Question

使用带有选项--target browser（默认）的typescript/deps/ed25519xp将一些rust代码编译到webassembly之后，我在// typescript/src/index.ts export { seed_from_phrase, gen_keypair } from "ed25519xp";中得到以下文件：

ed25519xp_bg.wasm
ed25519xp_bg.d.ts
ed25519xp.d.ts
ed25519xp.js
package.json

我的打字稿文件看起来如下：

{
  "name": "ed25519",
  "version": "0.1.0",
  "description": "ed25519",
  "main": "typescript/dist/bundle.js",
  "types": "typescript/src/index.ts",
  "dependencies": {
    "ed25519xp": "file:typescript/deps/ed25519xp"
  },
  "devDependencies": {
    "@types/node": "^13.7.1",
    "typescript": "^3.7.5",

    "@rollup/plugin-wasm": "^3.0.0",
    "rollup": "^1.31.1",
    "rollup-plugin-typescript2": "^0.26.0"
  }
}

我的package.json是这样的：

// rollup.config.js
import resolve from "@rollup/plugin-node-resolve";
import commonjs from "@rollup/plugin-commonjs";
import typescript from "rollup-plugin-typescript2";
import multi from "@rollup/plugin-multi-entry";
import wasm from "@rollup/plugin-wasm";

export default {
  input: [
    "typescript/deps/ed25519xp/ed25519xp_bg.wasm",
    `typescript/src/index.ts`
  ],
  output: {
    sourcemap: true,
    format: "iife",
    name: "ed25519",
    file: `typescript/dist/bundle.js`
  },
  plugins: [
    multi(),
    resolve({
      browser: true,
      extensions: [".js", ".ts", ".wasm"]
    }),
    commonjs({
      include: [
        `typescript/**/*.js`,
        `typescript/**/*.ts`,
        `typescript/**/*.wasm`,
        "node_modules/**"
      ]
    }),
    typescript(),
    wasm()

    // If we're building for prod (npm run build
    // instead of npm run dev), minify
    // terser()
  ]
};

我的汇总配置如下：

node node_modules/.bin/rollup -c

但是，将.wasm文件评估为WAT时，似乎存在出口：

如何解决“缺少出口”捆绑错误？

Answer 1

改为使用--target web调用wasm-pack。

文档：https://rustwasm.github.io/docs/wasm-pack/commands/build.html#target

这就是使用类似配置为我消除这些错误的原因。虽然，我使用wasm-bindgen代替wasm-pack。

Answer 2

有点晚了，但是我在使用带有已编译的 wasm-pack 节点模块的汇总时遇到了同样的问题。（在我的例子中，我的主页面使用 wasm，我也想在 service worker 中使用相同的 wasm 文件）。

我很快编写了一个汇总插件 (poc)，它允许您使用 wasm-pack 节点模块并将所需的 wasm 文件复制到您的输出目录。

如上一个答案所述，wasm-pack 模块需要使用“--target web”构建。

如果你想直接编译你的 Rust 代码，我建议你使用 Rust 插件进行汇总。

您可以在这里找到rollup-wasm-pack-import。

将浪费与汇总捆绑在一起时“缺少出口”
