Angular 12, a planned upgrade to Google’s popular TypeScript-based web framework, has moved into a beta stage, with a preliminary release now available.

Some of the features in the beta include:

• Implementing the appendAll() method on HttpParams.
• For forms, min and max validators are being introduced.
• Exporting of a list of HTTP status codes.
• Addition of a feature to the Angular Language Service that enables accessing the locations for components that use a template file.
• The addition of diagnostics to suggest turning on strictTemplates, providing a way for the language server to retrieve compiler options diagnostics.
• A patch adding an API to retrieve the template type check block for a template, if any, at a file location, and selection of the TS node in the TCB corresponding to the template node at which the request for a TCB was made. This will help with debugging.
• The addition of command for getting components for a template file, for the language service.
