Create a Solana RPC Connection with Typescript/Javascript Using @Solana/Web3.js *
Solana RPC sacrifices Several Methods of Interacting with the Network, Allowing You To Read and Write Data From Different Sources. In this article, we will show how to create a connection to the solana network using @solana/web3.js, a popular javascript library for interaction with the solana blockchain.
Prerequisites
Before you start, make sure you have:
- Developer of Solana and Creating A Local Development Environment (EG Web3.JS, Truffle Suite).
2.
- Meeting Typescript and JavaScript.
Step 1: Create A New Project
Create A New Folder for Your Project and Initialize It Using NPM:
`Bash
MKDIR SOLANA-RPC-Example
CD Solana-RPC-Example
NPM Init -y
Step 2: Install @solana/web3.js *
Install the Required Package:
`Bash
NPM install @solana/web3.js
Step 3: Create A New Typescript/JavaScript File
Create A New File Named Index.ts And Add the Following Code to Set Up The Solana Web3 Provider Link:
`TypeScript
Import {web3} by '@solana/web3.js';
Import {config} from './config.json'; // Loading Configuration
Const web3 = New Web3 (Config.web3url);
Default web3 export;
Step 4: Configure the RPC Link
Create A Config.json File with the Following Content:
`Json
{
"rpcurl": " // replace with your solana rpc url
"Keypath": "/DEV/0", // Replace with your personal key (if you use a pair key)
"Network": {
"ID": 1, // ID or the Solana Network (Eg Mainnet)
"Label": "MAINNET" // Network Label
}
}
Step 5: Set the link
Change your file Index.ts to set up the link:
`TypeScript
Import {web3} by '@solana/web3.js';
Import {config} from './config.json';
Const web3 = New Web3 (Config.web3url);
Export const rpcconnection = web3.connect ();
Step 6: Test The Link
Use rpconnection to test your relationship. You can use the following code examples:
`TypeScript
// Get the Current Balance on a particular account
Rpconnection accounts.get ('your account');
// Send Data to Solana Using Web3 API
Const TX = {
Data: {
// Submission Data to Solana (EG Transaction Script)
},
// Other Options ...
};
Rpconnection.sendransction (TX);
Full sample code
Here’s the full example code:
`TypeScript
Import {web3} by '@solana/web3.js';
Import {config} from './config.json';
Const web3 = New Web3 (Config.web3url);
Default web3 export;
Import {
accounts,
send
} by '../transction'; // Replace With Your Transaction File
// Set the link
Const rpcconnection = web3.connect ();
// Test The Link
rpconnection.accounts.get ('your account');
That’s it! You already have a working RPC Connection Solana Using @Solana/Web3.js in Typescript/JavaScript.
Note that this is just the first step. In order to interact with the network, you will need to create and manage accounts, send transactions and retrieve data from your application. See the official documentation @Solana/Web3.js for More Information on the Construction of Stable Applications on the Solana Network.
