nodejs_http_servers

A NodeJS sample to show how a server makes a HTTP request to another server

Usage

To run a sample of how this works:

• Run npm install
• Run both servers by typing these on the command line: node index.js (port 3000) and node otherServer.js (port 3001)
• On the server with port 3000, you can make a HTTP request by typing this URL on the browser

http://localhost:3000/route/userId/123/name/guesswho

• On the same server with port 3000, you can also call this endpoint. The other server (having port 3001)--after receiving the request--will do a redirect to itself with a new endpoint before sending back the response to the calling server. Moreover, the HTTP connection for this will be persistent (with keep-alive and connection pooling).

http://localhost:3000/redirectRoute/userId/123/name/guesswho

• If you look at the console, you will see that the request is routed to the other server--which in turn also sends a response back to the calling server (that initially made the request)
• As an alternative, you can also install wrk and make multiple requests to the server. This command line tool is useful for a more detailed benchmarking when making requests.

wrk -t1 -c1 -d1s http://localhost:3000/redirectRoute/userId/123/name/guesswho

Dependencies

The servers uses Express and Request NodeJS modules
