## Files
-The server main file is [server.js](https://github.com/Chocobozzz/PeerTube/blob/master/server.js).
+The server main file is [server.ts](https://github.com/Chocobozzz/PeerTube/blob/master/server.ts).
The server modules description are in the [package.json](https://github.com/Chocobozzz/PeerTube/blob/master/package.json) at the project root.
All other server files are in the [server](https://github.com/Chocobozzz/PeerTube/tree/master/server) directory:
- server.js -> app initilization, main routes configuration (static routes...)
+ server.ts -> app initilization, main routes configuration (static routes...)
config -> server YAML configurations (for tests, production...)
scripts -> Scripts files for npm run
server
* Install [the dependencies](https://github.com/Chocobozzz/PeerTube#dependencies)
* Run `npm install` at the root directory to install all the dependencies
* Run PostgreSQL and create the database `peertube_dev`.
- * Run `npm run dev` to compile the client and automatically run the server. If the client files are already compiled you can simply run `NODE_ENV=test node server`
+ * Run `npm run dev:server` to compile the client, run the server and watch server files modifications.
-The `NODE_ENV=test` is set to speed up communications between pods (see [constants.js](https://github.com/Chocobozzz/PeerTube/blob/master/server/initializers/constants.js)).
+The `NODE_ENV=test` is set to speed up communications between pods (see [constants.ts](https://github.com/Chocobozzz/PeerTube/blob/master/server/initializers/constants.ts)).
`npm run help` gives you all available commands.
