# Client code documentation
|
||
|
|
|
||
|
|
The client is a HTML/CSS/JavaScript web application (single page application -> SPA) developed with [TypeScript](https://www.typescriptlang.org/)/[Angular](https://angular.io/).
|
||
|
|
|
||
|
|
|
||
|
|
## Technologies
|
||
|
|
|
||
|
|
* [TypeScript](https://www.typescriptlang.org/) -> Language
|
||
|
|
* [Angular](https://angular.io) -> JavaScript framework
|
||
|
|
* [SASS](http://sass-lang.com/) -> CSS framework
|
||
|
|
* [Webpack](https://webpack.js.org/) -> Source builder (compile TypeScript, SASS files, bundle them...)
|
||
|
|
* [Bootstrap](http://getbootstrap.com/) -> CSS framework
|
||
|
|
* [WebTorrent](https://webtorrent.io/) -> JavaScript library to make P2P in the browser

## Files
|
||
|
|
|
||
|
|
The client files are in the `client` directory. The Webpack 2 configurations files are in `client/config` and the source files in `client/src`.
|
||
|
|
The client modules description are in the [client/package.json](https://github.com/Chocobozzz/PeerTube/blob/master/client/package.json). There are many modules that are used to compile the web application in development or production mode.
|
||
|
|
Here is the description of the useful `client` files directory:
|
||
|
|
|
||
|
|
tslint.json -> TypeScript linter rules
|
||
|
|
tsconfig.json -> TypeScript configuration for the compilation
|
||
|
|
.bootstraprc -> Bootstrap configuration file (which module we need)
|
||
|
|
config -> Webpack configuration files
|
||
|
|
src
|
||
|
|
|__ app -> TypeScript files for Angular application
|
||
|
|
|__ assets -> static files (images...)
|
||
|
|
|__ sass -> SASS files that are global for the application
|
||
|
|
|__ standalone -> files outside the Angular application (embed HTML page...)
|
||
|
|
|__ index.html -> root HTML file for our Angular application
|
||
|
|
|__ main.ts -> Main TypeScript file that boostraps our Angular application
|
||
|
|
|__ polyfills.ts -> Polyfills imports (ES 2015...)
|
||
|
|
|
||
|
|
Details of the Angular application file structure. It tries to follow [the official Angular styleguide](https://angular.io/docs/ts/latest/guide/style-guide.html).

|
|
app
|
||
|
|
|__ +admin -> Admin components (followers, users...)

|__ signup -> Signup form
|
||
|
|
|__ videos -> Video components (list, watch, upload...)
|
||
|
|
|__ app.component.{html,scss,ts} -> Main application component
|
||
|
|
|__ app-routing.module.ts -> Main Angular routes
|
||
|
|
|__ app.module.ts -> Angular root module that imports all submodules we need
|

|
|
|
||
|
|
## Conventions
|
||
|
|
|
||
|
|
Uses [TSLint](https://palantir.github.io/tslint/) for TypeScript linting and [Angular styleguide](https://angular.io/docs/ts/latest/guide/style-guide.html).

## Developing
|
||
|
|
|
||
|
|
* Install [the dependencies](https://github.com/Chocobozzz/PeerTube#dependencies)
|
||
|
|
* Run `yarn install --pure-lockfile` at the root directory to install all the dependencies
|
||
|
|
* Run PostgreSQL and create the database `peertube_dev`.
|
||
|
|
* Run `npm run dev:client` to compile the client, run the server, watch client files modifications and reload modules on the fly (you don't need to refresh manually the web browser). The API listen on `localhost:9000` and the client on `localhost:3000`.
|
||
|
|
|
||
|
|
In a Angular application, we create components that we put together. Each component is defined by an HTML structure, a TypeScript file and optionally a SASS file.
|
||
|
|
If you are not familiar with Angular I recommend you to read the [quickstart guide](https://angular.io/docs/ts/latest/quickstart.html).

The main client component is `app.component.ts`. You can begin to look at this file. Then you could navigate in the different submodules to see how components are built.
