A small CLI utility to sample REST apis every given interval.

Synopsis: node sample -u <rest-api-url>

Samples the provided every 5000 millis, emits outputs to console, and saves them also in ./results.txt.

We had a wierd proxi / cache problem we needed to investigate, where users reported that they get different responses form same services, who should be in fact static.

This utility samples them, and performs a diff of every response against it's previous, and emits descriptive warnings if a difference is found, including text-diffs and all :)

• colorful output to the screen
• output is saved in hourly rotating log file

Synopsis: node sample -u <url> [options]

Samples the provided url every 5000 millis, emits outputs to console, and saves them also in ./results.txt

Options:

  -u, --url        the url to sample               [required]
  -i, --interval   interval of sampling            [default: 5000]
  -l, --log-level  default log level for the tool  [default: "INFO"]
  -o, --output     output file of results          [default: "results.txt"]

NOTE if you want to sample few URLs - currenlty, you can run few processes, and direct the results of every URL to a different file.

npm install rest-sampler
