Developer Offshore guide
Keep a slow WebSocket client from exhausting the server
A field guide for real-time product teams broadcasting frequent updates. It uses a narrow test, one troublesome case, and a handoff a reviewer can replay.

Keep a slow WebSocket client from exhausting the server
- Write down how you will decide how much unsent data one connection may retain.
- Retain buffer size, send latency, dropped messages, connection state, and memory use.
- Test the awkward case where a backgrounded browser stops reading while the server keeps publishing.
Start with the disputed behavior
This job fits real-time product teams broadcasting frequent updates. Before touching code, write the behavior under review: decide how much unsent data one connection may retain. Include the repository revision, environment, representative fixture, reviewer, and a clear stop point.
Record a plain baseline
Run one ordinary case first and save buffer size, send latency, dropped messages, connection state, and memory use. Keep the input small enough that another developer can inspect it without special production access. The baseline tells you whether the test setup itself is trustworthy.
Review record
Scroll sideways to read every column on a small screen.
| Moment | Evidence | Owner |
|---|---|---|
| Baseline | buffer size, send latency, dropped messages, connection state, and memory use | Assigned developer |
| Boundary case | a backgrounded browser stops reading while the server keeps publishing | Developer and reviewer |
| Release | Test result, limits, and rollback note | Internal release owner |
Recreate the case people tend to miss
The useful stress case is simple to state: a backgrounded browser stops reading while the server keeps publishing. Change only one condition at a time. Note the request or event, prior state, observed transition, final state, and the clock used for every timestamp.
Put the correction beside the failure
Trace the result to the narrowest responsible boundary. Put the regression check close to that boundary, make the smallest defensible correction, and rerun both the ordinary and troublesome cases. Record nearby behavior that remains outside the brief.
Keep authority with the system owner
An offshore developer may prepare fixtures, investigate the failure, implement a reviewed patch, and collect proof. Internal owners retain protected credentials, architecture exceptions, irreversible data work, incident disclosure, and the production release decision.
Write a handoff that survives a time-zone change
The handoff should name the starting and ending revisions, changed files, fixture data, commands, passed and skipped checks, remaining uncertainty, rollback approach, and reviewer. It should answer the original question about how to decide how much unsent data one connection may retain.
Questions about assessing Philippine developers
Can an offshore developer own this check?
Yes. Give the developer synthetic data, scoped access, a fixed revision, and a named reviewer.
Who accepts the production risk?
The internal system owner reviews the evidence and approves or rejects the release.
