To install all dependencies, run yarn. You may use npm, but note that only a yarn lockfile will be provided and accepted in PRs. If you have disabled postinstall scripts, run yarn generate-protocol to run the code generator on the flatbuffer files.

Run yarn build to execute the full build pipeline. You can also build individual parts with the other build scripts in package.json:

Building THNK with yarn build:thnk and the adapters with yarn build:adapters outputs a bundle to the dist folder. yarn build:extensions automatically inserts those into the THNK extensions in extensions.

To test your changes, import the extension with your changes into GDevelop. If you make changes to the extension itself, don't forget to export it back to the extensions folder.

Before submitting a PR, make sure that your code builds & fully functions within the extension, and that it passes both typescript & jest tests. Run yarn ts && yarn test to run both checks. Make sure the extensions in extensions are properly generated with the latest version of your code. In case of doubts, run yarn build again before committing.

There are a few main folders that you need to keep in mind while contributing:

• extensions - Contains the GDevelop extensions files. While most of the important code is in code, the extensions themselves need to be modified to add actions, conditions, etc. You also need them to actually use the built THNK code.
• protocol - Contains FlatBuffers protocol definitions. Anything that transits between the server and client must be defined through a FlatBuffer ServerMessage or ClientMessage, depending on which side will be sending that message.
  • After changing a file there, you need to run yarn generate-protocol to run codegen for the FlatBuffers files before using the modified interfaces in code
• types - GDJS type definitions. They were generated automatically with TSC.
• docs - The docusaurus website and documentation.
• scripts - A few scripts used for building.
• code - Contains all the THNK extension's typescript code. All imports are relative to this directory: import "server"; would import code/server.
  • server - All the server-relevant code.
  • client - All the client-relevant code.
  • adapters - Contains the different adapters' implementations.
  • types - Useful type definitions: global.d.ts defines the THNK global namespace and thnk.d.ts overrides GDevelop type definitions with the additional properties THNK adds.
  • utils - Misc. Code that is relevant for both server and client.
