If you're a Python developer looking for a simple yet powerful web framework, Nev is a great option to try out. Nev is a lightweight framework designed to be simple and easy to use, while still providing powerful features for building web applications.
Nev is built on top of the Flask micro-framework and provides a number of extensions to make building web applications easier. Some of the features provided by Nev include:
To get started with Nev, you can install it using pip:
pip install nev
Once you have Nev installed, you can start building your first web application. Here's an example application that displays a "Hello World" message:
from nev import Nev
app = Nev(__name__)
@app.route("/")
def home():
return "Hello World!"
if __name__ == "__main__":
app.run()
This code creates a new Nev application and defines a single route for the root URL ("/"). When a user visits this URL, the home() function is called and returns a "Hello World!" message.
Of course, most web applications require more than just plain text responses. You'll likely want to build HTML templates to display information to users. Nev integrates with the Jinja2 templating engine to make building templates easy.
Here's an example template:
<!DOCTYPE html>
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h1>{{ message }}</h1>
</body>
</html>
And here's how you can use the template with Nev:
from nev import Nev, render_template
app = Nev(__name__)
@app.route("/")
def home():
return render_template("home.html", title="Home", message="Welcome to my site!")
if __name__ == "__main__":
app.run()
This code defines a home() function that returns a rendered template using the render_template() function. The function takes the name of the template ("home.html") and any variables that should be passed to the template ("title" and "message").
Nev is a great option for Python developers who want a lightweight and easy-to-use web framework. With its simple routing, Jinja2 templating engine, and support for popular Python libraries, Nev makes building web applications quick and painless.
