eslint-plugin-figma-plugins

This repository defines typescript-eslint rules for Figma plugin development.

This tool helps you stay up to date with best practices and deprecations in the Figma Plugin API. You can use it to help identify, and in many cases automatically fix, issues in your plugin code. Like any ESLint plugin, it integrates with IDEs like VSCode to provide inline warnings and quick-fix functionality.

A quick look

Installation

Dependencies

This linter requires TypeScript, ESLint, typescript-eslint, and the Figma Plugin API type definitions. To install all of these, run:

npm install -D typescript eslint@8 @typescript-eslint/parser@6 @typescript-eslint/eslint-plugin@6 @figma/plugin-typings

Notes on peer dependency versions

• This plugin is not yet compatible with ESLint 9. Once typescript-eslint has been upgraded to support ESLint 9, we'll update this README with example configurations that use the new ESLint 9 flat configs.
• This plugin has only been tested with typescript-eslint version 6.

Install the ESLint plugin package

npm install -D @figma/eslint-plugin-figma-plugins

Configure eslint

Configure typescript-eslint as normal using these instructions.

Next, update your ESLint config's extends array to include the plugin:@figma/figma-plugins/recommended ruleset. We also recommend the following rulesets:

• eslint:recommended,
• plugin:@typescript-eslint/recommended

To work with TypeScript code, ESLint also requires the following parser settings:

{
  ...
  parser: '@typescript-eslint/parser',
  parserOptions: {
    project: './tsconfig.json',
  },
  ...
}

Here's a full example of .eslintrc.js:

/* eslint-env node */
module.exports = {
  extends: [
    'eslint:recommended',
    'plugin:@typescript-eslint/recommended',
    'plugin:@figma/figma-plugins/recommended',
  ],
  parser: '@typescript-eslint/parser',
  parserOptions: {
    project: './tsconfig.json',
  },
  root: true
}

Restart the ESLint server

If you've run npm install and updated to a newer version of this package, remember to restart your IDE. In VSCode, you can restart the ESLint server independently by opening the command palette and choosing "Restart ESLint Server".

Usage

Linting and autofixing

You can lint your project using these rules by running

npx eslint ./path/to/source

Some rules provide autofixes, which you can run using --fix.

npx eslint --fix ./path/to/source

Autofixes are also available via some IDEs.

VSCode

To use ESLint with VSCode, see the ESLint VSCode extension. This extension will show rule violations inline, as well as provide opportunities to run autofixes directly in the IDE.
