Wix Studio: Creating a Router

7 min read

Wix Studio is being released gradually to ensure a smooth onboarding experience. If you’re an agency or freelancer already using Wix or Editor X, you’ll receive an email once you have access.

Creating a router allows you to take complete control when handling certain incoming requests to your site.

This article takes you through the steps to add a router to your site, and what code you have to write in order to make your router work. To learn more about what a router is and why you would want to create one, see About Routers.

Add a Router

To add a router to your site:

Click the Pages icon to open the Site Pages panel.
Click the Add New Page icon . Then, click Add under Router.
Enter a URL prefix for your router and click Add & Edit Code to add the router to your site. All incoming requests with the specified URL prefix will be sent to your router for handling.

After you've added your router, the following occurs:

The following functions are added to your router.js file with sample code for a simple routing scenario:
- <your-router-prefix>_Router(request)
- <your-router-prefix>_SiteMap(sitemapRequest)
The router.js file is found in the src/backend folder of your backend code. Find your backend code by navigating to the Wix IDE from the Code panel. If you've integrated your site with Github, your backend code can be found in your local IDE.
Learn more about the router() and sitemap() functions.
A new section for router pages is created in the Pages panel for your routers. Router pages are grouped together under a title based on the URL prefixes used. For example, if your created a router with the prefix name "myRouter", a page named myRouter-page is added under the title MyRouter Pages (Router).

Sample Scenario

There are four parts to the sample code that's added to the routers.js file:

The import statement.
The sample data.
The router() function.
The sitemap() function.

Import statement

The functionality used to create a router is contained in the Router API. To use this functionality, you need to import it. By default, the ok() and notFound() functions are imported, as well as the WixRouterSitemapEntry object.

1import {ok, notFound, WixRouterSitemapEntry} from "wix-router";

If you want to use more of the functionality from the Router API, you need to add it to the import statement.

Sample Data

In the sample scenario, the router uses some static data contained in an object named peopleData.

1const peopleData = {  
2  "Ash": {    
3    title: "Ash Stowe",    
4    image: "https://static.wixstatic.com/media/b8f383e0fe2b478ea91362b707ef267b.jpg"  
5  },  
6  "Aiden": {    
7    title: "Aiden Johnson",    
8    image: "https://static.wixstatic.com/media/ca3c7ac5427e43928aa5f3f443ae2163.jpg"  
9  },  
10  "Jess": {    
11    title: "Jess White",    
12    image: "https://static.wixstatic.com/media/147fe6f37fe24e83977b4124e41b6d3d.jpg"  
13  },  
14  "Morgan": {    
15    title: "Morgan James",    
16    image: "https://static.wixstatic.com/media/59e1f2f4dbbc4f7c9d6e66e3e125d830.jpg"  
17  }
18};

The peopleData object contains four keys, each representing a person. Each person contains two properties, a title that is the person's full name and an image that is a link to an image of the person.

Although you can use static data with a router, typically you would use data from your site's database or an external source. We'll see where you would write code to retrieve that data a little later.

Regardless of where you get the data from, since you'll be writing the code that handles it, the data can be structured in any way you like.

Router Function

Remember, all incoming requests with the URL prefix you specified when creating the router are sent to your router for handling. The router() function is where you handle those requests.

The router() function is named with the following convention:

<router prefix>_Router(request)

So if you named your router myRouter, the code added to the routers.js file should look like:

myRouter_Router(request) { // routing code ...}

The router() function has a request parameter which receives a WixRouterRequest object that contains information about the incoming request. The object has information about the URL used to reach the router, where the request came from, and who the request came from.

Typically, the router() function will decide which page to show (if any) and what data to pass to the page. A response is then sent using the forbidden(), notFound(), ok(), redirect(), or sendStatus() functions.

Let's take a look at the sample router() function code:

1export function myRouter_Router(request) {
2
3  // Get item name from URL request
4  const name = request.path[0];
5
6  // Get the item data by name
7  const data = peopleData[name];
8
9  if (data) {
10
11    //define SEO tags 
12    const seoData = { 
13      title: data.title, 
14      description: `This is a description of ${data.title} page`,
15      noIndex: false,
16      metaTags: [
17         {
18          "property": "og:title",
19          "content": data.title,
20         },
21         {
22          "property": "og:image",
23          "content": data.image,
24         }
25      ]
26    };
27
28    // Render item page 
29    return ok("myRouter-page", data, seoData); 
30  }
31
32  // Return 404 if item is not found 
33  return notFound();
34}

The router() function begins by parsing the request's path to pull out a name value.

const name = request.path[0];

For example, a user might reach this router() function by browsing to https://mysite.com/myRouter/Ash. The received WixRouterRequest object's path property will be an array with one element: ["Ash"]. Now the value of name is "Ash".

Next, the router() function retrieves data based on the name it received.

const data = peopleData[name];

Continuing our example above, we pull out Ash's information from the peopleData object.

So data now holds:

1    { 
2      title: "Ash Stowe",
3      image: "https://static.wixstatic.com/media/b8f383e0fe2b478ea91362b707ef267b.jpg"
4    }

If you want to retrieve data from an external source, this is where you place the call to retrieve that data.

After attempting to retrieve the data that corresponds to the incoming request, we check to see if any data was found:

1    if (data) {
2      // ...
3    }

If nothing was found, the if is skipped and we return a 404 error using the notFound() function.

return notFound();

Assuming we found the data we were looking for, we now prepare some header data for our page:

1    const seoData = { 
2      title: data.title, 
3      description: `This is a description of ${data.title} page`,
4      noIndex: false,
5      metaTags: {
6        "og:title": data.title,
7        "og:image": data.image
8      }
9    };

Here we create a HeadOptions object that defines what will be put in the HTML head of the page we respond to the request with. That object is stored in the seoData variable.

The sample code creates a title and description based on the title property of the retrieved data object. It also sets noIndex to false, meaning search engines should index the page. Finally, some metaTags properties are added as well.

You can create the HeadOptions object using any information you want.

You can also add a keywords property to the HeadOptions object with a string containing the page's keywords.

Finally, we return a WixRouterResponse object using the ok() function:

return ok("myRouter-page", data, seoData);

Here we route the user to the router page named "myRouter-page" and pass it the data that was retrieved and the seoData that was built for the page.

Depending on the situation, you can return a number of different responses from the router() function. So far we've seen the notFound() and ok() functions in use. You can also use the forbidden() function to return a 403 response, the redirect() function to return a 301 or 302 response, or the sendStatus() function to return a response with any status code you choose.

Router Data

To use the data that was returned with a WixRouterResponse using the ok() function, use the wix-window-frontend getRouterData() function.

For example, we can take the data passed by the sample router code and use it to present a person's information on the myRouter-page page that was created.

First, we need to add a text and image element to serve as placeholders for a person's title and image.

Next, in the page's code we retrieve the router data and set the text and image elements to display the title and image from the data.

1import wixWindowFrontend from 'wix-window-frontend';
2
3$w.onReady(function () {
4  let data = wixWindowFrontend.getRouterData();
5  $w("#text1").text = data.title;
6  $w("#image1").src = data.image;
7});

If you preview the page, you'll see that the placeholders we put on the page are filled in with information from the data that was passed to the page. You can use the preview widget to see what the page looks like for any of the people in the peopleData object that was defined in the routers.js file.

The preview widget gets populated with the title values from the WixRouterSitemapEntry objects that are returned by the router's sitemap() function.

Sitemap Function

Like the router() function, the sitemap() function is named with the following convention:

<router prefix>_Sitemap(sitemapRequest)

So if you named your router myRouter, the code added to the routers.js file should look like:

myRouter_Sitemap(sitemapRequest) { // routing code ...}

The sitemap() function has a sitemapRequest parameter which receives a WixRouterSitemapEntry object that contains information about the incoming request. The object has information about the URL used to reach the router, the pages in the router, and who the request came from.

Typically, the sitemap() function creates a WixRouterSitemapEntry object for each item in the data used by the router. So, in our example, we create an entry for each person in the personData object. You also might want to include entries for other pages, like an index page or a search page.

Let's take a look at the sample sitemap() function code:

1export function myRouter_SiteMap(sitemapRequest) {
2
3  // Convert the data to site map entries
4  const siteMapEntries = Object.keys(peopleData).map( (name) => {
5    const data = peopleData[name];
6    const entry = new WixRouterSitemapEntry(name);
7    entry.pageName = "myRouter-page"; // The name of the page in the Wix Editor to render
8    entry.url = `/myRouter/${name}`; // Relative URL of the page
9    entry.title = data.title;   // For better SEO - Help Google
10    return entry;
11  } );
12
13  // Return the site map entries
14  return siteMapEntries;
15}

The sitemap() function takes the keys of the peopleData object and uses the JavaScript map() function to create an array of WixRouterSitemapEntry objects, one object for each key. Each entry is given values for the pageName, url, and title properties. Then the array is wrapped in a Promise and returned.

A sitemap entry can also contain changeFrequecy, lastModified, and priority properties to give search engines more information about each page.

In a case where you're using a router with external data, in the sitemap() function you would retrieve that data and build sitemap entries for each item that was retrieved.
