Clusterio #984 converted its packages to ESM, so a CommonJS plugin can no longer import @clusterio/lib and plugin entrypoints must name the full file. Every package gets "type": "module", entrypoints and relative imports carry the .js extension, and the webpack configs become .cjs as webpack-cli loads them with require. tsconfig.node.json moves from node16 to nodenext to match clusterio, which needs it for the JSON import attributes in its sources. The tap tests and the shared test helpers use import and import.meta.dirname. The test scripts pass --type-strip-only so tap leaves lib's .ts subpath imports to Node's own type stripping, as its TypeScript loader compiled them without a default export. The lua runner resolves fengari from the test file it is given, since a bare import from the shared test directory does not reach the plugin's devDependencies.

/**

|
* Run one lua test file in its own lua state and return its results.
|
|
*
|
|
* The state is created here, on first use by the caller, so every test file
|
|
* gets an independent set of stubs. Three chunks run in order, each taking one
|
|
* argument and returning one value:
|
|
*
|
|
* 1. The plugin's env.lua, receiving this directory so it can load the shared
|
|
* stubs and framework, returning its environment module.
|
|
* 2. The test file, receiving the environment module, declaring its tests.
|
|
* 3. The tests then run, each against a fresh environment, and the results
|
|
* are returned as JSON.
|
|
*
|
|
* @param {string} envFile - Absolute path of the plugin's test/lua/env.lua.
|
|
* @param {string} testFile - Absolute path of the lua test file to run.
|
|
* @returns {{ name: string, ok: boolean, detail?: string }[]}
