Intl global objectThere are three ways to use any-date-parser:
1.) Use a new function directly on Date:
Date.fromString(string, locale) - Parses a string and returns a Date
objectDate.fromAny(any, locale) - Return a Date object given a Date, Number
or string to parseExample:
require('any-date-format');
Date.fromString('2020-10-15');
// same as new Date(2020, 9, 15, 0, 0, 0, 0)
2.) Use the parser object:
parser.fromString(string, locale) - Parses a string and returns a Date
object. It is the same function as in option 1.parser.fromAny(any, locale) - Return a Date object given a Date,
Number or string to parse. It is the same function as in option 1.Example:
const parser = require('any-date-format');
parser.fromString('2020-10-15');
// same as new Date(2020, 9, 15, 0, 0, 0, 0)
3.) It also exports parser with function parser.attempt(string, locale) that
returns an object with one or more integer values for the following keys: year,
month, day, hour, minute, second, millisecond, offset. Example:
const parser = require('any-date-format');
parser.attempt('15 Oct 2020 at 6pm');
// returns:
{
year: 2020,
month: 10,
day: 15,
hour: 18,
}
4.) There are npm packages that integrate any-date-parser directly into popular date libraries:
Summary:
Exhaustive list of date formats
any-date-parser supports any locale that your runtime's Intl (ECMAScript
Internationalization API) supports. In browsers that usually means the operating
system language. In Node, that means the compiled language or the icu modules
included. For unit tests, this library uses the
full-icu npm package to make all locales
available. That package is heavy and is included as a dev dependency but not a
dependency.
any-date-parser has an addFormat() function to add a custom parser.
First, parsers must have matcher or template.
matcher: A RegExp to match a stringtemplate: A string with template variables such as _YEAR_ _MONTH_ etc.
that will be converted to a regular expressionSecond, parsers must have units or handler.
units: An array of unit strings to fit matches into (year, month, day, etc.)handler: A function that takes matches and returns an object with keys year,
month, day etc.const parser,
{ Format } = require('any-date-parser');
parser.addFormat(
new Format({
matcher: /^(\d+) days? into month (\d+) in year (\d{4})$/,
units: ['day', 'month', 'year'],
})
);
Keep in mind that \d does not support other numbering system such as Chinese
or Bengali. To support those you can use the template option given in
example 3 and
example 4.
const parser,
{ Format } = require('any-date-parser');
parser.addFormat(
new Format({
matcher: /^Q([1-4]) (\d{4})$/,
handler: function ([, quarter, year]) {
const monthByQuarter = { 1: 1, 2: 4, 3: 7, 4: 10 };
const month = monthByQuarter[quarter];
return { year, month };
},
})
);
const parser,
{ Format } = require('any-date-parser');
parser.addFormat(
new Format({
template: 'The (_DAY_)(?:_ORDINAL_) day of (_MONTH_), (_YEAR_)',
units: ['day', 'month', 'year'],
})
);
const parser,
{ Format } = require('any-date-parser');
parser.addFormat(
new Format({
template: '^Q([1-4]) (_YEAR_)$',
handler: function ([, quarter, year]) {
const monthByQuarter = { 1: 1, 2: 4, 3: 7, 4: 10 };
const month = monthByQuarter[quarter];
return { year, month };
},
})
);
To remove support for a certain format, use removeFormat()
const parser = require('any-date-parser');
const dayMonth = require('any-date-parser/src/formats/dayMonth/dayMonth.js');
parser.removeFormat(dayMonth);
To create a new parser with a limited list of formats, use new Parser
const { Parser } = require('any-date-parser');
const time24Hours = require('any-date-parser/src/formats/time24Hours/time24Hours.js');
const yearMonthDay = require('any-date-parser/src/formats/yearMonthDay/yearMonthDay.js');
const ago = require('any-date-parser/src/formats/ago/ago.js');
const parser = new Parser();
parser.addFormats([time24Hours, yearMonthDay, ago]);
