The Guards are basically the services implementing interfaces like CanActivate. It works as standalone component. Let’s have a look at how to define a guard that checks to see if the user is logged in or not.<\/p>\n
\n
\r\n @Injectable({ providedIn: 'root' })\r\nexport class MyGuardWithDependency implements CanActivate {\r\n constructor(private loginService: LoginService) {}\r\n\r\n canActivate() {\r\n return this.loginService.isLoggedIn();\r\n }\r\n}\r\n\r\nconst route = {\r\n path: 'somePath',\r\n canActivate: [MyGuardWithDependency]\r\n};\r\n<\/code><\/pre>\n<\/div>\nHere, the majority of the logic is implemented by LoginService<\/strong>, and we simply use isLoggedIn<\/strong> in the guard (). With the newly installed and operational router guards, you can condense this code to:<\/p>\n\n
\r\n const route = {\r\n path: 'admin',\r\n canActivate: [() => inject(LoginService).isLoggedIn()]\r\n};\r\n<\/code><\/pre>\n<\/div>\n<\/span>5. Advancements to Stack Traces for Debugging<\/strong><\/span><\/h3>\nAs per the survey conducted, one of the major problems developers face is the improvements in stack traces. The core Angular team dig deeper into the issues with debugging experience for this reason.<\/p>\n
Because of this, Angular 15 now provides more explicable stack failures. Instead of presenting issues from third-party dependencies, the version now displays error messages.<\/p>\n
To address this problem, the team has collaborated with Chrome DevTools. The following is the example showcasing an example stack trace from an Angular project.<\/p>\n
\n
\r\n ERROR Error: Uncaught (in promise): Error\r\nError\r\nat app.component.ts:18:11\r\nat Generator.next ()\r\nat asyncGeneratorStep (asyncToGenerator.js:3:1)\r\nat _next (asyncToGenerator.js:25:1)\r\nat _ZoneDelegate.invoke (zone.js:372:26)\r\nat Object.onInvoke (core.mjs:26378:33)\r\nat _ZoneDelegate.invoke (zone.js:371:52)\r\nat Zone.run (zone.js:134:43)\r\nat zone.js:1275:36\r\nat _ZoneDelegate.invokeTask (zone.js:406:31)\r\nat resolvePromise (zone.js:1211:31)\r\nat zone.js:1118:17\r\nat zone.js:1134:33\r\n<\/code><\/pre>\n<\/div>\nThe community was able to incorporate those third-party dependencies and create linked stack traces as a result of extensive collaboration with the Angular and Chrome DevTool teams.<\/p>\n
Here are the improved stack traces.<\/p>\n

According to the roadmap, the CLI will be improved so that standalone applications devoid of modules can be generated.<\/p>\n
Additionally, it mentions some initiatives on the server-side rendering story, a weakness of Angular, and the option to use Angular independently of zone.js.<\/p>\n

Finally! The updated version of Angular V15 is here. Angular developers can create apps without NgModules, thanks to Angular 15’s stable standalone APIs. Now, angular development has become much better than ever before.
