加密货币如今风靡一时，随着可用硬币的数量过多，有一个工具可以轻松搜索和查看它们的详细信息是至关重要的。 Crypto Finder 应用程序就是这样做的。该应用程序使用 React 构建，为用户搜索、过滤和查看加密货币详细信息提供无缝体验。
Crypto Finder 应用程序包括：
以下是项目结构的快速概述：
要开始使用 Crypto Finder 应用程序，请按照以下步骤操作：
git clone https://github.com/abhishekgurjar-in/Crypto-Finder cd crypto-finder
npm install
npm start
App.js 组件设置路由并包含导航栏和页脚组件。
import React from "react";
import CryptoFinder from "./components/CryptoFinder";
import "./App.css";
import Navbar from "./components/Navbar";
import Footer from "./components/Footer";
import {Route,Routes} from "react-router-dom"
import CryptoDetails from "./components/CryptoDetails";
const App = () => {
return (
<div>
<Navbar />
<Routes>
<Route path="/" element={<CryptoFinder/>}/>
<Route path="/details/:id" element={<CryptoDetails/>}/>
</Routes>
<Footer />
</div>
);
};
export default App;
CryptoFinder.js 组件处理获取和显示加密货币列表。它包括一个用于过滤结果的搜索栏。
import React, { useEffect, useState } from "react";
import axios from "axios";
import { Link } from "react-router-dom";
const CryptoFinder = () => {
const [search, setSearch] = useState("");
const [crypto, setCrypto] = useState([]);
const [filteredCrypto, setFilteredCrypto] = useState([]);
useEffect(() => {
axios
.get(`https://api.coingecko.com/api/v3/coins/markets`, {
params: {
vs_currency: "inr",
order: "market_cap_desc",
per_page: 100,
page: 1,
sparkline: false,
},
})
.then((res) => {
setCrypto(res.data);
setFilteredCrypto(res.data);
});
}, []);
const handleSearch = () => {
const filteredData = crypto.filter((data) => {
return data.name.toLowerCase().includes(search.toLowerCase());
});
setFilteredCrypto(filteredData);
};
if (crypto.length === 0) {
return (
<div className="loader-box">
<div className="loader"></div>
</div>
);
}
return (
<div className="crypto-finder">
<div className="input-box">
<input
type="text"
value={search}
onChange={(e) => setSearch(e.target.value)}
onKeyDown={handleSearch}
placeholder="Search for a cryptocurrency"
/>
<button onClick={handleSearch}>Search</button>
</div>
<div className="cards">
{filteredCrypto.map((val, id) => (
<div className="card" key={id}>
<img src={val.image} alt={val.name} />
<h1>{val.name}</h1>
<h4>{val.symbol.toUpperCase()}</h4>
<h4>₹{val.current_price.toFixed(2)}</h4>
<Link to={`/details/${val.id}`}>
<button>View Details</button>
</Link>
</div>
))}
</div>
</div>
);
};
export default CryptoFinder;
CryptoDetails.js 组件获取并显示有关所选加密货币的详细信息。
import React, { useEffect, useState } from "react";
import axios from "axios";
import { useParams } from "react-router-dom";
const CryptoDetails = () => {
const { id } = useParams();
const [cryptoDetails, setCryptoDetails] = useState(null);
useEffect(() => {
axios
.get(`https://api.coingecko.com/api/v3/coins/${id}`, {
params: {
localization: false,
},
})
.then((res) => {
setCryptoDetails(res.data);
});
}, [id]);
if (!cryptoDetails) {
return (
<div className="loader-box">
<div className="loader"></div>
</div>
);
}
return (
<div className="crypto-details">
<div className="basic-details-image-box">
<div className="basic-details">
<h1>{cryptoDetails.name}</h1>
<h4>{cryptoDetails.symbol.toUpperCase()}</h4>
<h4>
Current Price: ₹
{cryptoDetails.market_data.current_price.inr.toFixed(2)}
</h4>
</div>
<div className="image-box">
<img src={cryptoDetails.image.large} alt={cryptoDetails.name} />
</div>
</div>
<div className="detail-desc">
<h3>Description :</h3>
<p >{cryptoDetails.description.en}</p>
</div>
<div className="market-and-additional">
<div className="market-data">
<h2>Market Data</h2>
<p>
<b>Market Cap: </b>₹
{cryptoDetails.market_data.market_cap.inr.toLocaleString()}

</p>
<p><b>24h High:</b> ₹{cryptoDetails.market_data.high_24h.inr}</p>

</div>
</div>
);
};
export default CryptoDetails;
Navbar.js 组件为应用程序提供标题。
import React from 'react'
const Navbar = () => {
return (
<div className="navbar">
<h1>Crypto Finder</h1>
</div>
)
}
export default Navbar
Footer.js 组件为应用程序提供页脚。
import React from 'react'
const Footer = () => {
return (
<div className="footer">
<p>Made with ❤️ by Abhishek Gurjar</p>
</div>
)
}
export default Footer
