Cannot include apache-arrow when build the esm for broswer

[Roy-Kid]

Hi! Thanks for the brilliant and convenient tools!

I have an issue when I build the lib. My typescript project depends on apache-arrow, but it seems it cannot be included in the output(sorry for the language because Im not good at front-end technique).
Here is my config:

export default defineConfig({
  lib: [
    {
      format: 'esm',
      bundle: true,
      source: {
        entry: {
            index: './src/ts/index.ts'
        }
      },
      output: {
        distPath: {
          root: './dist/esm',
        },
        target: 'web'
      },
    }
  ],
});

My final output starts with this:

import * as __WEBPACK_EXTERNAL_MODULE__apache_arrow_ts_485105c1__ from "@apache-arrow/ts";
// or 
import ...... from "apache-arrow";

They have provided many kinds of https://arrow.apache.org/docs/js/index.html#packaging packaging, but I have tried many of them but cannot fix the problem. Can anyone help with this, how to include all deps in the final production.

Update:

One possible reason is my project contains multiple workspaces, and all packages I installed are stored in root/node_modules, not root/ws1/node_modules, maybe that's why rslib cannot find it? I use path in tsconfig to include other workspace and it works well.

I find this similar discussion: #806. As far as I understand, this identifier should be imported by another module in the packages or pipeline, but how if I only have a single module...

Bests,

Jichen

This means you're not bundling apache package since they're in the depedencies field in package.json instead of devDependencies (this is what https://lib.rsbuild.dev/config/lib/auto-external do).

If you want to make apache packages being bundled in your package, you could move it to devDependencies in package.json.

Thanks a lot for pointing this out. Now I can understand the logic...

One more question: when I install rslib with -D, it is append under devdependencies, which means I need to use output.external to exclude it manually. Is that a little bit unnatural?

@rslib/core will only be used in your config file which will not be bundled into final output I think. Similarly, for example, some testing tools and formatting tools are all written in the devDependencies.
