Access to Express app object

Feature Request

Is your feature request related to a problem? Please describe. I’m writing a probot app that has a few custom Express routes, and I want access to the Express app object to call things such as app.set('trust proxy', true)

Describe the solution you’d like app.express, maybe?

Describe alternatives you’ve considered Currently I hack my way around it with this code:

const v0 = app.route('/api/v0');
v0.use((req, res, next) => {
  req.app.set('trust proxy', true);
  next();
});

This sorta worked for me, but it makes my app a bit clunky (if I had written the app to begin with knowing the above it might’ve been better, but pivoting now is proving to be too difficult) - since I now know it’s possible, I guess this issue can be closed. Still, it would be nice to have (probot’s) app expose either the backing express app or at least expose some of these methods (set, get, use, and engine come to mind as useful methods to expose)

Anyways, just a thought - please feel free to close this if this isn’t a feature you think is worth adding

Yeah, I was totally wrong. So, you can get to the underlying express server but its a bit of a hassle at the moment. Probot works by calling probot run, a CLI tool that loads up your code as a function after its done all of its setup. You can instead take a programmatic approach and control the entrypoint yourself:

const { createProbot } = require('probot') 

const probot = createProbot({
  id: process.env.APP_ID,
  port: process.env.PORT || 3000,
  secret: process.env.WEBHOOK_SECRET,
  cert: process.env.PRIVATE_KEY
})

// This'd be your existing code, you'd want to `require` it in...
const myProbotApp = app => {
  app.on('...')
}

probot.load(myProbotApp)

const expressApp = probot.server

That I know works 😁.
