@esri/eslint-plugin-calcite-components

ESLint rules specific to Stencil JS projects.

Installation

Install the following deps in your stencil project:

npm i @esri/eslint-plugin-calcite-components --save-dev

Usage

Add or update the .eslintrc.json configuration file:

{
  "parserOptions": {
    "project": "./tsconfig.json"
  },
  "extends": ["plugin:@esri/calcite-components/recommended"]
}

Add a new lint script to package.json:

{
  "scripts": {
    "lint": "eslint src/**/*{.ts,.tsx}"
  }
}

Then you can run the linter:

npm run lint

Supported Rules

• @esri/calcite-components/ban-events

This rule helps prevent usage of specific events and allows suggesting alternatives.

• @esri/calcite-components/ban-props-on-host

This rule catches props/attributes that should be in the encapsulated HTML structure and not on the host element.

• @esri/calcite-components/enforce-ref-last-prop

This ensures the node passed into the ref callback is in sync with its JSX attributes/properties when invoked.

• @esri/calcite-components/require-event-emitter-type

This rule helps enforce the payload type to EventEmitters to avoid misleading any type on the CustomEvent detail object.

• @esri/calcite-components/strict-boolean-attributes

This rule catches boolean props that are initialized in a way that does not conform to the HTML5 spec.

{
  "@esri/calcite-components/ban-props-on-host": "error",
  "@esri/calcite-components/enforce-ref-last-prop": "error",
