Robyn is a High-Performance, Community-Driven, and Innovator Friendly Web Framework with a Rust runtime. You can learn more by checking our [community resources](https://sansyrox.github.io/robyn/#/community-resources)!
## 📦 Installation
You can simply use Pip for installation.
```
pip install robyn
```
Or, with [conda-forge](https://conda-forge.org/)
```
conda install -c conda-forge robyn
```
## 🤔 Usage
### 🚀 Define your API
To define your API, you can add the following code in an `app.py` file.
```python
from robyn import Robyn
app = Robyn(__file__)
@app.get("/")
async def h(request):
return "Hello, world!"
app.start(port=8080)
```
### 🏃 Run your code
Simply run the app.py file you created. You will then have access to a server on the `localhost:8080`, that you can request from an other program. Robyn provides several options to customize your web server.
```
$ python3 app.py
```
To see the usage
```
usage: app.py [-h] [--processes PROCESSES] [--workers WORKERS] [--dev] [--log-level LOG_LEVEL]
Robyn, a fast async web framework with a rust runtime.
options:
-h, --help show this help message and exit
--processes PROCESSES Choose the number of processes. [Default: 1]
--workers WORKERS Choose the number of workers. [Default: 1]
--dev Development mode. It restarts the server based on file changes.
--log-level LOG_LEVEL Set the log level name
--create Create a new project template.
--docs Open the Robyn documentation.
--open-browser Open the browser on successful start.
```
Log level can be `DEBUG`, `INFO`, `WARNING`, or `ERROR`.
When running the app using `--open-browser` a new browser window will open at the app location, e.g:
```
$ python3 app.py --open-browser
```
### 💻 Add more routes
You can add more routes to your API. Check out the routes in [this file](https://github.com/sansyrox/robyn/blob/main/integration_tests/base_routes.py) as examples.

## 🗒️ How to contribute
### 🏁 Get started
Please read the [code of conduct](https://github.com/sansyrox/robyn/blob/main/CODE_OF_CONDUCT.md) and go through [CONTRIBUTING.md](https://github.com/sansyrox/robyn/blob/main/CONTRIBUTING.md) before contributing to Robyn.
Feel free to open an issue for any clarifications or suggestions.
If you're feeling curious. You can take a look at a more detailed architecture [here](https://sansyrox.github.io/robyn/#/architecture).
If you still need help to get started, feel free to reach out on our [community discord](https://discord.gg/rkERZ5eNU8).
### ⚙️ To Develop Locally
1. Install the development dependencies: `poetry install --with dev --with test`
2. Install the pre-commit git hooks: `pre-commit install`
3. Run `maturin develop` or `maturin develop --cargo-extra-args="--features=io-uring"` for using the experimental version of actix-web. This command will build the Robyn Rust package and install it in your virtual environment.
4. Run `poetry run test_server`. This will run a server containing several examples of routes we use for testing purposes. You can see them at `integration_tests/base_routes.py`. You can modify or add some to your likings.
You can then request the server you ran from an other terminal. Here is a `GET` request done using [curl](https://curl.se/) for example:
```bash
curl http://localhost:8080/sync/str
```
