使用 wasm-pack 将一些 Rust 代码编译到 webassembly 之后带有选项 --target browser (默认)，我在 typescript/deps/ed25519xp 中得到以下文件:
我的 typescript 文件如下所示:
// typescript/src/index.ts
export { seed_from_phrase, gen_keypair } from "ed25519xp";
我的 package.json 像这样:
{
"name": "ed25519",
"version": "0.1.0",
"description": "ed25519",
"main": "typescript/dist/bundle.js",
"types": "typescript/src/index.ts",
"dependencies": {

},
"devDependencies": {

"@rollup/plugin-wasm": "^3.0.0",
"rollup": "^1.31.1",
"rollup-plugin-typescript2": "^0.26.0"
}
}
我的汇总配置如下所示:
// 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()
]
};
当我运行命令与汇总 (
node node_modules/.bin/rollup -c ) 捆绑时，我收到以下错误:(!) Missing exports

(!) Broken sourcemap
https://rollupjs.org/guide/en/#warning-sourcemap-is-likely-to-be-incorrect
Plugins that transform code (such as 'wasm') should generate accompanying sourcemaps
但是，在将 .wasm 文件评估为 WAT 时，导出似乎存在:
...
(func $seed_from_phrase (export "seed_from_phrase") (type $t6) (param $p0 i32) (param $p1 i32) (result i32)
...
(func $gen_keypair (export "gen_keypair") (type $t6) (param $p0 i32) (param $p1 i32) (result i32)

...

(我已经在 https://github.com/nmrshll/ed25519/tree/943fc841693401acc64260fc19d4dda08ae3503d 上传了整个 repo)
如何修复“缺少导出”捆绑错误？
最佳答案
使用 --target web 调用 wasm-pack反而。
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，我使用的是 wasm-bindgen 而不是 wasm-pack。
关于typescript - "Missing exports"将 wasm 与 rollup 捆绑在一起时，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60456142/
