eslint-plugin-lit
ESLint plugin for Lit.
Install
Assuming you already have ESLint installed, run:
1# npm 2npm install eslint-plugin-lit --save-dev 3 4# yarn 5yarn add eslint-plugin-lit --dev
Usage
Then extend the recommended eslint config:
1{ 2 "extends": [ 3 // ... 4 "plugin:lit/recommended" 5 ] 6}
Or if you're using (flat) config files, add to your eslint.config.js:
1import {configs} from 'eslint-plugin-lit'; 2 3export default [ 4 configs['flat/recommended'], 5 6 // or if you want to specify `files`, or other options 7 { 8 ...configs['flat/recommended'], 9 files: ['test/**/*.js'] 10 } 11];
You can also specify settings that will be shared across all the plugin rules.
1{ 2 settings: { 3 lit: { 4 elementBaseClasses: ['ClassExtendingLitElement'] // Recognize `ClassExtendingLitElement` as a sub-class of LitElement 5 } 6 } 7}
Custom Configuration
If you want more fine-grained configuration, you can instead add a snippet like this to your ESLint configuration file:
1{ 2 "plugins": [ 3 // ... 4 "lit" 5 ], 6 "rules": { 7 // ... 8 "lit/no-legacy-template-syntax": "error", 9 "lit/no-template-arrow": "warn" 10 } 11}
List of supported rules
- lit/attribute-names
- lit/attribute-value-entities
- lit/ban-attributes
- lit/binding-positions
- lit/lifecycle-super
- lit/no-classfield-shadowing
- lit/no-duplicate-template-bindings

Shareable configurations
Recommended
This plugin exports a recommended configuration that enforces Lit good practices.
To enable this configuration use the extends property in your .eslintrc config file:
1{ 2 "extends": ["eslint:recommended", "plugin:lit/recommended"] 3}
Usage with eslint-plugin-wc
We highly recommend you also depend on eslint-plugin-wc as it will provide additional rules for web components in general:
1npm i -D eslint-plugin-wc
Then extend the recommended eslint config:
1{ 2 "extends": ["plugin:wc/recommended", "plugin:lit/recommended"] 3}
