environment variables to be used in vitepress pages

[fessacchiotto]

hi! I'd like to retrieve the git build and branch data from an environment variable I can set/export at build time.
is there a way I can reference such an env variable somewhere in the markdown files or config files? tia!

Also looking for this answer. Is there any way?

This was quite difficult to figure out, but now I think I have it.

1. Thanks to How to using Vite Env Variables? #3896 , I realized that you need to place the .env variable inside the docs folder in your VitePress project.

docs
  |-- .env

Inside the environment variable file:

VITE_SOME_ENV_VARIABLE=SomeValue

3. Next, in your markdown page, add a <script setup> at the top of the page to bring in the environment variable. See below:

<script setup>
const someEnvVariable = import.meta.env.VITE_SOME_ENV_VARIABLE;
</script>

4. Then, you can reference your environment variable using Vue template syntax.

## Some Header

blah blah blah {{ someEnvVariable }} blah blah blah

You should just be able to use the variable directly, I believe.

someCommand -someArgument {{ someEnvVariable }}

Unfortunately no.

That's my markdown:

Works in Markdown: {{ $RELEASE_VERSION  }}

```
But not in code block {{ $RELEASE_VERSION  }}
```

and that's the result:

Try using ```bash-vue ``` instead of ```bash ```. I don't remember where or how I found that, but it works for my docsite: https://docs.didact.dev/quickstarts/create-flow-library

specify -vue prefix on fences - https://vitepress.dev/guide/using-vue#unescape-in-code-blocks

```txt-vue
But not in code block {{ $RELEASE_VERSION  }}
```
