How to Install FastApi in 3 Minutes

If you’re looking to quickly install FastApi, a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints, this article will guide you through the process in just 3 minutes.

Step 1: Create a Virtual Environment

Open your terminal or command prompt and navigate to the directory where you want to create your project. Run the following command to create a virtual environment:

    
      $ python3 -m venv myenv
    
  

Step 2: Activate the Virtual Environment

Next, activate the virtual environment using the following command:

    
      $ source myenv/bin/activate
    
  

Step 3: Install FastApi

Now that your virtual environment is active, you can easily install FastApi using pip:

    
      $ pip install fastapi
    
  

Step 4: Verify the Installation

To verify that FastApi is installed correctly, you can run the following command to check the version:

    
      $ python -m fastapi --version
    
  

Step 5: Create Your First FastApi Application

Now that you have FastApi installed, you can start building your API. Create a new Python file, for example, main.py, and write your FastApi application code. Here’s a simple example to get you started:

    
      from fastapi import FastAPI

      app = FastAPI()

      @app.get("/")
      def read_root():
          return {"Hello": "World"}
    
  

Save the file and run it using the following command:

    
      $ uvicorn main:app --reload
    
  

Now you have successfully installed FastApi and created your first FastApi application in just 3 minutes!

Conclusion

Installing FastApi is quick and easy, and with the simple example provided, you can start building powerful APIs with Python in no time. Happy coding!
