Strict Dates and ES Module Support

Major Features and Breaking changes in this version

Improvements

• Valid date parsing - By default fecha will check validity of dates. Previously 2019-55-01 or 2019-01-42 would parse correctly, since Javascript can handle it. Now invalid dates will return null instead
• ES Module and Tree Shaking Support - You can now import fecha parse or format independently

import {format, parse} from 'fecha';

format(...);
parse(...)

Breaking changes

• parseDate may return null when previously returned a Date. See improvements above, but invalid dates will return null now
• Change to how to set masks and i18n
  Previously

import fecha from 'fecha';

fecha.i18n = { ... }
fecha.masks.myMask = 'DD , MM, YYYY' 

New

import {parse, format, setGlobalDateI18n, setGlobalDateMasks} from 'fecha';

setGlobalDateI18n({
    // ...
})
setGlobalDateMasks({
  myMask: 'DD , MM, YYYY'
});
