Embed TypeScript code in an HTML document
Solution 1:
Actually there are several projects that allow you to use TypeScript code like that - TypeScript Compile, ts-htaccess.
The catch here is that .ts code should be compiled into JavaScript - it can be done either at client-side (slow; the whole TSC should be loaded into the client as well) or at server-side (obviously faster, and it's far easier to leverage the cache on the compiled code).
Solution 2:
This is a version I wrote that directly uses the version from Microsoft/TypeScript/master so it always stays up to date: https://github.com/basarat/typescript-script
You can even point ts
to any other TypeScript version you might have and it will work fine 🌹
Solution 3:
A JavaScript library has already been developed for this purpose - it's called TypeScript Compile, and it allows typescript to be embedded in HTML (as shown above.)
