Migrate the usage of CommonJS specific code and imports to ESM. Roughly
summarised this:
- Changes all require() calls to import statement or expressions.
- Changes usage of module.exports to export statements.
- Replaces require.resolve with import.meta.resolve.
- Replaces conditional imports with conditional subpath imports.
- Replaces module === require.main with import.meta.main.
- Adds the full filename with extention to all relative imports.
- Changes all usage of __dirname and __filename to their import.meta
equivalents.
- Sets "type": "module" in package.json files.
- Removes usage of "use strict".
- Adds .ts an an alias of .js for the webpack build.
Due to differences in how require and import resolves files the plugin
entrypoints will have to include the filename and extension after this
migration in order to work.
The lib library was written with the assumption that there's only one
copy of it in the whole application and everything imports that one
copy. Unfortunately there are quite a few circumstances were package
managers end up installing multiple copies of lib and then different
parts use different versions of the library.
This causes Clusterio to break with strange and hard to track down
errors. Most notably permissions and link messages for a plugin may get
registered to one copy of lib while the controller uses a different copy
and thus does not see or register that what the plugin added exists.
Detect this condition when importing @clusterio/lib and throw an error
when it has been imported twice in order to prevent the broken
installation from causing future hard to debug issues.
