汇总：从外部模块捆绑/嵌入 wasm 代码

Question

使用汇总，我试图捆绑一个 typescript 库，该库导入和调用包含 wasm 文件的 npm 模块。

只有生成的包不包含 wasm 文件内容的痕迹。我怎样才能强制它也捆绑 webassembly？

---

这是我尝试过的关键文件：

// typescript/src/index.ts

import * as libEd from "ed25519-raw";

export const seed_from_phrase = libEd.seed_from_phrase;
export const gen_keypair = libEd.gen_keypair;

我的 package.json 是

{
  "name": "ed25519",
  "version": "0.1.0",
  "description": "ed25519",
  "main": "typescript/dist/bundle.cjs.js",
  "types": "typescript/src/index.ts",
  "dependencies": {
    "ed25519-raw": "git+https://github.com/cmanteiga/ed25519-raw"
  },
  "devDependencies": {
    "@types/node": "^13.7.1",
    "typescript": "^3.7.5",
    "@rollup/plugin-commonjs": "^11.0.2",
    "@rollup/plugin-multi-entry": "^3.0.0",
    "@rollup/plugin-node-resolve": "^7.1.1",
    "@rollup/plugin-wasm": "^3.0.0",
    "rollup": "^1.31.1",
    "rollup-plugin-typescript2": "^0.26.0"
  }
}

最后汇总配置是

{
  "name": "ed25519",
  "version": "0.1.0",
  "description": "ed25519",
  "main": "typescript/dist/bundle.cjs.js",
  "types": "typescript/src/index.ts",
  "dependencies": {
    "ed25519-raw": "git+https://github.com/cmanteiga/ed25519-raw"
  },
  "devDependencies": {
    "@types/node": "^13.7.1",
    "typescript": "^3.7.5",
    "@rollup/plugin-commonjs": "^11.0.2",
    "@rollup/plugin-multi-entry": "^3.0.0",
    "@rollup/plugin-node-resolve": "^7.1.1",
    "@rollup/plugin-wasm": "^3.0.0",
    "rollup": "^1.31.1",
    "rollup-plugin-typescript2": "^0.26.0"
  }
}

（完整的示例存储库可在https://github.com/nmrshll/ed25519 获得）

然后通过生成包 node node_modules/.bin/rollup -c

它包含一个function _loadWasmModule (sync, src, imports)但从未被调用过的，并且没有嵌入式 webassembly 的痕迹（我希望它是一个硬编码的 base64 字符串）。

我怎样才能解决这个问题 ？

编辑：包含在“ed25519-raw”中的 wasm 文件是wasm-pack使用选项生成的--target web

这很重要，因为wasm-pack使用选项--target browser（默认）运行会生成不同的输出（嵌入了 wasm 但有编译问题）
