About GDevelop IDE dependencies (package.json)

GDevelop relies on some dependencies that can have special requirements.

Note on TypeScript

TypeScript here is only used to check the types in the scripts/ files. The IDE uses Flow for static typing. TypeScript is used in the game engine too (see GDJS and Extensions folders).

Storybook

Storybook is depending on webpack and babel.

• It's important to have the same webpack version as the one provided by react-scripts, hence why webpack is specified in the devDependencies.
• babel-loader is specified to be the exact version required by react-scripts (because react-scripts wants the exact version and will complain if forced to use the babel-loader of Storybook).
  • Try removing these extra devDependencies if you upgrade Storybook or Create React App.

LinguiJS

• "babel-core": "^7.0.0-bridge.0" is needed for js-lingui lingui extract command (who runs Babel on source files).

Drag'n'drop handling

react-dnd is used by react-mosaic-component and react-sortable-tree (but not react-sortable-hoc). Both must be using the same versions of react-dnd and react-dnd-html5-backend. Otherwise, you get blanks/not rendered components.

You can check if there is only one version of a package by doing npm ls or yarn why:

• yarn why react-dnd
• npm ls webpack

Latest versions of react-sortable-hoc seems to be breaking the lists. The exact version in which this occurs was not determined.

Various fixes

• react-mosaic-component is a custom version where react-dnd was simply upgraded to version 7.7.0
• @lingui/react is a version where Flow definitions have been fixed.
• pixi-simple-gesture is a version where an extra check for undefined has been added to touchStart in pan.js, following traces of errors that have been inspected (though the bug could not be reproduced - but better be safe).
