Set up proxy server with multiple targets?

cgd Published at Dev

cgd

I have 2 express servers:

api1
api2

Both are accessed locally using:

http://localhost:3000/news

http://localhost:3001/stock

My aim:

Access both express servers endpoints from a Proxy server on http://localhost:8008

My Issue:

I can only hit the first api1's endpoints

Any help would be greatly appreciated :)

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');

const api1 = createProxyMiddleware({
  target: 'http://localhost:3000'
});


const api2 = createProxyMiddleware({
    target: 'http://localhost:3001'
  });

const app = express();

app.use(api1);
app.use(api2);

app.listen(8008);

**edit1:

I tried this out, which works for api1 endpoints but not api2 endpoints.

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');

const apiProxy = createProxyMiddleware('/', {
  target: 'http://localhost:3000'
});
const apiProxytwo = createProxyMiddleware('/', {
  target: 'http://localhost:3001'
});

const app = express();

app.use(apiProxy,apiProxytwo);
app.listen(8008);

Still looking for a solution!!@! Help please!

Edit 2: Working solution

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
const app = express();


app.use('/news/*', createProxyMiddleware({ target: 'http://localhost:3000', changeOrigin: true ,}));
app.use('/stock/', createProxyMiddleware({ target: 'http://localhost:3001', changeOrigin: true, }));

app.listen(8008);

Edit 3(*bonus): Applying solution in container setup - have to change localhost to container names(news and stock) for proxy to work with containers correctly.

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
const app = express();


app.use('/news/*', createProxyMiddleware({ target: 'http://news:3000', changeOrigin: true ,}));
app.use('/stock/', createProxyMiddleware({ target: 'http://stock:3001', changeOrigin: true, }));

app.listen(8008);

proxy.js:

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
const app = express();


app.use('/news/*', createProxyMiddleware({ target: 'http://localhost:3000', changeOrigin: true }));
app.use('/stock', createProxyMiddleware({ target: 'http://localhost:3001', changeOrigin: true }));

app.listen(8008);

newsServer.js

const express = require('express');
const app = express();

app.get('/news/headlines', (req, res) => {
    res.send('hello from headlines')
});

app.get('/news/other', (req, res) => {
    res.send('hello from other')
})


app.listen(3000);

query http://localhost:8008/news/headlines => 'hello from headlines'

stockServer.js

const express = require('express');
const app = express();

app.get('/stock', function(req, res) {
    res.send('hello from api2');
  });


app.listen(3001);

query http://localhost:8008/stock => 'hello from api2'
