Since all connectors have a same pattern for package.json, here we leverage several techniques to avoid annoying copy-pastes:
When pnpm i
The "pnpm:devPreinstall" script in the project root executes templates/sync-preset.js that:
Check every connectors's package.json to see if there's any unexpected keys
Sync templates/package.json by REPLACING every template key (except dependency keys) in the current package.json with the value from the template package.json
Copies all config files to every connector directory
The hook in .pnpmfile.cjs of the project root merges dependency fields for every connector
Also we can update arbitrary fields in this hook, we still need to keep non-dependency fields in the connector's package.json since the hook only takes affect during pnpm i.
Caution
Workspace dependencies should be defined in connector's package.json (not template) in order to let PNPM correctly resolves the workspace dependency tree;
Add a new custom field
Head to templates/sync-preset.js and update allowedCustomKeys.
