Usage with middlewares

[karladler]

Is it possible to use this together with middlewares? I would like to check and modify some headers in the corresponding middleware.

• If you want to do something at request header or response header, you can use option. The usage is the same as http-proxy-middleware is. example:

  options = {
  targets: {
  '/user': {
    // this is option of http-proxy-middleware
    target: 'http://localhost:3001', // target host
    changeOrigin: true, // needed for virtual hosted sites
    onProxyRes: (proxyRes, req, res) => {
      proxyRes.headers['x-added'] = 'foobar' // add new header to response
    }
  }
  }
  }

options look at http-proxy-middleware options

• Is it possible use this middleware with other? yes, it is. If you want to check something,just write a middleware and put it in front of koa2-proxy-middleware...
