Navigation Wars: Top or Side?

I've made quite a few apps the past years. A social network for travel, local activities directory (kind of like Foursquare but for activivites), a word game, a screenshot and bookmarking tool, a design curation, data driven color palettes, a CRM for small businesses. Well. I think you get it.

Optimizing large table rendering in React

I recently had an issue working on Wobaka.com where the contacts table were taking too long time to re-render. What happened was that when more than 100 contacts were rendered, the UI felt laggy and sometimes froze when changing filters (free text, lead status, etc). I wasn't happy with

Sentry with User Context for Express

Today I tried to add some user context to Klart.io's issue tracking. This is helpful since it allows you to track which users get what errors. Klart's backend is based on Node and Express so naturally this will target those technologies. My first atempt was to use the default

Testing Express Apps with Mocha, Chai and Puppeteer
