- 20. 20 Hybrid Mobile App Frameworks
- 21. 21 Ionic 2 complete open-source SDK for hybrid mobile app development Enables the creation of cross platform mobile applications with HTML, CSS and JavaScript(Angular 2) leverage the skills you already have from developing web applications Take advantage of progressive web apps Target all major mobile platform Native functionality is easy to implement
- 22. 22 Meteor An open-source JavaScript web framework written using NodeJS An Isomorphic development ecosystem Allows rapid prototyping and produces cross-platform (Android, IOS, Web) code It is a cohesive development platform Reactivity – Real time syncing of data is built into meteor at the core It has lots of other cool things like a templating system called Blaze, A database on client called Minimongo and more
- 24. 24 Webpack Webpack is a module bundler It splits the dependency tree into chunks loaded on demand It Keeps initial loading time low Provide ability to integrate third party libraries as module Provide ability to customize nearly every part of the module bundler Best suited for big project Angular 2 command line interface (CLI) tool uses webpack
- 25. 25 Task Runners Grunt • Linting our JS files • Minifying JS files • Compiling Less • Watching for file change etc. Gulp • Spinning up a web server • Bundling and minifying libraries and stylesheets • Refreshing your browser when you save a file • Quickly running unit tests • Running code analysis • Less/Sass to CSS compilation • Copying modified files to an output directory etc.

Editor's Notes
- Lot of new releases and enhancements are seen in multiple technologies in last year comprising of multiple languages like python, java, rubby, JavaScript etc. The key driving force behind all of them was to make development easy, efficient and provide best in class performance from the underlying technology Other areas like IoT, Mobility, Big Data, Containers etc. had also become more popular the trend is going to continue in 2017 as well.
- End of traditional request/response model where each user event used to send a post back to the server and whole page reloaded in the response to that request. Browser, Mobile, Tablet, POS device and other hand held devices consuming services from same back end With web standardization and widely adaptation of HTML5 and CSS3 client are now geared up to take the complete responsibility of visualization aspect of the application. Backend are just thin layer serving the data and supporting business logic. This has optimized the bandwidth utilization to a great extent.
- HTML is technically not a programming language but a markup language to create web UI. Semantic elements = elements with a meaning, A semantic element clearly describes its meaning to both the browser and the developer This made it possible for search engines to identify the correct web page content Geolocation – Get user location. Works precisely with devices supporting GPS. Canvas – Draw graphics on the fly using javascript Offline – Application cache to make offline version of web app by creating cache manifest file
- Mixins- Create reusable chunk of CSS to avoid writing repetitive code Inline Import – Allow to create partials and use them using imports
- 5 time faster then angular 1
- Immutability – The key for react framework to identify changes. Flux – A design pattern for unidirectional data flow.
- Shifting UI Design to Experience Design We saw huge popularity in chatting and social media applications. Same is going to continue in current year. The once interesting observation is the now UI are becoming conversational. You have seen a small blog with lots of comments. That’s about conversational UI. Web apps are moving toward card based layout for their home page and providing path to explore more details from there. The days are now gone when you see the same picture of smiling person on “Our Team” page of all the website.
- Bootstrap team is working on Alpha (6). After that it may go in beta phase. There is no official release date given but it is expected to be released in March 17
- Hybrid mobile application in “Web View”
- Progressive Web apps - A new way to deliver amazing user experiences on the web. Native functionality – Using Cordova Plugins available for different platforms
- Isomorphic – Single language for both front end and backend Cohesive - a collection of libraries and packages that are bound together in a tidy way to make web development easier. DDP (Distributed Data Protocol) - A protocol for sending data over websockets. Dubbed 'REST for websockets'. EJSON - An extension of JSON to support serializing more data types like Dates and Binary. Blaze - A reactive library built to marry Tracker & Spacebars up to create live updating user interfaces. Similar to Angular, Backbone, react Minimongo - A client side mongo library that synchronizes data over DDP and allows the client to reactively consume mongo data
- how easy it will be for you to start your day if your alarm clock is not only able to wake you up but also able to communicate with your brewer to inform it that you are awake at the same time notifies your geezer to start water heating. Or you wearable wrist health band keeps track of your vitals to inform you when you are most productive during the day
- Analysis of crime records and help predict where crimes are likely to occur and help cops to take preventive actions
