The guide shows how to add type safety to internationalization in projects without built-in solutions like next-intl . It covers generating TypeScript types from YAML or JSON translation files, integrating a build script to keep types up to date, and setting up file watchers or bundler plugins for automation. It also includes defining a typed t function to catch translation key errors at compile time.

In Ember.js, instead of using React's refs, the “did-insert” modifier provides access to native HTML elements. To achieve similar functionality as React 's “useImperativeHandle”, you can pass a “ref” argument to a child component and call it in the constructor, allowing the parent component to access public methods of the child. This approach ensures controlled exposure of methods and properties, maintaining encapsulation.
