Pointer events not firing when bundled with Parcel bundler

[danmarshall]

Hello,
Sorry if this is not the right place to file this bug, but it appears it might be related to #13 ?

Setup

Install the Parcel bundler
npm install -g parcel

Repro case

1. Clone deck.gl
2. Navigate to deck.gl/examples/website/plot/
3. Move this line of code from index.html to app.js:

App.renderToDOM(document.getElementById('app'));

4. parcel serve ./index.html --open

Expected

Mouse / pointer events to orbit the view

Actual

View does not respond to mouse

[danmarshall]

Note: it appears that the plot example is using deck.gl@6.2 which might not be using the most recent mjolnir.js

[Pessimistress]

Can you try the example on deck.gl's 6.3-release branch?

[danmarshall]

Ok, switched to the 6.3-release branch, still seeing the same issue. The browser field in package.json must be a WebPack-specific feature?

[danmarshall]

Hmmm I guess not - found some Parcel documentation that says it should: https://parceljs.org/module_resolution.html#package.json-%60browser%60-field

[danmarshall]

... but it sounds like it only works as an alias for main. Example:

{
  "main": "build/d3.Node.js",
  "browser": "build/d3.js",
  "module": "index"
}

It does not appear to work with the current:

  "browser": {
    "./dist/cjs/utils/hammer.js": "./dist/cjs/utils/hammer.browser.js",
    "./dist/esm/utils/hammer.js": "./dist/esm/utils/hammer.browser.js"
  }

Looks like it should? parcel-bundler/parcel#200

Can you inspect your bundle and see if hammer.js is included?

[danmarshall]

hammer.js was included. I will try to see if browser-resolve is finding it correctly. BTW it does say it should support the way you are doing it:

[danmarshall]

hmmm, perhaps it is a Windows thing? parcel-bundler/parcel#1883 (comment)

[danmarshall]

Hi @Pessimistress I have set up a simple repo to demonstrate this bug:
https://github.com/danmarshall/parcel-browser-field

I can close this issue if you aren't able to reproduce, it would then be a bug in Parcel.
Thank you for your patience! 👍

[Pessimistress]

Thanks for following up on this. Could you post an update here when it's resolved? I don't have a PC so it's been a little difficult for me to track compatibility on Windows.

[danmarshall]

Yes I will follow up here. Meanwhile, can you try to repro on your Mac?

[danmarshall]

Ok, bug does not repro on a Mac. Not your bug, sorry and thanks!

[danmarshall]

Bug happens when the files are in subfolders - backslashes on windows do not match forward slashes in a path. I've sent a PR to Parcel.
