Experience
News Aggregator App
Chlanak is a news aggregator app built using Laravel (PHP, MySQL, Redis) and Vue.js. The app's basic idea is to provide users with news tailored to their interests from the most popular local news networks. The project was a two-person operation consisting of the client (the designer) and me (who owned back-end/front-end development and server deployment/maintenance).
Some of the more interesting aspects of the application include:
• Local database for IP address lookup: We needed the user's location to recommend specific popular categories in that region, and we were quite concerned with user privacy, so we opted for this solution.
Crawl data often and efficiently: We crawl data every three minutes to find the newest articles and use Socket.IO to inform our users as soon as we find them.
• Database optimizations: We get thousands of articles daily, so it was essential to have well-written queries to execute all our requests under 300ms.
• Front-end optimizations: the app is a PWA. We also split all the front-end code into chunks that are preloaded with a service worker, which helped us get a very respectable score on Google's PageSpeed Insights.
