About Advanced WebSocket Client

Advanced WebSocket Client is a Google Chrome extension designed to help construct custom WebSocket requests and handle responses for directly testing your WebSocket services. It supports the JSON request/response format, and its main feature is that you don't have to strictly follow RFC formatting rules. You can use single quotes, double quotes, or no quotes for string keys and values, as well as trailing commas in object literals. Additionally, it supports both single-line and block comments, just like in JavaScript. Shortcats: F1 - fullscreen on/off F2 - line wrapping on/off Ctrl+Q - fold/unfold a code block Alt+Ctrl+J or Cmd+Ctrl+J - format JSON Cmd+/ or Ctrl+/ - comment/uncomment line/block
