How to Install Flask in Visual Studio Code with Sample API Example
Flask is a lightweight and powerful web framework for Python, perfect for building web applications and APIs with ease. Integrating Flask into Visual Studio Code (VS Code) provides a seamless development experience for creating Python-based web projects. In this tutorial, we'll walk you through the step-by-step process of installing Flask in Visual Studio Code and demonstrate how to create a sample API using Flask, enabling you to kickstart your web development journey with confidence.
**Step 1: Install Python and Visual Studio Code:**
1. If you haven't already, download and install Python from the official Python website (https://www.python.org/).
2. Similarly, download and install Visual Studio Code (https://code.visualstudio.com/) on your computer.
**Step 2: Create a New Folder for Your Flask Project:**
1. Open Visual Studio Code.
2. Create a new folder for your Flask project using the File Explorer sidebar in VS Code.
**Step 3: Open a New Terminal in Visual Studio Code:**
1. Open a new terminal in Visual Studio Code by selecting Terminal - New Terminal from the menu.
**Step 4: Create a Virtual Environment (Optional but Recommended):**
1. In the terminal, navigate to your project folder.
2. Create a virtual environment by running:
```
python -m venv venv
```
3. Activate the virtual environment:
- On Windows:
```
.\venv\Scripts\activate
```
- On macOS/Linux:
```
source venv/bin/activate
```
**Step 5: Install Flask:**
1. With the virtual environment activated, install Flask using pip:
```
pip install Flask
```
**Step 6: Create a Sample Flask App:**
1. Create a new Python file (e.g., `app.py`) in your project folder.
2. Open `app.py` in Visual Studio Code.
3. Write a simple Flask application, such as:
```python
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello, World!'
if __name__ == '__main__':
app.run(debug=True)
```
**Step 7: Run the Flask App:**
1. In the terminal, navigate to your project folder.
2. Run the Flask application by executing:
```
python app.py
```
**Step 8: Test the API:**
1. Open a web browser and navigate to `http://localhost:5000/`.
2. You should see the message "Hello, World!" displayed in the browser.
Congratulations! You have successfully installed Flask in Visual Studio Code and created a sample API using Flask. You can now explore further and develop more complex web applications and APIs using Flask within the VS Code environment.
