We would ❤️ for you to contribute to Appwrite and help make it better! We want contributing to Appwrite to be fun, enjoyable, and educational for anyone and everyone. All contributions are welcome, including issues, new docs as well as updates and tweaks, blog posts, workshops, and more.
If you are worried or don’t know where to start, check out our next section explaining what kind of help we could use and where can you get involved. You can reach out with questions to [Eldad Fux (@eldadfux)](https://twitter.com/eldadfux) or [@appwrite](https://twitter.com/appwrite) on Twitter, and anyone from the [Appwrite team on Discord](https://discord.gg/GSeTUeA). You can also submit an issue, and a maintainer can guide you!
Fortheinitialstart, fork the project andusegitclonecommandtodownloadtherepositorytoyourcomputer. A standard procedure for working on an issue would be to:
4. Before you push your changes, make sure your code follows the `PSR12` coding standards , which is the standard Appwrite follows currently. You can easily do this by running the formatter.
This will give you a list of errors for you to rectify , if there is an instance you need more information on the errors being displayed you can pass in additional command line arguments. More list of available arguments can be found [here](https://github.com/squizlabs/PHP_CodeSniffer/wiki/Usage). A very useful command line argument is `--report=diff`. This will give you the expected changes by the linter for easy fixing of formatting issues.
To set up a working **development environment**, just fork the project git repository and install the backend and frontend dependencies using the proper package manager and create run the docker-compose stack.
> If you just want to install Appwrite for day-to-day usage and not as a code maintainer use this [installation guide](https://github.com/appwrite/appwrite#installation).
Please note that these instructions are for setting a functional dev environment. If you want to set up an Appwrite instance to integrate into your app, you should probably try and install Appwrite by using the instructions in the [getting started guide](https://appwrite.io/docs/getting-started-for-web) or in the main [README](README.md) file.
To get proper autocompletion for all the different functions and classes in the codebase, you'll need to install Appwrite dependencies on your local machine. You can easily do that with PHP's package manager, [Composer](https://getcomposer.org/). If you don't have Composer installed, you can use the Docker Hub image to get the same result:
Appwrite uses an internal micro-framework called Litespeed.js to build simple UI components in vanilla JS and [less](http://lesscss.org/) for compiling CSS code. To apply any of your changes to the UI, use the `gulp build` or `gulp less` commands, and restart the Appwrite main container to load the new static files to memory using `docker compose restart appwrite`.
We love to create issues that are good for beginners and label them as `good first issue` or `hacktoberfest`, but some more advanced topics might require extra knowledge. Below is a list of links you can use to learn more about some of the more advance topics that will help you master the Appwrite codebase.
- [TCP vs UDP](https://www.guru99.com/tcp-vs-udp-understanding-the-difference.html#:~:text=TCP%20is%20a%20connection%2Doriented,speed%20of%20UDP%20is%20faster&text=TCP%20does%20error%20checking%20and,but%20it%20discards%20erroneous%20packets.)
- [Microservices vs Monolithic](https://www.mulesoft.com/resources/api/microservices-vs-monolithic#:~:text=Microservices%20architecture%20vs%20monolithic%20architecture&text=A%20monolithic%20application%20is%20built%20as%20a%20single%20unit.&text=To%20make%20any%20alterations%20to,formally%20with%20business%2Doriented%20APIs.)
Appwrite's current structure is a combination of both [Monolithic](https://en.wikipedia.org/wiki/Monolithic_application) and [Microservice](https://en.wikipedia.org/wiki/Microservices) architectures, but our final goal, as we grow, is to be using only microservices.
Appwrite's main API container is designed as a monolithic app. This is a decision we made to allow us to develop the project faster while still being a very small team.
Although the Appwrite API is a monolithic app, it has a very clear separation of concern as each internal service or worker is separated by its container, which will allow us as we grow to start breaking services for better maintenance and scalability.
### The Microservice Part
Each container in Appwrite is a microservice on its own. Each service is an independent process that can scale without regard to any of the other services.
Currently, all of the Appwrite microservices are intended to communicate using the TCP protocol over a private network. You should be aware to not expose any of the services to the public-facing network, besides the public port 80 and 443, who, by default, are used to expose the Appwrite HTTP API.
Appwrite dev version uses ports 80 and 443 as an entry point to the Appwrite API and console. We also expose multiple ports in the range of 9500-9504 for debugging some of the Appwrite containers on dev mode. If you have any conflicts with the ports running on your system, you can easily replace them by editing Appwrite's docker-compose.yml file and executing `docker compose up -d` command.
To start helping us to improve the Appwrite server by submitting code, prior knowledge of Appwrite's technology stack can help you with getting started.
Appwrite stack is combined from a variety of open-source technologies and tools. Appwrite backend API is written primarily with PHP version 7 and above on top of the [Utopia PHP framework](https://github.com/utopia-php/framework). The Appwrite frontend is built with tools like gulp, less, and [litespeed.js](https://github.com/litespeed-js). We use Docker as the container technology to package the Appwrite server for easy integration on-cloud, on-premise, or on-localhosts.
Appwrite uses a package manager for managing code dependencies for both backend and frontend development. We try our best to avoid creating any unnecessary, and any new dependency to the project is subjected to a lead developer review and approval.
Many of Appwrite's internal modules are also used as dependencies to allow other Appwrite's projects to reuse them and as a way to contribute them back to the community.
Appwrite uses [PHP's Composer](https://getcomposer.org/) for managing dependencies on the server-side and [JS NPM](https://www.npmjs.com/) for managing dependencies on the frontend side.
Appwrite is following the [PHP-FIG standards](https://www.php-fig.org/). Currently, we are using both PSR-0 and PSR-12 for coding standards and autoloading standards.
We wish Appwrite will be as easy to set up and in a single, localhost, and easy to grow to a large environment with dozens and even hundreds of instances.
Please avoid introducing new dependencies to Appwrite without consulting the team. New dependencies can be very helpful but also introduce new security and privacy issues, complexity, and impact total docker image size.
We would 💖 you to contribute to Appwrite, but we would also like to make sure Appwrite is as great as possible and loyal to its vision and mission statement 🙏.
This is also important for the Appwrite lead developers to be able to give technical input and different emphasis regarding the feature design and architecture. Some bigger features might need to go through our [RFC process](https://github.com/appwrite/rfc).
The Runtimes for all supported cloud functions (multicore builds) can be found at the [open-runtimes/open-runtimes](https://github.com/open-runtimes/open-runtimes) repository.
1. Update the console spec file located at `app/config/specs/swagger2-<version-number>.console.json` using Appwrite Tasks. Run the `php app/cli.php specs <version-number> normal` command in a running `appwrite/appwrite` container.
2. Generate a new SDK using the command `php app/cli.php sdks`
Appwrite uses [yasd](https://github.com/swoole/yasd) debugger, which can be made available during build of Appwrite. You can connect to the debugger using VS Code [PHP Debug](https://marketplace.visualstudio.com/items?itemName=felixfbecker.php-debug) extension or if you are in PHP Storm you don't need any plugin. Below are the settings required for remote debugger connection.
First, you need to create an init file. Duplicate **dev/yasd_init.php.stub** file and name it **dev/yasd_init.php** and there change the IP address to your development machine's IP. Without the proper IP address debugger wont connect. And you also need to set **DEBUG** build arg in **appwrite** service in **docker-compose.yml** file.
In settings, go to **Languages & Frameworks** > **PHP** > **Debug**, there under **Xdebug** set the debug port to **9005** and enable **can accept external connections** checkbox.
You can use WRK Docker image to benchmark the server performance. Benchmarking is extremely useful when you want to compare how the server behaves before and after a change has been applied. Replace [APPWRITE_HOSTNAME_OR_IP] with your Appwrite server hostname or IP. Note that localhost is not accessible from inside the WRK container.
From time to time, our team will add tutorials that will help contributors find their way in the Appwrite source code. Below is a list of currently available tutorials:
