECMAScript 5). It currently requires only eslint.

1. npm install eslint eslint-config-leankit --save-dev
2. add "extends": "leankit" to your .eslintrc

eslint-config-leankit/es6

This exports ECMAScript 6+ features and rules. This also only requires eslint. You will probably want to extend this along with the base leankit rules.

1. npm install eslint eslint-config-leankit --save-dev
2. add "extends": [ "leankit/es6" ] to your .eslintrc or you can choose to merge the base and es6 rules "extends": [ "leankit", "leankit/es6" ]

eslint-config-leankit/react

These rules are specific to React development. It requires eslint and eslint-plugin-react.

1. npm install eslint eslint-plugin-react eslint-config-leankit --save-dev
2. add "extends": "leankit/react" to your .eslintrc or you can choose to merge the base and react rules "extends": [ "leankit", "leankit/react" ]

eslint-config-leankit/a11y

If you are using React and you'd like some Accessibility rules, then a11y is for you. It requires eslint and eslint-plugin-jsx-a11y.

1. npm install eslint eslint-plugin-jsx-a11y eslint-config-leankit --save-dev
2. add "extends": "leankit/a11y" to your .eslintrc or you can choose to merge the base and react rules "extends": [ "leankit", "leankit/a11y" ]

eslint-config-leankit/test

This some rules for writing tests using mocha.

1. npm install eslint eslint-config-leankit --save-dev
2. add "extends": "leankit/test" to your .eslintrc

Example Setup

Simple Project Using All the Rules

.
└── .eslintrc // extends: [ "leankit", "leankit/es6" ]

Complex Project with Some of the Rules

.
├── client
│   ├── js
│   │   └── .eslintrc // extends: "react"
│   └── spec
│   │   └── .eslintrc // extends: "test"
│   └── .eslintrc     // extends: "es6"
├── server
│   └── spec
│       └── .eslintrc // extends: "test"
└── .eslintrc         // extends: "leankit"

Tests

You can run tests with npm test.

You can make sure this module lints with itself using npm run lint.

Development Tips

Using npm link ../eslint-config-leankit or npm install ../eslint-config-leankit to test changes locally don't work well with this repo. Instead, use npm pack which will create a tgz file (example: eslint-config-leankit-4.5.0.tgz). From there you can install the packed file into another project (example: npm i ../eslint-config-leankit/eslint-config-leankit-4.5.0.tgz --no-save). Once installed you can run linting, but it's recommended to remove ESLint's cache first (example: rm .eslintcache && npm run lint)

eslint-config-leankit > npm pack
eslint-config-leankit > cd ../other-project
other-project > npm i ../eslint-config-leankit/eslint-config-leankit-4.5.0.tgz --no-save
other-project > rm .eslintcache && npm run lint
