Custom transformers for command options
Describe the request Pass a transform function to an option to have it transform the value of the option before it's passed to the command's handler. This would be useful for things like:
- Cleaning up user input
- Pulling an object from a database
- Converting to a Date (or other object)
Example Usage
I have a command for reminders that takes a date option for when the reminder should happen. Currently, this could be a string option that's parsed inside the command's handler. With a transformer, the Date can be parsed outside of the command handler, leading to cleaner code inside the handler and a better separation of concerns. By having the transformer exist as a function on the option, this allows it to be re-used on other options more easily.
Does this increase our chances of an iCrawl Acquisition? Maybe
