我正在构建一个应用程序,使用Nx进行模块化,使用Geckos进行服务器部分。使用 Nx 的 Node 默认 Webpack 5 配置,我在运行应用程序时收到此错误:
/Users/hgrzeskowiak/hugo-game/fresh-nx-geckos/nx-geckos-test/dist/apps/geckos-server-app/main.js:8
module.exports = require("@geckos.io/server");
^
Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/hgrzeskowiak/hugo-game/fresh-nx-geckos/nx-geckos-test/node_modules/@geckos.io/server/lib/index.js from /Users/hgrzeskowiak/hugo-game/fresh-nx-geckos/nx-geckos-test/dist/apps/geckos-server-app/main.js not supported.
Instead change the require of index.js in /Users/hgrzeskowiak/hugo-game/fresh-nx-geckos/nx-geckos-test/dist/apps/geckos-server-app/main.js to a dynamic import() which is available in all CommonJS modules.

以下是重现的步骤:
$ npx create-nx-workspace@latest nx-geckos-test
Need to install the following packages:
create-nx-workspace@latest
Ok to proceed? (y) y
✔ What to create in the new workspace · express
✔ Application name · geckos-server-app
✔ Use Nx Cloud? (It's free and doesn't require registration.) · No
> NX Nx is creating your v13.4.1 workspace.
To make sure the command works reliably in all environments, and that the preset is applied correctly,
Nx will run "npm install" several times. Please wait.
✔ Installing dependencies with npm
✔ Nx has successfully created the workspace.
$ npm run start

在这个阶段,默认的 Express 应用程序构建并运行。
现在我将apps/geckos-server-app/src/main.ts
README 中的内容替换为 Geckos 服务器示例:
import geckos from '@geckos.io/server'
const io = geckos()
io.listen(3000) // default port is 9208
io.onConnection(channel => {
channel.onDisconnect(() => {
console.log(`${channel.id} got disconnected`)
})
channel.on('chat message', data => {
console.log(`got ${data} from "chat message"`)
// emit the "chat message" data to all channels in the same room
io.room(channel.roomId).emit('chat message', data)
})
})
...并使用安装 geckos 服务器包
$ npm install @geckos.io/server
added 4 packages, and audited 785 packages in 7s

好的,是时候再次运行它了:
$ npm run start

> nx serve
> nx run geckos-server-app:serve

我测试了很多 Webpack 配置覆盖并type: "module"
在 package.json 中使用,但无济于事。无论我更改什么 webpack 设置,输出 main.js 看起来都基本相同。我尝试在应用程序的 webpack 覆盖配置中更改的内容:
module.exports = function(webpackConfig, context) {
webpackConfig.target = "async-node16";
webpackConfig.output.libraryTarget = "module";
webpackConfig.output.library = {type: "module"};
webpackConfig.output.chunkFormat = "module";
webpackConfig.experiments.outputModule = true;
console.log("webpack config:");
console.log(webpackConfig);
console.log("module rules:");
console.log(webpackConfig.module.rules);
return webpackConfig;
}
控制台登录配置验证脚本是否正在运行。
当我在转译输出中手动更改为时,该应用程序可以工作require
,import
但这不是一个可持续的解决方案。
我怀疑这个错误与 Geckos 是一个 ESM 包有关,而 Webpack 只使用require
而不是import
它应该使用的,但我找不到任何改变这种行为的方法。
有任何想法吗?
- 节点版本 16.13.0
- Nx 版本 13.4.1
