Activity 7: Putting It All Together

Solution

1. Install the developer dependencies listed in the linting exercise (eslint, prettier, eslint-config-airbnb-base, eslint-config-prettier, eslint-plugin-jest, and eslint-plugin-import):

   npm install --save-dev eslint prettier eslint-config-airbnb-base eslint-config-prettier eslint-plugin-jest eslint-plugin-import

2. Add an eslint configuration file, .eslintrc, which contains the following:

   {
    "extends": ["airbnb-base", "prettier"],
     "parserOptions": {
       "ecmaVersion": 2018,
       "sourceType": "module"
     },
     "env": {
       "browser": true,
       "node": true,
       "es6": true,
       "mocha": true,
       "jest": true
     ...
