Ember Attrs Validations

Gone are the days where you forgot to pass an attribute from a parent to a child component. This addon will throw an error only in your test runs whenever a required attribute is undefined.

Compatibility

Supports Ember CLI v2.4 LTS.

I'm planning to support only the latest LTS versions of Ember. I won't be doing tests for any versions other than that.

Usage

Currently only supports validations for required fields and data type.

import Ember from 'ember';
import AttrsValidationsMixin from 'ember-attrs-validations/mixins/validations';
 
const {
  Component 
} = Ember;
 
export default Component.extend(AttrsValidationsMixin, {
  attrValidations: {
    firstName: {
      isRequired: true,
      type: 'string'
    },
    lastName: {
      isRequired: true,
      type: 'string'
    },
    age: {
      isRequired: true,
      type: 'number'
    }
  }
});

To see what types are available, see Ember.typeOf.

Caveat

When your data is async, the isRequired will fail since the data originally will be undefined until it resolves and passes the correct value.

Current workarounds:

• Make sure async data resolves first before rendering component (e.g. use handlebar if helper).
• Make isRequired to false since in essence, you're allowing the attr to be undefined if you use async.

I don't have any plans as of the moment to seemlessly support async data. I'm open to PRs if anyone has a good idea on how to handle it.
