Problem Description

The current frontend modules relied upon by OpenWebUI are extremely numerous, resulting in extremely slow initial page load times (exceeding 10 seconds without any caching). This is particularly detrimental for new users.

Desired Solution you'd like

  1. Reduce the volume of static resources loaded on the first screen
  2. Dynamically load certain modules on demand
  3. Remove unnecessary dependencies

Related issues and PRs:

Result:

4217KB -> 1079KB = -74.41% js size

@tjbck Hello, could the downloadPdf method be encapsulated into a generic public function for easier dynamic import?

Not yet. I should be submitting one or two more pull requests. I'll close this issue myself once I'm done. Since it's a public holiday in my country, I haven't been very active on GitHub lately.
