sortof

This module returns several functions that sort/filter a list of objects by date string. This module uses moment, so your date values can also be moment objects.

Given a list of objects that have a date value, you can filter by dates occuring:

• today
• tomorrow
• this week
• next week
• within a week (today + 1 week)
• this month
• next month
• within a month (today + 1 month)
• any range, given a start and end date

This module works in Node.js and the browser, with Browserify.

npm install sorta

usage

All functions take the same first 3 params:

• [Array] an array of objects
• [String] key in each object that points to the date string (ie. 'date', 'start_time')
• [String] format of date strings according to moment#format

Others take an additional param.
