# Cache JavaScript SDK

# Overview

[Cache](https://docs.catalyst.zoho.com/en/cloud-scale/help/cache/introduction/) is a *CloudScale* component, that can expertly handler small storage of data to facilitate retrieval of actively used data. Cache is best suited to handle your applications ephemera data or frequently accessed information. Cache actively reduces load on primary databases in memory-intensive real-time applications or microservices that demand sub-millisecond responses.

Catalyst Cache is divided into cache units called [segments](https://docs.catalyst.zoho.com/en/cloud-scale/help/cache/key-concepts/#segments). Each segment holds cache items (data) in the form of JSON key value pairs. The key and value are of the String data type.

The **Cache JavaScript SDK** package enables you to perform CRUD operations on the data stored in Cache. You can retrieve data, insert data, update and delete data from the Cache component through code.

### Prerequisites

You need to install the following package to use the Cache SDK methods.

```sh
npm install @zcatalyst/cache
```

> **Info:** Ensure that you have applied the [required authentication configuration](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/auth-config/node-consideration/) to use the SDK methods of this component.

### Import Requirement

You will need to import the following module to use the Cache SDK methods.

```javascript
const { Cache } = require('@zcatalyst/cache');
```

### List of SDK Methods

The following table contains the list of SDK methods that can be used to perform operations in Cache through code.
