How to Create Node JS Routes by Slug Instead of ID

In the world of web development, generating user-friendly URLs is an essential practice for improving user experience and SEO. One common question that arises among developers is, "How do you make a Node JS route by slug instead of ID?" If you're working on a NodeJS blog, particularly with a MEAN stack architecture, understanding how to leverage slugs can significantly enhance your application's routing system.

The Problem: Accessing Resources Using Slugs

For your blog application, you aim to allow users to access resources (like articles or posts) using slugs as part of the URL instead of the default ID. This shift can create more meaningful and memorable links, such as https://yourblog.com/resources/my-awe... rather than https://yourblog.com/resources/12345.

Your initial route that fetches resources by ID looks like this:

However, you're looking to replace the ID-based lookup with slug-based routing.

The Solution: Updating Your Route to Use Slugs

To implement the slug-based route, you'll need to make a few key changes in your route definition. Here's how to do it step-by-step:

Step 1: Update the Route Definition

Instead of findById, you'll use findOne to search for a resource by its slug. This modified route should look like:

Step 2: Understand findOne

The method findOne is used here instead of findById.

You need to specify the condition as slug: req.params.slug.

This ensures your application looks for a resource with a matching slug string.

Step 3: Schema Considerations

Your Mongoose schema already has a slug field defined:

To ensure that the slug searches are efficient, consider indexing the slug field. MongoDB will use indexes to optimize search speeds, so adding an index to the slug field is beneficial, especially as your database grows.

Step 4: Handling Errors

While testing your new slug route, ensure you prepare for potential issues:

Slug Not Found: If the slug does not exist in the database, you might want to handle this gracefully. Consider redirecting to a 404 page or showing a friendly message.

Database Connection: Always check for connectivity issues when querying the database.

Conclusion

Using slugs instead of IDs in your Node JS application not only makes your URLs cleaner but also enhances the overall user experience. By simply updating the route to utilize findOne with slugs, you can effectively change how resources are accessed in your MEAN stack blog.

By following the steps outlined in this post, implementing slug-based routing should now be seamless for your Node JS application.

Happy coding!
