Sometime we need to add validation for no space allow on input field. so here i will give you example of How to validate Whitespace / spaces in angular applicarion?, you can easily use custom validation for Angular No Whitespace Allowed Vaidator for reactive form.

You can easily use this custom validation for no space allowed with angular 6, angular 7, angular 8 and angular 9.

Actually, few days ago i was working on my reactive form and i need to add custom validation for not allow white space. i thought i will use something if condition or anything else. but i found way to create custom validation for rules for this. so i created very simple way for no space allow to input field in angular application.
