Catùfol

A helper tool on the top of Webpack, Karma, TypeScript and other tools that helps to reduce configuration steps. The tool will try to work with a minimum of configuration and will use conventions and other project files to extract configuration settings whenever it's possible.

About the name

Catùfol is a Catalan word that is used to name the pots or containers that ares used to carry water in a water wheel or noria. There is also a Romainan word (without the accent) that means potato. You can chose whichever meaning you like more :)

Conventions

Catùfol relays on folder structure and file name conventions in order to work properly. The main idea is to minimize configuration settings, as a trade off, we need to follow some conventions on how we structure our app.

Folders

yourApp/
├── app/                     // Here goes all your app code
│   ├── main.ts              // Your entry point file for Webpack
│   ├── helloTest.spec.ts    // Test files are expected to have the extension .spec.ts
│   └── index.html           // This is the HTML template used to generate the final index.html on your build
├── coverage/                // Generated folder. Coverage reports will be created here
├── build/                   // Generated folder. Your packaged files will be created here
├── typings/                 // Generated folder. Typings use this folder for type definitions
├── node_modules/            // Generated folder. NPM use this folder for keeping dependencies
├── catufol.json             // Catufol configuration file
├── package.json             // NPM configuration file
├── typings.json             // Typings configuration file
├── test.loader.json         // Karma entry point
└── tsconfig.json            // Configuration for the Typescript compiler

app contains all the source files, including tests
build will be used for generated files and its content will be deleted on every build. It should not be versioned
coverage will contain the test coverage reports and it should also be ignored from version control

As a general rule, avoid creating your own content in generated folders or files as they can be overwritten by different tools.

Files

app/main.ts entry point for the application
app/index.html template to be used to generate the index.html file for loading the app
test.loader.js entry point for Karma

Dependencies

Webpack This project is sort of a Webpack wrapper, without it, it doesn't make too much sense
TypeScript This project is very opinionated on languages and it assumes you'll use TypeScript, although it will be compatible with JavaScript sources too
Karma It is assumed that your project is using Karma to run tests. No plans to support other tools
Jasmine For now we assume your project is using Jasmine for unit tests
NodeJS 5.0 or greater

Usage

Install it with NPM:

npm install catufol

You may want to add a configuration file catufol.json:

{
  "appName": "apps",     // It will default to your project name in package.json if not provided
  "devServerPort": 8081, // Defaults to 8080, changes the webpack dev server port
  "exportJQuery": true,  // Defaults to false, when true makes jQuery available in your modules as `jQuery`, `$`, and `window.jQuery`
  "vendors": [           // Modules included here will be included in a vendors.bundle.js file instead of bundle.js
     "reflect-metadata",
     "es6-shim"
     /* ... */
  ],
  "devEntryFile": "./app/main.ts",        // It will default to ./app/main.ts if not provided
  "prodEntryFile": "./app/main-build.ts", // It will default to ./app/main.ts if not provided,
  "karmaFiles": [/* ... */]               // This can be used to insert files in the files configuration for Karma.
                                          // If you need any.By default catufol will load some needed files.
}

It may be helpful to add some scripts to your package.json file:

{
  "scripts": {
     "build": "catufol -b",
        "start": "catufol -r",
        "test:debug": "catufol -i",
        "test": "catufol -t"
        /* ... */
        }
}

Test loader file for Karma is expected to be on the root of your project and to be named test.loader.js and if you are using AngularJS 2.0 it may look like this:

Error.stackTraceLimit = 20;

var context = require.context('./app', true, /\.spec\.ts$/);
context.keys().forEach(context);
var testing = require('@angular/core/testing');
var browserDynamic = require('@angular/platform-browser-dynamic/testing');

testing.setBaseTestProviders(
    browserDynamic.TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
    browserDynamic.TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS
);

Optional loaders

Sass If you want to use Sass you will need to install a Webpack Sass Loader. A recommended version is 3.2.0. Newer versions will use Webpack 2.0, which is not compatible with the current version of Catùfol.

Build Folder

The generated build folder will have the following structure:

build/
├── yourApp/                            // The folder will be named with the same name you used in catufol.json
│   └── bundles/
│       ├── bundle.[sha].js             // Bundled file for your app
│       ├── bundle.[sha].js.map         // Source map for your main bundle file
│       ├── vendor.bundle.[sha].js      // Vendors code bundle
│       └── vendor.bundle.[sha].js.map  // Sourcmap for vendors code
├── buildinfo.json                      // A file containing details about the build
└── index.html                          // HTML that will work as your entry point

CLI options

-t --test will run unit tests once using PhantomJS. Commonly used in CI environments
-i --interactive will run tests in interactive mode using Chrome
-hl --headless will run tests using headless Chrome
-r --run will run Webpack Development Server
-b --build will create the final artifacts using Webpack
