How to add Language Support for extensions not on NPM?

[Liam F. O'Neill]

I'm new to JS so please forgive me if this is a silly question 😁

I would like to add Syntax support for Hashicorp Terraform (HCL) and Azure Bicep. In VS Code adding syntax highlighting is achieved by installing the following extensions:

Bicep: https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-bicep
Terraform: https://marketplace.visualstudio.com/items?itemName=HashiCorp.terraform

I can't find the equivalent of either of these on NPM so not sure how to proceed.

The README covers this: https://github.com/andrewbranch/gatsby-remark-vscode#using-languages-and-themes-from-an-extension

You still use npm but it reads from GitHub. Unfortunately some GH repos don’t behave well with this (e.g. if they need a build step to generate the JSON/YAML grammar files), in which case you’d have to build it yourself and bundle the result with your project, which is also mentioned in the README.
