eslint-config-ts-mailonline

MailOnline ESlint Typescript configuration.

Usage

1. Add eslint-config-ts-mailonline, eslint, typescript, prettier, husky, and pretty-quick as development dependencies:

yarn add --dev eslint-config-ts-mailonline eslint typescript prettier husky pretty-quick

2. Create a tsconfig.eslint.json file (this is a technicality due to the way the eslint typescript parser works):

{
  "compilerOptions": {"strict": true},
  "include": ["**/*.js", "**/*.jsx", "**/*.ts", "**/*.tsx"],
  "exclude": ["node_modules", "dist", "coverage"]
}

3. Create ESLint configuration file (.eslintrc.json) that extends ts-mailonline:

{
  "extends": ["ts-mailonline", "ts-mailonline/react"],
  "parserOptions": {
    "project": "./tsconfig.eslint.json"
  }
}

4. Create prettier.config.js on the root of your project with these contents:

module.exports = require('eslint-config-ts-mailonline/prettier');

5. Create an .eslintignore file:

bin/
dist/
coverage/
dev/
node_modules/
*.css.d.ts

6. Add the following script command to your package.json:

{
  "lint": "tsc --noEmit && eslint './**/*.{js,jsx,ts,tsx}'"
}

7. Add the following pre-commit hook to your husky pre-commit script:

pretty-quick --staged && yarn run lint
