    Blockly

    Blockly

    The web-based visual programming editor

    The Blockly library adds an editor to your app that represents coding concepts as interlocking blocks. It outputs syntactically correct code in the programming language of your choice. Custom blocks may be created to connect to your own application. Blockly in a browser allows web pages to include a visual code editor for any of Blockly's five supported programming languages, or your own. Blockly plugins are self-contained pieces of code that add functionality to Blockly. Blockly codelabs provide step-by-step instructions on how to use and customize Blockly. From a user's perspective, Blockly is an intuitive, visual way to build code. From a developer's perspective, Blockly is a ready-made UI for creating a visual language that emits syntactically correct user-generated code. Blockly can export blocks to many programming languages.
