Here’s an article on how to get a ‘web version’ with ether:
Networkversion “Getting Ethers.js: Step -by -step guide
When building a decentralized application (DAPP) with Ether.JS, one of the essential information you need is the web version. In this article, we will go through the process to get the ‘web version’ using Ethers.js.
What is Ethers.js and the online version?
Ethers.js is a popular JavaScript library for the construction of Ethereum-based applications, including DAP. It provides a simple way to interact with the Ethereum block chain. The online version refers to the current state of the network, including block number, gas threshold and other relevant information.
Step 1: Ethers.js Import **
First bring your Ether.js Library JavaScript:
`Javascript
Import {ether} ‘ether’;
`
Step 2: Example of Ethereum Service Provider
Create an example of an Ethereum service provider that uses eether.providers.web3:const web3 = new eetters.providers.web3 ();
Step 3: Getting a web version
To get the web version, you can use the following code:
`Javascript
Web3.eth.net.
`
This returns a string indicating the current network version. For example:
`
0x4e1b5d5a4c34 …
`
Step 4: Checking online errors
Networkversion 'can throw an error if there is a problem with the Ethereum service provider or network connection. To check the errors using the following code:
Javascript
web3.eth.net.status ();
if (web3eth.net.status ()! == ‘connected’) {
Console.error (‘online error:’, web3.eth.net.status ());
}
`
Step 5: Getting a block number
You can also get the current block number to make sure it is a valid web version:
`Javascript
Const blocknumbber = wait Ethers.Getlatestblocknumbber ();
Console.log (blocknumbber);
`
Infanting everything
Here is an example of a code end that shows how ether.JS uses the web version and check errors:
`Javascript
Import {ether} ‘ether’;
Async function Main () {
Try {
Const Web3 = New Ethers.Providers.web3 ();
// Get a web version
Const Networkversion = Wait Web3.eth.net.
Console.log (Online version: $ {Networkversion});
// Check online errors
if (web3eth.net.status ()! == ‘connected’) {
Console.error (‘online error:’, web3.eth.net.status ());
}
} catch (error) {
Console.error (error);
}
}
Main ();
`
In this example, we create a web3 service provider expression and get the web version using `eether.providers.web3 (). Eth.net. We then check if the network is connected and log in to errors that may occur.
By following these steps, you can easily get DAPP’s online version using Ethers.JS. Be sure to always deal with errors and exceptions in the production code correctly.
