Encryption

The persist and encrypt properties in options enable data persistence and encryption support for State-Jet.

✅ Example: Persisting a Counter State Across Reloads with persist and encrypt options

Create a file at src/components/TodoApp.tsx:

src/components/TodoApp.tsx

import { useStateGlobal } from "state-jet";

export type Todo = { id: number; text: string; completed: boolean };

const todoState = useStateGlobal<Todo[]>("todos", [], { persist: true, encrypt: true });

export default function TodoApp() {
  const todos = todoState.useState() as Todo[];
  const addTodo = (text: string) => {
    const newTodos = [...todos, { id: Date.now(), text, completed: false }];
    todoState.set(newTodos);
  };

  return (
    <div>
      <h1>Todo List</h1>
      <button onClick={() => addTodo("New Task")}>Add Todo</button>
      <ul>
        {todos.map((todo) => (
          <li key={todo.id}>{todo.text}</li>
        ))}
      </ul>
    </div>
  );
}

✅ Example: Persisting a Counter State Across Reloads without persist and encrypt options

The saveEncryptedState and restoreEncryptedState functions helps to override existing global state without persist, encrypt options

This example demonstrates how to:

1. Save the counter state with encrypt (saveEncryptedState)
2. Restore it when the page reloads with decryption (restoreEncryptedState)

By default when you add persist and encrypt as true, State-jet internally call above two functions. But this example helps to achieve overriding from toplevel.

Create a file at src/components/TodoApp.tsx:

src/components/TodoApp.tsx

import { useStateGlobal, saveEncryptedState, restoreEncryptedState } from "state-jet";

export type Todo = { id: number; text: string; completed: boolean };

const todoState = useStateGlobal<Todo[]>("todos", restoreEncryptedState("todos", []) as Todo[]);

export default function TodoApp() {
  const todos = todoState.useState() as Todo[];
  const addTodo = (text: string) => {
    const newTodos = [...todos, { id: Date.now(), text, completed: false }];
    todoState.set(newTodos);
    saveEncryptedState("todos", newTodos); // Save new state
  };

  return (
    <div>
      <h1>Todo List</h1>
      <button onClick={() => addTodo("New Task")}>Add Todo</button>
      <ul>
        {todos.map((todo) => (
          <li key={todo.id}>{todo.text}</li>
        ))}
      </ul>
    </div>
  );
}
