❌ Don't load multiple versions

[Vike][Warning] [email protected] and [email protected] loaded which is highly discouraged

This warning means that two different Vike versions are loaded ([email protected] and [email protected]).

This must be avoided in production — use a single Vike version instead.

⚠️
Never deploy to production if you see this warning. Otherwise, you risk:

Bugs that cannot be fixed (Vike internally assumes that only a single Vike version is loaded).

Client-side bloat (unnecessary KBs loaded as multiple Vike versions are loaded).

It may even lead to security issues.

That said, you can temporarily ignore the warning during development. (For example, it's common to temporarily link npm packages during development which can lead to multiple node_modules/vike/ installations with different versions.)

Contributions welcome to create a guide on how to dedupe multiple Vike versions.
