ECMAScript 6 standardizes the syntax of modules. A module is simply a Javascript file that you can load either on the application startup or lazily on the as-needed basis. ES6 modules give you complete control on what code to export to the external scripts and what to keep private to the module. Prepend a variable, a function, or a class definition with the keyword export, and all other scripts in your project can import the module’s API using the import keyword. For details of using modules, read this great post by Dr. Alex Rauschmayer. But the ECMAScript 6 specification doesn’t define module loaders, which can be used both in the browsers and in the standalone JavaScript engines. Eventually all Web browsers will support the System object that knows how to import modules, but meanwhile you can use the polyfill ES6 Module Loader or, if you want to go fancy and ensu... (more)

Be careful with authorization servers

These days people are accustomed to logging in to various Web sites using third-party authorization services. Do you want to login using your Facebook or Twitter account? In technical terms, this means that you are being offered to delegate the process of authorization to a third-party service offered by Facebook, Twitter or other big guys. You’re sick and tired of creating and remembering dozens of IDs/passwords for all theses online services. Please, please login me quickly using whatever service you want. Most of such services are implemented with OAuth protocol, which allows... (more)

Every day I get an invite to connect with someone. Typically I ignore these invites unless I know the person. But I’ve never received invites to connect from a chair of board of directors of a bank. Till yesterday.  So I’ve accepted the invite. Then I’ve received an LinkedIn email from this woman stating that she had a business proposition for me, and if I was interested, she was ready to explain. She also provided her emai... (more)

Started working on the Core Angular 2 book

Over the past three years my colleagues and I prepared and delivered multiple trainings “Modern Web Development with AngularJS and Java“.  We felt pretty comfortable with the framework, and the training  was structured around building a sample Online Auction app with AngularJS on the front and Java EE on the back. During the last year we’ve developed and deployed in prod the Easy.Insure app using Google Dart and AngularDart.  So Angular became our framework of choice. When Google announced a complete re-write of the AngularJS, we were not disappointed. Angular 2 will make this ... (more)

ECMAScript 6, block-level functions, and the strict mode

I was preparing code samples for my ECMAScript 6 (ES6) workshop. ES6 has tons of new language features and programming in the next version of JavaScript is a lot of fun. In particular, ES6 supports block-level functions, so the following code should produce the error “doSomething is not defined”. { function doSomething(){ console.log("In doSomething"); } } doSomething(); And it does if you test it in ES6 Fiddle: But the best part about ES6 is that you can use it today in your real world projects. Just run it through one of the transpilers, which will convert ES6 to ES5 code ready ... (more)
