Based on the description, which includes things like emojis, improper list formatting (I edited it later to fix it), lacking explanations or citations for many arbitrary and unnecessary changes, this has many hallmarks that it was generated by an LLM. And based on many of the unnecessary, redundant, and CI-breaking changes -- see the in-line comments -- it seems like it was not verified by a human either...
Please do not spam maintainers with unverified, AI-generated changes that do not even follow the codebase style or package manager.
This resolves
TypeError: trimCanvas is not a function
Furthermore, while this lacks any sort of citations or proper explanations, this seems like this is supposed to be a fix for #128. This does not address my comments there nor the issues I have filed with build tools, as that bug is within those downstream build tools that users use, and not here in this repo.
You also have not provided a reproduction as evidence that this fixes that issue and this does not pass CI.

Please do not arbitrarily add libraries with arbitrary and conflicting versions

Please do not arbitrarily add entire package managers and their lockfiles. Use the existing ones

Please do not make arbitrary configuration changes. Many of these are also already configured as such, so you have largely duplicated config unnecessarily. The other changes, which similarly have no explanations for them, are conflicting and not needed

Please do not create arbitrary files and folders, particularly not unnecessary files, conflicting types, and duplicative folders.

The function should not no-op if there is a problem, especially with no logging to the user that something went wrong. Such behavior would be very misleading to users as it clearly breaks the API contract

Per vercel/next.js#78267, this should be automatically done by the bundler; TypeScript's esModuleInterop does this and several other steps.
Adding that into this codebase means ensuring it compiles correctly and is compatible with other bundlers, which is normally the responsibility of the bundlers themselves. Shifting the responsibility like that makes me reticent to include it, especially if it doesn't come with lots of compatibility verifications

Closing this as stale with no response from OP in 3+ weeks and still has many issues. There are ~3 LoC that are potentially useable here; if someone wants to take over this PR and try to make those work as a workaround to the issues of downstream bundlers, please detail why you believe this should belong in this project (vs the bundlers) and your testing against multiple bundlers to make sure the workaround works consistently. |
