getKeys(): string[]Parameters
None
Returns
string[]: An array of all keys in the Map store.
Description
The getKeys method retrieves all keys currently present in the Map store. This can be useful for iterating over all items in the store or checking if a specific key exists.
Example
import { createMapStore } from '@devlab/store';
type UserData = {
name: string;
age: number;
};
const userStore = createMapStore<UserData>({
initialData: new Map([
['user1', { name: 'John Doe', age: 30 }],
['user2', { name: 'Jane Doe', age: 28 }]
])
});
// Get all keys
const allKeys = userStore.getKeys();
console.log(allKeys); // ['user1', 'user2']
// Check if a key exists
const hasUser3 = userStore.getKeys().includes('user3');
console.log(hasUser3); // false
// Iterate over all users
userStore.getKeys().forEach((userId) => {
const userData = userStore.key(userId).get();
console.log(`${userId}: ${userData.name}, ${userData.age} years old`);
});This example demonstrates how to use the getKeys method to retrieve all keys, check for the existence of a key, and iterate over all items in the Map store.
