Blockly

Google's Blockly is a web-based, visual programming editor. Users can drag blocks together to build programs. All code is free and open source.

The source for this module is in the Blockly repo.

Example Usage

import * as Blockly from 'blockly/core';
Blockly.inject('blocklyDiv', {
    ...
})

Samples

Installation

You can install this package either via npm or unpkg.

unpkg

<script src="https://unpkg.com/blockly/blockly.min.js"></script>

When importing from unpkg, you can access imports from the global namespace.

// Access Blockly.
Blockly.thing;
// Access the default blocks.
Blockly.Blocks['block_type'];
// Access the javascript generator.
javascript.javascriptGenerator;

npm

npm install blockly

Imports

Note: Using import of our package targets requires you to use a bundler (like webpack), since Blockly is packaged as a UMD, rather than an ESM.

// Import Blockly core.
import * as Blockly from 'blockly/core';
// Import the default blocks.
import * as libraryBlocks from 'blockly/blocks';
// Import a generator.
import {javascriptGenerator} from 'blockly/javascript';
// Import a message file.
import * as En from 'blockly/msg/en';

Requires

// Require Blockly core.
const Blockly = require('blockly/core');
// Require the default blocks.
const libraryBlocks = require('blockly/blocks');
// Require a generator.
const {javascriptGenerator} = require('blockly/javascript');
// Require a message file.
const En = require('blockly/msg/en');

Applying messages

Once you have the message files, you also need to apply them.

Blockly.setLocal(En);
