@parcel/diagnostic provides a standardized way to handle diagnostics (errors, warnings, hints) within the Parcel ecosystem. It defines a consistent data structure for representing diagnostic messages, including details like file path, source location, message severity, and suggested actions. This uniformity simplifies error reporting and allows Parcel tooling to present diagnostic information in a user-friendly and consistent manner across different build processes and integrations. It also facilitates machine-parseable output for IDEs and other tools.
The @parcel/diagnostic package had frequent releases from late 2021 through 2023, with a peak in early 2022. Release frequency decreased in 2024, with a notable absence of releases for several months. 2025 saw a resurgence in March, followed by further releases in May and June, then no releases in the last three months (July, August, September).
