connect-base

Get the base url for Express/Connect apps

Use

Set up a server that echoes the requesting url:

var app = connect();
    base = require("connect-base");

app.use(base());

app.use(function(req, res){
  res.send(req.base);
})

When we request it locally:

curl http://localhost:5000
> http://localhost:5000

When we host it through a DNS server:

curl http://example.com
> http://example.com

We can also set the protocol, host, port, and path; maybe through a reverse proxy

curl -H "X-Forwarded-Proto: https" http://example.com
> https://example.com

curl -H "X-Forwarded-Host: test.example.com" http://example.com
> http://test.example.com

curl -H "X-Forwarded-Port: 8080" http://example.com
> http://example.com:8080

curl -H "X-Forwarded-Path: /testing" http://example.com
> http://example.com/testing

Testing

npm install -d
npm test
