Nebula is a lightweight Python backend framework with middleware and routing, built on top of the werkzeug module. It allows you to create web applications quickly with simple, decorator-based routing.

Features

• Decorator-based Routing: Define your routes with simple and intuitive decorators.
• Template Loading: Easily load and serve HTML templates from a designated directory.
• Statics Loading: Easily load and serve files from designated directory.
• Middleware Support: before_request and after_request hooks for flexible request handling.
• Easy to Use: Get a server up and running in just a few lines of code.

Installation

Install Nebula from PyPI:

pip install nebula-core

or clone and install from GitHub.

git clone https://github.com/VxidDev/nebula.git
cd nebula
pip install .

Usage

Here's a basic example of creating a simple web server with Nebula.

main.py:

from nebula import Nebula , Response

from nebula.utils import (
    jsonify, htmlify, init_static_serving , load_template , render_template , init_template_renderer , render_template_string,
    init_template_path
)

app = Nebula(__file__ , "localhost", 8000, False)

init_static_serving(app, "statics")
init_template_path(app)
init_template_renderer(app)

jinja_template = """
    <h1>{{ APP.host + ":" + APP.port|string }}</h1>
"""

@app.route("/" , methods=["GET" , "POST"])
def main(request):
    if request.method == "POST":    
        data = request.get_json()

        return jsonify({"greet": f"Hi, {data.get('name', 'default')}!"})

    return render_template(app, "test.html")

@app.route("/greet/<name>")
def greet(request, name):
    return htmlify(f"<h1>Hi, {name}!</h1>")

@app.route("/fruits")
def jsonTest(request):
    return jsonify({
        "fruits": {
            "apples": 6,
            "pears": 10,
            "mangos": 9
        } 
    })

@app.error_handler(405)
def method_not_allowed(request):
    return htmlify("<h1>Cant do that :[</h1>", 405)

@app.error_handler(404)
def not_found(request):
    return htmlify("<h1>Cant find that :(</h1>", 404)

@app.error_handler(500)
def doesnt_work(request):
    return htmlify("<h1>Internal Error!</h1>", 500)

@app.route("/internal-error")
def error(request):
    return Response(f"Error!", 500)

@app.route("/api", methods=["POST"])
def api(request):
    return jsonify({"a": 1, "b": 2, "c": 3}[request.get_json().get("item", "a")])

@app.route("/jinja")
def jinja(request):
    return render_template(app, "jinja_template.html", APP=app)

@app.route("/jinja/string")
def jinja_string(request):
    return htmlify(render_template_string(app, jinja_template, APP=app))

app.run()
