Solana Web3.js: Understanding the Evolution of V1 and V2
As a developer building a Solana-based dapp with Nextjs, React, and Solana/web3.js, you are probably aware that there have been significant changes to the library recently. Two major changes stand out: Solana/web3.js v1 is no longer actively supported, and v2 has recently entered development.
Why did the changes happen?
In 2020, Solana’s web3.js was released under an open source license, allowing for community support and improvements. However, in July 2021, Solana announced the transition to a new, actively supported version of its library: v2.
The main reason for this change is the growing popularity and adoption of Nextjs as a frontend framework. As a result, there has been increasing attention paid to optimizing the web3.js API for seamless integration with Nextjs. Solana/web3.js v1, being old and not actively supported, cannot meet the requirements of a large-scale application like yours.
Solana/web3.js v1: what to expect
To give you a better idea of what to expect in Solana/web3.js v1:
: The current version has security vulnerabilities that need to be fixed before it can be considered stable.
Solana/web3.js v2: what will happen?
As Solana announces that v2 is actively supported and has begun to roll out, you can expect a number of exciting features. These include:
Conclusion
When choosing between Solana/web3.js v1 and v2, consider the specific needs of your project. While v1 is still actively supported, its security vulnerabilities may not be an issue for all projects. However, if you need the latest features and performance capabilities, v2 is what you need. With this knowledge, you can make an informed decision when choosing the best version of Solana/web3.js for your Nextjs application.
Code Example
To give you an idea of how Solana/web3.js handles different versions, here is a simple example:
import { Web3 } from 'solana-web3';
const web3 = new Web3(new Web3.providers.HttpProvider('
In v2, the API will look like this:
import { Web3 } from '@solana/web3.js';
import '@solana/web3.js/4.7.0';
const web3 = new Web3({
providers: [
{
url: '
},
],
});
This example demonstrates how you can switch between the two versions depending on your project’s needs.
Additional Tips
By following these steps, you will be on your way to successfully integrating Solana/web3.js with Nextjs and React into your dapp.
