Request for more documentation + question on why /api is being stripped off.

[adamzerner]

I'd find more documentation useful. I like that common scenarios are covered with good examples, but I don't see how to branch out from there.

For example, I'm trying to route everything prefaced with /api to localhost:3001, and everything else to localhost:3002 but can't figure out how to do so.

When I do this:

var express = require('express');
var proxyServer = require('http-route-proxy');
var app = express();

app.use('/api', proxyServer.connect({
  from: 'localhost:3000',
  to: 'localhost:3001', // api server
  https: false,
  route: ['/']
}));

app.use(proxyServer.connect({
  from: 'localhost:3000',
  to: 'localhost:3002', // web server
  https: false,
  route: ['/']
}));

app.listen(3000, function() {
  console.log('Proxy listening on port 3000...');
});

The /api part gets stripped off somehow:

forward GET  /auth/facebook from localhost:3000 to http://localhost:3001/auth/facebook

The /api part gets stripped off somehow:

It's a bug. http-route-proxy using req.url as proxy route url, so it will be stripped off by express.

I had fixed it, please update with v0.2.0:

npm i [email protected]

https default is false, and route is optional, so the config can be more simple:

app.use('/api', proxyServer.connect({
  from: 'localhost:3000',
  to: 'localhost:3001'
}));

I tried a) uninstalling and reinstalling and b) installing [email protected] like you recommended. Neither worked. Also, it looks like the latest version is 0.10.4, not 0.2.0.

When I use remove route:

app.use('/api', proxyServer.connect({
  from: 'localhost:3000',
  to: 'localhost:3001' // api server
}));

app.use(proxyServer.connect({
  from: 'localhost:3000',
  to: 'localhost:3002', // web server
}));

Proxy says that it's working:

forward GET  /api/auth/facebook from localhost:3000 to http://localhost:3001/api/auth/facebook

But when I log req.url, it says /auth/facebook:

app.use('/', function(req, res, next) {
  console.log('hits here');
  console.log('req: ', req.url);
  next();
});

Output:

hits here
req:  /auth/facebook

http-proxy is a dependency. http-route-proxy latest version is 0.2.0.

But when I log req.url, it says /auth/facebook:

It's my mistake, i should rewrite req.url and req.path otherwise proxy-agent will use the req object that was modified by express directly. It will be fixed at v0.2.1. : )

v0.2.1 is published, using npm i http-route-proxy@latest to update.

Oh, whoops - I misread.

Works great - thanks!
