React.js & Express.js Mobile App - NFT Crypter

Getting Started

Prerequisites

To run this project, you need to have Node.js installed on your machine. You can download and install Node.js from here.

Installation

  1. Clone the repository:
git clone https://github.com/enndylove/React-MobileApp_Crypter.git
  1. Navigate to the project directory:
cd React-MobileApp_Crypter
  1. Install the required dependencies:
npm install
  1. Building project (also need to enter this command after making changes in the jsx files)
npm run build

Prisma ORM commands with clear all information in database

  1. Prisma init: Initializes Prisma in your project.
npx prisma init
  1. Generate Prisma Client: Generates the Prisma Client.
npx prisma generate
  1. Migrate Prisma Dev: Applies the migrations to your database.
npx prisma migrate dev

Environment

  1. Create a file named .env and add the following code:
# Get YOUR_MORALIS_API_KEY from "https://admin.moralis.io/settings#api_keys"
REACT_APP_MORALIS=YOUR_MORALIS_API_KEY

# Get YOUR_WALLETCONNECT_PROJECT_ID from "https://cloud.walletconnect.com/app/project"
REACT_APP_WALLETCONNECT=YOUR_WALLETCONNECT_PROJECT_ID

# Set YOUR_NAME, default "Connect Crypter"
REACT_APP_WALLETCONNECT_NAME="YOUR_NAME"

# Set YOUR_DESCRIPTION, default "Connect Crypter login walletConnect"
REACT_APP_WALLETCONNECT_DESCRIPTION="YOUR_DESCRIPTION"

# Set YOUR_URL, default "https://localhost:5000/"
REACT_APP_WALLETCONNECT_URL="YOUR_URL"

# Set YOUR_ICON, default ["https://avatars.githubusercontent.com/u/37784886"]
REACT_APP_WALLETCONNECT_ICONS=["YOUR_ICON"]

# Set YOUR_PORT, example: 5000
REACT_APP_PORT=YOUR_PORT
My .env example:
REACT_APP_MORALIS=my_moralis_api_key
REACT_APP_WALLETCONNECT=my_walletconnect_project_id
REACT_APP_WALLETCONNECT_URL="https://localhost:5000/"
DATABASE_URL="file:./dev.db"

Run the project

npm start
or
node server.js

        console.log("Moralis started successfully");
    } catch (error) {
        console.error("Moralis is started:");
    }
};
startMoralis();

Moralis API Data in Header.jsx file:

const responseAddress = await Moralis.EvmApi.wallets.getWalletActiveChains({
    address: address,
});

const chain = responseAddress.raw.active_chains[0]?.chain,
    chainId = responseAddress.raw.active_chains[0]?.chain_id,
    defaultParams = {
        address: address,
        chain: chainId,
}

const balance = await Moralis.EvmApi.balance.getNativeBalance({
    address: address,
    chain: chainId,
});

const name = await Moralis.EvmApi.resolve.resolveAddress({
    address: address,
});

const resp = await Moralis.EvmApi.nft.getWalletNFTs({
    address: address,
    chain: chainId,
});

const formattedBalance = parseFloat(balance.raw.balance) / 10 ** 18

const walletName = name?.raw?.name || `${chain}_${chainId}`

const walletTagName = `@${name?.raw?.name || chain + chainId}`

const clipAddress = `${address.substring(0, 6)}...${address.slice(-4)}`

const whatStatus = resp.raw ? resp.raw.status : "NO SYNCED"

const formaterClip = formattedBalance.toFixed(2)

const usdtBalance = (formaterClip * 2229).toFixed(2)

Example post to server:

await fetch("/api/profile", {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
    },
    body: JSON.stringify({
        walletAddress,
        walletBalance,
        walletUSDTBalance,
        walletName,
        walletTagName,
        walletStatus,
        walletAddressClip
    }),
});

Example get data from server:

try {
    const request = await fetch("/api/profile", {
        method: "GET",
        headers: {
            "Content-Type": "application/json",
        },
    });
    
    if (!request.ok || !request.ok) {
        throw new Error("Network response was not ok");
    }
    
    const data = await request.json();
    
    console.log(
        walletAddress,
        walletBalance,
        walletUSDTBalance,
        walletName,
        walletTagName,
        walletStatus,
        walletAddressClip

} catch (error) {
