eslint-config

Linting ESLint

Use ESLint to lint your es6 code.

Setup

npm init @open-wc
# Upgrade > Linting

::: tip This is part of the default open-wc recommendation :::

Manual

• yarn add --dev @open-wc/eslint-config
• Copy .eslintignore to .eslintignore
• Copy .eslintrc.js to .eslintrc.js
• Add these scripts to your package.json

  "scripts": {
    "lint:eslint": "eslint --ext .js,.html .",
    "format:eslint": "eslint --ext .js,.html . --fix"
  },

What you get

This will install @open-wc/eslint-config, a config based on airbnb but allows for some specialities needed for Web Components.

• Apply linting to js and html files
• Apply linting for best practices
• Allow dynamic module imports
• Allow imports in test/demos from devDependencies
• Allow underscore dangle
• Do not prefer default exports
• Do not prefer no file extension

Usage

Run:

• npm run lint:eslint to check if any file is not correctly formatted
• npm run format:eslint to auto format your files

<script> export default { mounted() { const editLink = document.querySelector('.edit-link a'); if (editLink) { const url = editLink.href; editLink.href = url.substr(0, url.indexOf('/master/')) + '/master/packages/eslint-config/README.md'; } } } </script>
