日期在 Node.js 中失去前导 0

Question

I need a string with current date and time in the following format:

"2021-06-02 09:37:38"

 const today = `${new Date().toLocaleDateString('sv-se')} ${new Date().toLocaleTimeString('sv-se')}`; console.log(today);

This code runs fine in any browser console I've tried, but if I run this in Node.js the leading 0's are gone in the date part (not the time part):

"2021-6-2 09:37:38"

Is there a nice way to fix this without splitting and padding?

I would prefer to avoid installing any dependencies.

EDIT: Node version is v11.15.0.

You should try to add options as a 2nd parameter to toLocaleDateString . For example try this: var options = {year: "numeric", month: "2-digit", day: "2-digit"};

If this does not fit your needs exactly refer to https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString
