## What is it and what is it for
[Fastipy](https://pypi.org/project/Fastipy/) is a fast and easy-to-use open source Python library for developing RESTful APIs.
Powered by **[uvicorn](https://www.uvicorn.org/)**
## Installation
```bash
pip install fastipy
```
## Examples
### Example for GET Route with Query Params
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
# Routes can be async or sync functions, but reply send functions are async
# The handler returns the default HTTP status code 200
@app.get("/")
def home(req: Request, _):
# Get query params age
age = req.query["age"]
# Example: Recovery all persons from database with this age and print the html
print("<h1>Retrieving all persons</h1><ul><li>A Person</li></ul>")
```
### Example for GET Route with Params, CORS and multiple methods
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy().cors()
@app.get("/user/:id")
@app.post("/user/:id")
async def getUser(req: Request, reply: Reply):
# get users from database
for i in users:
if i["id"] == req.params["id"]:
# All response functions are asynchronous
return await reply.send(i)
await reply.send_code(404)
```
### Example for POST Route with Body
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
@app.post("/user")
async def createUser(req: Request, reply: Reply):
user = req.body.json
# Save user in database
await reply.code(201).send("Created")
```
### Example for PUT Route with Body
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
@app.put("/user")
async def createUser(req: Request, reply: Reply):
user = req.body.json
# Update user in database
await reply.type("text/html").code(201).send("<h1>Created</h1>")
```
### Example for GET Route with file stream
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
@app.get("/stream")
async def streamFile(_, reply: Reply):
# It could be an asynchronous generator
def generator():
with open("file.txt") as f:
for line in f:
yield line
await reply.send(generator())
```
### Adding custom serializer to Reply send
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
app.add_serializer(
validation=lambda data: isinstance(data, str),
serializer=lambda data: ("application/json", json.dumps({"error": data})),
)
@app.get("/")
async def customSerializer(_, reply: Reply):
await reply.code(404).send("Field not found")
```
### Running
Running Fastipy application in development is easy
```py
import uvicorn
if __name__ == "__main__":
# main:app indicates the FILE:VARIABLE
# The file is the main file where Fastipy() is instantiated
# The variable is the name of the variable that contains the instance of Fastipy()
# You can find more configurations here https://www.uvicorn.org/
# set reload to True for automatic reloading!
uvicorn.run("main:app", log_level="debug", port=8000, reload=True, loop="asyncio")
```
### See more examples in **[examples](https://github.com/Bielgomes/Fastipy/tree/main/examples)** folder
## Creating plugins
```py
# chat.py
from fastipy import FastipyInstance, Reply
# Plugins can be asynchronous or synchronized functions
# Plugins have access to the main instance, which means they can use all of Fastipy's functions
def chatRoutes(app: FastipyInstance, options: dict):
@app.get("/")
async def index(_, reply: Reply):
await reply.send_code(200)
@app.get("/chat")
async def test(_, reply: Reply):
await reply.send_code(200)
```
```py
# message.py
from fastipy import FastipyInstance, Reply
async def messageRoutes(app: FastipyInstance, options: dict):
@message.get("/")
async def index(_, reply: Reply):
await reply.send_code(200)
@message.get("/message")
async def test(_, reply: Reply):
await reply.send_code(200)
app.name("custom plugin name")
```
```py
# main.py
from fastipy import Fastipy
from message import messageRoutes
from chat import chatRoutes
app = Fastipy().cors()
app.register(messageRoutes, {"prefix": "/message"})
app.register(chatRoutes, {"prefix": "/chat"})
```
## Hooks
```py
from fastipy import Fastipy, Request, Reply
app = Fastipy()
# The preHandler hook is called before the request handler
@app.hook("preHandler")
def preHandler(req: Request, reply: Reply):
print("onRequest hook")
# The onRequest hook is called when the request is handled
@app.hook("onRequest")
def onRequest(req: Request, reply: Reply):
print("onRequest hook")
# The onResponse hook is called when the reply sends a response
@app.hook("onResponse")
def onResponse(req: Request, reply: Reply):
print("onResponse hook")
# The onError hook is called when an error occurs
@app.hook("onError")
def onError(error: Exception, req: Request, reply: Reply):
print(f"onError hook exception: {error}")
# A hook will only be linked to a route if its declaration precedes the route
# The order of hooks of the same type is important
@app.get("/")
async def index(_, reply: Reply):
await reply.send_code(200)
```
## End to End tests
```py
# See more in https://www.starlette.io/testclient/
from fastipy import TestClient
from main import app
client = TestClient(app)
response = client.post("/")
assert response.status_code == 200
assert response.text == "Hello World"
```
# Application Deploy
For production deployment, please refer to this **[uvicorn guide](https://www.uvicorn.org/deployment/)**.
# Change Log
## Development Version 1.5.4
### Todo
### Added
### Changed
- [X] Change the routes handler to use the Raw Path instead of the Path (This Change allow the use of %20 %2F and other special characters in the path)
- [X] Improve functionality to handle asynchronous functions in synchronous environments (This change probably fix Memory Leak in the Fastipy)
