Codebold IT Solutions · WebSocket Development
Some features genuinely need a live connection — chat, live dashboards, notifications, collaborative editing. A WebSocket keeps one persistent connection open in both directions, instead of your frontend hammering an endpoint every few seconds hoping something changed.
— What you get
Scroll →
01
Server and client can both send messages any time over one open connection — no request-response round trip required.
02
Dropped connections reconnect automatically with backoff, and missed state gets resynced — not silently lost.
03
Messages routed to the right group of connected clients — a chat room, a dashboard, a specific document — not broadcast to everyone.
04
Backed by Redis pub/sub or a managed service so real-time state stays consistent across multiple server instances.
05
Where WebSockets aren't available — some corporate proxies still block them — we fall back to long-polling instead of just breaking.
— How a WebSocket connection stays open
01
01
The connection starts as a completely normal HTTP request with an Upgrade: websocket header — the server agrees, and that single request becomes a long-lived connection instead of closing after one response.
02
Unlike a typical request-response cycle, this connection doesn't close once data is sent — it stays open on both ends, ready to carry more messages at any moment, for as long as the page or the server keeps it alive.
03
Either side can send a message the instant it has something to say — the server can push a new chat message to the client without the client ever having to ask for it first.
04
If the connection drops — a network blip, a phone switching from WiFi to mobile data, a server restart — the client detects it immediately and reconnects with backoff, resyncing any state it missed in the gap.
— Why Codebold
Building software since 2013.
Not every 'live' feature needs a WebSocket — sometimes a short polling interval is genuinely simpler and good enough. We'll tell you which one your feature actually needs.
The WebSocket server lives alongside the REST or GraphQL API we build in Node.js or Python — one backend, not two systems to keep in sync.
Fixes, updates, and the next feature are part of the relationship — not a renegotiation every time something needs to change.
— Tech depth
— Good questions
If updates happen a few times a minute and a short delay is acceptable, polling is genuinely simpler and we'll say so. WebSockets earn their complexity when you need updates the instant they happen — chat, live cursors, real-time dashboards.
The client detects the drop, reconnects automatically with backoff, and resyncs any state it missed — nothing silently falls out of date.
Yes, with Redis pub/sub (or a managed real-time service) coordinating messages across every server instance, so it works the same whether you're running one server or ten.
Yes — the repository, the code, and everything in it are yours from day one.
We stay on. Fixes, updates, and the next feature are part of the relationship, not a separate negotiation.
A single real-time feature — live notifications, a chat panel — is usually a couple of weeks including the backend, reconnection handling, and testing under real network conditions.
