ClearFlask is a micro-framework that is fast, simple, and lightweight, making it suitable for building small to medium-sized web applications. This tutorial will guide you through the installation process of ClearFlask on your Elementary OS.
Before installing ClearFlask, you need to make sure that your system has the following prerequisites:
To check if you have Python correctly installed, run the following command in your terminal:
python3 --version
This should display the version of Python installed on your system. If Python is not installed, you can install it by running the following command:
sudo apt update
sudo apt install python3
To install the pip package installer, run the following command:
sudo apt-get install python3-pip
Once you have these prerequisites installed, you can proceed with the installation of ClearFlask.
Follow the steps below to install ClearFlask:
Step 1: Open your terminal and create a directory for your project:
mkdir my-clearflask-project
cd my-clearflask-project
Step 2: Create a virtual environment for your project:
python3 -m venv venv
Step 3: Activate the virtual environment:
source venv/bin/activate
Step 4: Use pip to install ClearFlask in your virtual environment:
pip install clearflask
And that's it! ClearFlask is now installed in your virtual environment and ready to use.
To create a ClearFlask project, follow these steps:
Step 1: Navigate to your project directory and activate your virtual environment:
cd my-clearflask-project
source venv/bin/activate
Step 2: Create a Python file called app.py:
touch app.py
Step 3: Open app.py in your text editor and add the following contents:
from clearflask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return 'Hello, World!'
if __name__ == '__main__':
app.run()
This code creates a Flask application that listens for requests on the root URL (/). When a request is received, the home function returns the string 'Hello, World!'. The if __name__ == '__main__' block ensures that the app only runs when the script is executed directly (as opposed to being imported as a module).
Step 4: Save your changes to app.py.
Step 5: Start the development server:
python app.py
You should see output indicating that the server is running on http://localhost:5000. Opening a web browser and navigating to http://localhost:5000 should display the 'Hello, World!' message.
You now have a basic ClearFlask app up and running on your Elementary OS. You can start building your app by adding more routes, views, and functionality to it. Happy coding!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
