dependabit / monitor/src / URLContentChecker

Class: URLContentChecker

Defined in: packages/monitor/src/checkers/url-content.ts:10

Contract for all dependency checker implementations.

Remarks

The Monitor selects a checker based on AccessConfig.accessMethod and calls fetch followed by compare. Plugins implement this interface to extend the set of supported access methods.

Use When

Implementing a custom checker for a new access method (e.g., a proprietary API or registry). Register it with Monitor.registerChecker.

Never

• fetch should throw only for unrecoverable errors (network failure, auth error). Temporary 5xx responses should be retried inside the implementation to avoid marking the dependency as errored.
• compare receives the stored previous snapshot and the live current snapshot. Do not assume both snapshots were produced by the same checker version.

• Checker
