Hello block builders!

The 2022 Q3 release of Blockly, v9.0.0, is out.  In this release:
  • Blockly core is now in TypeScript! If you use TypeScript, you should notice better type declarations for Blockly.
  • Blockly is transpiled to ES2015, no longer ES5. ES2015 is supported by all major browsers.
  • Blockly is no longer guaranteed to be compatible with Internet Explorer, and some IE workarounds have been removed.
  • If you're using modules, the way you import generators has changed. See the generators documentation for more information.
Full release notes are below. As always, we welcome bug reports and pull requests.

Cheers,

Christopher Allen


Q3 2022 Release (v9.0.0)

@maribethb maribethb released this 9 minutes ago

Highlights

  • Blockly core is now in TypeScript! If you use TypeScript, you should notice better type declarations for Blockly. There may still be some rough edges; please tell us about them or submit a fix.
  • Blockly is transpiled to ES2015, no longer ES5. ES2015 is supported by all major browsers.
  • Blockly is no longer guaranteed to be compatible with Internet Explorer, and some IE workarounds have been removed.
  • If you're using modules, the way you import generators has changed. See the generators documentation for more information.

Migration

To help deal with breaking changes from this release:

  1. Run npx @blockly/migrate rename --from <your version> <./path/to/my/files*>
  2. Run npx @blockly/migrate fix-imports --from <your version> <./path/to/my/files*>

These commands will automatically modify your files so that they are compatible with version 9. The first command will automatically rename properties that have been renamed. And the second command will add/fix imports for blocks/generators that have been moved.

Some problems may still exist after running the migration scripts, but the majority of them should be fixed!

The AppEngine test site has now been updated to v9.0.0! So if you want to give it a manual test there you can =)

Hello block and field creators!

One thing that may not be obvious to folks who have created custom blocks and fields is that the mechanism for sub-classing existing Blockly classes has changed in v9.0.0 and the existing old mechanism will no longer work with v9.  Unless I missed something, you can no longer define your classes as functions and use the Blockly.utils.object.inherits function to make your class a subclass of a Blockly class.  You'll see various errors relating to superclass constructors and calls to superclass methods.  

Basically, you will now need to use the ES6 class ... extends ... syntax to create your class and use the super keyword to call the superclass constructor and methods.  That also means putting any methods that call superclass methods into the class declaration.  

I believe that you can still define other non-static fields and methods on the class's prototype property, but for consistency and clarity you might want to pull all that stuff into the class declaration.

-Mark
