Basic CRUD app

This is an example of an on-chain CRUD dapp. This example is a journal dapp where you can create, read, update, and delete journal entries on the solana blockchain and interact with the solana program via a UI.

Test it out here: solana-journal-eight.vercel.app

This project was created using the create-solana-dapp generator.

Getting Started

Prerequisites

• Node v18.18.0 or higher
• Rust v1.70.0 or higher
• Anchor CLI 0.29.0 or higher
• Solana CLI 1.17.0 or higher

Installation

Clone repo

git clone <repo-url>
cd <repo-name>

Install dependencies

npm install

Start the web app

npm run dev

Apps

Anchor

This is a Solana program written in Rust using the Anchor framework.

Note: The solana program code for the journal dapp can be found in anchor/programs/src/lib.rs

Commands

You can use any normal anchor commands. Either move to the anchor directory and run the anchor command or prefix the command with npm run, eg: npm run anchor.

Sync the program id:

Running this command will create a new keypair in the anchor/target/deploy directory and save the address to the Anchor config file and update the declare_id! macro in the ./src/lib.rs file of the program.

You will manually need to update the constant in anchor/lib/counter-exports.ts to match the new program id.

npm run anchor keys sync

Build the program:

npm run anchor-build

Start the test validator with the program deployed:

npm run anchor-localnet

Run the tests

npm run anchor-test

Deploy to Devnet

npm run anchor deploy --provider.cluster devnet

Web

This is a React app that uses the Anchor generated client to interact with the Solana program.

Commands

Start the web app

npm run dev

Build the web app

npm run build
