Frequently Asked Questions
What breaks SSE streams?
Missing double-newline terminators, wrong Content-Type (must be text/event-stream), and buffering proxies. The formatter flags all three.
Retry field meaning?
Millisecond reconnection delay the client honors after drops. Set 3000 for normal feeds; higher for expensive reconnects.
SSE vs WebSockets?
SSE for server→client streams (simpler, auto-reconnect); WebSockets for bidirectional. One-way dashboards belong on SSE.
Is stream data uploaded?
No — formatting runs locally in your browser. Streams never leave your device.
