This is a React project template using webpack for Spck for NodeJS. This project template was made with the help of createapp.dev.
Pressing the ▶ button will call the command build in package.json. If dist/bundle.js file does not exist, it indicates this may be the first run and install-dep in package.json will be called. The spck.config.json file controls which command to call when pressing ▶ (which can be modified in Run Settings).
Some packages like webpack, typescript, babel, react, ts-loader have been installed globally to save space, unfortunately other packages do not work when installed globally and must be installed in the project folder such as @babel/preset-env, and css-loader.
The task build creates a development build of the project and generates:
dist/bundle.js
When build finishes, the preview window will launch.
Due to security restrictions in Android, execute permissions on write-allowed storage is likely forbidden on most stock devices. This prevents some npm scripts from working properly as npm run rely on the use of sh which requires exec permissions.
The node program is also built as a shared library for compatibility with future versions of Android and can only be accessed from the terminal and not sh.
For these reasons, using npm run ... will not work from the terminal, but entering the command (webpack) directly in the terminal will work.
On external storage and SD cards, it is commonly using FAT32 or exFAT filesystems. These filesystems do not support symbolic links which is why npm dependencies that uses symlinks (mostly npm dependencies with command line usage symlinks) will fail on external storage.
Add the --no-bin-links option to npm install to prevent creation of symlinks.
npm i @babel/preset-env --no-bin-links
