# NoSQL JavaScript SDK

# Overview

[NoSQL](https://docs.catalyst.zoho.com/en/cloud-scale/help/nosql/introduction/) is a *Catalyst CloudScale* component that offers a fully managed, non-relational data storage feature that enables you to store semi-structured, unstructured, and disparate data of your application in either document-type or key-value based JSON format.

The *NoSQL JavaScript SDK* package enables you to perform CRUD operations in your NoSQL tables in your project. You can fetch the metadata of your NoSQL tables, as well as query tables or indexes of tables by specifying query conditions.

### Prerequisites

You need to install the following package to be able to use the NoSQL SDK methods.

```sh
npm install @zcatalyst/nosql
```

> **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 need to import the following module to use the NoSQL SDK methods.

```javascript
const { NoSQL } = require('@zcatalyst/nosql');//NoSQL module
```

### List of SDK Methods

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