1. Install the preset:

   $ npm install --save-dev size-limit @size-limit/file

2. Add the size-limit section and the size script to your package.json:

   + "size-limit": [
   +   {
   +     "path": "dist/app-*.js"
   +   }
   + ],
     "scripts": {
       "build": "webpack ./webpack.config.js",
   +   "size": "npm run build && size-limit",
       "test": "jest && eslint ."
     }

3. Here’s how you can get the size for your current project:

   $ npm run size
   
     Package size: 30.08 kB with all dependencies, minified and gzipped

4. Now, let’s set the limit. Add 25% to the current total size and use that as the limit in your package.json:

     "size-limit": [
       {
   +     "limit": "35 kB",
         "path": "dist/app-*.js"
       }
     ],

5. Add the size script to your test suite:

     "scripts": {
       "build": "webpack ./webpack.config.js",
       "size": "npm run build && size-limit",
   -   "test": "jest && eslint ."
   +   "test": "jest && eslint . && npm run size"
     }

6. If you don’t have a continuous integration service running, don’t forget to add one — start with [Travis CI].
