- it’s more fun
- you can take advantage of Dart’s support for static type checking
- you can make use of Dart’s isolates (think F# mailbox or Erlang processes, isolates is Dart’s implementation of Carl Hewitt’s actor model) to abstract over making concurrent requests and handling retries, etc.
- it’s more fun!
Update 05/07/2014 : I had previously stated that raven-js had dependencies on jQuery, ember, etc. that was incorrect. As they were in fact raven-js plugins for those frameworks (as stated in its Plugins documentation page here) and the raven-js itself doesn’t have any dependencies.
Operational params can be used to customize the behaviour of captureMessage and captureException, such as adding tags, or other metadata to go along with the events.
Following the official guidelines on writing a Sentry client, the library supports:
- DSN configuration via constructor argument
- null means disabled
- Graceful failure handling
- fallback to logging to console when Sentry is disabled
- retry on error (except for HTTP status codes 400, 401, 403, and 503)
- configurable max no. of retries
- exponential delay when retrying
- temporarily disable if Sentry is unavailable (503)
- Support for tagging
- common tags can be provided in the client constructor
- additional tags are supplied for each event
- when common and event-specific tags overlap, both are sent as part of the event
- Non-blocking event submission
- events are sent to available isolates in round-robin fashion, whom then process them asynchronously and concurrently
- configurable level of concurrency per core which determines number of isolates running at the same time
- Basic data sanitization/scrubbing
- credit card number-like fields are scrubbed
- Sentry key and secrets are scrubbed
- Values that look like passwords or secrets are scrubbed
