Inspired by low-code editors such as Blender Nodes and Unreal Engine Blueprint, the Blocks Editor makes it possible to build Motoko smart contracts using a simple drag-and-drop interface.

Getting Started

Here are a few tips for learning the Blocks user interface:

• Complete the interactive tutorials to learn the basic editor workflow.
• Browse a variety of examples and templates available in the application.
• Select a block and press 'Q' on your keyboard to view the corresponding Quick Reference information.
• Try hovering your mouse over a block name, connection socket, or input field to view a tooltip with more context.
• Open the 'Compile' panel and press 'Build & Run' to compile, deploy and test your code on the Internet Computer.
• If you're running into an issue or have any questions, feel free to ask our Discord community!

Combine visual logic with Motoko language syntax using custom Expression blocks.

Advanced Usage

• Customize the editor and view keyboard shortcuts for common block types in the Options menu.
• Hold 'Ctrl' or 'Cmd' when opening the right-click placement menu to view and search all blocks available in the editor.
• Quickly remove connections by holding the 'Ctrl' or 'Cmd' key and clicking on a connection socket.
• Add a GitHub library using a Package block, import a file using an Import block, and call a library function using an expression block such as { Expression } or { Statement }.
• Convert a standard Motoko file to a Blocks smart contract using the { Import } and { Member } block (view the DIP721 NFT template for an example).
• Add test cases to ensure your smart contract works as intended.

Embedded Mode

Customize the Blocks Editor for your React application using the react-blocks-editor npm package.
