Solana: How to create and edit LookUp Tables in the new 2.0.0 version of web3.js?

Create and Edit search tables web3.js 2.0.0: Step -by -step instructions

As web3.JS continues to develop with new versions, it is not uncommon for developers to meet changes in the underlying protocol and application subscriptions. In this article, we are in the new version of Web3.JS.

What is the replacement table?

The reference chart is the interface for a block chain address or data survey. You can complete the SOKU bases based on certain criteria such as address, signature or information. In connection with web3.JS, sustainable tables are used for various applications, such as decentralized financing (defi), non-sponge cod (NFT) and others.

Use the old way: Address Looking for Program '

Before 2.0.0, you can create and edit search tables with an old address of the "API:

Javascript

Const looking = new web3.eth.

// The configuration of the shipping board

});

// Create a function for the table in the Table

Function survey () {

Return to look for.query (address);

}

// add address to the action

survey (). Then ((result) => {

Console.log (result);

});

`

However, this approach had some restrictions. The Osdetlooktable Programs application subscription is not designed for large stations for applications or complex queries.

As a result of the release of web3.js 2.0.0, a new interface was introduced to create and edit search tables: loutpuptable.createadedit. This method offers more flexibility and scalability compared to the old application subscription:

`Javascript

Const looks like it = waiting for the search.creeteandede ({{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{

// The composition of a replacement table (eg address list)

Addresses,

});

// Create a function for the table in the Table

Asynkrical function survey () {

Const Result = Waiting to search.

Return result;

}

// add address to the action

survey (). Then ((result) => {

Console.log (result);

});

`

The “Createdadet” method takes care of creating and managing several tables, including determining the standard values ​​of the table or combining existing tables.

How does Lokupabelle work

To understand how the search tables work in the new version of Web3.JS, we immerse yourself in your internal work. Here’s a high overview:

• Creating a table

  : If you create a new table loulpeebles.createeanded, web3.js will create a table directory based on the configuration.

• Index Information

  

  : The data is marked by storing in a separate storage system (eg JSON or database).

• Information Questionnaire : If the survey is conducted, web3.js will search for directory information to use the relevant information.

Research

In this article, we explore how to create and edit search tables into a new version of web3.js using the "Lookuplees.creatEdeedit" method. By using this improved user interface, you can now perform more complex queries and easily manage large data records.

Be sure to check the official [web3.js documentation] ( for more information on the search tables and related topics.

Example Code

Here is an example of "lookingables.createadedit" to create a new table:

Javascript

Const looks like it = waiting for the search.creeteandede ({{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{

Addresses: [

‘0x …’,

‘0x …’,

] ,,

});

// Create a function for the table in the Table

Asynkrical function survey () {

Const Result = Waiting to search.

Return result;

}

// add address to the action

survey (). Then ((result) => {

Console.log (result);

});

`

This code creates a new search table with two addresses and shows how to ask it with the “Createaded” method.
