The `@push.rocks/webstore` module provides a high-performance storage solution for web applications, leveraging IndexedDB. This guide demonstrates how to use `@push.rocks/webstore` to store, retrieve, check, and manage data in the browser efficiently.
Before using `@push.rocks/webstore`, you must import and instantiate a `WebStore` class. Specify a database name (`dbName`) and a store name (`storeName`) in the options:
```typescript
import { WebStore } from '@push.rocks/webstore';
const myStore = new WebStore<{
[key: string]: any; // Define the shape of your store objects here
To store data, use the `set` method with a key and value. The value can be any object adhering to the store's object shape:
```typescript
await myStore.set('myKey', { some: 'data' });
```
### Retrieving Data
To retrieve data, use the `get` method with a key. This method returns a promise that resolves to the value associated with the key, or `undefined` if the key does not exist:
```typescript
const myData = await myStore.get('myKey');
console.log(myData); // { some: 'data' }
```
### Checking Data Existence
To check whether a key exists in the store, use the `check` method:
```typescript
const exists = await myStore.check('myKey');
console.log(exists); // true or false
```
### Deleting Data
To delete a specific entry, use the `delete` method with a key:
```typescript
await myStore.delete('myKey');
```
### Clearing the Store
To remove all entries from the store, use the `clear` method:
```typescript
await myStore.clear();
```
### Fetching All Keys
To retrieve all keys from the store, use the `keys` method. It returns a promise that resolves to an array of keys:
One of the strengths of `WebStore` is its built-in error handling using `smartpromise`. All the asynchronous operations (`init`, `get`, `set`, `delete`, `clear`, `keys`) inherently handle errors gracefully by catching them and allowing you to handle them with standard JavaScript try-catch or using `.catch` on the promises.
#### Error Handling Example
In TypeScript, you can write try-catch blocks to handle errors:
`@push.rocks/webstore` also includes a feature for caching typed requests using the `TypedrequestCache` class. This is particularly useful for caching API requests and their responses.
console.error('Error during typed request caching operations:', error);
}
}
main().catch(console.error);
```
### Conclusion
The `@push.rocks/webstore` package provides a flexible and efficient way to handle browser storage and caching. With features like error handling, typed request caching, and easy-to-use APIs, it can significantly improve performance and maintainability in web applications.
