WebAssembly in Action

D.6. Chapter 8

Chapter 8 has two exercises.

D.6.1. Exercise 1

Suppose you have a side module called process_fulfillment.wasm: how would you create a new instance of Emscripten’s Module object and tell it to dynamically link to this side module?

Solution

const fulfillmentModule = new Module({               1
  dynamicLibraries: ['process_fulfillment.wasm']     2
});

• 1 Creates a new WebAssembly instance of the main module
• 2 Tells Emscripten that it needs to link to the process_fulfillment side module

D.6.2. Exercise 2

What flag do you need to pass to Emscripten when compiling a WebAssembly main module in order to have the Module object wrapped in a function in Emscripten’s generated JavaScript file?

Solution

-s MODULARIZE=1
