How To Get Stack Overflow SEO Friendly URL Structure In Nuxt.js?

- 1 answer

Stack Overflow has the following URL structure stackoverflow.com/questions/{question ID}/{question title}, and if you misstype the {question title} you will be permanently redirected 301 to the correct URL as long as you have the correct {question ID}.

Assuming that I have both the id and the slug, how can I make the same URL structure that Stack Overflow has in Nuxt.js with SSR?

Edit: Apprently the URL structure is known as Clean URL.

I have tried using a fully dynamic URLs with pages/x/_.vue, but that gives me a "new" page for each request and does not give a 301 redirect.

This post suggest the following: /questions/8811192/question-title could be rewritten to /mywebsite.php?id=8811192&convention=questions. So if I can interpret /qeustions/{id}/{title} as just /qeustions/{id} I could be halfway there I guess.

The following works for me, but I am not sure if it's the exact same as how the Stack Overflow URL structure works.

I am using async asyncData to get content from the database, and as you can access context and redirect, req and res as parameters you can perform a 301 redirect.

First I am using unknown dynamic nested routes in my folder like this /pages/folder/_.vue. Which will catch all routes including domain.com/folder/{id} and domain.com/folder/{id}/{title}.

To get the ID of in the requested url you can split the pathMatch and get the first element, like this params.pathMatch.split('/')[0].

Then I use the id to get the content from the database, which is Strapi in my case. Like this await $strapi.findOne('contentType', id).

After that we can create the actual URL we want like this /folder/${data.id}/${data.slug}. Note: the data.slug culd be replaced with the data.title which could be converted to a URL friendly string.

Finally we can match the user requested URL with the actual URL of the content if(route.fullPath !== actualURL), and if the requested url is not the same we can performe a redirect with redirect(301, actualURL).

My entire code:

async asyncData({ redirect, req, route, app, $strapi, errg.

Finally we can match the user requested URL with the actual URL of the content if(route.fullPath !== actualURL), and if the requested url is not the same we can performe a redirect with redirect(301, actualURL).

My entire code:

async asyncData({ redirect, req, route, app, $strapi, error, params }) {
    try {
        const recipeID = params.pathMatch.split('/')[0];
        const matchingRecipe = await $strapi.findOne('recipes', recipeID);
        const correctPath = `${app.localePath('recipes')}/${matchingRecipe.id}/${matchingRecipe.slug}`;
        if(route.fullPath !== correctPath) {
            console.log(`Redirect: ${route.fullPath} => ${correctPath}`);
            redirect(301, correctPath);
        }
        return {
            recipe: matchingRecipe
        }
    } catch(e) {
        console.log(e)
        error({ statusCode: e.statusCode, message: e.original });
    }
    
},
