  29 ## Translate
  30
  31 You can help us to translate the PeerTube interface to many languages! See [the documentation](/support/doc/translation.md) to know how.
  32
  33
  34 ## Give your feedback
  35
  36 You don't need to know how to code to start contributing to PeerTube! Other
  37 contributions are very valuable too, among which: you can test the software and
  38 report bugs, you can give feedback on potential bugs, features that you are
  39 interested in, user interface, design, decentralized architecture...
  40
  41
  42 ## Write documentation
  43
  44 You can help to write the documentation of the REST API, code, architecture,
  45 demonstrations.
  46
  47 For the REST API you can see the documentation in [/support/doc/api](https://github.com/Chocobozzz/PeerTube/tree/develop/support/doc/api) directory.
  48 Then, you can just open the `openapi.yaml` file in a special editor like [http://editor.swagger.io/](http://editor.swagger.io/) to easily see and edit the documentation. You can also use [redoc-cli](https://github.com/Redocly/redoc/blob/master/cli/README.md) and run `redoc-cli serve --watch support/doc/api/openapi.yaml` to see the final result.
  49
  50 Some hints:
  51  * Routes are defined in [/server/controllers/](https://github.com/Chocobozzz/PeerTube/tree/develop/server/controllers) directory
  52  * Parameters validators are defined in [/server/middlewares/validators](https://github.com/Chocobozzz/PeerTube/tree/develop/server/middlewares/validators) directory
  53  * Models sent/received by the controllers are defined in [/shared/models](https://github.com/Chocobozzz/PeerTube/tree/develop/shared/models) directory

  56 ## Improve the website
  57
  58 PeerTube's website is [joinpeertube.org](https://joinpeertube.org), where people can learn about the project and how it works – note that it is not a PeerTube instance, but rather the project's homepage.
  59
  60 You can help us improve it too!
  61
  62 It is not hosted on GitHub but on [Framasoft](https://framasoft.org/)'s own [GitLab](https://about.gitlab.com/) instance, [FramaGit](https://framagit.org): https://framagit.org/framasoft/peertube/joinpeertube
  63
  64
  65 ## Develop
  66
  67 Always talk about features you want to develop by creating/finding and commenting the issue tackling your problem
  68 before you start working on it, and inform the community that you begin coding by claiming the issue.
  69
  70 Once you are ready to show your code to ask for feedback, submit a *draft* Pull Request.
  71 Once you are ready for a code review before merge, submit a Pull Request. In any case, please
  72 link your PR to the issues it solves by using the GitHub syntax: "fixes #issue_number".
  73
  74 ### Prerequisites
  75
  76 First, you should use a server or PC with at least 4GB of RAM. Less RAM may lead to crashes.
  77
  78 1) Make sure that you have followed
  79 [the steps](/support/doc/dependencies.md)
  80 to install the dependencies.
  81 1) Install [parallel](https://www.gnu.org/software/parallel/) to be able to run tests.
  82 1) Fork the Github repository.
  83 1) Run the following commands.
  84 ```
  85 $ git clone https://github.com/Chocobozzz/PeerTube
  86 $ cd PeerTube
  87 $ git remote add me git@github.com:YOUR_GITHUB_USERNAME/PeerTube.git
  88 $ yarn install --pure-lockfile
  89 ```
  90
  91 Note that development is done on the `develop` branch. If you want to hack on
  92 Peertube, you should switch to that branch. Also note that you have to repeat
  93 the `yarn install --pure-lockfile` command.
  94
  95 When you create a new branch you should also tell to use your repo for upload
  96 not default one. To do just do:
  97 ```
  98 $ git push --set-upstream me <your branch name>
  99 ```
 100
 101 Then, create a postgres database and user with the values set in the
 102 `config/default.yaml` file. For instance, if you do not change the values
 103 there, the following commands would create a new database called `peertube_dev`
 104 and a postgres user called `peertube` with password `peertube`:
 105
 106 ```
 107 # sudo -u postgres createuser -P peertube
 108 Enter password for new role: peertube
 109 # sudo -u postgres createdb -O peertube peertube_dev
 110 ```
 111
 112 Then enable extensions PeerTube needs:
 113
 114 ```
 115 $ sudo -u postgres psql -c "CREATE EXTENSION pg_trgm;" peertube_dev
 116 $ sudo -u postgres psql -c "CREATE EXTENSION unaccent;" peertube_dev
 117 ```
 118
 119 In dev mode, administrator username is **root** and password is **test**.
 120
 121 ### Online development
 122
 123 You can get a complete PeerTube development setup with Gitpod, a free one-click online IDE for GitHub:
 124
 125 [![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#https://github.com/Chocobozzz/PeerTube)
 126
 127 ### Server side
 128
 129 You can find a documentation of the server code/architecture [here](https://docs.joinpeertube.org/contribute-architecture?id=server-code).
 130
 131 To develop on the server-side:
 132
 133 ```
 134 $ npm run dev:server
 135 ```
 136
 137 Then, the server will listen on `localhost:9000`. When server source files
 138 change, these are automatically recompiled and the server will automatically
 139 restart.
 140
 141 ### Client side
 142
 143 You can find a documentation of the client code/architecture
 144 [here](https://docs.joinpeertube.org/contribute-architecture?id=client-code).
 145
 146
 147 To develop on the client side:
 148
 149 ```
 150 $ npm run dev:client
 151 ```
 152
 153 The API will listen on `localhost:9000` and the frontend on `localhost:3000`.
 154 Client files are automatically compiled on change, and the web browser will
 155 reload them automatically thanks to hot module replacement.
 156
 157 ### Client and server side
 158
 159 The API will listen on `localhost:9000` and the frontend on `localhost:3000`.
 160 File changes are automatically recompiled, injected in the web browser (no need to refresh manually)
 161 and the web server is automatically restarted.
 162
 163 ```
 164 $ npm run dev
 165 ```
 166
 167 ### RTL layout
 168
 169 To test RTL layout using `ar` locale:
 170
 171 ```
 172 $ npm run dev -- --ar-locale
 173 ```
 174
 175 ### Testing
 176
 177 #### Unit/integration tests
 178
 179 Your code contributions must pass the tests before they can be merged. Tests ensure most of the application behaves
 180 as expected and respect the syntax conventions. They will run upon PR submission as part of our CI, but running them beforehand yourself will get you faster feedback and save CI runner time for others.
 181
 182 See the [dedicated documentation](/support/doc/development/tests.md) to run tests locally.
 183
 184 #### Testing the federation of PeerTube servers
 185
 186 Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user.
 187 Then, we can create the databases (if they don't already exist):
 188
 189 ```
 190 $ sudo -u postgres createuser you_username --createdb
 191 $ createdb -O peertube peertube_test{1,2,3}
 192 ```
 193
 194 Build the application and flush the old tests data:
 195
 196 ```
 197 $ npm run build
 198 $ npm run clean:server:test
 199 ```
 200
 201 To run 3 nodes:
 202
 203 ```
 204 $ NODE_APP_INSTANCE=1 NODE_ENV=test npm start
 205 $ NODE_APP_INSTANCE=2 NODE_ENV=test npm start
 206 $ NODE_APP_INSTANCE=3 NODE_ENV=test npm start
 207 ```
 208
 209 Then you will get access to the three nodes at `http://localhost:900{1,2,3}`
 210 with the `root` as username and `test{1,2,3}` for the password.
 211
 212 Instance configurations are in `config/test-{1,2,3}.yaml`.
 213
 214 ### Emails
 215
 216 To test emails with PeerTube:
 217
 218  * Run [mailslurper](http://mailslurper.com/)
 219  * Run PeerTube using mailslurper SMTP port: `NODE_CONFIG='{ "smtp": { "hostname": "localhost", "port": 2500, "tls": false } }' NODE_ENV=test npm start`
 220
