eslint-config-twilio-ts

Twilio's approach to TypeScript styling.

Plugins and Extensions

This config includes the following plugins and extensions:

• eslint-config-twilio
• @typescript-eslint

Installation

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

Usage

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

package.json

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

.eslintrc

{
  "extends": [
    "twilio-ts"
  ]
}

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

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

Enabling React

To enable React linting in TypeScript, also install eslint-config-twilio-react and add twilio-react as an extension to your ESLint Config file. Then update the lint script to:

{
  "scripts": {
    "lint": "eslint --ext ts --ext tsx src/"
  }
}

.eslintrc

NOTE: twilio-ts should come after twilio-react because twilio-ts overrides conflicting rules:

{
  "extends": [
    "twilio-react",
    "twilio-ts"
  ]
}

.prettier.js

If you want to allow your IDE to auto-format your code as you save it, then create a .prettierrc.js and add:

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

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