A young Ember Doctor.

ember-watson can be used as an Ember CLI addon, it will extend the available list of commands.

To install, run ember install ember-watson and you are good to go.

ember watson:convert-prototype-extensions

Convert computed properties and observers to not use prototype extensions. You can specify appPath (defaults to app/) in case you want to convert code somewhere different to app/.

For more info about this please refer to the following PR Encourage decorator-style Ember.computed/Ember.observer

ember watson:convert-resource-router-mapping <routerPath>

Converts this.resource('user') to this.route('user', {resetNamespace: true }) in app/router.js.

Helps with the deprecation added in ember.js/11517.

ember watson:methodify <path>

Converts methods in file to ES6 method syntax.

ember watson:find-overloaded-cps <path>

Helps you locate all the places where your source may trigger the "Using the same function as getter and setter" deprecation.

ember watson:replace-needs-with-injection <path>

Convert needs declarations the individual properties using the new Ember.inject.controller() feature. Also convert any uses of the controllers hash to use the newly defined properties.

ember watson:remove-ember-k <mode>

Replaces all usages of Ember.K with just plain functions. The <mode> argument is mandatory and can be --empty or --return-this. Invoked with --empty it will replace Ember.K with an empty function, which is more idiomatic JS. Invoked with --return-empty it will replace it by a function that returns this so allows chaining. This command runs automatically in all folders that might contain ember code, so no <path> or --dry-run options are available.

ember watson:upgrade-qunit-tests

This command will traverse your tests directory fixing your QUnit test to use the 2.0 compatible output (see ember-cli#3197).

The following are some of the changes:

• Add import { module, test } from 'qunit' if ember-qunit is not used. You need to use ember-cli-qunit-v0.3.8 which includes QUnit's shims. See ember-cli#3245
• Import skip if used in tests: import { module,test, skip } from 'qunit'
• Add assert to callback function in test.
• Use assert inside test, e.g. ok becomes assert.ok.
• Use beforeEach and afterEach instead of setup and teardown inside module.

ember watson:use-destroy-app-helper <path>

Convert (qunit or mocha flavored) acceptance tests to utilize the destroyApp helper introduced in Ember CLI 1.13.9.

ember watson:convert-tests-to-async-await <path>

Convert (qunit or mocha flavored) acceptance tests to utilize async/await

// before:
it('can visit subroutes', function(done) {
  visit('/');

  andThen(function() {
    expect(find('h2').text()).to.be.empty;
  });

  visit('/foo');

  andThen(function() {
    expect(find('h2').text()).to.be.equal('this is an acceptance test');
    done();
  });
});

// after:
it('can visit subroutes', async function() {
  await visit('/');

  expect(find('h2').text()).to.be.empty;

  await visit('/foo');

  expect(find('h2').text()).to.be.equal('this is an acceptance test');
});

ember watson:convert-ember-data-async-false-relationships

In Ember Data 2.0 relationships will be asynchronous by default. Sync relationships will still be supported but you will need to manually opt into them by setting { async: false } on your relationships. This task adds an explicit async: false options to all belongsTo and hasMany that either have no options or its options does not contain an explicit async value.

For more information, read ember-data 1.13 release notes

ember watson:convert-ember-data-model-lookups

This changes the way model lookups happen when working with Ember Data. When using hasMany or belongsTo, the first argument will become a dasherized string. Here's some examples:

// before, using a camelCase string
export default DS.Model.extend({
  postComments: DS.hasMany('postComment', {async: true})
});

// after
export default DS.Model.extend({
  postComments: DS.hasMany('post-comment', {async: true})
});

// before, using a variable or looking up on App.
export default DS.Model.extend({
  postComments: DS.hasMany(PostComment, {async: true})
});

// after
export default DS.Model.extend({
  postComments: DS.hasMany('post-comment', {async: true})
});

ember watson:remove-ember-data-is-new-serializer-api

Removes isNewSerializerAPI literals in your serializer code. You should use this after you make sure all your serializers are compatible with the new serializer API in 1.13. You can find more information on how to upgrade serializers here.

// before
export default DS.RESTSerializer.extend({
  isNewSerializerAPI: true
});

// after
export default DS.RESTSerializer.extend({});

You can run any of the commands passing as argument the path, file or regular expression of the files that you want to transform.

ember watson:upgrade-qunit-tests tests/unit*
ember watson:upgrade-qunit-tests tests/unit/model-test.js
ember watson:upgrade-qunit-tests tests

The same is possible with ember watson:convert-prototype-extensions and ember watson:convert-ember-data-model-lookups.

ember-watson can be used without Ember CLI too, just do npm install -g ember-watson.

Then you can use the commands from above, just with the altered syntax.

ember watson:upgrade-qunit-tests becomes ember-watson upgrade-qunit-tests

For additional help use ember-watson -h.
