react-nanny v2.15.0

react-nanny

Utils to manage your React Children; find and filter children by type or custom function, enforce child content, and more!

react-nanny doesn't have any dependencies. However, it does have a peer dependency of "react": ">=16.0.0" which you most likely satisfy if you're the kind of person who's looking for utils for React children.

import React from 'react';
import { getChildrenByType, getChildren } from 'react-nanny';
import Item from './Item';

export const ToDoList ({ children }) => {
  // Get all children of type Item
  const items = getChildrenByType(children, [Item]);

  // Find all incomplete and complete Items
  const incomplete = getChildren(items, child => !child.props.completed);
  const completed = getChildren(items, child => child.props.completed);

  return (
    <>
      <div>
        <h3>To Do</h3>
        <ul>
          {incomplete}
        </ul>
      </div>
      <div>
        <h3>Completed</h3>
        <ul>
          {completed}
        </ul>
      </div>
    </>
  );
};

import MyComponent from './MyComponent';

const child = getChildByType(children, [MyComponent]);

import { getChildByType, removeChildrenByType, typeOfComponent } from 'react-nanny';
import MyComponent from './MyComponent';

const child = getChildByType(children, [MyComponent]);
...
removeChildrenByType(children, [typeOfComponent(child)]);

import { getChildByType } from 'react-nanny';

getChildByType(children, ['div']);

import React from 'react';

const Hello = ({ __TYPE }) => <div>Hello World!</div>;

Hello.defaultProps = {
  __TYPE: 'Hello',
};

import { getChildByType } from 'react-nanny';

getChildByType(children, ['Hello']);

import { getChildByType } from 'react-nanny';

getChildByType(children, ['Hello'], { customTypeKey: 'CUSTOM' });
