Calling app.use before setting up the routes

[opal goblet]

When I try to use session.destroy() I get the error:

[Nest] 73846  - 02/11/2024, 9:42:58 PM   ERROR [ExceptionsHandler] Cannot read properties of undefined (reading 'req')
TypeError: Cannot read properties of undefined (reading 'req')
    at destroy (<>/extremepriv/privateserver/node_modules/express-session/session/session.js:110:15)

    at destroy (node:internal/util:428:12)
    at AppController.root (<>/extremepriv/privateserver/src/app.controller.ts:13:41)

The lines that are causing an error are commented out in this file, I would like to uncomment to prevent session reuse:

This solution suggests to call app.use(session) before setting up the routes, how is that done in NestJS?

How did you set up sessions, if you didn't use app.use?
https://docs.nestjs.com/techniques/session

Ah. you are using app.use. The invocation before setting up routes happens automatically under the hood in Nest.

What is the purpose of using promisify?

[opal goblet]

Does it? Thank you!

I will try without promisify, that was to simplify my code using async.

I will need to return a promise anyway right?

[rancid sigil]

I don't believe the session methods are async to begin with. @opal goblet

[opal goblet]

they are, they require a callback

[rancid sigil]

@opal goblet - Yeah, well. Just because a function has a callback as an argument, doesn't make it asynchronous.

I've set up the code in github.dev (codespaces) and I changed the calls to back to normal calls and everything works. I just removed the regenerate calls. What was the purpose of doing that?

Hi, did you remove the code? I realised what you mean with callbacks but I can't get my code to work.

[opal goblet]

I finally got it!

The doc does say the function is asynchronous. https://github.com/expressjs/session?tab=readme-ov-file#sessionregeneratecallback
