Nuxt 2.0 build failing due to apache-arrow exports

[marr]

I am trying to import arquero into my nuxt v2 project. This is a client-only project, so ESM is being used directly. The errors I see are around apache-arrow:

ERROR in ./node_modules/apache-arrow/ipc/metadata/file.mjs Can't import the named export 'Builder' from non EcmaScript module (only default export is available)

ERROR in ./node_modules/apache-arrow/ipc/metadata/file.mjs Can't import the named export 'ByteBuffer' from non EcmaScript module (only default export is available)

That is when I import like this: import { from, op } from 'arquero'

Hmm. Not sure offhand what is driving the issue, as it appears at first glance to stem from Apache Arrow. In the meantime, you might consider filing an issue with the Arrow folks if you can isolate and replicate the issue outside of Arquero. I'll also flag @domoritz in case he has any insights.

I don't know what's causing this issue but would be happy to look into it if you can isolate it to arrow.

@domoritz Thanks for taking a look. Here is a barebones repro of what I'm seeing: https://github.com/marr/arrow-webpack

If you pull that down, and do:

npm install
npx webpack

You will see what I'm seeing:

ERROR in ./src/index.mjs 14:17-32 Can't import the named export 'tableFromArrays' from non EcmaScript module (only default export is available)

Likely a webpack v4 thing, but maybe worth investigating. Thanks! And thanks @jheer for the quick response.

We do test webpack in https://github.com/apache/arrow/blob/53b19a9e3fda0c71d8c0f6d5165caa573fb99a80/js/gulp/bundle-task.js#L99. However, it looks like the latest version is 5 and the repo is testing 4. Can you update webpack and try again?

[marr]

Thanks, yes I upgraded locally in my repro repo and it’s fine. Unfortunately, I am stuck on v4 due to a slog of upgrades needed to become “More modern” with vite, etc. nuxt is a pretty big audience and their v2 uses webpack4. I forsee lots of people getting held back with that until vue/nuxt3 become mainstream.

I see. I won't have the cycles to fix this myself but I'd be happy to review a pull request in arrow.
