Expressjs based, not very standardised, may have maintainability problems in short/medium term.
Single active maintainer, only person to touch most files
Low system requirements

General Purpose languages

C# (.net core only)
- Language itself is absolute favorite, has fixed nullability problem in recent versions of c# (8.0+).
- Open source ecosystem is a bit immature (only recently open sourced), could be very good in another 5 years.
- Real unrestricted multithreading
Kotlin
- Basically Java++
Second best to C#, but has some strange design decisions like removal of static methods.

Guide to create and use ssh key based git deployment

Generate key with ssh-keygen, as path enter the same as suggested with a different filename of 'git'
run sudo nano ~/.ssh/config and add contents like

# add bitbucket deployment key to identity file
Host bitbucket.org
    User git
    IdentityFile ~/.ssh/git

Run within the repo that you cloned the self-hosted repository

sudo docker compose down --volumes

Then delete the folder you cloned the self-hosted repository to

sudo rm -R self-hosted

Check the scopes that you want to set it in, in my case I want it set for the entire application lifespan, so I set it in all possible scopes (to also effect scopes in flight).

export const setPostInitRelease = (releaseName: string) => {
    // set the release value using an event processor
    const eventProcessor = (event: { release: string | undefined }) => {
        event.release = releaseName
        return event
    };
 Sentry.getGlobalScope().addEventProcessor(eventProcessor)
