We would ❤️ 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, and 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 the next section that explains what kind of help we could use and where you can get involved. You can send your questions to @appwrite on Twitter or to anyone from the Appwrite team on Discord. You can also submit an issue, and a maintainer can guide you!
Help us keep Appwrite open and inclusive. Please read and follow our Code of Conduct.
Branch naming convention is as following
TYPE-ISSUE_ID-DESCRIPTION
example:
doc-548-submit-a-pull-request-section-to-contribution-guide
When TYPE can be:
- feat - a new feature
- doc - documentation only changes
- cicd - changes related to CI/CD system
- fix - a bug fix
- refactor - code change that neither fixes a bug nor adds a feature
All PRs must include a commit message with the description of the changes made!
For the initial start, fork the project and use git clone command to download the repository to your computer. A standard procedure for working on an issue would be to:
git pull, before creating a new branch, pull the changes from upstream. Your master needs to be up to date.
$ git pull
- Create a new branch from
masterlike:doc-548-submit-a-pull-request-section-to-contribution-guide.
$ git checkout -b [name_of_your_new_branch]
-
Work - commit - repeat (make sure you're on the correct branch!)
-
Before you push your changes, make sure your code follows the
PSR12coding standards, which is the standard that Appwrite currently follows. You can easily do this by running the formatter.
composer format <your file path>Now, go a step further by running the linter using the following command to manually fix the issues the formatter wasn't able to.
composer lint <your file path>This will give you a list of errors to rectify. If you need more information on the errors, you can pass in additional command line arguments to get more verbose information. More lists of available arguments can be found here. 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.
composer lint --report=diff <your file path>- Push changes to GitHub.
$ git push origin [name_of_your_new_branch]
- Submit your changes for review
If you go to your repository on GitHub, you'll see a
Compare & pull requestbutton. Click on that button. - Start a Pull Request
Now submit the pull request and click on
Create pull request. - Get a code review approval/reject.
- After approval, merge your PR.
- GitHub will automatically delete the branch after the merge is done. (they can still be restored).
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 use and not as a contributor, you can reference the installation guide, the getting started guide, or the main README file.
git clone [email protected]:[YOUR_FORK_HERE]/appwrite.git
cd appwrite
git submodule update --init
docker compose build
docker compose up -dTo 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. If you don't have Composer installed, you can use the Docker Hub image to get the same result:
docker run --rm --interactive --tty \
--volume $PWD:/app \
composer update --ignore-platform-reqs --optimize-autoloader --no-plugins --no-scripts --prefer-distAppwrite uses an internal micro-framework called Litespeed.js to build simple UI components in vanilla JS and less 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.
After finishing the installation process, you can start writing and editing code.
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 about the more advanced topics that will help you master the Appwrite codebase.

└── unitAppwrite'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 allows us to start breaking services for better maintenance and scalability as we grow.
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 the Appwrite microservices are intended to communicate using the TCP protocol over a private network. With the exception of the public-facing port 80 and 443, which by default are used to expose the Appwrite HTTP API, you should avoid exposing any other services' ports.
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 get started.
Appwrite stack is a combination of 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. The Appwrite frontend is built with tools like gulp, less, and litespeed.js. We use Docker as the container technology to package the Appwrite server for easy on-cloud, on-premise, or on-localhost integration.
- Redis - for managing cache and in-memory data (currently, we do not use Redis for persistent data).
- MariaDB - for database storage and queries.
- InfluxDB - for managing stats and time-series based data.
- Statsd - for sending data over UDP protocol (using Telegraf).
- ClamAV - for validating and scanning storage files.
- Imagemagick - for manipulating and managing image media files.
- Webp - for better compression of images on supporting clients.
- SMTP - for sending email messages and alerts.
- Resque - for managing data queues and scheduled tasks over a Redis server.
Appwrite uses a package manager for managing code dependencies for both backend and frontend development. We try our best to avoid creating any unnecessary dependencies. New dependency to the project is subjected to a lead developer's review and approval.
Many of Appwrite's internal modules are also used as dependencies to allow other Appwrite projects to reuse them and as a way to contribute back to the community.
Appwrite uses PHP's Composer for managing dependencies on the server-side and JS NPM for managing dependencies on the frontend side.
Appwrite follows the PHP-FIG standards. Currently, we use both PSR-0 and PSR-12 for coding standards and autoloading standards.
We use prettier for our JS coding standards and auto-formatting for our code.
Appwrite is built to scale. Please keep in mind that the Appwrite stack can run in different environments and different scales.
We intend Appwrite to be as easy to set up as possible in a single localhost, and to grow easily into a large environment with dozens and even hundreds of instances.
When contributing code, please take into account the following:
- Response Time
- Throughput
- Requests per Seconds
- Network Usage
- Memory Usage
- Browser Rendering
- Background Jobs
- Task Execution Time
Security and privacy are extremely important to Appwrite, developers, and users alike. Make sure to follow the best industry standards and practices.
Please avoid introducing new dependencies to Appwrite without consulting the team. New dependencies can be very helpful, but they also introduce new security and privacy risks, add complexity, and impact the total docker image size.
Adding a new dependency should have vital value for the product with minimum possible risk.
We would 💖 you to contribute to Appwrite, but we also want to ensure Appwrite is loyal to its vision and mission statement 🙏.
For us to find the right balance, please open an issue explaining your ideas before introducing a new pull request.
This will allow the Appwrite community to sufficiently discuss the new feature value and how it fits within the product roadmap and vision.
This is also important for the Appwrite lead developers to be able to provide technical input and potentially a different emphasis regarding the feature design and architecture. Some bigger features might need to go through our RFC process.
To build a new version of the Appwrite server, all you need to do is run the build.sh file like this:
bash ./build.sh X.X.XBefore running the command, make sure you have proper write permissions to the Appwrite docker hub team.
Build for Multicore
docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v6,linux/arm/v7,linux/arm64/v8,linux/ppc64le,linux/s390x -t appwrite/appwrite:dev --push .Build Functions Runtimes
The Runtimes for all supported cloud functions (multicore builds) can be found at the open-runtimes/open-runtimes repository.
The following steps are used to generate a new console SDK:
- Update the console spec file located at
app/config/specs/swagger2-<version-number>.console.jsonusing Appwrite Tasks. Run thephp app/cli.php specs version=<version-number> mode=normalcommand in a runningappwrite/appwritecontainer. - Generate a new SDK using the command
php app/cli.php sdks. - Change your working dir using
cd app/sdks/console-web. - Build the new SDK
npm run build. - Copy
iife/sdk.jstoappwrite.js. - Go back to the root of the project
run npm run build.
Things to remember when releasing SDKs:
- Update the Changelogs in docs/sdks (right now only Dart and Flutter are using these).
- Update GETTING_STARTED.md in docs/sdks for each SDKs if any changes in the related APIs are in there.
- Update SDK versions as required on app/config/platforms.php.
- Generate SDKs using the command
php app/cli.php sdksand follow the instructions. - Release new tags on GitHub repository for each SDK.
Appwrite uses yasd debugger, which can be made available during build of Appwrite. You can connect to the debugger using VS Code's PHP Debug extension.
If you are in PHP Storm you don't need any plugin. Below are the settings required for remote debugger connection:
- Create an init file.
- Duplicate dev/yasd_init.php.stub file and name it dev/yasd_init.php.
- Set DEBUG build arg in appwrite service in docker-compose.yml file.
{
"name": "Listen for Xdebug",
"type": "php",
"request": "launch",
"port": 9005,
"pathMappings": {
"/usr/src/code": "${workspaceRoot}"
}
}In settings, go to Languages & Frameworks > PHP > Debug, under Xdebug set the debug port to 9005 and enable the can accept external connections checkbox.
To run all tests manually, use the Appwrite Docker CLI from your terminal:
docker compose exec appwrite testTo run unit tests use:
docker compose exec appwrite test /usr/src/code/tests/unitTo run end-2-end tests use:
docker compose exec appwrite test /usr/src/code/tests/e2eTo run end-2-end tests for a specific service use:
docker compose exec appwrite test /usr/src/code/tests/e2e/Services/[ServiceName]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.
Options:
-c, --connections <N> Connections to keep open
-d, --duration <T> Duration of test
-t, --threads <N> Number of threads to use
-s, --script <S> Load Lua script file
-H, --header <H> Add header to request
--latency Print latency statistics
--timeout <T> Socket/request timeout
-v, --version Print version details
docker run --rm skandyla/wrk -t3 -c100 -d30 https://[APPWRITE_HOSTNAME_OR_IP]We use some automation tools to help us keep a healthy codebase.
