Decentralized library

In this workshop, we'll explore how to create decentralized Library. We will use the pre-written Tron smart contract and deploy it using TronBox, we can deploy contract on any Testnet or Mainnet.

This dApp uses Nuxt, but is out of scope for this workshop, so don't worry, we will only be focusing on the pieces that helps us build. In practice, any JS framework can be used.

Please refer to the following steps to deploy this DApp on Nile testnet

1. NodeJS version 10 or 12

node -v
> v10.24.1

2. TronLink

Download TronLink chrome extension

3. TronBox

npm install -g tronbox 

4. Account

If there is no Tron account, please use TronLink to create a new Account. And then apply for some test coins of Nile testnet for testing. Please make sure the account has enough TRX. Get test coins

5. Template clone

Now we have Setup installed properly, let’s grab the dApp template that we will use as the skeleton of our dApp. This template is a website built using Nuxt.js (don't worry if you don't know Nuxt.js, we are not focusing on this part).

Clone the template into your folder:

git clone https://github.com/TRON-Developer-Hub/decentralized-library

cd decentralized-library

npm install

6. Modify the privatekey in tronbox.js

Paste your account's private key to 'privateKey' in tronbox.js

7. Smart Contract

Follow instructions to complete the smart contract code. If you only test the template code, please skip this step.

8. Deploy contract using TronBox

Compile contract:

tronbox compile

Deploy contract:

tronbox migrate --reset --network nile

On sucessfull deploy, copy the contract address

9. Paste your contract address to variable libraryContractAddress on line 5 in utils.js.

10. DApp code

Follow dapps to complete the DApp code. If you only test the template code, please skip this step.

11. Run DApp UI

cd dapp-ui
npm install
npm run dev

12. Navigate to http://localhost:3000/ to see the app running.

decentralized-library's Issues

[TronLink] We recommend that DApp developers use tronLink.request({method: 'tron_requestAccounts'})

Hi! How i can change it will be right? Where can i change it?

[TronLink] We recommend that DApp developers use tronLink.request({method: 'tron_requestAccounts'}) to request users’ account information at the earliest time possible in order to get a complete TronWeb injection and to ensure proper connection of your DApp to TronLink extension wallet.

I have file walletConnector.js but it empty almost:

import WalletConnect from '@walletconnect/browser'
import WalletConnectQRCodeModal from '@walletconnect/qrcode-modal'

let walletConnector = null
let accountAddress = null

export const initWalletConnect = () => {
  // Create a walletConnector


  // Check if connection is already established

  // Subscribe to Events

}


export async function sampleTx() {
  // Draft transaction

  // Send transaction
 
}

why we cant to login Tronlink?

I use the readme.md step by step to start the project,but i can't to login the TronLink, how deploy contract to localhost?or anyway easy develop for localhost?

migration aborted

When try to migrate, via command: tronbox migrate --reset --network nile

Get error:

Using network 'nile'.

Running migration: 1_initial_migration.js
  Deploying Migrations...
ERROR: aborted

I've already create wallet account, and set the private key in tronbox.js, and get 2000 TRX for nile test network.

Any idea?

struct Book { string name; string description; bool valid; // false if been borrowed uint256 price; // TRX per day address owner; // owner of the book }
