Why noise kills useful diffs
API responses constantly change createdAt, requestId, and traceId between calls. Diffing two responses without filtering them shows hundreds of meaningless changes. Ignoring volatile keys reduces the diff to the values that actually represent business changes.
Configuring ignored keys
Add keys by name (createdAt) or by JSON Pointer (/data/items/*/timestamp). Wildcards in pointers let you ignore the same field at every depth. Patterns are case-sensitive by default.
Common ignore lists
REST APIs: createdAt, updatedAt, requestId, traceId, etag, x-amz-request-id. GraphQL: __typename, cursor. Kubernetes: resourceVersion, uid, managedFields, generation, creationTimestamp.
// Ignore list
[
"createdAt",
"updatedAt",
"requestId",
"/data/items/*/etag"
]Persisting your config
Ignore lists are stored locally in your browser so they survive page reloads. Export them as JSON if you want to share them with the rest of the team or check them into a repo.
Privacy
Filter rules and JSON content stay in your browser. No upload, no telemetry.
