Sending Images from Server to EJS in Your Node.js Blog

Creating a blog with Node.js and Express can be a great way to learn the fundamentals of web development. One of the challenges you might face is how to serve images stored on your server and include them in your EJS templates. In this post, we’ll tackle that problem head-on and provide a clear, organized solution to help you display images correctly in your guides.

The Problem

You’ve successfully implemented the multer middleware to upload images to a folder on your server, but you’re struggling to pass the image file path to an EJS template for rendering. You’ve tried sending the filename but it hasn’t worked as intended, leaving you with an impractical solution.

Your current code could be simplified and made more effective for showing the images associated with your guides. So, let's break down how to resolve this concern!

The Solution

Step 1: Register a Static Folder

First and foremost, you need to inform Express about your static files (like images). By specifying a static folder, you can easily serve images directly from your server.

Add the following line to your Express app configuration:

This line tells Express to serve the files in the public/images directory, allowing you to access them using a straightforward URL structure.

Step 2: Build the Image Path in Your Controller

In your controller, while processing a post request, make sure to construct the correct image path based on your file uploads. Instead of passing just the filename, you can send the full URL path of the image to your EJS template.

Here’s how you can adjust your existing code:

Step 3: Render Images in Your EJS Template

Now that the image path is being passed as imageUrl, you can display it within your EJS template easily.

Here’s how you might add this in your posts.ejs file:

This piece of code dynamically inserts the image URL into the src attribute of the img tag, enabling the images from your server to be displayed properly within your guides.

Conclusion

By following these steps, you will successfully send image paths from your server to your EJS templates in a Node.js application. This solution enhances your blog by allowing you to display images alongside your posts seamlessly.

Embrace these techniques in your development process, and soon you'll find serving images and incorporating them into your web applications a straightforward task! Happy coding!
