HTTP Streaming with FastAPI and JS

Installation

pip install -r requirements.txt

Run the server

uvicorn api:app 

There are two endpoints,

• /file -> send a file
• /stream -> creates server sent events

Then, run the client (install node)

node main.ts

Have a look inside, there are two functions fetch_stream and fetch_file_stream the first one consumes the server sent event and the second the file - both are HTTP streaming requests resulting in a ReadableStream class
