bundleNodeModules results in Error: 'default' is not exported

[johannes-z]

Stack Trace:
Error: 'default' is not exported by ..\..\..\..\node_modules\vue-infinite-loading\dist\vue-infinite-loading.js

I'm trying to create bundles with esm and umd, but the build fails because apparently the library I'm using doesn't export default. Apparently the library dist file is an umd file:

!function(t,e){"object"==typeof exports&&"object"==typeof module?module.exports=e():"function"==typeof define&&define.amd?define([],e):"object"==typeof exports?exports.VueInfiniteLoading=e():t.VueInfiniteLoading=e()}

Can you provide more information,
I just tested everything with vue-infinite-loading and it works fine.
I was able to get umd and esm bundle output.
What's the command you are running? or your config file

[johannes-z]

@hosein2398 Sorry yes you are right, I tried a minimal repro, and there it worked. There must be something wrong with the monorepo setup I got at work. I'll try to repro it again before I close this issue though

[johannes-z]

@hosein2398 I'm pretty sure it's because of the yarn-monorepo setup I have. It doesn't seem to resolve the symlinks correctly. See the path: ..\..\..\..\node_modules\vue-infinite-loading\dist\vue-infinite-loading.js.

Please check out this repo: https://github.com/johannes-z/bili-yarn-monorepo
You need yarn, just run yarn in the root and npx bili in the flexgrid package folder. It should fail with the above error message.

[johannes-z]

I added this to bili.config.ts, which seems to resolve this issue. I'm not sure if this is correct however.

  extendRollupConfig: config => {
    config.inputConfig.preserveSymlinks = true
    return config
  },

---

Actually this only worked, because I was building an esm bundle. Building umd still fails with the same error.

Adding exclude to the babel plugin seems to work, but this obviously seems like a dirty hack.

    babel: {
      exclude: /node_modules\/(?:vue-infinite-loading)/gi,
    },

Also, is this setting merged with the default exclude option?

exclude: ['transform-regenerator', 'transform-async-to-generator']
