How to use APP_BASE_URL?

[use-strict]

You just pass it to docker run as an env variable:

docker run -p 80:80 -e APP_BASE_URL="https:\/\/my.domain.tld" alethio/ethereum-lite-explorer

I'm also getting some errors if I don't escape the slashes, so that's probably a bug which I'm going to investigate.

See also the examples here: https://github.com/Alethio/ethereum-lite-explorer#running-in-docker

Okey I understand now... as it says "It is used ONLY in index.html for og:tags" I misunderstood it and tried to change other og:tags like og:title.

Thanks @use-strict

Escaping issue will be fixed with #41

But is it the way if I want to change the og:title for example?

No, it's not. Env vars are there only for simple and very common customizations, like the node URL or the base URL. For more advanced customization, you can either mount a custom config.json or, if code changes are needed, you can build from source instead.

In the case of og:title, the string is the same as the application title, which is shown in the browser title bar. Because that is a localized string, it is taken from the src/translation/*.json files, which are packaged together with the source code and not configurable. In this case you could fork the repo and build from source, but it is an open discussion whether such customization should be supported OOTB.
