This tutorial series guides readers through building a clone of Slack using Vue.js and Vonage Conversation API. The first part covers setting up the project, installing dependencies, creating an Express.js server, generating a Vue.js client application, and configuring the proxy for API requests. It also introduces hot reloading, concurrent execution, and styling with Tailwind CSS. Additionally, it sets up a full-screen loading component, connects to the Vonage Conversation API, and creates a basic messaging UI. The goal is to build a chat client that resembles Slack's user experience, which will be continued in part 2.
