AngularJS 1.0 was replaced by Angular 2, which is now being used to create a simple web application that syncs data using PouchDB and Couchbase Sync Gateway. The project requires Node.js 4.0+, Angular 2 CLI, Typings, and Couchbase Sync Gateway. To configure the Sync Gateway, a configuration file was created with basic settings for the database and CORS. An Angular 2 service provider was created to maintain data, which includes methods for syncing, fetching, and updating documents. The provider is imported into the application's @NgModule block. The application can be tested by running `ng serve` and accessing the project at http://localhost:4200.
