If you need help creating your regex pattern, we recommend using RegExr.

Not all features from RegExr are supported in our library, see table above.

Getting Started

This library uses a simple api. The string to match is given in target, and the regex to match with is set in pattern. These are set in the storage, regex:api/match

To run the match, run function regex:api/match.


data modify storage regex:api/match target set value "Hello, World!"
data modify storage regex:api/match pattern set value "[A-Za-z]+"
function regex:api/match
  success: 1b,
  output: ["H","e","l","l","o"]
