Solana: How to encode an instruction and send transaction to an anchor based program using javascript
Coding Instructions for Solana with JavaScript
Solana is a quick and secure blockchain platform that allows developers to create decentralized applications (DAPPs) without requiring extensive programming knowledge. One of the main features of Solana is its ability to do transactions through a certain instruction that can be used to send funds or data between accounts.
In this article, we will look at the instruction coding process and send it to anchor based on JavaScript at Blockchain Solana.
Prerequisite
Before you start, make sure you are installed as follows:
- Solana Cli (
NPM installation -G Solana -Cli
)
- NODE.JS (14 or higher)
- Solar purse (eg Solar Wallet Cli)
Coding Instructions
Solana instructions can be encoded using a special instruction that is defined in the [bench instruction kit language (ISL)] ( In this example, we will use the “load” instruction to upload an anchor program.
Step 1: Install the necessary addictions
Create a new director of your project and initialize it with Solana Cli:
`Bash
MKDir Solana-Stroke Sample
CD Solana-Stone Example
Solana Init
Install the necessary addictions below:
Bash
NPM Install Solana-TypesCript@Last
NPM Installation @Solar/Web3.js
Step 2: Create a new Solana program
Create a new file calledIndex.ts’ and add the next code to create a new anchor program:
`TypesCript
// index.ts
Import {program} from “@Solana/Web3.Js”;
Import {instructions, program load} from “./instression”;
Const Mainnet program = Wait for loading (
“Mainnet”,
“
);
Export to default ASYNC MAIN () {
Const Program = Mainnet program;
CONST ANCHORRL = Process.env.Anchor_url;
Try {
Const score = wait for the Destructide program (main, Loadprogram ());
Console.log (result);
} Catch (error) {
If (immediate instrument error
Consoles.Error (“Anchorerror appeared. Error code: backup instructions”);
} else {
Throwing error;
}
}
}
`
Step 3: Codify Instructions
Create a new file called "Instructions.ts" and add this code to encode the instruction:
TypesCript
// Instructions.ts
Import {instructions, instructions} “@solar/web3.js”;
Import {programid} from “./program”;
Export default ASYNC Code Function (Program: Program) {
CON INSTRIERI = Waiting Program.Loadistruction (
Instructions for instructions,
“Load”,
“Mainnet”,
true
);
Instructions for return.encode ();
}
`
Step 4: Send a deal
Create a new file called "Sendtranstion.ts" and add this code to send the transaction:
TypesCript
// Sendtranstion.ts
Import {transaction, transactioninput} from “@solar/web3.Js”;
Import {codeinstression, Loadprogram} from “./instression”;
Const Mainnet program = Wait for loading (
“Mainnet”,
“
);
SendtransCtion Function () {
Const deal = new transaction ();
Const input = New TransactionInput ();
input.Add (LOAD PROGRAGE ().
Const CodedTransCtion = Coding (Mainnet Program);
Transaction.Add (CodeCtion);
return transaction;
}
Export to default ASYNC MAIN () {
Const TX = Gaids Sendtranstion ();
Console.log (TX);
}
`
all by putting together
Create a new file called “Index.ts” and add the next code to collect and run an example:
TypesCript
// index.ts
Import {CREATEPROPROP, LOADFRIGNS} from “./instression”;
Import {mainnet program} from “.
