Typed Secure Storage

Typed Secure Storage is a utility for secure, encrypted storage in the browser with type definition schema. It is built on top of the Web Crypto API and Local Storage. It is designed to be simple to use and easy to integrate into existing projects.

Features

• Type Definition Schema: Easily define the schema of the data you want to store and retrieve.
• Encryption: Data is encrypted using the Web Crypto API using AES-GCM.

Installation

bun install typed-secure-storage

Usage

Here's how to quickly get started with typed-secure-storage:

1. Define the schema

interface Todo {
  title: string;
  completed: boolean;
}

interface Schema {
  todos: Todo;
}

2. Create a new instance of TypedSecureStorage

import { createTypedSecureStorage } from "typed-secure-storage";

const secretKey = "your-secret-key"; // Replace with your secret key
const salt = "your-salt"; // Replace with your salt

const storage = await createTypedSecureStorage<Schema>(secretKey, salt);

3. Use the storage

const todo: Todo = {
  title: "Buy milk",
  completed: false,
};

// Save a single item
const res = await storage.set("todos", todo);
// Get a single item
const todo = await storage.get("todos", res.key);
console.log(todo.title); // "Buy milk"
// Get all items
storage.getAll("todos");
// Filter items
storage.filter("todos", (todo) => todo.completed);
// Remove a single item
storage.remove("todos", res.key);
