DevFrame uses structured diagnostics to surface actionable warnings and errors at runtime. Each diagnostic has a unique error code, a human-readable message, and a link back to this documentation.
- Codes follow the pattern
DF+ 4-digit number (e.g.,DF0001). - Every error page includes the cause, recommended fix, and a reference to the source file that emits it.
- The diagnostics system is powered by
logs-sdk, which provides structured logging with docs URLs, ANSI-formatted console output, and level-based filtering.
Emitted by devframe — framework-neutral host / shared-state / auth surface.
