Anchor CRUD Dapp

This is a on-chain CRUD dapp. It lets you create, read, update and delete entries on the solana blockchain and interact with the solana program via a UI.

Debug

1. Deactivate features in Solana test validator

solana-test-validator --deactivate-feature <FEATURE_TO_DEACTIVATE_ID> --bpf-program <PROGRAM_ID>  target/deploy/anchor_dapp.so --reset

2. Solana: Computational budget exceeded

• Logs contain - 810 of 810 compute units utilised
• Can be done inside the program/frontend as well using increase compute budget instructions for that txn.

solana-test-validator --compute-unit-limit 500000     // can put value here - 500000 is an example

Commands

• Anchor

anchor keys sync
anchor build
anchor deploy

• React

npm run dev

• Solana test validator

solana-test-validator --compute-unit-limit 500000

• To check program account pubkey or balance

solana-keygen pubkey target/deploy/anchor_dapp-keypair.json
solana balance $(solana-keygen pubkey target/deploy/anchor_dapp-keypair.json)

Apps

anchor

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

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
