Range project

[jdbruijn]

npm package @vidavidorra/range.

I ran into this while working on the platform scripts for device list. I wanted to have a CLI argument that can be used to specify the minimum or maximum measurement interval, but don't particularly like multiple arguments for that. I thought using a range, like semver, would be very nice there. After thinking about it, not only for numbers, but also for dates and perhaps other types.
It'd be useful if this also provides a Joi extension, but not yet sure if that would best be in the same package or in a separate package as @vidavidorra/joi-extension-range. I'm leaning towards the latter, for better visibility to the public.

This would be strongly based on semver's ranges. I want to be able to use similar syntax for for number and Date items, where I can write filter strings like >=600, >20 <=80, <2020-03-01 and >=2020-01-01 <2020-02-10.

It should support:

• Dates, using Moment.js;
• Numbers;
• Strings (not sure about this yet).

It should have comparators:

• < less than;
• <= less than or equal to;
• = equal;
• >= greater than or equal to;
• > greater than.

Without a comparator, = would be assumed.
