1 | # Client code documentation | |
2 | ||
3 | The client is a HTML/CSS/JavaScript web application (single page application -> SPA) developed with [TypeScript](https://www.typescriptlang.org/)/[Angular](https://angular.io/). | |
4 | ||
5 | ||
6 | ## Technologies | |
7 | ||
8 | * [TypeScript](https://www.typescriptlang.org/) -> Language | |
9 | * [Angular](https://angular.io) -> JavaScript framework | |
10 | * [SASS](http://sass-lang.com/) -> CSS framework | |
11 | * [Webpack](https://webpack.js.org/) -> Source builder (compile TypeScript, SASS files, bundle them...) | |
12 | * [Bootstrap](http://getbootstrap.com/) -> CSS framework | |
13 | * [WebTorrent](https://webtorrent.io/) -> JavaScript library to make P2P in the browser | |
14 | * [VideoJS](http://videojs.com/) -> JavaScript player framework | |

17 | ## Files | |
18 | ||
19 | The client files are in the `client` directory. The Webpack 2 configurations files are in `client/config` and the source files in `client/src`. | |
20 | The client modules description are in the [client/package.json](/client/package.json). There are many modules that are used to compile the web application in development or production mode. | |
21 | Here is the description of the useful `client` files directory: | |
22 | ||
23 | tslint.json -> TypeScript linter rules | |
24 | tsconfig.json -> TypeScript configuration for the compilation | |
25 | .bootstraprc -> Bootstrap configuration file (which module we need) | |
26 | config -> Webpack configuration files | |
27 | src | |
28 | |__ app -> TypeScript files for Angular application | |
29 | |__ assets -> static files (images...) | |
30 | |__ sass -> SASS files that are global for the application | |
31 | |__ standalone -> files outside the Angular application (embed HTML page...) | |
32 | |__ index.html -> root HTML file for our Angular application | |
33 | |__ main.ts -> Main TypeScript file that boostraps our Angular application | |
34 | |__ polyfills.ts -> Polyfills imports (ES 2015...) | |
35 | ||
36 | 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). | |
37 | ||
38 | app | |
39 | |__ +admin -> Admin components (followers, users...) | |
40 | |__ account -> Account components (password change...) | |
41 | |__ core -> Core components/services | |
42 | |__ header -> Header components (logo, search...) | |
43 | |__ login -> Login component | |
44 | |__ menu -> Menu component (on the left) | |
45 | |__ shared -> Shared components/services (search component, REST services...) | |
46 | |__ signup -> Signup form | |
47 | |__ videos -> Video components (list, watch, upload...) | |
48 | |__ app.component.{html,scss,ts} -> Main application component | |
49 | |__ app-routing.module.ts -> Main Angular routes | |
50 | |__ app.module.ts -> Angular root module that imports all submodules we need | |
51 | ||
52 | ## Conventions | |
53 | ||
54 | Uses [TSLint](https://palantir.github.io/tslint/) for TypeScript linting and [Angular styleguide](https://angular.io/docs/ts/latest/guide/style-guide.html). | |
55 | ||
56 | ## Concepts | |
57 | ||
58 | 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. | |
59 | If you are not familiar with Angular I recommend you to read the [quickstart guide](https://angular.io/docs/ts/latest/quickstart.html). | |

61 | ## Components tree | |

64 | ||
65 | ## Newcomers | |
66 | ||
67 | 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. |
