Remove dependency on "example.org"

Description

Hello.

I'm trying to build hedgedoc in an offline mode. I need this because openSUSE Build Service workers do not have networking during the build process, so I have to download everything in advance.

Steps to reproduce

For this I do the following:

1. download the latest hedgedoc snapshot:

$ curl -LO https://github.com/hedgedoc/hedgedoc/archive/5775b07b2dde5ce5ef82b678fd7ebbdc1ca213f7.tar.gz

2. unpack it:

$ tar xf 5775b07b2dde5ce5ef82b678fd7ebbdc1ca213f7.tar.gz

3. cd into it:

$ cd hedgedoc-5775b07b2dde5ce5ef82b678fd7ebbdc1ca213f7/

4. install node_modules:

$ YARN_GLOBAL_FOLDER=../yarn yarn install
# logs below

5. disable networking; I emulate this step with a network namespace in Linux:

$ sudo ip netns add hedgedoc2

6. run build without networking:

$ sudo ip netns exec hedgedoc2 sudo -u myuser bash -c 'YARN_GLOBAL_FOLDER=../yarn yarn build'
# logs below

7. the build fails while yarn does something that requires connection to example.org

Expected behaviour

I'd like to be able to build hedgedoc completely offline. I can download anything I need in advance, but the build process has to be successful on a disconnected node.

Additional context

What do I do wrong? I'd appreciate any help on the matter.

Thank you.

As far as I've seen it, these files could be responsible:

• frontend/src/utils/base-url-from-env-extractor.ts
• backend/src/realtime/websocket/utils/extract-note-id-from-request-url.ts

All other resources pointing to external domains are either test files, docs or comments giving an example.

The backend has nothing to do with this. During build time the frontend tries to pre-render as much content as possible. This is done using server side rendering. But during server side rendering it tries to contact the backend for e.g. runtime configuration.
During build time the backend URL is "example.org" . That's why the build process tries to access the network.
Should be easy to fix by just failing without a request while building.

You're right. However this should be fixed soon, as it's also against the usage guidelines for the example domains.

please do not design applications that require the example domains to have operating HTTP service
