Angular 2 Validator pattern

Question

I tried to implement a pattern validator with a built in validator in angular. I wanted to use this patter: /\S+/g but it didn't work because angular overwrites my pattern in its function You can see it here Why do they put the ^ and a $ at the beginning and the end of the string? Should I use a custom validator instead the built in? Is it a bug or working as expected?

Here is a plunkrhttp://plnkr.co/edit/OHrUitqUnhIYxsraby7J

The anchors are only added to a string pattern. If you pass a regex object (as a string), no anchors will be added. Also, you cannot use /g in the ng-pattern regex. Could you share a fiddle with your validator? — Wiktor Stribiżew

Ok, so, it means that the validator does not allow a regex object like string. Since you want to require at least one non-whitespace char, why not use ".*\\S.*"? — Wiktor Stribiżew

It seems that this validator does not allow a regex literal to be passed. You need to make sure you match the whole string. So, if you plan to require the string to have at least one non-whitespace character, use

".*\\S.*"

See the updated plunkr.
