Service async function on onProxyReq

Having proxy configured with onProxyReq like:

proxy(gatewayUrl, {
  target: destinationUrl,
  pathRewrite: { [`^${gatewayUrl}`]: '' },
  changeOrigin: true,
  logProvider: () => logger,
  ...options,
  onProxyReq: async (proxyReq, req) => await addAuthHeader(proxyReq, req, redis),
});

Middleware is finishing request before promise is resolved. It is possible to service promise in proxy functions ?

@chimurai I have to deal with promises in both proxyReq and proxyRes functions. Would be very helpful to have to have these functions support promises.

Thanks @dpetrov this works here too. you dont even have to use onProxyReq, headers will get forwarded by the proxy later on

server.use((req, res, next) => {
  if (req.path === "/graphql" && req.method === "POST") {
    getSomethingAsync(req.session.id, (err, data) => {
      if (data) {
        req.headers["Authorization"] = `Bearer ${data.user.token}`
      }
      next()
    })
  } else {
    next()
  }
})
