socket.io only
Use lodash for array manipulation (chunk, flatten, groupBy, uniq), object utilities (cloneDeep, merge, pick, omit), function helpers (debounce, throttle, memoize), and collection operations. Import only the functions you need (import groupBy from 'lodash/groupBy') to keep bundle size down.
Use Socket.IO for chat applications, live collaboration, real-time dashboards, multiplayer games, or any feature where the server needs to push updates to clients. The automatic reconnection and room system make it production-ready out of the box.
Modern JavaScript (ES2020+) has absorbed many lodash features natively: Array.flat(), Object.fromEntries(), optional chaining, nullish coalescing. Audit what you actually need before adding lodash — you may already have it in the language.
Socket.IO's abstraction layer adds overhead — if you're communicating between services where you control both ends, raw WebSockets or Server-Sent Events (for one-way) are lighter. For very high throughput (millions of concurrent connections), the overhead of Socket.IO's protocol becomes meaningful.
