Wimdu](https://img.shields.io/badge/developed%20at-Wimdu-FCAF16.svg?style=flat-square)](http://tech.wimdu.com/)\n\n\u003e **Compose small testable functions to modify props for components.**\n\n## Install\n\n```shell\n$ npm install transform-props-with --save\n```\n\nor with [Yarn](https://github.com/yarnpkg/yarn)\n\n```shell\n$ yarn add transform-props-with\n```\n\n## Usage\n\n```js\nimport tx from 'transform-props-with'\n\nimport BaseComponent from './base-component'\n\nconst doubleSize = (oldProps) =\u003e {\n  const { size, ...props } = oldProps\n\n  return {\n    size: size * 2,\n    ...props\n  }\n}\n\nconst EnhancedComponent = tx(doubleSize)(BaseComponent)\n\nReactDOM.render(\u003cEnhancedComponent size={100} /\u003e, node)\n// Would render \u003cBaseComponent size={200} /\u003e\n```\n\nSee the full [API documentation](docs/api.md) for details.\n\n### Merge objects\n\nPass an object to merge it with provided props automatically.\n\n```js\nconst EnhancedComponent = tx({ stars: 10 })(BaseComponent)\n\nReactDOM.render(\u003cEnhancedComponent size={100} /\u003e, node)\n// Would render \u003cBaseComponent size={100} stars={ 10 } /\u003e\n\n```\n\nNote: this is *not* a deep merge. It is equal to this transformation:\n\n```js\nconst setStarsTo10 = (oldProps) =\u003e Object.assign({}, oldProps, { stars: 10 })\n```\n\n### Multiple transformations\n\nPass an array of transformations to the function, and they will all be combined\nto a single transformation *left to right*.\n\nIn the following example, `addFive` would be applied first, and `doubleSize`\nwill be called with props returned by it.\n\n```js\nconst EnhancedComponent =\n  tx([ addFive, doubleSize ])(BaseComponent)\n```\n\nOf course, transformations and object merges can be mixed.\n\n```js\nconst EnhancedComponent =\n  tx([ addFive, { stars: 10 }, doubleSize ])(BaseComponent)\n```\n\n### Refs to Components\n\nReact enables to get references to the DOM elements using `ref` props, cf. [documentation](https://facebook.github.io/react/docs/more-about-refs.html#the-ref-callback-attribute). When passed to an enhanced component this would point to the *wrapper*. The library will rename `__ref` to `ref` so the developer can access the DOM element of the inner component.\n\n## Examples\n\n* [Change a prop value](examples/double-size.js)\n* [Wrap general component](examples/wrap-general-component.js)\n* [Switch two props](examples/switch-foo-bar.js)\n* [Track click](examples/track-click.js) (decorating `onClick`)\n* [Build BEM components](https://github.com/agudulin/dumb-bem#usage) using [dumb-bem](https://www.npmjs.com/package/dumb-bem)\n\n### Notes\n\n* *Transform Props With* returns a stateless functional component; these were introduced in\nReact v0.14.0 ([release notes](https://facebook.github.io/react/blog/2015/10/07/react-v0.14.html)).\n\n* Polyfill for\n[Array.prototype.reduce] (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce)\nmight be needed to support older browsers.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobinpokorny%2Ftransform-props-with","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frobinpokorny%2Ftransform-props-with","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobinpokorny%2Ftransform-props-with/lists"}
