Is install in an offline environment possible?

[canadabri]

I am wondering if the live editor can be installed in a offline (no internet) environment? If yes, are there install instructions for that (is there a manual installation method, or is docker the only way)?

I am assuming that Mermaid version would have to be v8.8.4 (this is the latest version I have found that Mermaid can be used without the Internet being available).

You could use a docker image to run Mermaid locally. I am using https://hub.docker.com/r/johnsinclair73/mermaid-live-editor#!

We cannot guarantee the safety of the code running in unofficial builds.

The official build is published here and can be run using

docker run --platform linux/amd64 --publish 8000:8080 ghcr.io/mermaid-js/mermaid-live-editor

Ok, if the mermaid live editor is running in an offline environment, is it possible to use that editor as a mermaid rendering engine for a different (still offline) site/app ? (example : some web apps can integrate external rendering engines by pointing to a source - in this case something like mermaid.js )

You would have to use the container for mermaid.ink if you need a renderer.

docker run --cap-add=SYS_ADMIN ghcr.io/jihchi/mermaid.ink

@canadabri I didn't understand what you meant by this. Mermaid does not need the internet to run.
It does have lazy loading, which means it loads related files, but if you have the full build available offline, it'll work fine.

If you use the mermaid.min.js file, it's a standalone bundle which will work without anything else.

@sidharthv96 Perhaps I misunderstood from another support forum (for a redmine plugin) why Mermaid could not be upgraded on a particular module for that system. They mentioned callbacks were preventing the upgrade to support mermaid v9 and above. I thought they were indicating that versions now called back to a CDN location of mermaid so an entirely locally saved JS file would not work/be possible.

I have a few web apps (redmine, wikiJS) installed for collab areas at work, and using the latest version of Mermaid would be great, but I am not sure how to upgrade them so I am still at v8.8.4 in those environments.

There single file versions of mermaid available (mermaid.min.js) that do not depend on CDNs. So I'm not sure what the blockers are for them. The size is bigger for the single file version, but we're working on a .tiny.js with a subset of features which is smaller.
