WebAssembly.compile() function compiles WebAssembly binary code into a WebAssembly.Module object. This function is useful if it is necessary to a compile a module before it can be instantiated (otherwise, the WebAssembly.instantiate() function should be used).

句法

Promise<WebAssembly.Module> WebAssembly.compile(bufferSource);
					

参数

bufferSource

A typed array or ArrayBuffer containing the binary code of the .wasm module you want to compile.

返回值

A Promise 解析为 WebAssembly.Module object representing the compiled module.

异常

• 若 bufferSource is not a typed array ， TypeError is thrown.
• If compilation fails, the promise rejects with a WebAssembly.CompileError .

范例

Using compile

The following example compiles the loaded simple.wasm byte code using the compile() function and then sends it to a worker 使用 postMessage() .

var worker = new Worker("wasm_worker.js");
fetch('simple.wasm').then(response =>
  response.arrayBuffer()
).then(bytes =>
  WebAssembly.compile(bytes)
).then(mod =>
  worker.postMessage(mod)
);
					

注意 : You'll probably want to use WebAssembly.compileStreaming() in most cases, as it is more efficient than compile() .
