How to execute the code packed by preEntry config before main.xx.js loaded?

[tailgo]

I'm trying to preload some code and execute it before main.xx.js is loaded, but it seems that the code from the preEntry configuration doesn't execute until main.xx.js has loaded. I can't find anything about this mechanism in the documentation. Does anyone have any ideas?

The code in preEntry is generated in the same build as the rest of your code and may share dependencies with other code, so it will wait until the main bundle is loaded before executing.

If you want to execute the code in preEntry immediately after loading, you should bundle the preEntry code in a separate build process and load it using a script tag.

Which API should be used, and could you provide an example?
