# Initialize and Install the Required Dependencies

To run the application on a Node.js Express framework,  let’s initialize the `Catalyst Node.js SDK`, Node modules, `Axios` and `Express` package for your application.

Enter the following command in your CLI in your project directory `/LeadManager` to initialize the Node modules:

```sh
npm init

* Enter "`leadmanagerapp`" as the package name, and "`index.js`" as the entry point. You can also just click **Enter** to use the default names generated by NPM, or enter any name of your preference.

* Click **Enter** for the rest of the prompts, and complete the initialization. Your preferences will be stored in a [`package.json file`](https://docs.npmjs.com/cli/v10/configuring-npm/package-json). You can review your options in the terminal and confirm your preferences by entering "**yes**".

* Create a new file in your project directory and name it "`index.js`" If you have provided a different name for your entry point, ensure you provide the same name here.

### Install Express

Now, let's install the `Express` package in your project’s root folder using the following command:

```sh
npm install express
```

### Install Axios

Now, let's install the `Axios` package in your project’s root folder using the following command:

```sh
npm install axios
```

### Install Catalyst Node.js SDK

We will utilize Catalyst components in this app. To use them, you will also need to install the [Catalyst Node.js SDK](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/overview/) package in your project’s root folder using the following CLI command:

```sh
npm install zcatalyst-sdk-node
```

Now your directory will contain the `node_modules` folder, the `package.json`, `package-lock.json`, and the `index.js` file, in addition to the existing files.
