Do you see some benefit to refer minified prod build in tests? For once it might be harder to run debugger with it. You could simply refer to ../dist here which will pickup dev build so it would be less verbose.

no, these are the performance test, not the unit tests. So they won't really assert anything and arent to be relied upon for correctness. Using a prod build to better reflect raw production performance

Interesting. Shouldn't you refer to src in test files and let it translated to dist with this?

yeah, this makes the tests behave as if immer was a dependency. So if anything is referred from src that is also exported from the index, it is fine, otherwise it will become undefined, so any graybox tests are marked to be not included in this build config

@markerikson (and others) the new version can be tried as immer@6.0.0-alpha.3. Installation instructions can be found here: https://github.com/immerjs/immer/blob/multi-bundle/docs/installation.md#pick-your-immer-version

danielkcz · 2020-02-25T21:18:33Z

@mweststrate You should definitely fix that main field I pointed above, it won't work like that in any nonESM environment. You can see here there is no "immer.js" dist file with TSDX: https://unpkg.com/browse/immer@6.0.0-alpha.3/dist/

markerikson · 2020-02-26T03:18:55Z

Can confirm the entry point issue broke things. I just tried alpha.3, and yeah, all our tests blew up with Jest saying it can't find Immer. Hand-editing node_modules/immer/package.json let them run okay.

@mweststrate , can you put out another alpha? (Given the time zone difference, you're probably asleep now, so I'll have to try this again tomorrow night.)

Having said that, I also tried a local test build of RTK with the hand-edited copy of Immer 6, and I can confirm that the size of Immer in a demo app bundle is smaller.

Webpack reports the demo app's main.js went from 19.1K down to 11.5K for Immer 6 with no plugins, and 13.5K with the ES5 plugin.

source-map-explorer was previously showing Immer as being around 12K by itself, I think. It now shows 6.64K with no plugins and 8.61K with the ES5 plugin.

So, looks like that plugin adds about 2K in this example, but overall, a definite win.

mweststrate · 2020-02-26T04:48:57Z

I'm actually in CA at the moment :) Just pushed an update (didn't test it, let me know if it isn't ok) Yeah those numbers align with my expectations for non-gzipped code. I think the ES5 plugin could actually be pruned a little bit more as there seems to be some almost-duplication, maybe in a next version.
