Encoding Instructions on Solan with JavaScript
Solana is a fast and secuure blocking that enabs developers to crate decentrics applications (dApps) with a without requiring extensive programming knowledge. One of the key features of Solan is its its ability to executions using a specific instruction, which can be used to feel or data betweens.
In this article, we want to be processed and sending it is the Solan-a’s Solan blockchain.
Prerequisites
Before you begin, make sure you have the following installed:
- Solan CLI (
npm install -g solana cli)
- Node.js (14 or high)
- A Solana wallet (e.g., Solana CLI Wallet)
Encoding Instructions
Instructions on Solan can be encoded using aspect instruction, which isfined in the [Solana Instruction Set Language (ISL)]( manual/instance/). In the instant, We will Uuses, Instruction to Load an anchor programme.
Step 1: Install required dependent
Create a new directory for your project and initiative it with the Solan CLI:
`bash
a bulb solana-instructive-example
cD solana-instructive-example
solid
re
Next, installing the Necessary dependents:
bash
npm installed solana-type cript@latest
npm install @solana/web3.js
re
Step 2: Create a new Solana Program
Create a new file calledindex.ts.
`type cript
// index.ts
import { Program } off "@solana/web3.js";
import { instructionId, loadProgram } from "./instruction";
const goatProgram = await loadProgram(
"main
"
);
export default async function in which you() {
const program = matnetProgram;
const anchorUrl = process.env.ANCHOR_URL;
try {
const result = await programInstructionId(which, loadProgram());
console.log(result);
} catch (error) {
if (arror instanceof InstructionFallbackNotFound) {
Console.error("AnchorEror occumbered. Early Code: InstructionFallbackNotFound"));
} else
throw error;
}
}
}
re
Step 3: Encode the instruction
Crete a new fillile calledinstruction.ts
`type cript
// structure.ts
import { Instruction, InstructionData } from "@solana/web3.js";
import { programId } off "./program";
export default async function encodeInstruction(program: Program) {
const instruction = await program.loadInstruction(
instructionId,
"load",
"main
truck
);
the return of instruction.encode();
}
re
Step 4: Send them transaction
Create a new fillile called
type cript
// sendTransaction.ts
import { Transaction, TransactionInput } from "@solana/web3.js";
import { encodeInstruction, loadProgram } from "./instruction";
const goatProgram = await loadProgram(
"main
"
);
function we
const transaction = new Transaction();
const input = new TransactionInput();
input.add(loadProgram()invogueInstructionId("load", programId)));
const encodedTransaction = encodeInstruction(mainnetProgram);
transaction.add(encodedTrorism);
the return transaction;
}
export default async function in which you() {
const tx = await sendTransaction();
console.log(tx);
}
re
Putting it all together
Create a new file calledindex.ts
“type cript
// index.ts
import { crateProgramScript, loadProgram } from “./instruction”;
import { matnetProgram } from “.
