@babel/plugin-proposal-import-wasm-source

Transforms import source declarations to WebAssembly.Module objects, assuming that import source is being used to import the source of a WebAssembly Module.

The transformation applied by this plugin depends on your top-level targets to detect whether the generated code should be compatible with Node.js, browsers, or both. When targeting Node.js, the generated code will also change depending on whether you are compiling modules to CommonJS or not.

警告

This plugin cannot be used when compiling modules to AMD, SystemJS, or UMD.

Example

input.js
import source libMod from "./lib.wasm";

will be transformed to

output.js
const libMod = await WebAssembly.compileStreaming(fetch(import.meta.resolve("./lib.wasm")));
