@prettygoodtech/namespaced-web-storage v0.5.0

Namespaced Web Storage

A thin wrapper to use the Web Storage API with namespaces, easily, and safely. Built with TypeScript.

Features

• Works with localStorage, sessionStorage, and any Storage-compatible implementation like node-storage-shim for Node.js.
• Supports setItem, getItem, deleteItem, clear, and key methods.
• Supports length property.
• Supports dot and bracket property accessors.
• Supports Object.keys, Object.values, and Object.entries static methods.
• Small footprint with zero dependencies.
• TypeScript declarations.

Installation and Usage

First, install the package:

$ npm install @prettygoodtech/namespaced-web-storage

Now you can use NamespacedStorage to create a new instance based on your Storage implementation of choice:

import { NamespacedStorage } from "@prettygoodtech/namespaced-web-storage";

const nsStorage = new NamespacedStorage(window.localStorage, "my-prefix");

// Will store with key my-prefix:preferred-theme
nsStorage.setItem("preferred-theme", "dark");

// Will retrieve item with key my-prefix:last-accessed-on
const lastAccessedOn = nsStorage.getItem("last-accessed-on");

// Dot notation, will use key my-prefix:favorite
nsStorage.favorite = "sport-section"; 
delete nsStorage.favorite;

// Bracket notation, will use key my-prefix:favorite
nsStorage["favorite"] = "sport-section";
delete nsStorage["favorite"];

Caveats

• This package is still in its infancy and some features are not available yet.
• While you can use third-party Storage implementations, they might not follow the spec comprehensively. This means that any quirks they might have will still be present when using this package, and may even lead to unexpected errors. Your mileage may vary.
