开发者们，Wubba lubba dub dub！您是否想过通过网络开发的视角探索《瑞克和莫蒂》的广阔多元宇宙会是什么样子？好吧，拿起你的传送门枪并做好准备，因为今天我们将这样做 - 我们将使用 HTMX 和 Express.js 构建一个 Rick 和 Morty 角色资源管理器。本教程的目标是展示使用 HTMX 进行 Web 开发和实现分页是多么容易

设置 Express.js 服务器（我们的跨维度旅行设备）
使用 EJS 和 HTMX（我们的门户查看器）创建动态前端
使用 HTMX（我们在维度之间跳转的方法）实现平滑的服务器端分页

首先，确保安装了 Node.js。如果没有，您可以从nodejs.org 下载它。
接下来，我们将设置项目目录并安装必要的包。打开终端并运行以下命令：

项目结构：组织我们的项目类似于安排 Rick 的小工具。这是一个基本结构：

我们计算当前页面并检查是否有上一页或下一页。
每个链接上的 hx-get 属性告诉 HTMX 使用适当的页码和任何活动过滤器向我们的服务器发出 GET 请求。
hx-target="body" 确保导航时更新整个页面内容。
hx-push-url="true" 更新 URL，允许用户共享或为特定页面添加书签。

Crafting the Multiverse Filter

Let's take our interdimensional exploration to the next level by adding filters to our character explorer. Think of this as tuning into different channels on interdimensional cable – you want to find the right show (or character) amidst the multiverse chaos.

Add this filter section to your index.ejs file, right above the character table:

    
    
        All Statuses
        >Alive
        >Dead
        >Unknown
    
    Filter

These filters allow users to narrow down their search, just like Rick tuning his interdimensional cable to find the perfect show. Enhanced with the power HTMX, our filter implementation is powerful and intuitive, providing real-time updates without needing custom JavaScript. Our app with both filters and pagination should look like this:

Creating Character Profiles: Adding the Details Screen

Now that our Rick and Morty Character Explorer looks slick and functional, it's time to add another exciting feature: individual character profiles. Imagine diving into a detailed dossier on Morty or Rick, complete with all their vital stats and episode appearances. Let's add a "View More" button to our character table to take users to a detailed character profile page.

Let's add a new route to our server.js file:

// Route to display character details
app.get('/character/:id', async (req, res) => {
  const { id } = req.params;

  try {
    const response = await axios.get(`${BASE_URL}/${id}`);
    res.render('character', { character: response.data });
  } catch (error) {
    console.error('Error fetching character details:', error.message);
    res.status(500).render('error', { message: 'Error fetching character details' });
  }
});

Let's also add a new file views/character.ejs the necessary HTML for our character detail page:

    
    
    
    



    
<%= character.name %> - Details
    

        
        

            
Status: <%= character.status %>
            
Species: <%= character.species %>
            
Gender: <%= character.gender %>
            
Origin: <%= character.origin.name %>
            
Location: <%= character.location.name %>
        
        
Episodes
        

            <% character.episode.forEach(episode => { %>
                
Episode <%= episode.split('/').pop() %>
            <% }); %>
        
    
    Back to Character List

The code above defines a new route on our web server /character/:id. This new route is resolved when the user clicks on the view more option in the characters table. It fetches details for the specific character and returns a neatly rendered HTML page with all the character details. This page will look like this:

Putting It All Together: Your Interdimensional Character Explorer

Now that we've built our interdimensional travel device, it's time to see it in action. Here's a complete overview of our code, bringing together everything we've covered so far and also defining custom CSS styles to make the application look better.

Conclusion: Your Portal to Advanced Web Development

Congratulations—you've just built an interdimensional character explorer! In this adventure, we've covered a lot of ground, from setting up our Express.js server and designing a dynamic frontend with EJS and HTMX to implementing smooth pagination and filters.

This project is a testament to the power of HTMX. It shows how we can create dynamic, server-side rendered applications with minimal JavaScript. It's fast, efficient, and user-friendly—just like Rick's portal gun.

But don't stop here! There's a whole multiverse of possibilities waiting for you. Experiment with new features, add more filters or integrate additional APIs. The only limit is your imagination.

"Post-Credits Scene": Additional Resources and Easter Eggs

Before you go, here are some additional resources to help you on your journey:

• HTMX Documentation
• Express.js Documentation
• Rick and Morty API

And for those who made it to the end, here are a few hidden Rick and Morty references:

• Remember, "Wubba Lubba Dub Dub!" means you're in great pain, but also having a great time coding.
• Lastly, always be like Rick – curious, inventive, and never afraid to break the rules (of JavaScript).

Happy coding, and may your interdimensional travels be filled with endless possibilities!
