[Bug] Output chunk code sequence problem with splitting code？

[noyobo]

The issue project git repo https://github.com/noyobo/esbuild-issues/tree/chunk-order npm run build

esbuild config https://github.com/noyobo/esbuild-issues/blob/a4ecc9edf322c26f74aba5c1767379a20653e727/scripts/build.js#LL1C1-L1C1

There is a problem with the output chunk code.

https://github.com/noyobo/esbuild-issues/blob/a4ecc9edf322c26f74aba5c1767379a20653e727/dist/chunk-AFYZHPWT.js#L133

Line 133 calls dp_default.dpMaps but dp_default is defined on line 195 https://github.com/noyobo/esbuild-issues/blob/a4ecc9edf322c26f74aba5c1767379a20653e727/dist/chunk-AFYZHPWT.js#L195

actual execution throws an error Uncaught TypeError: Cannot read properties of undefined (reading 'dpMaps')

I haven't looked into the code you linked to. However, you should be aware that there are known ordering bugs with esbuild's current code splitting implementation: #399. This is explicitly called out at the top of the documentation for code splitting: https://esbuild.github.io/api/#splitting.

Sorry for not reading the docs carefully.

Can you refer to the code organization method of webpack, and register and call through the file name.

The order of the output code content is not the order of actual loading and parsing, but when the program starts to execute, it starts to execute according to the reference relationship.
