This is a plugin that will allow using validate.js in your Aurelia application for expressive validation. Karma/Jasmine testing is also configured.

To keep up to date on Aurelia, please visit and subscribe to the official blog and our email list. We also invite you to follow us on twitter. If you have questions, please join our community on Gitter. If you would like to have deeper insight into our development process, please install the ZenHub Chrome or Firefox Extension and visit any of our repository's boards. You can get an overview of all Aurelia work by visiting the framework board.

Validation is performed using validate.js. You can visit their official site to get more information about how to use all of the validation rules.

You can use a decorator or the fluent syntax, both are shown. Here are the base rules -

Ensure it is a date

export class Model {
  @date myDate = new Date();
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('myDate')
        .date();
  }
}

Ensure it is a datetime

export class Model {
  @datetime myDate = new Date();
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('myDate')
        .datetime();
  }
}

Ensure it is a valid e-mail format

export class Model {
  @email email = 'patrick@example.com';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('email')
        .email();
  }
}

Ensure it matches another property on the same object

export class Model {
  @equality('password') confirmPassword = 'password1';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('confirmPassword')
        .equality('password');
  }
}

Disallow a set of values

export class Model {
  @exclusion(['blue']) color = 'red';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('color')
        .exclusion(['blue']);
  }
}

Ensure it matches a regex

export class Model {
  @format(/\d{5}(-\d{4})?/) zipCode = '90210';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('zipCode')
        .format(/\d{5}(-\d{4})?/);
  }
}

Ensure it is included a set of values

export class Model {
  @inclusion(['blue', 'red']) blueOrRed = 'yellow';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('blueOrRed')
        .format(['blue', 'red']);
  }
}

Ensure it is a certain length

export class Model {
  @length({ minimum: 5, maximum: 25 }) password = 'equal';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('password')
        .length({ minimum: 5, maximum: 25 });
  }
}

Ensure it is a number (additional validation available, check validate.js documentation for more options)

export class Model {
  @numericality({ onlyInteger: true, lessThan: 115, greaterThan: 0 }) age = 25;
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('age')
        .length({ onlyInteger: true, lessThan: 115, greaterThan: 0 });
  }
}

Ensure it is set

export class Model {
  @presence lastName = 'Skywalker';
  @required lastName = 'Skywalker';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('firstName')
        .required();
  }
}

Ensure it is a valid URL

export class Model {
  @url website = 'http://www.google.com';
}

export class Model {
  constructor() {
    this.validator = new Validator(this)
      .ensure('website')
        .url();
  }
}

To build the code, follow these steps.

1. Ensure that NodeJS is installed. This provides the platform on which the build tooling runs.
2. From the project folder, execute the following command:

npm install

3. Ensure that Gulp is installed. If you need to install it, use the following command:

npm install -g gulp

4. To build the code, you can now run:

gulp build

5. You will find the compiled code in the dist folder, available in three module formats: AMD, CommonJS and ES6.

6. See gulpfile.js for other tasks related to generating the docs and linting.

To run the unit tests, first ensure that you have followed the steps above in order to install all dependencies and successfully build the library. Once you have done that, proceed with these additional steps:

1. Ensure that the Karma CLI is installed. If you need to install it, use the following command:

npm install -g karma-cli

2. Ensure that jspm is installed. If you need to install it, use the following commnand:

npm install -g jspm

3. Install the client-side dependencies with jspm:

jspm install

4. You can now run the tests with this command:

karma start

There is a sample application provided that runs using the plugin itself. To run this application -

1. Change to the sample directory

cd sample

2. Install all of the sample application's dev dependencies:

npm install

3. Install all of the sample application's client-side dependencies with jspm:

jspm install

4. Do an initial build of the sample app files:

gulp build-sample

5. You can now run sample application:

gulp watch

It will watch for changes to both src and sample/src and reload the browser on change.
