Create views using React functionality

The goal of the project is to create views using React functionality (Routing, REST API Calls, Views) based on an existing API (Swagger, definition). A base theme working with React already exists that should be extended. Views should be created based on the API Endpoints including state-management, i.e., logged-in or logged out and also using roles (which site/endpoint is accessable). Roles are sent after login. Users should be able to register an account, login in, log out and the react app should only display certain views when logged in, otherwise display the login view. For each endpoint that represents entities, i.e., users, domains, contracts, generic views should exist, listing items in table form with pagination. Those overviews should include for each entry specific actions based on the endpoints, for example, cancel contract, view domain contacts, etc. Further for each entity at least the following views should exist, add and edit, how these views should look is heavily influenced by the API. Many API Endpoints have self-describing helpers that give back forms in [login to view URL] that include information about the data that should be submitted, what type of form fields are used and what the intial/default values are. Validation errors of certain endpoints using forms are returned using the LiformSymfony bundle. On creating forms for the frontend see [login to view URL] Not every endpoint returns validation errors or generic errors in the form of a form error object. If models are returned, these are described in the Swagger API documentation. What is needed (endpoints available) • Login/Logout pages (using set cookie) • User Management (edit own profile) • Contract View (view, dismiss) • Product (Domain: view, order, edit details) • Admin interface (details later)
