The official TypeScript support within AppBuilder is scheduled for version 2.2. It should be released in June, this year and it will cover all of the AppBuilder clients
Until then, the only way to benefit from TypeScript in AppBuilder projects is within Visual Studio. You will need the TypeScript Extension
installed. Then, inside Visual Studio from TOOLS > Options
, go to Text Editor > TypeScript > Project
and click on "Aromatically compile TypeScript files which are not part of a project" > "Use amd code generation for modules that are not part of a project"
. After this, include your ts file and select its action to TypeScriptCompile
I hope this helps.
