React Native BlurHash

Description

Blurred Image Placeholders

Overview

BlurHash provides a compact placeholder representation for images, enhancing the user’s loading experience.

How It Works

1. Generate: On your server, convert each image into a short string (20–30 characters) that encodes a blurred preview.
2. Store: Keep this string alongside the original image URL in your database or storage system.
3. Transmit: When delivering data to the client, include both the image URL and its corresponding BlurHash string.
4. Render: The client decodes the BlurHash string into a low‑resolution blurred image, which is displayed while the full image loads.

Benefits

• Eliminates unsightly gray boxes during loading.
• The concise string easily fits into common data formats such as JSON fields.
