node-date-parser
Advanced tools
Readme
This is a simple date parsing module written in typescript; similar to the date()
function of PHP. The module returns a string according to the given formatter string using the given date.
Install with NPM
npm install node-date-parser
In a Typescript project
import
the module then create the parser object.
import DateParser from 'node-date-parser';
parser = new DateParser();
In a Javascript project
require
the module
const DateParser = require('node-date-parser').default;
const parser = new DateParser();
// Or do it in one step
const parser = new (require('node-date-parser').default)();
public constructor(locale: string = "en")
The constructor expects 1 conditional argument: the locale. Check the the locale section for the available languages. If this argument is not provided the locale defaults to "en"
.
If an unknown locale is provided, the constructor will throw an error.
The parser is shipped with a few locale files which contains translated data. Currently these locales can be used:
If you would like to use the parser with a different locale you can pass a json file using the loadCustomLocale method.
Feel free to share your translated locale file with me so it can be published with the parser.

console.log(dateParser.parse("Y-m-d H:i:s", new Date(2021, 11, 1, 14, 42, 39)));
public loadCustomLocale(customLocaleJson: DateParserLocale): void
If you want to use different languages with the parser which are not shipped with it, you can pass a JSON file using this method. The json must match the DateParserLocale
interface.
The method itself doesn't validate the json against the interface!
