Frontend vs backend

When to use operators, prototypes, or core functions.

Frontend

Prefer operators or core functions/classes (tree-shakeable).

typescript

import { format, maskCpf, split } from '@koalarx/utils/operators';

format(new Date('2023-10-01'), 'dd/MM/yyyy').split('/');
maskCpf(user.cpf).toString();
split(csvLine, ',').clearEmptyValues();

Avoid import '@koalarx/utils/prototypes' in the browser bundle.

Backend

Prototypes in main give global DX:

typescript

import '@koalarx/utils/prototypes';

cpf.maskCpf();
valor.maskCoin();

Each realm (process, worker, SSR, tests) needs the import on its entry.
