HTTP-Server

This is a HTTP Server built using NodeJs's .net library. I built this server from scratch to understand the inner-workings of HTTP such as dynamic buffers, TCP connections and URI's.

Building the Server

First, clone the repository using git clone: git clone https://github.com/NateMartes/HTTP-Server.git

Then there are two approaches provided for building the server:

1. Using Docker (Docker Documentation)

Using Docker, build the Docker image using the provided Dockerfile (assuming in your the current repository):

sudo docker build -t http-server:latest .

Then run the container using:

sudo docker run -dp {host-port}:1234 --name http_server http-server:latest

2. Using NodeJS (NodeJS Documentation)

Assuming you have NodeJS install, you can run:

npx tsx httpServer.ts

NOTE: The Server using port 1234 by default. you can change this by altering the used port in httpServer.ts

Testing the Server

Testing the server can be done using curl:

curl http://0.0.0.0:1234

which returns Hello World!.

Also the URI /echo returns the payload the client sends to the server

curl --data-binary @/some/data/file http://0.0.0.0:1234/echo
