class=\"wp-block-heading\" id=\"h-introduction\"><span class=\"ez-toc-section\" id=\"Introduction\"><\/span>Introduction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The core Angular development team, the 13th anniversary of Angular\u2019s red shield, has set the latest version of <strong>Angular 17 <\/strong>release date on <strong><em>8 November, 2023<\/em><\/strong>. Following its traditional way of a major release every six months and 1-3 minor releases for each major release, Angular is the time idol for the community worldwide. To date, it is not just Angular 17 but v17.1 and v17.2, which have also been released for the developers to look at and get even more excited with the latest features and changes. However, these new updates will surely take the community by storm as, this time, the Google Team has outdone themselves with the latest Angular release.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-s-new-in-angular-17-features-and-updates\"><span class=\"ez-toc-section\" id=\"Whats_New_in_Angular_17_Features_and_Updates\"><\/span>What\u2019s New in Angular 17 Features and Updates<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/positiwise.com\/technologies\/angularjs-development\">AngularJS<\/a><\/strong> was the first step toward the emerging wave of JavaScript frameworks for the increasing need for rich web experiences. The development team already did great with the Angular 16 version, but with Angular 17, they have been setting up new standards for performance and developer experience.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-new-look-and-feel\"><span class=\"ez-toc-section\" id=\"The_New_Look_and_Feel\"><\/span>The New Look and Feel<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Angular v17 has introduced itself to an entirely new branding and logo with a great new feel, which previously used to be a red shield. Also, the new website was launched in the beta version. The reason behind the beta version is that it is still under construction in terms of APIs with many improvements, such as&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ability to experiment with new features in the sandbox,<\/li>\n\n\n\n<li>New tutorials with the option of creating them within the sandbox<\/li>\n\n\n\n<li>The brand-new organization by theme (component, form, accessibility, best practices, and more)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-future-formed-angular\"><span class=\"ez-toc-section\" id=\"The_Future_Formed_Angular\"><\/span>The Future Formed Angular<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Angular Renaissance event to showcase Angular&#8217;s new branding continues at full throttle with a few previous versions. The team has been picking up the pace with improvements such as signal-based reactivity, hydration, standalone components, directive composition, and many other features. Despite the rapid evolution of Angular, the branding still fails to catch up with the pace and is almost equal to the early days of Angular.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-angular-dev\"><span class=\"ez-toc-section\" id=\"Angulardev\"><\/span>Angular.dev<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Angular.dev is now released in the beta preview and is set to be the default website in the Angular v18 version. It is the new future home for the Angular developers. The new site entails revamped documentation with a new structure, new guides, improved content, and an inbuilt platform for an interactive learning journey to help you learn Angular and the Angular CLI at your specific pace within the browser.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The new interactive learning experience, being the product of WebContainers, enables the developers to feel the power of Angular CLI in any modern-day web browser.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-in-built-control-flow\"><span class=\"ez-toc-section\" id=\"In-Built_Control_Flow\"><\/span>In-Built Control Flow<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The v17 comes with an in-built Control Flow, a new block template syntax that gives you powerful features with simple, declarative APIs, a new declarative syntax of writing control flow directly into the template, thereby eliminating the need for&nbsp;<strong><em>*ngIf<\/em><\/strong>,&nbsp;<strong><em>*ngFor<\/em><\/strong><em>,<\/em>&nbsp;and&nbsp;<strong><em>ngSwitch<\/em><\/strong>&nbsp;which used to be a directive-based control flow. The Angular compiler transforms the syntax into efficient JavaScript instructions that can perform control flow, lazy loading, and more.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The in-build control flow allows for more ergonomic syntax that is identical to JavaScript, thus more intuitive and requiring less referring to the documentation, better type checking, and better type narrowing. It exists in the build-time, which reduces the runtime footprint and could drop the bundle size by up to 30 kb and further improve your core web vital scores. Also, it is available by default without the need for add-on imports.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-conditional-statements\"><span class=\"ez-toc-section\" id=\"Conditional_Statements\"><\/span>Conditional Statements<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now, looking at the side-by-side comparison. with <strong><em>*ngIf <\/em><\/strong>&#8211;<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;htmlmixed&quot;,&quot;mime&quot;:&quot;text\/html&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;HTML&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;html&quot;}\">&lt;div *ngIf=&quot;loggedIn; else anonymousUser&quot;&gt;\n  The user is logged in\n&lt;\/div&gt;\n&lt;ng-template #anonymousUser&gt;\n  The user is not logged in\n&lt;\/ng-template&gt;<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">With an inbuilt statement, the condition will look as &#8211;<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;text\/javascript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;JavaScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;js&quot;}\">@if (loggedIn) {\n  The user is logged in\n} @else {\n  The user is not logged in\n}<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The feature to provide content for <strong>@else <\/strong>directly is a significant simplification compared to the else clause of the legacy <strong>*ngIf <\/strong>alternative. The current flow also makes it insignificant to have <strong>@else<\/strong> if, which previously has been almost impossible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We can realize the improved ergonomics with <strong>*ngSwitch<\/strong> &#8211;<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;text\/javascript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;JavaScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;js&quot;}\">&lt;div [ngSwitch]=&quot;accessLevel&quot;&gt;\n  &lt;admin-dashboard *ngSwitchCase=&quot;admin&quot;\/&gt;\n  &lt;moderator-dashboard *ngSwitchCase=&quot;moderator&quot;\/&gt;\n  &lt;user-dashboard *ngSwitchDefault\/&gt;\n&lt;\/div&gt;<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Now, with the inbuilt control flow, it turns out as follows:<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;htmlmixed&quot;,&quot;mime&quot;:&quot;text\/html&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;HTML&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;html&quot;}\">@switch (accessLevel) {\n  @case ('admin') { &lt;admin-dashboard\/&gt; }\n  @case ('moderator') { &lt;moderator-dashboard\/&gt; }\n  @default { &lt;user-dashboard\/&gt; }\n}<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The new control flow also offers better type narrowing in the individual branches within the <strong>@switch<\/strong>, which is a complex thing in <strong>*ngSwitch.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-in-built-for-loop\"><span class=\"ez-toc-section\" id=\"In-Built_For_Loop\"><\/span>In-Built For Loop<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Another of the new features of v17 Angular is the inbuilt loop introduced on top of the developer experience improvements, giving a tremendous boost to the latest Angular version speed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The basic syntax is:&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;application\/typescript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;TypeScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;typescript&quot;}\">@for (user of users; track user.id) {\n  {{ user.name }}\n} @empty {\n  Empty list of users\n}<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">There is often a performance hiccup in apps due to the absence of trackBy function in <strong>*ngFor<\/strong>. A few differences in <strong>@for<\/strong> are that they track mandatory to deliver fast diffing performance. Also, it is easier to use it since it is just an expression rather than a method in the component\u2019s class. The inbuilt <strong>@for<\/strong> loop presents a shortcut for collections with zero items via an optional <strong>@empty<\/strong> block.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>@for<\/strong> statement here uses an entirely new diffing algorithm and offers better implementation than <strong>*ngFor<\/strong>, making it upto 90% faster runtime for <a href=\"https:\/\/krausest.github.io\/js-framework-benchmark\/current.html\" rel=\"nofollow\">community framework benchmarks<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Built-in control flow is currently available in Angular v17 under the preview.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another design goal of the in-built control flow is to allow for entirely automated migration. You can use the command below to leverage it in your current projects.<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;text\/javascript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:false,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;firstLineNumber&quot;:&quot;1&quot;,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;JavaScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;js&quot;}\">ng generate @angular\/core:control-flow<\/pre><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-deferrable-views\"><span class=\"ez-toc-section\" id=\"Deferrable_Views\"><\/span>Deferrable Views<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Deferrable views are the latest addition to Angular 17. It enhances the performance along with the developer&#8217;s experience. This feature enables your development team to defer the rendering of certain parts of your application until and unless they are needed, thereby improving the overall performance of your application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;With the new version, the deferrable views only enable declarative and assertive deferred loading with unprecedented ergonomics. Before this, you needed to use the ViewContainerRef for lazy load while managing the complexity for cleanups, loading errors, showing a placeholder, and others. Taking care of various corner cases may result in some non-trivial codes, which are hard to test and debug.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-improved-server-side-rendering-ssr\"><span class=\"ez-toc-section\" id=\"Improved_Server-Side_Rendering_SSR\"><\/span>Improved Server-Side Rendering (SSR)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Server Side Rendering in Angular v17 has markedly improved. The latest version brings forth a stable SSR integration, thereby delivering several benefits, including reduced build duration, better rendering, improvement in SEO applicability, and further improvements via rendering of HTML to users. As a developer, you can start a project with the SSR flag below:<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;text\/javascript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;JavaScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;js&quot;}\">ng new \nmy-app -ssr<\/pre><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Also, even if you don\u2019t specify the ssr flag, the creation of assistant will ask if you want to start the new project using the ssr. If you wish to add the SSR to an existing project. In that case, you can use the command given below:&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-codemirror-blocks-code-block code-block\"><pre class=\"CodeMirror\" data-setting=\"{&quot;showPanel&quot;:true,&quot;languageLabel&quot;:false,&quot;fullScreenButton&quot;:false,&quot;copyButton&quot;:true,&quot;mode&quot;:&quot;javascript&quot;,&quot;mime&quot;:&quot;text\/javascript&quot;,&quot;theme&quot;:&quot;lucario&quot;,&quot;lineNumbers&quot;:true,&quot;styleActiveLine&quot;:false,&quot;lineWrapping&quot;:true,&quot;readOnly&quot;:true,&quot;disableCopy&quot;:true,&quot;fileName&quot;:&quot;&quot;,&quot;language&quot;:&quot;JavaScript&quot;,&quot;maxHeight&quot;:&quot;400px&quot;,&quot;modeName&quot;:&quot;js&quot;}\">ng add \n@angular\/ssr<\/pre><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-typescript-5-2\"><span class=\"ez-toc-section\" id=\"TypeScript_52\"><\/span>TypeScript 5.2<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The latest Angular version has TyperScript 5.2 in-built and many new enhancements within the TypeScript language, including code readability, secure type, and improved overall development experience. The new contributions of TypeScript 5.2 to Angular 17 are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>MetaData with Decorator Programming<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Decorator programming can add metadata, classes, or function behaviors for better, more organized, reusable code. It also enables you to extend the functionality and customization. You can also implement it with other tools, such as TypeScript compiler plugins or Angular components, to improve efficiency.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-module-augmentation\"><span class=\"ez-toc-section\" id=\"Module_Augmentation\"><\/span>Module Augmentation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now, you can expand the existing modules with the new members and customize the code without modifying the original code. These module augmentations are designed to extend the JavaScript objects like arrays and custom methods. It also helps write and organize the code per your development needs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">TypeScript 5.2 in Angular 17 supports the union of arrays, type inference, and type aliases; this brand-new feature also allows for enhanced type-checking for template array literals and empowers decorator programming.<\/p>\n\n\n\n<div class=\"wp-block-group bg-shaps has-background has-global-padding is-layout-constrained wp-container-core-group-is-layout-71df2e02 wp-block-group-is-layout-constrained\" style=\"border-radius:5px;background-color:#151e2c;padding-top:var(--wp--preset--spacing--40);padding-right:var(--wp--preset--spacing--40);padding-bottom:var(--wp--preset--spacing--40);padding-left:var(--wp--preset--spacing--40)\">\n<h2 class=\"wp-block-heading has-text-align-center mt-0 has-base-color has-text-color\" id=\"h-get-expert-angularjs-development-services-for-your-project\"><span class=\"ez-toc-section\" id=\"Get_Expert_AngularJS_Development_Services_for_Your_Project\"><\/span><strong>Get Expert AngularJS Development Services for Your Project<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"has-text-align-center fs-5 lh-base has-base-color has-text-color wp-block-paragraph\">Seeking for top-notch Angular JS development company?

This differs from the traditional behavior that marks all parents as dirty. Using this in conjunction with OnPush improves performance. Also, this represents an initial step towards the envisioned more precise change detection.<\/li>\n\n\n\n<li>The Angular CLI generates standalone pipes, components, and directives. By default, <strong><em>ng new<\/em><\/strong> also offered independent component bootstrapping. The <strong><em>-standalone<\/em><\/strong> false switch can now turn off the behavior.<\/li>\n\n\n\n<li>The Ivy compiler, initially released in Angular 12, is the next version of the Angular compiler. The new version provides for increased speed and effectiveness.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-conclusion\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><a><\/a>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With this, we can infer that Angular 17 has developed numerous new features and improvements within the Angular ecosystem. This is not the end; many more features are in the pipeline to be introduced, with the core team working hard to deliver numerous surprising features and updates that will change how you develop your applications.
