2 | ||
3 | Interested in contributing? Awesome! | |

5 | **This guide will present you the following contribution topics:** | |
6 | ||
7 | * [Translate](#translate) | |
8 | * [Give your feedback](#give-your-feedback) | |
9 | * [Write documentation](#write-documentation) | |
10 | * [Develop](#develop) | |
11 | * [Improve the website](#improve-the-website) | |
12 | ||
13 | ## Translate | |
14 | ||
15 | You can help us to translate the PeerTube interface to many languages! See [the documentation](/support/doc/translation.md) to know how. | |
16 | ||
17 | ||
18 | ## Give your feedback | |
19 | ||
20 | You don't need to know how to code to start contributing to PeerTube! Other | |
21 | contributions are very valuable too, among which: you can test the software and | |
22 | report bugs, you can give feedback on potential bugs, features that you are | |
23 | interested in, user interface, design, decentralized architecture... | |
24 | ||
25 | ||
26 | ## Write documentation | |
27 | ||
28 | You can help to write the documentation of the REST API, code, architecture, | |
29 | demonstrations. | |
30 | ||
31 | For the REST API you can see the documentation in [/support/doc/api](/support/doc/api) directory. | |
32 | 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. | |
33 | ||
34 | Some hints: | |
35 | * Routes are defined in [/server/controllers/](/server/controllers/) directory | |
36 | * Parameters validators are defined in [/server/middlewares/validators](/server/middlewares/validators) directory | |
37 | * Models sent/received by the controllers are defined in [/shared/models](/shared/models) directory | |
38 | ||

40 | ## Improve the website | |
41 | ||
42 | 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. | |
43 | ||
44 | You can help us improve it too! | |
45 | ||
46 | 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 | |
47 | ||
48 | ||
49 | ## Develop | |
50 | ||
51 | Don't hesitate to talk about features you want to develop by creating/commenting an issue | |
52 | before you start working on them :). | |
53 | ||
54 | ### Prerequisites | |
55 | ||
56 | First, you should use a server or PC with at least 4GB of RAM. Less RAM may lead to crashes. | |
57 | ||
58 | Make sure that you have followed | |
59 | [the steps](/support/doc/dependencies.md) | |
60 | to install the dependencies. | |
61 | ||
62 | Fork the github repository, | |
63 | and then clone the sources and install node modules: | |
64 | ||
65 | ``` | |
66 | $ git clone https://github.com/YOUR_GITHUB_USERNAME/PeerTube | |
67 | $ cd PeerTube | |
68 | $ yarn install --pure-lockfile | |
69 | ``` | |
70 | ||
71 | Note that development is done on the `develop` branch. If you want to hack on | |
72 | Peertube, you should switch to that branch. Also note that you have to repeat | |
73 | the `yarn install --pure-lockfile` command. | |
74 | ||
75 | Then, create a postgres database and user with the values set in the | |
76 | `config/default.yaml` file. For instance, if you do not change the values | |
77 | there, the following commands would create a new database called `peertube_dev` | |
78 | and a postgres user called `peertube` with password `peertube`: | |
79 | ||
80 | ``` | |
81 | # sudo -u postgres createuser -P peertube | |
82 | Enter password for new role: peertube | |
83 | # sudo -u postgres createdb -O peertube peertube_dev | |
84 | ``` | |
85 | ||
86 | Then enable extensions PeerTube needs: | |
87 | ||
88 | ``` | |
89 | $ sudo -u postgres psql -c "CREATE EXTENSION pg_trgm;" peertube_dev | |
90 | $ sudo -u postgres psql -c "CREATE EXTENSION unaccent;" peertube_dev | |
91 | ``` | |
92 | ||
93 | In dev mode, administrator username is **root** and password is **test**. | |
94 | ||
95 | ### Online development | |
96 | ||
97 | You can get a complete PeerTube development setup with Gitpod, a free one-click online IDE for GitHub: | |
98 | ||
99 | [![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#https://github.com/Chocobozzz/PeerTube) | |
100 | ||
101 | ### Server side | |
102 | ||
103 | You can find a documentation of the server code/architecture [here](https://docs.joinpeertube.org/#/contribute-architecture?id=server-code). | |
104 | ||
105 | To develop on the server-side: | |
106 | ||
107 | ``` | |
108 | $ npm run dev:server | |
109 | ``` | |
110 | ||
111 | Then, the server will listen on `localhost:9000`. When server source files | |
112 | change, these are automatically recompiled and the server will automatically | |
113 | restart. | |
114 | ||
115 | ### Client side | |
116 | ||
117 | You can find a documentation of the client code/architecture | |
118 | [here](https://docs.joinpeertube.org/#/contribute-architecture?id=client-code). | |
119 | ||
120 | ||
121 | To develop on the client side: | |
122 | ||
123 | ``` | |
124 | $ npm run dev:client | |
125 | ``` | |
126 | ||
127 | The API will listen on `localhost:9000` and the frontend on `localhost:3000`. | |
128 | Client files are automatically compiled on change, and the web browser will | |
129 | reload them automatically thanks to hot module replacement. | |
130 | ||
131 | ### Client and server side | |
132 | ||
133 | The API will listen on `localhost:9000` and the frontend on `localhost:3000`. | |
134 | File changes are automatically recompiled, injected in the web browser (no need to refresh manually) | |
135 | and the web server is automatically restarted. | |
136 | ||
137 | ``` | |
138 | $ npm run dev | |
139 | ``` | |
140 | ||
141 | ### Testing the federation of PeerTube servers | |
142 | ||
143 | Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user. | |
144 | Then, we can create the databases (if they don't already exist): | |
145 | ||
146 | ``` | |
147 | $ sudo -u postgres createuser you_username --createdb | |
148 | $ createdb -O peertube peertube_test{1,2,3} | |
149 | ``` | |
150 | ||
151 | Build the application and flush the old tests data: | |
152 | ||
153 | ``` | |
154 | $ npm run build -- --light | |
155 | $ npm run clean:server:test | |
156 | ``` | |
157 | ||
158 | This will run 3 nodes: | |
159 | ||
160 | ``` | |
161 | $ npm run play | |
162 | ``` | |
163 | ||
164 | Then you will get access to the three nodes at `http://localhost:900{1,2,3}` | |
165 | with the `root` as username and `test{1,2,3}` for the password. | |
166 | ||
167 | Instance configurations are in `config/test-{1,2,3}.yaml`. | |
168 | ||
169 | ### Unit tests | |
170 | ||
171 | Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user. | |
172 | ||
173 | Then, we can create the databases (if they don't already exist): | |
174 | ||
175 | ``` | |
176 | $ sudo -u postgres createuser you_username --createdb --superuser | |
177 | $ createdb -O peertube peertube_test{1,2,3,4,5,6} | |
178 | ``` | |
179 | ||
180 | Build the application and run the unit/integration tests: | |
181 | ||
182 | ``` | |
183 | $ npm run build | |
184 | $ npm test | |
185 | ``` | |
186 | ||
187 | If you just want to run 1 test: | |
188 | ||
189 | ``` | |
190 | $ npm run mocha -- --exit --require ts-node/register/type-check --bail server/tests/api/index.ts | |
191 | ``` | |
192 | ||
193 | Instance configurations are in `config/test-{1,2,3,4,5,6}.yaml`. | |
194 | Note that only instance 2 has transcoding enabled. |
