ARM Template Viewer - Web Version

This is a standalone web version of the ARM Template Viewer extension for VS Code. This web app displays a graphical preview of Azure Resource Manager (ARM) templates. Once a template is loaded, the view will show all resources with the official Azure icons and also linkage between the resources.

Not all features from the extension are supported, for the full experience please use the extension

The main repo for the extension is here: https://github.com/benc-uk/armview-vscode

Notes & Project Structure

The application is written in TypeScript and is a standard Node.js + Express web application.

This app is effectively a wrapper around the VS Code extension, as such it is structured a little strangely. Effort has been made to use the code from the VS Code extension without any modification, and it is pulled into this repo via a Git submodule and resides in the armview-vscode/ directory

Source for this app is held in src and views folders

Build Process & Assets

When the app is built, it is TypeScript transpiled, along with the dependencies from armview-vscode and output is placed in dist directory

NOTE! An important part of the build is copyStaticAssets.js which takes static assets from both the src/public/ and armview-vscode/assets/ and copies them to dist. As follows

copy "src/public/*" -> "dist/public/"
copy "armview-vscode/assets/*" -> "dist/ext/"

Running Locally
