find yourself making conditionals\ncomponents quite a lot of times. And they're always the same: a component which\nupon a set of conditions may render or just return null (or short-circuit it).\n\nHere comes Mayre (May**b**e render)! A very simple and super light (2kb)\ncomponent to tackle this issue from the `jsx` side.\n\nCompatible with *React*, *React-Native* and *ReactVR*.\n\n### Usage\n\n#### Maybe\n\nThere are three props you can use: `of`, `when` and `with`.\n\n```js\n\u003cMayre\n  of={MyComponent}\n  when={props.something \u003e 10}\n  with={{ some: 'thing' }}\n/\u003e\n```\n\nNote that `of` can be a component instance or declaration. And when can be boolean\nor a function.\n\n```js\n\u003cMayre\n  of={\u003cp\u003eSomething\u003c/p\u003e}\n  when={() =\u003e checkWhatever()}\n/\u003e\n```\n\n#### Either\n\nBut not only this! Conditional rendering isn't only about mount this component\nor not. We can also use Mayre to render either this element or the other.\n\n```js\n\u003cMayre\n  of={\u003cp\u003eEither this\u003c/p\u003e}\n  or={\u003cp\u003eOr this one\u003c/p\u003e}\n  when={whateverCondition}\n/\u003e\n```\n\nIf a `with` prop is provided it'll be applied to both of them. If you want to specify special props for each of them use `orWith`.\n\n```js\n\u003cMayre\n  of={\u003cp\u003eEither this\u003c/p\u003e}\n  or={\u003cp\u003eOr this one\u003c/p\u003e}\n  when={whateverCondition}\n  with={{ appliedTo: 'of' }}\n  orWith={{ appliedTo: 'this will used by or element' }}\n/\u003e\n```\n\n#### Auto props picking\n\nMost of the times the component rendered by Mayre is a subset of a bigger one.\nHence, it's using a selection of the parent props. That's why Mayre has a special\nsyntax to pick the props you need to while passing them down.\n\n```js\n\u003cMayre\n  of={MyComponent}\n  when={props.something \u003e 10}\n  with={[props, 'thisProps', 'andThisOther']}\n/\u003e\n```\n\nSame can be applied for `orWith` attribute.\n\n### Props\n\n| Name   | Required | Default | Type              |Comment                                 |\n|--------|----------|---------|-------------------|----------------------------------------|\n| of     | Yes      | -       | `func`, `element` | The React component to be rendered     |\n| or     | No       | `null`  | `func`, `element` | The React component rendered instead of `of`  |\n| when   | No       | `false` | `bool`, `func`    | The render condition                    |\n| with   | No       | `{}`    | `object`, `array` | Props to be passed to `of/or` component |\n| orWith | No       | `{}`    | `object`, `array` | Props to be passed to `or` component    |\n\n### Benefit\n\nStop doing this:\n\n```js\n// no more dumb render methods pollution\nconst renderSomething = (canRender, propsFromParent) =\u003e {\n  if (!canRender) return null\n\n  return \u003cSomething {...propsFromParent} /\u003e\n}\n\nconst Parent = (props) =\u003e (\n  \u003cdiv\u003e\n    {renderSomething(props.a === props.b, props)}\n  \u003c/div\u003e\n)\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsospedra%2Fmayre","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsospedra%2Fmayre","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsospedra%2Fmayre/lists"}
