New functions in Angular ten

Important functions of Angular ten therefore significantly consist of:

  • The addition of dependency details and ng-content selectors to metadata. This proposed compiler feature would present extra metadata practical for applications this kind of as the Angular Language Support, giving the capacity to present recommendations for directives/elements defined in libraries.
  • Effectiveness improvements, achieved by lowering the dimension of the entrypoint manifest and a caching technique in the manifest. In addition, caching of dependencies is done in the entrypoint manifest and read from there somewhat than getting computed just about every time. Formerly, even if an entrypoint did not have to have processing, ngcc (Angular Ivy compatibility compiler) would parse the files of the entrypoint to compute dependencies, which would take a ton of time for huge_node modules.
  • Propagation of the appropriate worth span in an ExpressionBinding of a microsyntax expression to ParsedProperty, which in transform would propagate the span to the template ASTs (the two VE and Ivy). This proposal also is for the compiler.
  • In a resolve to the main, logic would be extra to undecorated-course migration to adorn derived lessons of undecorated lessons that use Angular functions.
  • In a breaking change, Urlmatcher’s type will reflect that it could always return null.
  • For the services-worker, a resolve has been place in for a problem in which there was a chance that the services worker will under no circumstances register when there is a extended-jogging task or recurring timeout.
  • A number of bug fixes have been produced together with the compiler averting undefined expressions in a holey array and the main averting a migration error when a non-existent symbol is imported. There is also a workaround in the main for the Terser inlining bug.
