Question on how to run standalone from command-line

Hello again,

I have a question about how I could go about creating a mockttp standalone server through the command line that would always be listening.

What I am trying to accomplish is to have a server that is always running in one shell, that would pass through any requests that are not matching a rule. Then, I want to have tests that can configure the mock server to add/remove rules using code such that I can intercept and do the rewrites accordingly and reset to a default state when it finishes.

I read that I can do Running mockttp -c [test command], to start the server before your tests, and automatically shut it down afterwards. but I don’t want the server to shutdown.

Is this possible?

Yes, that looks like correct to me! Sounds like everything’s working for you now, so I’m going to close this, but feel free to reply here if you’re still having trouble, or open a new issue for anything else that comes up.

Excellent! I think this is what I was looking for!

I couldn’t get the event-based startup/shutdown to work because I was somehow getting into a loop of starting and stopping itself, but this worked well:

const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.get('/connect', (req, res) => {
  remoteServer.stop();
  res.send('Connection established');
});

app.get('/disconnect', (req, res) => {
  remoteServer.start(8000).then(() => {
    remoteServer.forUnmatchedRequest().thenPassThrough();
  });
  res.send('Connection disconnected');
});

app.listen(port, () => {
  console.log(`Listening at http://localhost:${port}`);
});

const standaloneServer = mockttp.getStandalone({
  debug: true,
  serverDefaults: {
    https: {
      keyPath: '../config/mockttp/ca.key',
      certPath: '../config/mockttp/ca.crt',
    },
  },
});
standaloneServer.start().then(() => {
  console.log('Standalone server started');
});

const remoteServer = mockttp.getRemote();
remoteServer.start(8000).then(() => {
  remoteServer.forUnmatchedRequest().thenPassThrough();
});

I would then make a GET request before and after tests to release the port I was using so I could connect with a remote server connection.
