Frontend System Design Essentials: Real-time updates

👉 Frontend System Design Essentials — Course (Now Available): https://icodeit.thinkific.com/courses... 👉 Frontend System Design Essentials — Book: https://leanpub.com/frontend-system-d... In this episode of *Frontend System Design Essentials**, we’re talking about **real-time updates* — how apps like Trello, Slack, or Google Docs stay in sync without needing manual refreshes or button clicks. I’ll show you exactly how I implemented *real-time card updates* in *Fellow**, a Trello-like app I’m building, using **Relay* and *GraphQL Subscriptions* — and walk you through everything you need to know as a frontend developer to do the same. You’ll learn: When real-time updates make sense (and when they don’t) How polling, WebSockets, and subscriptions compare — with examples How to implement subscriptions with Relay + GraphQL What to consider when scaling real-time systems And how this ties back to a previous video where we used polling (hint: it’s still valid — just a different tradeoff!) If you’re building collaborative tools, dashboards, or any UI where “what you see should always be fresh,” this episode will help you understand not just the *how**, but also the **why* of real-time design.
