Dev environment for building app


I’m currently developing an application that will rely on a subdomain-registrar and bitcoin transactions. To be able to do it properly, I need to setup a local (macos) and later a ci environment for it, but I’m having a hard time doing it. I’m currently trying to run the core integration_tests using docker to have such env available, but it is not going really well. I see some network errors:

FetchError: request to http://localhost:16268/v1/namespaces/id failed, reason: connect ECONNREFUSED

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

The output is really verbose, so it’s a bit hard to follow what’s happening.

While doing it, I noticed that there was a working docker-compose on the to-do tutorial that works fine for that version - Running on the version tagged there everything seem to work just fine.

I also noticed some places where a dev env setup was discussed. Like here: Setting up Developer Environments. And from those discussions I noticed the development mode and regtest mode on the mac application, but I couldn’t find an actual documentation of what it actually does.

All that said, I was wondering if anyone could point me in the right direction here. How can I have a working local environment to develop an application that relies on a subdomain-registrar?
