added in 0.7.0
Tools to help debug interceptor chain execution.
debug-observer
(debug-observer)(debug-observer options)Returns an observer function that logs, at debug level, the interceptor name, stage, execution id, and a description of context changes.
The context changes are in the form of a map. The :added key is a map of key path to added values. The :removed key is a map of key path to removed values. The :changed key is a map of key path to a value change, a map of :from and :to.
Options map:
| Key | Type | Description |
|---|---|---|
| :omit | set or function | Identifies key paths, as vectors, to omit in the description. |
| :changes-only? | boolean | If true, then log only when the context changes. |
| :tap? | boolean | If true, the data is sent to tap> rather than logged. |
The :omit option is used to prevent certain key paths from appearing in the result delta; the value for these is replaced with .... It is typically a set, but can also be a function that accepts a key path vector. It is commonly used to omit large, insecure values such as [:response :body].
