Getting Started with JavaScript on NEAR: A Practical Guide

Ready to dive into building dApps on NEAR using JavaScript?Here's a step-by-step guide to get you started:

Step 1: Setting Up Your Development Environment

Before you can start writing code, you need to set up your development environment. 20 million JavaScript devs can now build applications on NEAR: KBW 2025 A student can build an app without needing to learn new languages without needing to learn new skills, said NEAR founder Illia Polosukhin.This involves installing the necessary tools and libraries.

Install Node.js and npm: Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a web browser. npm (Node Package Manager) is used to install and manage JavaScript packages.You can download Node.js from the official website: https://nodejs.org/
Install the NEAR CLI: The NEAR Command Line Interface (CLI) is a tool that allows you to interact with the NEAR blockchain from your terminal.You can install it using npm:
```
npm install -g near-cli
```
Create a NEAR wallet: You'll need a NEAR wallet to deploy and interact with smart contracts.You can create a wallet using the NEAR CLI:
```
near login
```

Step 2: Installing the JavaScript SDKs

Now that you have your development environment set up, you need to install the NEAR JavaScript SDKs.You can do this using npm:

npm install near-api-js

Step 3: Writing Your First Smart Contract

Let's write a simple smart contract that stores and retrieves a greeting message.

Create a new file called `greeting.js`:


// greeting.js
import { NearBindgen, near, call, view } from 'near-sdk-js';

@NearBindgen
class Greeting {
  constructor() {
    this.message = ""Hello, NEAR!"";
  }

  @view
  get_greeting() {
    return this.message;
  }

  @call
  set_greeting({ message }) {
    near.log(`Setting message to ${message}`);
    this.message = message;
  }
}

Compile the smart contract: You'll need to use a tool like `browserify` to bundle the JavaScript code into a format that can be deployed to NEAR. 20 million JavaScript devs can now build applications on NEAR: KBW 2025 20 million JavaScript developers will now have the ability to write blockchain smart contracts and build applications on the NEAR Protocol, after rolling out JavaScript SoftwareFirst install `browserify`:
```
npm install -g browserify
```
Then bundle your code:
```
browserify greeting.js -o greeting.bundle.js
```
Deploy the smart contract: Use the NEAR CLI to deploy the compiled smart contract to your NEAR account:
```
near deploy --wasmFile greeting.bundle.js --accountId your_account_id
```
(Replace `your_account_id` with your actual NEAR account ID).

Step 4: Interacting with Your Smart Contract

Now that your smart contract is deployed, you can interact with it using the NEAR CLI or the JavaScript SDKs.

Get the greeting message:
```
near view your_account_id get_greeting
```

Set a new greeting message:

near call your_account_id set_greeting '{""message"": ""Hello, World!""}' --accountId your_account_id

This is a basic example, but it demonstrates the core concepts of writing and deploying smart contracts on NEAR using JavaScript.The NEAR documentation provides more comprehensive examples and tutorials to help you build more complex dApps.
