  1. PLATFORM STATE OF THE UNION VERY VIRTUAL SUPER ONLINE

  2. POLARIS ALIGNING WITH MODERN PACKAGES

  3. PACKAGES HOW DO THEY WORK? package.json { "name": "my-app", /*

    ... */ "devDependencies": { "moment": "^2.29.2" /* ... */ } } import moment from 'moment';

  4. PACKAGES HOW DO THEY WORK? import moment from 'moment'; node_modules

    moment moment.js

  5. HOW IT ALL BEGAN THE “SCRIPT” IN JAVASCRIPT

  6. HOW IT ALL BEGAN THE “SCRIPT” IN JAVASCRIPT <!DOCTYPE html>

    <html> <head> <title>My App</title> </head> <body> <script src="underscore.js"></script> <script src="jquery.js"></script> <script src="backbone.js"></script> </body> </html>

  7. HOW IT ALL BEGAN THE “SCRIPT” IN JAVASCRIPT app/app.js window.App

    MySelectComponent = Ember.Component.extend({ /* ... */ }); app/router.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/nav-bar.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/select-menu.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); dist/my-app.js // app/app.js window.App = Ember.Application.create({ /* ... */ }); // app/router.js App.Router.map({ /* ... */ }); // app/components/nav-bar.js App.NavBarComponent = Ember.Component.extend({ /* ... */ }); // app/components/select-menu.js App.SelectMenuComponent = Ember.Component.extend({ /* ... */ }); // app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ /* ... */ });

  8. app/app.js window.App MySelectComponent = Ember.Component.extend({ /* ... */ }); app/router.js

    App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/nav-bar.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/select-menu.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); dist/my-app.js // app/app.js window.App = Ember.Application.create({ /* ... */ }); // app/router.js App.Router.map({ /* ... */ }); // app/components/nav-bar.js App.NavBarComponent = Ember.Component.extend({ /* ... */ }); // app/components/select-menu.js App.SelectMenuComponent = Ember.Component.extend({ /* ... */ }); // app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ /* ... */ }); “bundling” “bundle” TANGENT

  9. JAVASCRIPT MODULES THE NATIVE MODULES SYSTEM app/components/my-select.js import Ember from

    'ember'; export default Ember.Component.extend({ classNames: ['my-select'], init() { this._super(); this.set('isActive', false); }, click(event) { event.preventDefault(); this.toggleProperty('isActive'); }, /* ... */ }); app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ classNames: ['my-select'], init() { this._super(); this.set('isActive', false); }, click(event) { event.preventDefault(); this.toggleProperty('isActive'); }, /* ... */ }); !

  10. JAVASCRIPT MODULES THE NATIVE MODULES SYSTEM app/components/my-select.js import Ember from

    'ember'; export default Ember.Component.extend({ classNames: ['my-select'], init() { this._super(); this.set('isActive', false); }, click(event) { event.preventDefault(); this.toggleProperty('isActive'); }, /* ... */ }); app/components/my-select.js App.MySelectComponent = Ember.Component.extend({ classNames: ['my-select'], init() { this._super(); this.set('isActive', false); }, click(event) { event.preventDefault(); this.toggleProperty('isActive'); }, /* ... */ }); !
