Adding Compiled WebAssembly Modules to TV Applications

This topic describes how to add already existing WebAssembly modules and their accompanying files to a TV application project.


To embed an existing, working WASM application, in a TV application you need the following:

  • Compiled WASM module(s) (".wasm")
  • WASM source mappings ("" files) - required for source level debugging only
  • WASM modules' counterpart JavaScript code - either generated by Emscripten SDK or custom
  • HTML code in which the modules are embedded

You can use this example WebAssembly application for reference.

Embedding a WebAssembly Application in a TV Application

  1. Create a new TV application project if not existing yet (it doesn't have to be a WebAssembly-enabled project since there will be no C/C++ source code to build).
  2. Copy all of the WASM module files to the newly created TV application project. To find the project's location:
    • Right click the project and select "Properties"
    • Click the "Resource" in the project's properties tree
    • Check the "Location" property (see Fig. 1)
      Figure 1. Check project's location

If you used the example WebAssembly application, extract all of its files to the TV application project location.

  1. Refresh the project by clicking it in the Project Explorer and pressing F5 key.
  2. Make sure that <content src="index.html"/> tag in the config.xml file points to an HTML file that either embeds the WASM modules directly or refers other HTML/JS files that do that.

    In case of the example WebAssembly application the tag should read as: <content src="hello.html"/>

Once all the required files are in place you can launch the TV application to verify that it works properly - see Launching for details.
