Why Media sharing in messages in HLD? - Purpose & Use Cases

The Big Idea

What if sharing your favorite moments in chat was as easy as sending a text?

The Scenario

Imagine trying to send photos and videos to your friends by manually attaching files every time in a chat app that was not designed for media. You have to upload each file separately, wait for it to finish, and then send a message with a link or description. It feels slow and clunky, especially when you want to share many files quickly.

The Problem

This manual method is slow because each file upload is separate and not optimized. It is error-prone since files can fail to upload or get lost. Users get frustrated waiting for uploads and managing links. The app can become unstable or crash with large files. Overall, it makes sharing media a painful experience.

The Solution

Media sharing in messages solves this by integrating file uploads directly into the messaging flow. It handles multiple files efficiently, shows upload progress, and stores media securely. Users can send images, videos, and audio seamlessly as part of their conversations. This makes sharing fast, reliable, and enjoyable.

Before vs After

✗ Before

uploadFile(file1);
uploadFile(file2);
sendMessage('See my photos');

✓ After

sendMessage({ text: 'See my photos', media: [file1, file2] });

What It Enables

It enables instant, rich conversations where users can express themselves beyond text by sharing memories and moments through media effortlessly.

Real Life Example

Think of WhatsApp or Messenger where you tap the attachment icon, select multiple photos, and send them all at once within the chat. The app shows thumbnails and upload progress, making sharing smooth and fun.
