** Create Solana RPC connection using Typescript/JavaScript using @solana/web3.js's ...
Solana RPC offers many ways to interact with the network, allowing the data to read and write data from different sources. In this article, we will show you how to connect with the Solana network using "@Solana/Web3.js" with a popular JavaScript bookstore to interact with Solana Blockchain.
Prerequisites
Before starting, make sure you have:
1
2
- Knowledge of Typescript and JavaScript.
Step 1: Create a new project
Create a new folder for the project and initialize it using NPM:
Bash
Mkir Solana-RPC example
Solana-RPC-Example CD
Npm init -y
`
** Step 2: Install@solana/web3.jsss
Install the requested package:
`Bash
NPM Install @Solana/Web3.js
`
Step 3: Create a new Typescript/JavaScript
file
Create a new file calledindex.ts’ and add the following code to set the connection to the only web3 provider:
`dictiloscript
{Web3} imports from the '@@ Solana/Web3.js' site;
Import {config} from './config.json'; // charge configuration
Const web3 = new web3 (Confi.web3url);
Export the default web;
Step 4: Configure the RPC connection
Create aconf.jsonwith the following content file:
Json
{{
“Rpcurl”: ” // Replace Solana RPC URL
“Keypath”: “/dev/0”, // replace the private key (if you use a couple of keys)
“Net”: {
“ID”: 1, // the ID of the Solana Network (eg MainNet)
“Tag”: “mainnet” // label for network
}
}
`
Step 5: Set the connection
Change “index.ts” to set the connection:
dictiloscript
{Web3} imports from the '@@ Solana/Web3.js' site;
Import {config} from './config.json';
Const web3 = new web3 (Confi.web3url);
Export Const Rpcconnection = Web3.Connect ();
Step 6: Test contact
Userpcconnectionis to test the connection. The following examples can be used:
`dictiloscript
// Get the current balance of that account
Rpcconnection accounts.get ('self-account');
// Sending data to Solana using Web3 API
CONST TX = {
Data: {
// data to be sent to Solana (such as a transaction script)
},
// other options ...
};
Rpcconnection.sendtransection (TX);
Full example code
Here is the full example code:
dictiloscript
{Web3} imports from the '@@ Solana/Web3.js' site;
Import {config} from './config.json';
Const web3 = new web3 (Confi.web3url);
Export the default web;
Affairs {
Accounts,
Delegation
} from '../transections'; // Replace with the transaction file
// Set the connection
Const rpcconnection = web3.connect ();
// test the relationship
rpcconnection.accounts.get ('tautlcil');
That's it! Now you have a working Solana RPC connection using@Solana/Web3.js” in Typescript/JavaScript.
Note that this is only the first step. To interact with the network, you need to create and manage accounts, send transactions and reset data from the application. For more information on the Solana network, see the official documentation of `@Solana/Web3.js” for the creation of robust applications.
