Gelatin Python Web Framework built for learning purposes.
Project description
Gelatin: Python Web Framework built for learning purposes
Gelatin is a WSGI framework and can be used with any WSGI application server such as Gunicorn.
Installation
pip install gelatin_mattymar
How to use it
Basic usage:
from jello.api import API
app = API()
@app.route('/home')
def home(request, response):
response.text = 'Hello from the HOME page'
@app.route('/users/{name}')
def greeting(request, response, name):
response.text = f'Hello there, {name}'
# Class-based handler
@app.route('/book')
class BooksResource:
def get(self, req, resp):
resp.text = 'Books Page'
def post(self, req, resp):
resp.text = 'Endpoint to create a book'
# Template handler
def template_handler(req, resp):
resp.body = app.template(
'index.html', context={"name": "Jello", "title": "Awesome framework"}
).encode()
Unit Tests
The recommended way of writing unit tests is with pytest. There are two built in fixtures
that you may want to use when writing unit tests with Bumbo. The first one is app which is an instance of the main API class:
def test_route_overlap_throws_exception(app):
@app.route("/")
def home(req, resp):
resp.text = "Welcome Home."
with pytest.raises(AssertionError):
@app.route("/")
def home2(req, resp):
resp.text = "Welcome Home2."
The other one is client that you can use to send HTTP requests to your handlers. It is based on the famous requests and it should feel very familiar:
def test_parameterized_route(app, client):
@app.route("/{name}")
def hello(req, resp, name):
resp.text = f"hey {name}"
assert client.get("http://testserver/matthew").text == "hey matthew"
Templates
The default folder for templates is templates. You can change it when initializing the main API() class:
app = API(templates_dir="templates_dir_name")
Then you can use HTML files in that folder like so in a handler:
@app.route("/show/template")
def handler_with_template(req, resp):
resp.html = app.template(
"example.html", context={"title": "Awesome Framework", "body": "welcome to the future!"})
Static Files
Just like templates, the default folder for static files is static and you can override it:
app = API(static_dir="static_dir_name")
Then you can use the files inside this folder in HTML files:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{title}}</title>
<link href="/static/main.css" rel="stylesheet" type="text/css">
</head>
<body>
<h1>{{body}}</h1>
<p>This is a paragraph</p>
</body>
</html>
Middleware
You can create custom middleware classes by inheriting from the bumbo.middleware.Middleware class and overriding its two methods
that are called before and after each request:
from bumbo.api import API
from bumbo.middleware import Middleware
app = API()
class SimpleCustomMiddleware(Middleware):
def process_request(self, req):
print("Before dispatch", req.url)
def process_response(self, req, res):
print("After dispatch", req.url)
app.add_middleware(SimpleCustomMiddleware)
