Isomorphic Validator

JSR-303 compatibile validator that allows to create JavaScript based validation rules with the same logic for backend and frontend.

Usage examples

Creating simple validator

Create js validation file and put in resource directory. File should contain methods returning true or false and one parameter for value of field to be tested. Create js files with validation logic

testValidator.js

function validateLengthMin(test) {
     if(test == null) {
        return true;
     }
     return test.length>5;
}

function validateLengthMax(test) {
     if(test == null) {
        return true;
     }
     return test.length<10;
}

Annotate your entity properties with @IsomorphicConstraint:

@IsomorphicConstraint(jsFilePath = "testValidator.js", jsMethods = {"validateLengthMin", "validateLengthMax"})
private String fieldToTest;

It's also possible to use multiple @IsomorphicConstraint annotations on single field. For examples please check project unit tests.
