Motivation\n\nWhen debugging or building examples for React component libraries, I often want to use a component to calls [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) on the React props object, so I can display that object in the browser.\n\n## Installation\n\n```\nnpm install react-stringify\n```\n\n## Examples\n\nSee [this CodeSandbox](https://codesandbox.io/s/v6104mmnyl) for an in-browser example.\n\n## Usage\n\nBasic usage is as follows:\n\n```js\nimport React from 'react'\nimport ReactDOM from 'react-dom'\nimport Stringify from 'react-stringify'\n\nconst Example = props =\u003e \u003cStringify value={props} /\u003e\n\nReactDOM.render(\u003cExample a={1} b={2} c={3} /\u003e, document.getElementById('app'))\n\n// =\u003e\n//\n// \u003cpre\u003e{\n//   \"a\": 1,\n//   \"b\": 2,\n//   \"c\": 3\n// }\u003c/pre\u003e\n```\n\nAs seen in the previous example, `Stringify` will stringify the `value` prop. If you don't pass it one, or `value` is undefined, it will return `null` (in other words, render nothing).\n\n`Stringify` supports a `space` prop. The default is two spaces, but you could use tabs (`'\\t'`) or something like this if you're feeling wild:\n\n```js\n\u003cStringify value={{ foo: 'foo', bar: 'bar' }} space=\"💩\" /\u003e\n\n// =\u003e\n//\n// \u003cpre\u003e{\n// 💩💩\"foo\": \"foo\",\n// 💩💩\"bar\": \"bar\"\n// }\u003c/pre\u003e\n```\n\nBy default, `JSON.stringify()` ignores functions. If you would like to stringify your object with functions, try the following `replacer` prop:\n\n```js\n\u003cStringify\n  value={{ foo: () =\u003e 'foo', bar: 'bar' }}\n  replacer={(key, value) =\u003e {\n    return typeof value === 'function' ? '[Function]' : value\n  }}\n/\u003e\n\n// =\u003e\n//\n// \u003cpre\u003e{\n//   \"foo\": \"[Function]\",\n//   \"bar\": \"bar\"\n// }\u003c/pre\u003e\n```\n\n`Stringify` renders the output of `JSON.stringify()` in `\u003cpre\u003e` tag by default, but you can override this by supplying any of the following render props: `component`, `render`, or `children`. See the following example and/or the [`@macklinu/render-props`](https://github.com/macklinu/render-props) README for more information.\n\n```js\n\u003cStringify\n  value={{ a: 1, b: 2, c: 3 }}\n  render={string =\u003e {\n    return (\n      \u003cdiv\u003e\n        \u003cspan\u003eMy Custom Render Function\u003c/span\u003e\n        \u003cpre\u003e{string}\u003c/pre\u003e\n      \u003c/div\u003e\n    )\n  }}\n/\u003e\n\n// =\u003e\n//\n// \u003cdiv\u003e\n//   \u003cspan\u003eMy Custom Render Function\u003c/span\u003e\n//   \u003cpre\u003e{\n//     \"foo\": \"foo\",\n//     \"bar\": \"bar\"\n//   }\u003c/pre\u003e\n// \u003c/div\u003e\n```\n\n## API Reference\n\n### `Stringify`\n\nThis component accepts the following props, which are simply passed through to [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify):\n\n* `value`\n* `replacer`\n* `space`\n\nThe [MDN `JSON.stringify()` parameter documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) explains what valid parameters types are and their default values.\n\nThe `Stringify` component also accepts the following render props:\n\n* `component`\n* `render`\n* `children`\n\nSee the [`@macklinu/render-props`](https://github.com/macklinu/render-props#api-reference) README documentation for more information.\n\n## Contributors\n\nThanks goes to these wonderful people ([emoji key](https://github.com/kentcdodds/all-contributors#emoji-key)):\n\n\u003c!-- ALL-CONTRIBUTORS-LIST:START - Do not remove or modify this section --\u003e\n\n\u003c!-- prettier-ignore --\u003e\n| [\u003cimg src=\"https://avatars1.githubusercontent.com/u/2344137?v=4\" width=\"100px;\"/\u003e\u003cbr /\u003e\u003csub\u003e\u003cb\u003eMacklin Underdown\u003c/b\u003e\u003c/sub\u003e](http://macklin.underdown.me)\u003cbr /\u003e[💻](https://github.com/macklinu/react-stringify/commits?author=macklinu \"Code\") [⚠️](https://github.com/macklinu/react-stringify/commits?author=macklinu \"Tests\") [📖](https://github.com/macklinu/react-stringify/commits?author=macklinu \"Documentation\") |\n| :---: |\n\n\u003c!-- ALL-CONTRIBUTORS-LIST:END --\u003e\n\nThis project follows the [all-contributors](https://github.com/kentcdodds/all-contributors) specification.
