Resolve promise before registering middleware and exposing routes

I need to fetch a secret from a secrets manager using an async request to use for my middleware, but I find that I get no response or a timed out one when I try and wrap my middleware and routes in a promise chain.

getSecret().then(secret => {
  const strategy = new OAuth2Strategy({
    secret: secret
  }, function (accessToken, refreshToken, params, profile, done) {
    done(null,{data: 'some user data'});
  })


  passport.use('oauth2', strategy);
  refresh.use('oauth2', strategy);

  app.get('/my_route', async function (req, res) {
    ...
  })
})

What is the best way to deal with async code that needs to be resolved before I expose my routes?

Please see https://github.com/vendia/serverless-express/blob/mainline/UPGRADE.md for info on upgrading. I haven’t tested with Nest. Let me know if you hit any issues. If you could send a PR with a minimum Nest example, that’d be great!

Will definitely do by end of this week.

Sorry, that should be return serverlessExpressHandler(event, context). I don’t have any complete examples though I recall seeing some Issues here with comments doing similar things. Definitely a common/valid use case that I should add an example for.
