![]() Developers could conditionally disable animations from this version onwards. Four new events: GuardsCheckStart, GuardsCheckEnd, ResolveStart, ResolveEnd joined the existing set of life cycle event such as NavigationStart. New router life cycle events for Guards and Resolvers were added. This version introduced HttpClient, a smaller, easier to use, and more powerful library for making HTTP Requests. AngularJS was based on MVC architecture while Angular 2 was built using MVVM architecture. Below is the list of all major changes done in each version:Īngular 2 was a complete rewrite of AngularJS. With every major update, Angular team tries to resolve some critical issues which would eventually help meet the end goal of developing a " simple, fast and small framework". Similar to this, there are multiple changes done to for the tooling support. With the Angular 12, Angular components will now support inline Sass in the styles field of the decorator. Compatibility with Angular material, reduction of bundle size are some of the steps in this direction. With the continuous effort to make the framework better, the team pays special attention to increase the performance. ng add adds the NPM package for a published library to the workspace, and configures the project in the current working directory (or the default project if you are not in a project directory) to use that library, as specified by the library's schematic. Ng update and ng add features were added in the Angular 6 version. Although this is not mandatory but it is recommended to do so for the following reasons:įrom the introduction of Angular CLI in Version 4 to usage of WebPack 5 in the Angular 12, the upgraded versions help us developer to write a better and efficient code. A patch release and pre-release ( next or rc) build almost every weekĪs newer versions are released, it is a good practise to stay updated with the latest version.1-3 minor releases for each major release.12 months of long-term support (LTS), during which only critical fixes and security patches are released.Īs per the official website, Angular Team releases:.6 months of active support, during which regularly-scheduled updates and patches are released.Typically, all major releases are supported for 18 months which includes: Besides this, all the Angular versions are backward compatible. The Angular Team has an excellent support system for the the older versions. No developer assistance is expected during update. Patch releases are low risk, bug fix releases. We update peer dependencies in minor versions by expanding the supported versions, but we do not require projects to update these dependencies. These are fully backward-compatible no developer assistance is expected during update, but you can optionally modify your applications and libraries to begin using new APIs, features, and capabilities that were added in the release. Minor releases contain new smaller features. When updating to a new major release, you might need to run update scripts, refactor code, run additional tests, and learn new APIs. According the official website, the significance of each of these is as mentioned below: Major releases contain significant new features, some but minimal developer assistance is expected during the update. For example, version 7.2.11 indicates major version 7, minor version 2, and patch level 11. This frequent update has made Angular one of the best choices for client side development.Īs per the semantic versioning syntax, Angular version numbers have three parts:. The new version adopted semantic versioning with an aim to release new updates constantly. Angular Upgrade and Versioning:ĪngularJS, the first version of the concept was completely rewritten, and was released as Angular 2 in the year 2016. "Įver since its development, Angular is widely used for client side development, Single Page Applications(SPAs) and Progressive Web Apps(PWAs). TypeScript is designed for the development of large applications and transcompiles to JavaScript. It is a strict syntactical superset of JavaScript and adds optional static typing to the language. Wikipedia defines Typescript as: - "A programming language developed and maintained by Microsoft. ![]() ![]() It is developed using TypeScript, the superset of JavaScript. What is Angular?Īngular is an open source framework developed and maintained by the Angular Team at Google. While Angular upgrade is a choice, it should be diligently done in order to utilise the maximum benefits of the framework. ![]() We have successfully been able to do so because we take this as a priority. We started with Angular version 2 and recently updated it to 12. At Halodoc, we use Angular framework for client side development of all our websites. ![]()
