TypedStorage

There are some repetitive logics for Web Storage:

• JSON.parse and JSON.stringify
• try/catch
• ...

TypedStorage makes Web Storage easy-to-use and type-safe by abstracting those repetitive logics.

Note

TypedStorage is subpath exported module. You should use @toss/storage/typed to use it.

Example

import { TypedStorage } from '@toss/storage/typed';

type SupportedOS = 'ios' | 'android';
const count = new TypedStorage<SupportedOS>('os', { initialValue: 'ios' });
count.get(); // 'ios'
count.set('android'); // 'android'
count.set('toss-os'); // Type Error

import { TypedStorage } from '@toss/storage/typed';

const count = new TypedStorage('count', { initialValue: 0 });
count.get(); // 0
count.set(1); // 1
count.set('not a number'); // Type Error
