What is the best way to scale a vue app?

Question

Client side optimization

I have a simple application that fetches data from a database.
There are several modal windows, page layout, about 10 functions.
All this in one file and now it is 400 lines in size.
I have a question is this normal? If not, what is the best way to scale the application? Maybe there are some guides on how to store valid functions in one file, modal windows in another, etc.

Answer 1

It's called components.
