Here is a step -by -step guide for setting up a web3 environment locally on the Windows car:
Premise
- Node.JS (14.x or larger) installed on your Windows car
- A code editor or IDE of your choice (eg Visual Studio code, Intellij Idea)
- A local blockchain (eg, infura, metamark) explorer
Step 1: Install a wallet and web library3
- Go to the Documentation [Web3.JS] ( and download the latest web3.js.
- Choose the “Electron
package, which will allow you to run the web3 wallet in a native application.
Step 2: Set up your electron on Windows
- Install Node.JS on the official site if you haven't done it already.
- Download and install the electron from [here] (
- Follow the installation instructions for your electron version.
Step 3: Install Web3.JS and a local blockchain explorer
- RunNPM Install Web3
in your terminal to install web3.js.
- Install a local blockchain explorer such as Infura or Metask. For this example, we will use Infura.
Step 4: Configure Local Web3 environment3
- Create a new folder for your project and sail in it.
- Runnpm initiate to create a package file.
- Install the necessary addictions, including
web3
,infura-client and
ethers’.
- Initialize a new Ethereum wallet using Infura.
Step 5: Configure Web3.JS
- Create a new JavaScript file (for example,
Web3.js
) in the project folder.
- Import the
Web3
library and initialize it with the local blockchain explorer.
`Javascript
const web3 = requires (‘web3’);
Const Infuraclient = New Web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));
// configure -va Ethereum wallet here
const web3 = new web3 (infuclient);
`
Step 6: Write -Do first intelligent contract
- Create a new JavaScript file (eg
MyContract.Js
) to write your first intelligent contract.
- Import the
Web3
library and initialize it with the local blockchain explorer.
`Javascript
const web3 = requires (‘web3’);
Const Infuraclient = New Web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));
// configure -va Ethereum wallet here
const web3 = new web3 (infuclient);
`
Step 7: Compare and run the intelligent contract
- Use an instrument like “truffle to compile your intelligent contract.
- Roll the compiled contract using the following command:
`Bash
npx trufe runs mycontract.js
This will compile your contract, migrate it to the Ethereum network and implement it in blockchain.
Code for example
Here are some examples of code to start:
`Javascript
// web3.js
const web3 = requires (‘web3’);
Const Infuraclient = New Web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));
// configure -va Ethereum wallet here
const web3 = new web3 (infuclient);
module.exports = {
Contract: “MyContract”,
Abi: […], // define the abi of your contract.
};
`
`Javascript
// mycontract.js
const web3 = requires (‘web3’);
Const Infuraclient = New Web3 (new URL (‘wss: //mainnet.infura.io/v3/your_project_id’));
// configure -va Ethereum wallet here
const web3 = new web3 (infuclient);
module.exports = {
From: ‘0xyour_address’,
to: ‘0xmycontractddres’,
Value: 100,
};
`
Tips and Variations
- Use another local blockchain local explorer, such as Metask or Polkadot.
- Use a different Ethereum wallet, such as Metask or Metawallet.
- Compare the intelligent contract using a tool like truffle or webpack.
- Implement the intelligent Mainnet contract using a tool like Truffle or Remix.
I hope this will help you set up a local web3 medium on your Windows car!
