[Workers are important to use][when workers] as the main thread is already overloaded, especially on slower or older devices.\n\nThis plugin takes care of shimming module support in workers and allows you to use `new Worker()`.\n\nOMT is the result of merging loadz0r and workz0r.\n\n## Usage\n\nI set up [a gist] to show a full setup with OMT.\n\n### Config\n\n```js\n// rollup.config.js\nimport OMT from \"@surma/rollup-plugin-off-main-thread\";\n\nexport default {\n input: [\"src/main.js\"],\n output: {\n dir: \"dist\",\n // You _must_ use either “amd” or “esm” as your format.\n // But note that only very few browsers have native support for\n // modules in workers.\n format: \"amd\"\n },\n plugins: [OMT()]\n};\n```\n\n### Auto bundling\n\nIn your project's code:\n\n```js\nconst worker = new Worker(\"./worker.js\", { type: \"module\" });\n```\n\nThis will just work.\n\n### Importing workers as URLs\n\nIf your worker constructor doesn't match `workerRegexp` (see options below), you might find it easier to import the worker as a URL. In your project's code:\n\n```js\nimport workerURL from \"omt:./worker.js\";\nimport paintWorkletURL from \"omt:./paint-worklet.js\";\n\nconst worker = new Worker(workerURL, { name: \"main-worker\" });\nCSS.paintWorklet.addModule(paintWorkletURL);\n```\n\n`./worker.js` and `./paint-worklet.js` will be added to the output as chunks.\n\n## Options\n\n```js\n{\n // ...\n plugins: [OMT(options)];\n}\n```\n\n- `loader`: A string containing the EJS template for the amd loader. If `undefined`, OMT will use `loader.ejs`.\n- `useEval`: Use `fetch()` + `eval()` to load dependencies instead of `
