@manniL / TheAlexLichter You have example for this ?

manniL•7mo ago

Very project specific IMO

Filipe Crespo Dev•7mo ago

my project have the same problem i saw the file in my project and the lib (nuxt3-leaflet) is responsible for more than 50% have a option for included a lib only in page necessary?

There are many options. I can discuss it with you if you feel like, hit me in DM (it depends on your project, on how many plugins you have, on how things get thrown around etc etc.)

manniL•7mo ago

of course, you can always lazy-load dependencies 🙂 but as Rigo said, it depends a lot on the project

Will that affect only bundling? Component still be server side rendered, right?

Filipe Crespo Dev•7mo ago

you have a example using lazy-load dependencies

manniL•7mo ago

it will effect bundling + what JS is loaded when but SSR will still work

Filipe Crespo Dev•7mo ago

@manniL / TheAlexLichter @Rigo I'm using SSR with Lazy in the components, but it doesn't work. the site still contains a lot of unused JS.

Filipe Crespo Dev•7mo ago

I've seen several configs, in vite, rollup, nitro and nuxt but all note remove the unused js

Can we see your plugins? How are you loading external libraries?

These are modules Do you have any plugins? Are you registering global components somewhere? I think I found the culprit

Nuxt leaflet module contains a plugin that load the whole leaflet package Which results as unused code in a page without leaflet map
