wrap an error's message.\n\n# Hire me\n\nPlease\n[reach out](https://www.linkedin.com/feed/update/urn:li:activity:7117265228068716545/)\nif you're looking for a Node.js API or CLI engineer (11 years of experience).\nMost recently I have been [Netlify Build](https://github.com/netlify/build)'s\nand [Netlify Plugins](https://www.netlify.com/products/build/plugins/)'\ntechnical lead for 2.5 years. I am available for full-time remote positions.\n\n# Features\n\n- Handle\n  [invalid errors](https://github.com/ehmicky/normalize-exception#features)\n- [Update `error.stack`](https://github.com/ehmicky/set-error-message) with the\n  new error message\n- Either append or prepend the new message\n- Trim whitespaces\n\n# Example\n\n```js\nimport wrapErrorMessage from 'wrap-error-message'\n\nwrapErrorMessage(new Error('Message.'), 'Additional message.')\n// Error: Message.\n// Additional message.\n\nwrapErrorMessage(new Error('Message.'), 'Additional message:')\n// Error: Additional message: Message.\n\nwrapErrorMessage(new Error('Message.'), 'Additional message:\\n')\n// Error: Additional message:\n// Message.\n\nwrapErrorMessage(new Error('Message.'), '')\n// Error: Message.\n\nconst invalidError = 'Message.'\nwrapErrorMessage(invalidError, 'Additional message.')\n// Error: Message.\n// Additional message.\n\nwrapErrorMessage(new Error('  Message with spaces  '), '  Additional message  ')\n// Error: Message with spaces\n// Additional message\n```\n\n# Install\n\n```bash\nnpm install wrap-error-message\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## wrapErrorMessage(error, message)\n\n`error` `Error | any`\\\n`message` `string`\\\n_Return value_: `Error`\n\nAppends `message` to `error.message`. If `message` ends with `:` or `:\\n`,\nprepends it instead.\n\nReturns `error`. If `error` is not an `Error` instance, it is converted to one.\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- [`merge-error-cause`](https://github.com/ehmicky/merge-error-cause): Merge an\n  error with its `cause`\n- [`set-error-class`](https://github.com/ehmicky/set-error-class): Properly\n  update an error's class\n- [`set-error-message`](https://github.com/ehmicky/set-error-message): Properly\n  update 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- [`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.
