Reproduce Steps

pnpm i
pnpm build

[lzxb]

If mode equal to production , It is ok。

The reason of the verbose output is due to lacking the following configurations:

  experiments: {
    outputModule: true,
+    rspackFuture: {
+      bundlerInfo: {
+        force: false,
+      },
+    },
  },
  optimization: {
    minimize: false,
+   concatenateModules: true,
  },

1. manually enable concatenateModules in development mode, as it's the premise of modern-module. I think it's reasonable to check it's enabled before build by default.
2. disable bundlerInfo to avoid unneed debug info.

I use modern-module, which can cause many module compilation errors. Canmodule support export *?

Output

[lzxb]

The content output here has lost its export.

I use modern-module, which can cause many module compilation errors.

Could you provide the error so we can fix it?

Canmodule support export *?

No.

[fi3ework]

A reproduce repository please? It is hard to reproduce via a screenshot.

I updated code.

[fi3ework]

Same as web-infra-dev/rslib#316.

Workaround for now it's to use two splitted build process.

[fi3ework]

Specify different layer (https://rspack.dev/config/experiments#experimentslayers) for each entry is also a workaround.

[lzxb]

Is there a plan to solve it in the future?

[fi3ework]

It should be resolved, but the time is not promised.

[lzxb]

I'll try usingexternals first to solve it

[lzxb]

I have solved the above problem using externals. But we encountered a new problem

[lzxb]

1. Clone https://github.com/dp-os/gez/tree/feat-modern-module
2. pnpm i
3. pnpm build:packages
4. cd examples/ssr-html
5. pnpm dev
   

pnpm build:ssr is ok.

[lzxb]

Build target node is ok.

[fi3ework]

It's because of the https://github.com/dp-os/gez/blob/78da1962deea63a7e4efdf91873448984aea8e4e/packages/rspack/src/config.ts#L94-L96 break the concatenation premise of modern-module. modern-module is now designed mainly to build compact ESM output and not tested to work with HMR now.

I plan to use Rspack to build a pure ESM application, but it seems like I can't keep going now.

[lzxb]

I have tested many and themodule is now stable, but it does not support export *。

[lzxb]

modern-module output is unstable，Built at different times, the output results are inconsistent. Sometimes normal, sometimes incorrect.
