  "readme": "# jest-worker\n\nModule for executing heavy tasks under forked processes in parallel, by\nproviding a `Promise` based interface, minimum overhead, and bound workers.\n\nThe module works by providing an absolute path of the module to be loaded in all\nforked processes. Files relative to a node module are also accepted. All methods\nare exposed on the parent process as promises, so they can be `await`'ed. Child\n(worker) methods can either be synchronous or asynchronous.\n\nThe module also implements support for bound workers. Binding a worker means\nthat, based on certain parameters, the same task will always be executed by the\nsame worker. The way bound workers work is by using the returned string of the\n`computeWorkerKey` method. If the string was used before for a task, the call\nwill be queued to the related worker that processed the task earlier; if not, it\nwill be executed by the first available worker, then sticked to the worker that\nexecuted it; so the next time it will be processed by the same worker. If you\nhave no preference on the worker executing the task, but you have defined a\n`computeWorkerKey` method because you want _some_ of the tasks to be sticked,\nyou can return `null` from it.\n\nThe list of exposed methods can be explicitly provided via the `exposedMethods`\noption. If it is not provided, it will be obtained by requiring the child module\ninto the main process, and analyzed via reflection. Check the \"minimal example\"\nsection for a valid one.\n\n## Install\n\n```sh\n$ yarn add jest-worker\n```\n\n## Example\n\nThis example covers the minimal usage:\n\n### File `parent.js`\n\n```javascript\nimport Worker from 'jest-worker';\n\nasync function main() {\n  const worker = new Worker(require.resolve('./worker'));\n  const result = await worker.hello('Alice'); // \"Hello, Alice\"\n}\n\nmain();\n```\n\n### File `worker.js`\n\n```javascript\nexport function hello(param) {\n  return 'Hello, ' + param;\n}\n```\n\n## API\n\nThe only exposed method is a constructor (`Worker`) that is initialized by\npassing the worker path, plus an options object.\n\n### `workerPath: string` (required)\n\nNode module name or absolute path of the file to be loaded in the child\nprocesses. Use `require.resolve` to transform a relative path into an absolute\none.\n\n### `options: Object` (optional)\n\n#### `exposedMethods: $ReadOnlyArray<string>` (optional)\n\nList of method names that can be called on the child processes from the parent\nprocess. You cannot expose any method named like a public `Worker` method, or\nstarting with `_`. If you use method auto-discovery, then these methods will not\nbe exposed, even if they exist.\n\n#### `numWorkers: number` (optional)\n\nAmount of workers to spwan. Defaults to the number of CPUs minus 1.\n\n#### `maxRetries: number` (optional)\n\nMaximum amount of times that a dead child can be re-spawned, per call. Defaults\nto `3`, pass `Infinity` to allow endless retries.\n\n#### `forkOptions: Object` (optional)\n\nAllow customizing all options passed to `childProcess.fork`. By default, some\nvalues are set (`cwd`, `env` and `execArgv`), but you can override them and\ncustomize the rest. For a list of valid values, check\n[the Node documentation](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options).\n\n#### `computeWorkerKey: (method: string, ...args: Array<any>) => ?string` (optional)\n\nEvery time a method exposed via the API is called, `computeWorkerKey` is also\ncalled in order to bound the call to a worker. This is useful for workers that\nare able to cache the result or part of it. You bound calls to a worker by\nmaking `computeWorkerKey` return the same identifier for all different calls. If\nyou do not want to bind the call to any worker, return `null`.\n\nThe callback you provide is called with the method name, plus all the rest of\nthe arguments of the call. Thus, you have full control to decide what to return.\nCheck a practical example on bound workers under the \"bound worker usage\"\nsection.\n\nBy default, no pro
