Date Validation in Nodejs
I'm a big fan of express-form
, def worth a look -- you can also use moment.js
. I've used it myself a for this very reason
from moment.js docs:
moment("2011-10-10", "YYYY-MM-DD").isValid(); // truemoment("2011-10-50", "YYYY-MM-DD").isValid(); // false (bad day of month)
Cheers, I hope this helps :)
ps - moment.js github url just in case.
As Node-Validator's documentation points out, "regex is probably a better choice".I whipped up a regex that looks pretty good, and I believe it'll get the job done, but I advise you to test it thoroughly, if you plan to use it.
/\d\d\d\d-(0[1-9]|1[0-2])-(0[1-9]|[1-2]\d|3[0-1])/
This regex will validate a date in the format YYYY-MM-DD, that you need.You can see a working code snippet that uses it here:http://tinker.io/c269b/
Good luck!
Edit:I noticed something that breaks it. This regex validates partial matches, so an input like "1970-01-011" checks out as valid. This happens because I forgot to add the start and end markers inside the regex. This is how it looks after I fixed it:
/^\d\d\d\d-(0[1-9]|1[0-2])-(0[1-9]|[1-2]\d|3[0-1])$/
The example on Tinker is also updated with the fix.
Since I was also looking into this and was checking express validator as well, I mocked up a regex as well that might help you out with validating dates.
((19|2\d)\d\d)-((0?[1-9])|(1[0-2]))-((0?[1-9])|([12]\d)|(3[01]))
