Plugins and Extensions

This config includes the following plugins and extensions:

• eslint-config-twilio-base
• prettier
• eslint-plugin-import
• eslint-plugin-no-only-tests
• eslint-plugin-sonarjs

Installation

$ npm install eslint eslint-config-twilio --save-dev

Usage

Add the ESLint config to either your package.json or your .eslintrc:

package.json

{
  "name": "my-project",
  "eslintConfig": {
    "extends": [
      "twilio"
    ]
  }
}

.eslintrc

{
  "extends": [
    "twilio"
  ]
}

Then add the following two scripts for running and fixing your codebase:

{
  "scripts": {
    "lint": "eslint --ext js src/",
    "lint:fix": "npm run lint -- --fix"
  }
}

Prettier

This package makes use of Prettier for setting specific code formatting rules in your project.

If you want to allow your IDE to auto-format your code as you save it, then create a .prettierrc.js and import the base configuration from the eslint-config-twilio.

const baseConfig = require('./node_modules/eslint-config-twilio/rules/prettier');

module.exports = {
  ...baseConfig,
};

You might also want to edit/extend those rules according to your project style-guide. To do that, you will need to make ESLint aware of the changes.

From your .eslintrc file, add the following override rules:

"prettier/prettier": ["warn", {}, {
  "usePrettierrc": true
}],
