What is FastAPI?
Before we dive into the details of how FastAPI helps in faster downloads, let’s understand what it is. FastAPI is a new entrant in the Python web framework arena that aims to provide high performance while keeping the API specification simple.
Downloading Files with FastAPI
Now let’s move on to our main topic, downloading large files using FastAPI. Below are the steps you need to follow:
Step 1: Install Required Packages
FastAPI depends upon Starlette for web responses, and you will need the aiofiles library for efficient file handling. Install them using pip command:
|FastAPI||pip install fastapi|
|Starlette||pip install starlette|
|aiofiles||pip install aiofiles|
Step 2: Create a FastAPI application
Create a new Python file and add the following code:
Step 3: Define the File Path and Name
Now that you have set up the API application, you need to define the path and name of the file to download. This is how you do it:
Step 4: Stream the File
Instead of downloading the whole file in one go, stream it. This way, you can start downloading immediately without waiting for the whole file to be loaded. Here’s how:
Step 5: Start the FastAPI Application
Now run the FastAPI application using the command below:
Comparison with Other Methods
FastAPI is a relatively new framework, and there are other methods we could use to download large files efficiently. Two other ways are
Method 1: Using PycURL
Method 2: Using Wget Command-Line Tool
FastAPI allows you to download large files more efficiently and at a faster pace. In this article, we went through a step-by-step guide on how to do so. We also compared FastAPI’s method with other methods like PycURL and Wget tool. Overall, FastAPI provides a simple and smooth solution to efficiently download large files.

Here are some common questions people ask about Efficiently Download Large Files with FastAPI: A Step-By-Step Guide and their answers:
What is FastAPI?
FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints.
How can I efficiently download large files with FastAPI?
You can use the
StreamingResponseclass in FastAPI to download large files efficiently. This class allows you to stream the file in chunks rather than loading the entire file into memory at once, which can cause performance issues.
Can I download multiple files at once with FastAPI?
Yes, you can use the
ZipFileclass from the Python standard library to create a zip archive of multiple files, and then use the
StreamingResponseclass to stream the zip archive to the client.
Is FastAPI suitable for large-scale projects?
Yes, FastAPI is designed to be scalable and performant. It uses modern Python features like async/await and type hints to provide fast and efficient request handling. Additionally, it integrates well with other Python libraries and tools, making it a good choice for large-scale projects.
How does FastAPI compare to other Python web frameworks?
FastAPI is faster and more performant than many other Python web frameworks like Flask and Django. It also has built-in support for async/await, which can improve performance for I/O-bound tasks. Additionally, FastAPI has a modern API documentation system that automatically generates documentation based on your code.
