I am available for full-time remote positions.\n\n# Features\n\n- Sets an error's\n  [prototype, name and constructor](#seterrorclasserror-errorclass)\n- Update the [error's `stack`](#errorstack) with its new `name`\n- Handles [invalid errors](#invalid-errors)\n\n# Example\n\n```js\nimport setErrorClass from 'set-error-class'\n\nconst typeError = new TypeError('test')\nconsole.log(typeError instanceof TypeError) // true\nconsole.log(typeError.name) // 'TypeError'\nconsole.log(typeError.constructor) // TypeError\nconsole.log(typeError.stack) // TypeError: test ...\n\nconst rangeError = setErrorClass(typeError, RangeError)\nconsole.log(rangeError === typeError) // true\nconsole.log(rangeError instanceof RangeError) // true\nconsole.log(rangeError.name) // 'RangeError'\nconsole.log(rangeError.constructor) // RangeError\nconsole.log(rangeError.stack) // RangeError: test ...\n```\n\n# Install\n\n```bash\nnpm install set-error-class\n```\n\nThis package works in both Node.js \u003e=18.18.0 and\n[browsers](https://raw.githubusercontent.com/ehmicky/dev-tasks/main/src/browserslist).\n\nThis is an ES module. It must be loaded using\n[an `import` or `import()` statement](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c),\nnot `require()`. If TypeScript is used, it must be configured to\n[output ES modules](https://www.typescriptlang.org/docs/handbook/esm-node.html),\nnot CommonJS.\n\n# API\n\n## setErrorClass(error, ErrorClass)\n\n`error` `Error | unknown`\\\n`ErrorClass` `typeof Error`\\\n_Return value_: `Error`\n\nSets the `error`'s\n[prototype](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getPrototypeOf),\n[`name`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/name)\nand\n[`constructor`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/constructor).\n\n# Usage\n\n## Invalid errors\n\n`error` is returned. If `error` is not an `Error` instance, it is converted to\none.\n\n## `error.stack`\n\nIn V8 (Chrome, Node.js, Deno, etc.),\n[`error.stack`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/stack)\nincludes\n[`error.name`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/message).\nIt is updated accordingly.\n\n## Error constructors\n\n`ErrorClass` is assigned to `error`, but its constructor is not called. In some\ninstances, this might lead to invalid errors. If `ErrorClass`'s constructor is\ndoing anything significant, that logic should be performed on `error` as well.\n\n# Related projects\n\n- [`modern-errors`](https://github.com/ehmicky/modern-errors): Handle errors in\n  a simple, stable, consistent way\n- [`error-custom-class`](https://github.com/ehmicky/error-custom-class): Create\n  one error class\n- [`error-class-utils`](https://github.com/ehmicky/error-class-utils): Utilities\n  to properly create error classes\n- [`error-serializer`](https://github.com/ehmicky/error-serializer): Convert\n  errors to/from plain objects\n- [`normalize-exception`](https://github.com/ehmicky/normalize-exception):\n  Normalize exceptions/errors\n- [`is-error-instance`](https://github.com/ehmicky/is-error-instance): Check if\n  a value is an `Error` instance\n- [`set-error-message`](https://github.com/ehmicky/set-error-message): Properly\n  update an error's message\n- [`wrap-error-message`](https://github.com/ehmicky/wrap-error-message):\n  Properly wrap an error's message\n- [`set-error-props`](https://github.com/ehmicky/set-error-props): Properly\n  update an error's properties\n- [`set-error-stack`](https://github.com/ehmicky/set-error-stack): Properly\n  update an error's stack\n- [`merge-error-cause`](https://github.com/ehmicky/merge-error-cause): Merge an\n  error with its `cause`\n- [`error-cause-polyfill`](https://github.com/ehmicky/error-cause-polyfill):\n  Polyfill `error.cause`\n- [`handle-cli-error`](https://github.com/ehmicky/handle-cli-error): 💣 Error\n  handler for CLI applications 💥\n- [`log-process-errors`](https://github.com/ehmicky/log-process-errors): Show\n  some ❤ to Node.js process errors\n- [`error-http-response`](https://github.com/ehmicky/error-http-response):\n  Create HTTP error responses\n- [`winston-error-format`](https://github.com/ehmicky/winston-error-format): Log\n  errors with Winston\n\n# Support\n\nFor any question, _don't hesitate_ to [submit an issue on GitHub](../../issues).\n\nEveryone is welcome regardless of personal background.
