ESLint Plugin Crisp

A set of custom ESLint configurations and rules for Crisp.

😘 Maintainers: @baptistejamin, @eliottvincent

Usage

The plugin provides two configurations:

• crisp/recommended: JS rules targetting backend code (Node.js)
• crisp/recommended-vue: JS rules targetting frontend code (Vue.js)

Add the plugin in your ESLint config object, then extend the desired configuration:

{
  "plugins": [
    "eslint-plugin-crisp"
  ],

  "extends": [
    "plugin:crisp/recommended"
    // OR "plugin:crisp/recommended-vue"
  ]
}
