Plushcap The application is developed using Symfony as the backend framework, Svelte for the frontend, and Webpack Encore to manage the bundling of the Svelte components. The Twilio Message History API is used to interact with the message history of a Twilio account. The application provides an interface to view all messages, view a single message, and delete a message. The Svelte frontend uses routing to navigate between different pages, including the main page and the detail page for each message. The Symfony backend handles the business logic and interacts with the Twilio API to retrieve and manipulate messages. The application also includes features such as pagination, filtering, and sorting of messages.
