1. 新建一个Public文件夹，里面包含css & js 文件夹，css里面放bootstrap.min.css，js里面放bootstrap.min.js & jquery.js
2. 在对应的ejs文件中添加依赖关系
<head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title> home </title> <link rel="stylesheet" href="/css/bootstrap.min.css"> <script src="/js/jquery.js"></script> <script src="/js/bootstrap.min.js"></script> </head>
3. 使用bootstrap的navbar，
href="/"分别都对应我们之前写好的/random, /cats, /r/:subreddit标签
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>
home
</title>
<link rel="stylesheet" href="/css/bootstrap.min.css">
<script src="/js/jquery.js"></script>
<script src="/js/bootstrap.min.js"></script>
</head>
<body>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav"
aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="/">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="/random">random</a>
</li>
<li class="nav-item">
<a class="nav-link" href="/r/soccer">soccer</a>
</li>
<li class="nav-item">
<a class="nav-link " href="/r/chickens" tabindex="-1" aria-disabled="true">chickens</a>
</li>
<li class="nav-item">
<a class="nav-link " href="/cats" tabindex="-1" aria-disabled="true">cats</a>
</li>
</ul>
</div>
</div>
</nav>
<div class="container">
<h1>Browsing the <%= name %> subreddit</h1>
<p>
<%= subscribers %> total subscribers
</p>
<hr>
<%for(let post of posts){%>
<article>
<p>
<%= post.title %> - <b>
<%=post.author%>
</b>>
</p>
<%if(post.img){%>
<img src=" <%= post.img %>" alt="">
<%}%>
</article>
<% }%>
</div>
</body>
</html>
div class = container,让整个内容居中显示一下。
4. index.js
const express = require('express');
const app = express();
const path = require('path');
const redditData = require('./data.json');
app.use(express.static(path.join(__dirname, 'public')))
// tell my app to use express, the teacher is ejs
// we don't need to require ejs, just set the engine view to ejs
app.set('view engine', 'ejs')
app.set('views', path.join(__dirname, '/views')) //__dirname is where index.js is located
app.get('/', (req, res) => {
res.render('home.ejs')
})
app.get('/random', (req, res) => {
const num = Math.floor(Math.random() * 10) + 1
res.render('random.ejs', { random: num })
})
// app.get('/r/:subreddit', (req, res) => {
// const { subreddit } = req.params;
// res.render('subreddit', { subreddit })
// })
app.get('/cats', (req, res) => {
const cats = ['sweety', 'candy', 'cutey', 'honey'];
res.render('cats.ejs', { cats })
})
app.get('/r/:subreddit', (req, res) => {
const { subreddit } = req.params;
const data = redditData[subreddit];
if (data) {
res.render('subreddit', { ...data });
} else {
res.render('notfound', { subreddit })
}
})
app.listen(3000, () => {
console.log("Listening On Port 3000")
})
