Cannot get basic POST examples to work

[cawoodm]

I need some help getting a basic POST example to work. GET seems to work fine.

Basically I can't see the middleware doing anything and the route never responds.

When I set a breakpoint on any of the handlers (see debugger statements below) they are never called. The only breakpoint I reach is in pathRewrite().

env.DEBUG is set to http-proxy-middleware* and no messages are displayed except:

INFO: [HPM] Proxy created: / -> http://127.0.0.1:8888

const host = 'http://127.0.0.1:8888'; // Fiddler
const {createProxyMiddleware} = require('http-proxy-middleware');
  app.use(
    '/users/login/cx',
    createProxyMiddleware({
      target: host,
      changeOrigin: true,
      pathRewrite: function (p, r) {
        // This breakpoint is reached
        return p.replace('/users/login/cx', '/cx/api/login');
      },
      on: {
        error: () => {
          // Breakpoint never reached!
          debugger;
        },
        open: () => {
          // Breakpoint never reached!
          debugger;
        },
        close: () => {
          // Breakpoint never reached!
          debugger;
        },
        proxyReq: (proxyRes, req, res) => {
          // Breakpoint never reached!
          debugger;
        },
        proxyRes: (proxyRes, req, res) => {
          // Breakpoint never reached!
          debugger;
        },
      },
    }),
  );

OK, the issue seems to be with some of our other express middleware.

I still cannot get any of the breakpoints to hit. This never logs anything:

        proxyReq: (proxyReq, req, res) => {
          console.log('proxyReq');
           },

OK, it seems NPM installs v2 by default and all the docs are for v3. This works for v2:

createProxyMiddleware({
      target: host,
      changeOrigin: true,
      logLevel: 'debug',
      onProxyReq: (proxyReq, req, res) => {
        console.log('proxyReq');
      },
      proxyRes: (proxyRes, req, res) => {
        console.log('proxyRes');
      },
      onError: () => {
        console.log('error');
      },
}),
