I'm working on migrating from momentjs to dayjs
How to format a custom date format into a standard one using dayjs. For e.g., I'm trying to format a date in YYYY-MM-DD+h:mm format to YYYY-MM-DD. dayjs gives me an NaN
Works perfectly fine with moment this way -
moment(effectiveDate, 'YYYY-MM-DD+h:mm').format('YYYY-MM-DD')
There are lots of such occurrences in my codebase, so I'm trying not to rely on string manipulation to achieve this.
I've been using this repl to try things out
Use dayjs version 1.8.20 and extend CustomParseFormat package.
In html file:
...
<script src="https://unpkg.com/dayjs@1.8.20/dayjs.min.js"></script>
<script src="https://unpkg.com/dayjs@1.8.20/plugin/customParseFormat.js"></script>
...
The first let's extent dayjs object:
dayjs.extend(window.dayjs_plugin_customParseFormat);
Now, you can play with your format:
const dateString = dayjs("2019-06-06+4:56", "YYYY-MM-DD+h:mm").format('YYYY-MM-DD');
console.log("Date: ", dateString);
Output: Date: 2019-06-06
You can do this way, hope this will help you
let customFormat = dayjs('2019-06-06+4:56'.replace('+','T')+':00').format('YYYY-MM-DD')
console.log('Custom format conversion1 - ', customFormat )
