Original README

---

This is a starting point for TypeScript solutions to the "Build Your Own HTTP server" Challenge.

HTTP is the protocol that powers the web. In this challenge, you'll build a HTTP/1.1 server that is capable of serving multiple clients.

Along the way you'll learn about TCP servers, HTTP request syntax, and more.

Note: If you're viewing this repo on GitHub, head over to codecrafters.io to try the challenge.

Passing the first stage

The entry point for your HTTP server implementation is in app/main.ts. Study and uncomment the relevant code, and push your changes to pass the first stage:

git commit -am "pass 1st stage" # any msg
git push origin master

Time to move on to the next stage!

Stage 2 & beyond

Note: This section is for stages 2 and beyond.

1. Ensure you have bun (1.2) installed locally
2. Run ./your_program.sh to run your program, which is implemented in app/main.ts.
3. Commit your changes and run git push origin master to submit your solution to CodeCrafters. Test output will be streamed to your terminal.
