With hypha, you can register a service which serves an ASGI application, e.g. a FastAPI app which serve a web page, or a web API. +## Introduction -The following example shows how to use FastAPI to create a web application in the browser, e.g. https://imjoy-notebook.netlify.app/, and serve it through Hypha. +When deploying ASGI web applications like those built with FastAPI, developers often rely on traditional servers and tools like **Uvicorn**. Uvicorn is a popular choice for serving ASGI applications due to its simplicity and ease of use. Typically, you can start a server with the following command: -You need to first install fastapi: +```bash +uvicorn myapp:app --host 0.0.0.0 --port 8000 +``` + +However, this approach has limitations, particularly when you need to expose your application to the public. Hosting a server with Uvicorn typically requires: +- A public IP address. +- DNS management. +- SSL certificates for secure connections. +- Firewall configurations to ensure access while maintaining security. + +For many users, especially those working in environments with restrictive networks or behind firewalls, exposing a server publicly can be cumbersome and insecure. Moreover, maintaining server infrastructure and ensuring security compliance adds significant overhead. + +**Hypha** provides a solution to these challenges by allowing you to serve ASGI applications without the need for traditional server setups. With Hypha, you can instantly deploy and make your web application publicly accessible, bypassing the need for public IP addresses, DNS, or server management. This is especially beneficial in scenarios where you want to quickly share your application without worrying about the complexities of infrastructure. + +## The Hypha Serve Utility + +To streamline the process of deploying ASGI applications, Hypha offers a utility similar to Uvicorn, but with added benefits. The `hypha_rpc.utils.serve` utility allows you to serve your FastAPI (or any ASGI-compatible) application directly through the Hypha platform. This tool provides a simple command-line interface that makes deployment quick and easy. + +### Why Use Hypha Over Uvicorn? + +While Uvicorn is a powerful tool for local development and serving applications within controlled environments, Hypha's serve utility offers: +- **Ease of Access**: No need for public IP, DNS management, or SSL certificates. +- **Security**: Hypha handles secure connections and access control. +- **Simplicity**: Deploy your application with a single command, without worrying about infrastructure management. +- **Flexibility**: For advanced use cases, Hypha allows direct registration of ASGI services, giving you fine-grained control. + +### Serving Your ASGI App with Hypha + +Let's explore how to use the `hypha_rpc.utils.serve` utility to deploy your FastAPI application. + +## Prerequisites + +- **Hypha**: Ensure you have Hypha installed and configured. +- **FastAPI**: For this example, we'll use FastAPI, but any ASGI-compatible framework will work. +- **Python 3.9+**: The utility requires Python 3.9 or higher. + +## Installation -In Pyodide, you can install it using micropip: +If you haven't installed FastAPI yet, you can do so using pip: + +```bash +pip install fastapi +``` + +Ensure that `hypha_rpc` is installed and available in your environment. + +## Usage + +### Basic Example + +Here’s a simple example of how to serve a FastAPI application using the `hypha_rpc.utils.serve` utility. + +### Step 1: Create a FastAPI App + +Create a simple FastAPI app (e.g., `myapp.py`): ```python -import micropip -await micropip.install(["fastapi==0.70.0"]) +from fastapi import FastAPI +from fastapi.responses import HTMLResponse + +app = FastAPI() + +@app.get("/", response_class=HTMLResponse) +async def root(): + return """ + + Cat + cat + + """ + +@app.get("/api/v1/test") +async def test(): + return {"message": "Hello, it works!"} +``` + +### Step 2: Serve the App Using the Hypha Serve Utility + +You can serve your ASGI app with Hypha using the following command: + +```bash +python -m hypha_rpc.utils.serve myapp:app --id=cat --name=Cat --server-url=https://hypha.aicell.io --workspace=my-workspace --token=your_token_here +``` + +### Parameters + +- `myapp:app`: The `module:app` format where `myapp` is your Python file, and `app` is the FastAPI instance. +- `--id`: A unique identifier for your service. +- `--name`: A friendly name for your service. +- `--server-url`: The URL of the Hypha server. +- `--workspace`: The workspace you want to connect to within the Hypha server. +- `--token`: The authentication token for accessing the Hypha server. + +### Using the `--login` Option + +If you don’t have a token or prefer to log in interactively, you can use the `--login` option: + +```bash +python -m hypha_rpc.utils.serve myapp:app --id=cat --name=Cat --server-url=https://hypha.aicell.io --workspace=my-workspace --login ``` -Or in normal Python, you can install it using pip: +This will prompt you to log in, and it will automatically retrieve and use the token. + +### Disabling SSL Verification + +If you need to disable SSL verification (e.g., for testing purposes), you can use the `--disable-ssl` option: ```bash -pip install -U fastapi +python -m hypha_rpc.utils.serve myapp:app --id=cat --name=Cat --server-url=https://hypha.aicell.io --workspace=my-workspace --login --disable-ssl ``` -Then you can create a FastAPI app and serve it through Hypha: +### Accessing the Application + +Once the app is running, you will see a URL printed in the console, which you can use to access your app. The URL will look something like this: + +``` +https://hypha.aicell.io/{workspace}/apps/{service_id} +``` + +Replace `{workspace}` and `{service_id}` with the actual workspace name and service ID you provided. + +### Example Commands + +**Serve with Token:** + +```bash +python -m hypha_rpc.utils.serve myapp:app --id=cat --name=Cat --server-url=https://hypha.aicell.io --workspace=my-workspace --token=sflsflsdlfslfwei32r90jw +``` + +**Serve with Login and Disable SSL:** + +```bash +python -m hypha_rpc.utils.serve myapp:app --id=cat --name=Cat --server-url=https://hypha.aicell.io --workspace=my-workspace --login --disable-ssl +``` + +## Advanced: Registering the ASGI Service Directly + +For users who prefer more flexibility and control, Hypha also allows you to register the ASGI service directly through the platform, bypassing the utility function.

By removing the need for traditional server setups, Hypha enables you to focus on your application without the overhead of managing infrastructure. Whether you’re deploying in a local environment or directly in a browser, Hypha simplifies the process, making it easier than ever to share your ASGI apps with the world. The added flexibility of direct service registration and browser-based FastAPI apps expands the possibilities for deploying and sharing your web applications. diff --git a/docs/getting-started.md b/docs/getting-started.md index 5664b9a3..810b9539 100644 --- a/docs/getting-started.md +++ b/docs/getting-started.md @@ -220,7 +220,7 @@ svc = await get_remote_service("http://localhost:9527/ws-user-scintillating-lawy Include the following script in your HTML file to load the `hypha-rpc` client: ```html - + ``` Use the following code in JavaScript to connect to the server and access an existing service: @@ -516,26 +516,3 @@ Multiple startup functions can be specified by providing additional `--startup-f python -m hypha.server --host=0.0.0.0 --port=9527 --startup-functions=./example-startup-function.py:hypha_startup ./example-startup-function2.py:hypha_startup ``` -#### Launching External Services Using Commands - -If you need to start services written in languages other than Python or requiring a different Python environment than your Hypha server, you can use the `launch_external_services` utility function available in the `hypha.utils` module. - -Here's an example of using `launch_external_services` within a startup function initiated with the `--startup-functions` option: - -```python -from hypha.utils import launch_external_services - -async def hypha_startup(server): - # ... - - await launch_external_services( - server, - "python ./tests/example_service_script.py --server-url={server_url} --service-id=external-test-service --workspace={workspace} --token={token}", - name="example_service_script", - check_services=["external-test-service"], - ) -``` - -In this example, `launch_external_services` starts an external service defined in `./tests/example_service_script.py`.
