Highlight, a company focused on ensuring fast and efficient user experiences, has successfully implemented data compression techniques to improve the speed and efficiency of their web application. By leveraging compression algorithms, particularly Google's Brotli, which is known for its superior performance over the more traditional Gzip, Highlight has significantly reduced the size of data payloads sent over their GraphQL endpoints. This reduction has resulted in decreased bandwidth usage and faster response times without increased latency. Brotli's widespread support across modern browsers allows Highlight to enhance performance easily, with a fallback to Gzip when necessary. The company uses the Go programming language to implement Brotli compression in their applications, demonstrating the practical and straightforward nature of incorporating these compression techniques into various web stacks.
