Get started building on Berachain and using the JSON-RPC API
To use the Berachain App API you'll need to create a free Alchemy account first!
Introduction
Berachain is an EVM-compatible blockchain designed to provide high performance, scalability, and security for decentralized applications (dApps). Known for its innovative features and efficient transaction processing, Berachain offers a robust environment for deploying Ethereum-based applications.
Please note that we currently only support the bArito testnet
What is the Berachain App API?
The Berachain App API facilitates interaction with the Berachain network through a collection of JSON-RPC methods. Given its compatibility with the Ethereum ecosystem, developers familiar with Ethereum's JSON-RPC APIs will find working with Berachain both intuitive and straightforward.
Getting Started Instructions
1. Choose a Package Manager (npm or yarn)
Your first step involves selecting a package manager, which will be crucial for managing your project's dependencies. The choice between npm
and yarn
depends on your personal preference or project requirements.
npm | yarn |
---|---|
Begin with npm by following the npm documentation. | For yarn , refer to yarn's installation guide. |
2. Set Up Your Project
To kickstart your project, open your terminal and execute the following commands:
mkdir berachain-api-quickstart
cd berachain-api-quickstart
npm init --yes
mkdir berachain-api-quickstart
cd berachain-api-quickstart
yarn init --yes
This creates a new directory named berachain-api-quickstart
and initializes a Node.js project within it.
3. Make Your First Request
For making API requests, we'll use Axios, a widely-used HTTP client. Install Axios with the following command:
npm install axios
# Or with yarn
# yarn add axios
Next, create an index.js
file in your project directory. Paste the following code to send a request to the Berachain network:
const axios = require('axios');
const url = `https://berachain-bartio.g.alchemy.com/v2/${yourAPIKey}`;
const payload = {
jsonrpc: '2.0',
id: 1,
method: 'eth_blockNumber',
params: []
};
axios.post(url, payload)
.then(response => {
console.log('Block Number:', response.data.result);
})
.catch(error => {
console.error(error);
});
Remember to replace yourAPIKey
with your actual Alchemy API key that you can get from your Alchemy dashboard.
4. Run Your Script
To execute your script and make a request to the Berachain App, run:
node index.js
You should see the current block number on Berachain App (in hexadecimal format) outputted to your console:
Block Number: 0x6d68e
Next Steps
Well done! You've just made your first request to the Berachain App API. With this foundation, you can dive deeper into the array of JSON-RPC methods available on Berachain App and start building your dApps on it!
