Solana: Setting up Web3 environment locally

Here is a step by step to set the web3 environment locally on Windows:

Prerequisites

Node.js (or higher) is installed on Windows

Code editor or chosen here (such as Visual Studio Code, Intellij Idea)

A local blockchain Discovery (such as Infura, Metamask)

Step 1: Install a web3 wallet and directory

Go to [web3.js documentation] ( and download the web3.js. The latest version.

Select the “Electron” package that allows you to perform a web3 wallet in a native application.

Step 2: Set the electron on Windows

Install node.js from the official website if you didn’t.

Download and install the electron [here] (

Follow the installation instructions for the electronic version.

Step 3: Install web3.js and Blockchain Explorer Local

Solana: Setting up Web3 environment locally

Execute npm installs web3 on the terminal to install web3.js.

Install a local blockchain explorer like Infura or Metamask. In this example, we will use itar.

Step 4: Set the local web3 environment

Create a new folder for your project and find it.

Perform to create the npm init a 'pack.json file".




Install the necessary addictions including "Web3", "Infura" and "Etheter".



Initializes the new Ethereum portfolio using broken.


 Step 5: Web3 configuration.js

Create a new JavaScript file (such asWeb3.js) in the project folder.

Opens the “Web3” directory and initializes with the help of local blockchain expoller.

`Javascript



Const Web3 = necessary ('Web3');

Const Infuraclient = New Web3 (New URL ('WSS: //mainnet.infura.io/v3/your_project_id'));

// Put the Ethereum portfolio here

Const Web3 = New Web3 (Infuraclient);



 Step 6: Insert the first intelligent contract

Create a new JavaScript file (asMyconttract.js) to write the first intelligent contract.




Opens the "Web3" directory and initializes with the help of local blockchain expoller.

Javascript



Const Web3 = necessary ('Web3');

Const Infuraclient = New Web3 (New URL ('WSS: //mainnet.infura.io/v3/your_project_id'));

// Put the Ethereum portfolio here

Const Web3 = New Web3 (Infuraclient);



 Step 7: turn and perform the intelligent contract 


Use a device like "truffle" to fill in an intelligent contract.



Execute the contract completed with the following command:

Bash

The NPX truffle performs myconttract.js



This assembles the contract, transfers it to the Ethereum network and installs it in the blockchain.

 Example code 

Here are some exemplary codes for departure:

Javascript



// Web3.js

Const Web3 = necessary ('Web3');

Const Infuraclient = New Web3 (New URL ('WSS: //mainnet.infura.io/v3/your_project_id'));

// Put the Ethereum portfolio here

Const Web3 = New Web3 (Infuraclient);

Module.exports = {{{

  Contract: "Myconttract",

  ABI: [...], // determines the inhabitant of the Treaty

};

Javascript



// Myconttract.js

Const Web3 = necessary ('Web3');

Const Infuraclient = New Web3 (New URL ('WSS: //mainnet.infura.io/v3/your_project_id'));

// Put the Ethereum portfolio here

Const Web3 = New Web3 (Infuraclient);

Module.exports = {{{

  Sender: "0xyour_address",

  A: "0xmyConttratCTDdress",

  Value: 100,

};

Tips and variants

Use another local blockchain explorer such as Metamask or Polkadot.

Use other Ethereum portfolios such as Metamask or Metawallet.

Fill out an intelligent contract with a device like truffle or webpack.

Install the intelligent contract with Mainnet using a tool such as truffle or remix.

I hope this helps you set the web3 environment locally at Windows!
