URL formats for sharing via social networks

Why?

With the rise of social platforms like Facebook, Twitter and LinkedIn, it's easier than ever to share URLs with a large audience quickly and efficiently. However, each social network has its own unique way of handling URLs, and understanding the correct formatting can make a significant difference in the visibility and engagement of your shared content.

Facebook

`https://www.facebook.com/sharer.php?u=${url}`;

This format allows you to share a specific URL with your Facebook friends and followers. By replacing url with the actual URL, you can create a link that shows a dialog with the content you want to share.

Messenger

Sharing via Messenger is another way to share a URL with your Facebook friends and contacts.

`https://www.facebook.com/dialog/send?app_id=${appId}&display=popup&link=${url}&redirect_uri=${url}`;

To use this format, you'll need to replace ${appId} with your Facebook app ID and ${url} with the URL you want to share.

Follow this documentation to create a Facebook app and get the app ID.

Zalo

To share a URL via Zalo, a widely used messaging app in Vietnam, you need to create a JSON object containing a key of "url" and the value of the URL you want to share. Then stringify and encode the string in the base64 format.

function encodeB64(str: string) {
  return window.btoa(str)
}

const sharingUrl = `https://button-share.zalo.me/share_external?d=${encodeB64(JSON.stringify({ url }))}`
