feat: add WithProjectID for project-scoped telemetry - #5
Merged
Conversation
Add a WithProjectID option that attaches an X-Raindrop-Project-Id header
to every outbound request, routing events, signals, identify calls, and
traces to a named Raindrop project.
The slug is trimmed and validated against
^[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?$ once at New(). An unset or empty
value omits the header so the backend falls back to the org's default
project; an invalid value is ignored with a logged warning so a
misconfiguration never breaks ingestion.

Summary
Adds a
WithProjectIDoption that scopes all telemetry to a named Raindrop project. When set to a valid slug, the SDK attaches anX-Raindrop-Project-Idheader to every outbound request (events, signals, identify, traces, and the local Workshop mirror). When unset, no header is sent and the backend routes to the org's default project, so existing callers are unaffected.The slug is trimmed and validated once at
New()against^[a-z0-9](?:[a-z0-9-]{0,61}[a-z0-9])?$. An invalid value is ignored with a logged warning and no header is sent, so a misconfigured project id never breaks ingestion. This mirrors theprojectId/project_idsupport already in the JS and Python SDKs.Changes
