| Command | Description |
|---|---|
| encodeURIComponent() | encodes a URI component by substituting one, two, or three escape sequences that correspond to the character's UTF-8 encoding for each occurrence of a certain character. |
| window.open() | permits the sharing of links on WhatsApp Web by opening a new browser window or tab with the provided URL. |
| express.static() | serves static files to the client, allowing them to be accessed by HTML, CSS, and JavaScript, from the provided directory. |
| res.redirect() | Redirects the client to the provided URL by sending them a redirect response; this is helpful for redirecting to the WhatsApp Web share link. |
| app.use() | serves static files by mounting middleware functions to the Express application in this example. |
| app.get() | creates an endpoint for the WhatsApp Web share link by defining a route handler for GET queries. |

Enabling Cross-Platform WhatsApp Sharing Capabilities
The first script creates share buttons for WhatsApp's online and mobile versions by utilizing HTML and JavaScript. The mobile share button's href attribute opens WhatsApp on mobile devices with a pre-filled message by using the whatsapp://send?text= URL scheme. A button with the id of "shareButton" is made for the desktop version. This button now has a onclick event listener added by the script. When it is clicked, https://web.whatsapp.com/send?text= is used to create the URL for WhatsApp Web. and uses encodeURIComponent to encrypt the message. window is then used to open the created URL in a new browser tab.open, enabling WhatsApp Web users to distribute the message.
The second script uses Node.js and HTML for both frontend and backend development. The Express framework is used by the Node.js backend script to configure a server. The server defines a route /share that reroutes to the WhatsApp Web share URL with a pre-filled message and delivers static files from the "public" directory. Share buttons for the web and mobile are generated by the frontend script. The same whatsapp://send?text= URL scheme is used by the mobile button. The /share endpoint on the server is linked to by the web share button. When this endpoint is reached, the user is sent to WhatsApp Web with the encoded message using res.redirect, enabling WhatsApp Web sharing.

Using Share Buttons in WhatsApp to Improve User Experience
The user experience on various devices is an essential factor to take into account when putting WhatsApp share buttons into place. When interacting, mobile users behave differently from desktop users. As a result, it's vital to guarantee that both platforms' sharing features operate flawlessly. Users want rapid and fast activities when using mobile devices. Direct communication with the WhatsApp app is made possible by the usage of the whatsapp://send?text= URL scheme, which offers a quick and simple sharing experience.
Replicating this smooth experience on a PC is a challenge. Not only must the WhatsApp Web interface be accessed, but it also needs to be made sure the message is prepared and prepared for sending. This calls for cautious URL handling and correct message encoding with encodeURIComponent. Furthermore, desktop users might find it useful to have the share button easily accessible and visible, which can be accomplished by carefully planning the button's layout and positioning on the page. You can develop a sharing function that is easy to use and increases engagement on all devices by taking care of these minor details.
