Slumber a TUI HTTP Client Slumber is a terminal-based HTTP client that operates in both a Terminal User Interface (TUI) and Command Line Interface (CLI) mode, designed for interacting with REST and other HTTP services. Its configuration is defined in a shareable YAML file called a request collection, which is used by both modes. The TUI allows for interactive request sending and response viewing, while the CLI is suited for quick requests and scripting. Introduction Slumber is a terminal-based HTTP client, built for interacting with REST and other HTTP clients. It has two usage modes: Terminal User Interface TUI and Command Line Interface CLI . The TUI is the most useful, and allows for interactively sending requests and viewing responses. The CLI is useful for sending quick requests and scripting. The goal of Slumber is to be easy to use, configurable, and sharable. To that end, configuration is defined in a YAML file called the request collection. Both usage modes TUI and CLI share the same basic configuration, which is called the request collection.
