Swimlane Eslint Rules

Rules for eslint used in Swimlane's Javascript (etc) development.

Javascript (es6)

Install:

npm install --save-dev eslint @swimlane/eslint-config eslint-plugin-security

Create an .eslintrc.yml file with the following:

env:
  browser: true
  commonjs: true
  es2021: true
extends:
  - '@swimlane'
parserOptions:
  ecmaVersion: 12

TypeScript

Install:

npm install --save-dev eslint @swimlane/eslint-config eslint-plugin-security
npm install --save-dev @typescript-eslint/parser @typescript-eslint/eslint-plugin

Create an .eslintrc.yml file with the following:

env:
  browser: true
  es2021: true
  node: true
extends:
  - '@swimlane/eslint-config/typescript'
parserOptions:
  ecmaVersion: 12
  sourceType: module

Prettier

If using prettier (for example @swimlane/prettier-config-swimlane) you should follow instructions in the eslint-config-prettier readme to install and setup eslint-config-prettier. For example for es6 config your .eslintrc.yml file will be:

env:
  browser: true
  commonjs: true
  es2021: true
extends:
  - '@swimlane'
  - 'prettier'
parserOptions:
  ecmaVersion: 12
