License: MIT npm package Build Status Greenkeeper badge PropType validators that work with Immutable.js. Forked from react-immutable-proptypes.


Usage is simple, they work with and like any PropType.* validator. ```js import PropTypes from 'prop-types'; import ImmutablePropTypes from 'immutable-prop-types'; class MyReactComponent extends React.Component { // ... } MyReactComponent.propTypes = { myRequiredImmutableList: ImmutablePropTypes.listOf(
someNumberProp: PropTypes.number.isRequired
).isRequired }; ``` Convenience helpers for "primitive" Immutable.js objects: ```js propTypes: { oldListTypeChecker: PropTypes.instanceOf(Immutable.List), anotherWay: ImmutablePropTypes.list, requiredList: ImmutablePropTypes.list.isRequired, mapsToo:, evenIterable: ImmutablePropTypes.iterable } ```


Installing via npmjs ```bash npm install --save immutable-prop-types ```


Immutable prop types has:
  • Primitive Types
```js ImmutablePropTypes.list // Immutable.List.isList // Immutable.Map.isMap ImmutablePropTypes.orderedMap // Immutable.OrderedMap.isOrderedMap ImmutablePropTypes.set // Immutable.Set.isSet ImmutablePropTypes.orderedSet // Immutable.OrderedSet.isOrderedSet ImmutablePropTypes.stack // Immutable.Stack.isStack ImmutablePropTypes.seq // Immutable.Seq.isSeq ImmutablePropTypes.iterable // Immutable.Iterable.isIterable ImmutablePropTypes.record // instanceof Record ImmutablePropTypes.contains // Immutable.Iterable.isIterable - contains(shape) ImmutablePropTypes.mapContains // Immutable.Map.isMap - contains(shape) ```
  • ImmutablePropTypes.contains (formerly shape) is based on PropTypes.shape and will try to work with any Immutable.Iterable. In my usage it is the most used validator, as I'm often trying to validate that a map has certain properties with certain values.
```es6 // ... aMap: ImmutablePropTypes.contains({ aList: ImmutablePropTypes.contains({
0: PropTypes.number,
1: PropTypes.string,
2: PropTypes.number.isRequired,
}).isRequired, }) // ... 1, 'two', 3})} /> ```
  • ImmutablePropTypes.listOf is based on PropTypes.array and is specific to Immutable.List.
  • ImmutablePropTypes.mapOf allows you to control both map values and keys (in Immutable.Map, keys could be anything including another Immutable collections). It accepts two arguments - first one for values, second one for keys (optional). If you are interested in validation of keys only, just pass PropTypes.any as the first argument.
```es6 // ... aMap: ImmutablePropTypes.mapOf( PropTypes.any, // validation for values ImmutablePropTypes.mapContains({ // validation for keys
a: PropTypes.number.isRequired,
b: PropTypes.string
}) ) // ... const aMap = Immutable.Map( Immutable.Map({a: 1, b: '2'}), 'foo', Immutable.Map({a: 3}), 1, '2', 3 ); ```
  • ImmutablePropTypes.orderedMapOf is basically the same as mapOf, but it is specific to Immutable.OrderedMap.
  • ImmutablePropTypes.orderedSetOf is basically the same as listOf, but it is specific to Immutable.OrderedSet.
  • ImmutablePropTypes.stackOf is basically the same as listOf, but it is specific to Immutable.Stack.
  • ImmutablePropTypes.iterableOf is the generic form of listOf/mapOf. It is useful when there is no need to validate anything other than Immutable.js compatible (ie. Immutable.Iterable). Continue to use listOf and/or mapOf when you know the type.
  • ImmutablePropTypes.recordOf is like contains, except it operates on Record properties.
```js // ... aRecord: ImmutablePropTypes.recordOf({ keyA: PropTypes.string, keyB: ImmutablePropTypes.list.isRequired }) // ... ```
  • ImmutablePropTypes.mapContains is based on PropTypes.shape and will only work with Immutable.Map.
```es6 // ... aMap: ImmutablePropTypes.mapContains({ aList: ImmutablePropTypes.list.isRequired, }) // ... 1, 2})} /> ``` These two validators cover the output of Immutable.fromJS on standard JSON data sources.
