Angular is a TypeScript based open source front-end web application development framework. It is one of the most popular frameworks for web application development.
Let’s take a look at the brief history of Angular.
In 2010, Google launched the framework called AngularJS for developing the web applications
, Angular because of the “<>” in HTML.
Google wanted a framework to solve the difficult problems when building the large and cross-platform application. That’s why they released Angular 2.0 on September 14, 2016, and team had decided to follow the semantic versioning practice of major, minor and patch.
After that, the updates and bug fixes were released in different versions such as Angular4, Angular5, and so on. The latest version is Angular 7.0 which is released in October 2018.
Let’s discuss the features of Angular 7.0 CLI get new features
Angular CLI has updated the version 7.0.2 and added some new features like it will prompt users while typing common commands like “ng-add” or “ng-new” to help you to discover built-in features like routing or SCSS support. While creating new projects you take the advantage of Bundle Budgets in CLI. Speed up the application performance
Continuing to focus on performance, Angular developers analyzed the common mistake across the ecosystem. They discovered that many developers include “reflect-metadata” polyfill in production, which is only needed in development. To fix this they removed the “polyfills.ts” file, and then include it as a build step when building the application in the JIT mode.
To speed up the performance of new applications platform give the warning if the initial bundle is more than 2MB and error at 5MB, which developer can modify in “angular.json” file. Advantages of Material Design
Material Design got a big update in 2018, Angular Material users updating to version 7 get the minor visual differences reflecting the updates to the Material Design
You can also get the advantage of Virtually Scrolling, Drag and Drop, and newly added CDK (Component Development Kit). Virtual scrolling provides efficient way to scroll large list
Virtual scrolling loads elements from the DOM based on the visible parts of a list, it makes possible to build very fast experiences for users with very large scrollable lists.
For example, loading hundreds of elements can be slow in any browser, virtual scrolling gives you the efficient way to simulate all items being rendered by making the height of the container element the same as the height of the total number of elements to be rendered, and then only rendering the items in view. User can reorder the list with Drag and Drop
Drag and drop support now in the CDK and includes automatic rendering as the user moves items for reordering lists and transferring items between lists. You can customize the drag area using the handle, for example, if you want to restrict the specific user can use handle elements then you can do it by adding the “cdkDragHandle” directive to an element inside of “cdkDrag”. Improve accessibility of application
Increase the accessibility of your application by using the native “select” element inside the “mat-form-field”. The native select has some performance, accessibility, and usability advantages but “mat-select” gives you full control over the presentation options. Angular elements
Angular elements now support the content projection using web standards for custom elements. Community Partners
The community is the major reason behind the huge success of Angular and now they have been working to partner with several community projects they have been launched recently.
• Angular Console is a downloadable console for starting and running Angular projects on your local machine.
• @angular/fire is a new home on npm and its first stable release for Angular.
• NativeScript is possible to have a single project that builds for both web and installed applications.
• StackBlitz 2.0 has been released and now includes the Angular Language Service, and features like tabbed editing. Documentation and user guide
Angular developers always working hard to improve the user guides and reference materials. The document of angular.io now includes the reference material for the Angular CLI. Dependency on third party project
Angular developers updated their dependencies on major third-party projects.
• TypeScript 3.1
• RxJS 6.3
• Node 10 – They added support for Node 10 but they support 8.
This all about the features of Angular 7. Now, let’s discuss how to update Angular 7
If you are already running Angular App on Angular 6 and RJXS6, then just update your @angular CLI and also update your angular material.
Visit update.angular.io for detailed information and guidance on updating your Angular version. Developers have reported that Angular 7.0 update is faster than ever and many apps take less than 10 minutes to update. What about Ivy?
Angular developers continuing work on the new initiative called Ivy. It is under the development phase and it is not the part of Angular 7.0 release. Angular developers are beginning to validate the backward compatibility with the existing applications and soon announce an opt-in preview of Ivy as soon as it is ready in the coming months.
Angular 7 looks like the more accessible solution in the modern technological trends added features like bitcoin mining, Virtual scrolling, drag and drop, Angular material, and many more. If you are planning to implement the solution based on the web and mobile technologies, make sure to consider Angular 7 as the efficient framework.
