I am using parsley js for validating input and I am using the data-parsley-pattern which allows me to pass in regular expression.

I am trying to validate the string to m

    \S{3,}
    

    \S{3,} match any non-white space character [^\r\n\t\f ]

    Quantifier: {3,} Between 3 and unlimited times, as many times as possible, giving back as needed [greedy]

    e.g. abc or abc def

    That, as pointed out by Wiktor Stribiżew, only matches consecutive characters. If you mean "the input can have any number of whitespaces, anywhere, as long as there are at least three non-whitespace characters anywhere" then maybe:

    .*\S.*\S.*\S.*
    

    Anything or nothing, non-witespace, anything or nothing, non-whitespace, etc.

    e.g. a b c or ab c or abc
