Wix Router Intro - Handling routes based on user and database content

What is a router?

When the user enters the URL in the browser, the browser forwards the URL data to the server(router) based on the URL the server sends the data back to the browser. In the case of Wix, we can create a router page with dragging and dropping elements and connect the element data based on the router data or we can redirect the User to 403 Page (Unauthorised) or 404 Page(Where there is no data found for that Url).

When you should use a router page?

Here are some cases when you need to use wix-router

Having a custom membership built with stripe and check the user is a premium member before redirecting to a premium page
Allow specific content to view in the database

e.g: Let say we have a list of article and if one of the articles is set to public (it should be view by all user). In this case, you will need to use a router to check if the article is public and based on that we can view the article or if it's not a public article, we can show a 403 Unauthorised page

Let's get started

In this tutorial, we are building an article page that can be view to the public only (if the article author is set to public).

There will be an Article database with a list of article titles, images, and a public column to store if the article can be view by the public or not. Instead of using a dynamic page. We are going to use a router page. So, we can override the permission, if the article is set to public and this is the safest way, as the article owner can only create, read, update, delete the article and we can also override the data only if the article data is set to public. Let's create a new blank site, and turn on the dev mode.

Create a new router page

Router Page is similar to dynamic page. you will design the page usually and add the element and connect the element via code. the data for that page will be passed from the router.

A popup will show as below, enter the router name and click on the "Add & Edit Code"

This will create a routers.js in the backend file

With 2 function

article_Router - So whenever someone goto Url "/article-page", this function will be trigger with the user detail and URL details and it should return either ok(), error page like notFound() or forbidden()
article_SiteMap - This function return an array of available pages to create a sitemap for SEO bot.

Before writing code in the routers.js, let's create a database(Collection).

Create a database

Let's create a new collection

Database name and permission

Set it can only view by article owner

Let's create a three column for simplicity

Sync the data to live database

Edit router.js code

URL : https://salman2301.wixsite.com/wix-router/{router page name}/{article title} E.g: https://salman2301.wixsite.com/wix-router/article/Do-more-in-less-time Do-more-in-less-time is the title of the article title, which we can get from the code and filter the database and view the page Every time if someone lands on the "/article" router will run the below logic

Let's breakdown the logic

Get the path name from the request URL
If the article name matches with the database name, return ok( )
Else return notFound( )

If the article is public
Show the page and handle SEO ( return ok( ) )
also add sitemap entry, for SEO bots to index the pages

If the article is not public
Check if the user who requested is the owner of the article, if it's true
Show the article ( return ok( ) )

Return forbidden( ); this will show the 403 Unauthorise page

Commented code

Check the comment explaining the code each line.


// import ok, notFound, forbidden page
// import WixRouterSitemapEntry allow use to create a sitemap
import {ok, notFound, forbidden,  WixRouterSitemapEntry } from "wix-router"; 
// import wixData to query the Article database
import wixData from "wix-data";

// This function will trigger, every time someone requested
// "/article" page
export async function article_Router(request) {
 // Get the path name /article/{path}
 const path = request.path[0];
 
 // If there is no path return 404 error page
 if(!path) return notFound();

 // replace the dash "-" with space " "
 const title = path.replace(/\-/g, " ");

 // Search for the title name on the Article Database
 // Set the Options to suppressAuth true
 // So, we can override the permission and view the article
 const data = await wixData.query("Article").eq("title" , title).limit(1).find({suppressAuth: true});

 if (data.length > 0) {
 // store the article data
 const article = data.items[0];
 
 
 if(article.public) {
 // create the SEO based on the article
 const seoData = { 
            title: article.title, 
            description: "This is a description of " + article.title + " page",
            noIndex: false,
            metaTags: {
 "og:title": article.title,
 "og:image": article.image
            }
          };

 // Show the item page and pass the data to frontend 
 return ok("article-page", article, seoData); 

      } else {
 // if the article is not public
 // check if the requested user id match with the article owner
 // if it match show the page
 if(request.user.id === article._owner) {
 // show the article
 // do not handle SEO
 return ok("article-page", article); 
        } else {
 // since the article is not public
 // and requested user is not the owner of the article
 // return 403 page
 return forbidden();
        } 
      }
   }

 // Return 404 if there is not article found for the title name
 return notFound();
}

// return array of sitemaps
// each sitemap contains title, url, pageName
export async function article_SiteMap(sitemapRequest) {
 // get the list of article which is set to public
 const articleData = await wixData.query("Article").eq("public", true).limit(999).find({suppressAuth: true});

 // loop through each article
 // generate array of site map
 const siteMapEntries = articleData.items.map(el =>{
 // get the article title and replace the space " " with dash "-"
 let { title } = el;
    title = title.replace(/\s/g , "-")

 // get the entry from WixRouterSitemapEntry and update the fields
 const entry = new WixRouterSitemapEntry(title);
    entry.pageName = title;  // The name of the page in the Wix editor to render
    entry.url = "/article/" + title ;   // Relative URL of the page
    entry.title = title;      // For better SEO - Help Google

 return entry;
  });
 
 return siteMapEntries;
}

Same code but less commented code


 import {ok, notFound,forbidden,  WixRouterSitemapEntry } from "wix-router"; 
import wixData from "wix-data";

export async function article_Router(request) {

 // Get item name from URL request
 const path = request.path[0];

 if(!path) return notFound();

 const title = path.replace(/\-/g, " ");

 // Get the item data by name
 const data = await wixData.query("Article").eq("title" , title).limit(1).find({suppressAuth: true});
   console.log({data, title});
 if (data.length > 0) {
 const article = data.items[0];
 if(article.public) {
 // Define SEO tags 
 const seoData = { 
            title: article.title, 
            description: "This is a description of " + article.title + " page",
            noIndex: false,
            metaTags: {
 "og:title": article.title,
 "og:image": article.image
            }
         };
         console.log("returning ok : " , article);
 // Render item page 
 return ok("article-page", article, seoData); 
      } else {
 if(request.user.id === article._owner) {
 return ok("article-page", article); 
         } else {
 return forbidden();
         } 
      }
   }

 // Return 404 if item is not found 
 return notFound();
}

export async function article_SiteMap(sitemapRequest) {
 
 const articleData = await wixData.query("Article").eq("public", true).limit(999).find({suppressAuth: true});

 const siteMapEntries = articleData.items.map(el =>{
 let { title } = el;
      title = title.replace(/\s/g , "-")

 const entry = new WixRouterSitemapEntry(title);
      entry.pageName = title;  // The name of the page in the Wix editor to render
      entry.url = "/article/" + title ;   // Relative URL of the page
      entry.title = title;      // For better SEO - Help Google
 return entry;
   });

 return siteMapEntries;
}

Edit the router page

Drag and drop the element in our case, we will drag the text element and the image element and let's write the page code to connect the element from the router data.


// page code

import wixWindow from 'wix-window'; 

$w.onReady(function () {
 // get the router data ok("page-name", routerData, seoData);
 let data = wixWindow.getRouterData();
 
 // map the data to the element
 $w('#textTitle').text = data.title;
 $w('#imageMain').src = data.image;
    $w("#imageMain").alt = data.title;
});

Site Monitoring

The router page runs only on the server. so the browser can't catch the logs. but there is a better way to check the logs, you can use site monitoring which is tool built by Wix to show all the realtime logs. The logs can be caught once you keep the site monitoring page open and then navigate to one of the article pages to trigger the logs.

The logs will be log out and you can click on to view more. to goto site monitoring.
