## [v3.0.0](https://github.com/reactjs/reselect/releases/tag/v3.0.0) - 2017/03/24
|
|
|
|
### New Features
|
|
|
|
Performance improvements (thanks to @johnhaley81)
|
|
Updated Typescript typings (thanks to everyone who helped)
|
|
|
|
### Breaking Changes
|
|
|
|
For performance reasons, a selector is now not recalculated if its input is equal by reference (`===`).
|
|
|
|
#### Example:
|
|
|
|
```js
|
|
import { createSelector } from 'reselect';
|
|
|
|
const mySelector = createSelector(
|
|
state => state.values.filter(val => val < 5),
|
|
values => {
|
|
console.log('calling..')
|
|
return values.reduce((acc, val) => acc + val, 0)
|
|
}
|
|
)
|
|
|
|
var createSelector = require('./dist/reselect.js').createSelector;
|
|
|
|
const mySelector = createSelector(
|
|
state => state.values.filter(val => val < 5),
|
|
values => {
|
|
console.log('calling..')
|
|
return values.reduce((acc, val) => acc + val, 0)
|
|
}
|
|
)
|
|
|
|
var state1 = {values: [1,2,3,4,5,6,7,8,9]};
|
|
console.log(mySelector(state1));
|
|
state1.values = [3,4,5,6,7,8,9];
|
|
console.log(mySelector(state1));
|
|
var state2 = {values: [1,2,3,4,5,6,7,8,9]};
|
|
console.log(mySelector(state2));
|
|
var state3 = {values: [3,4,5,6,7]};
|
|
console.log(mySelector(state3));
|
|
```
|
|
|
|

## [v2.0.0](https://github.com/reactjs/reselect/releases/tag/v2.0.0) - 2015/10/02
|
|
|
|
### Breaking Changes
|
|
|
|
#### `createSelector`, `createStructuredSelector`, and custom selector creators check arguments
|
|
|
|
Input selectors are now verified to be functions during selector creation. If verification fails an error is thrown, allowing for a useful stack trace
|
|
|
|
There is a small chance that this could cause a breaking change in code that contains a faulty selector that is never called.
|
|
|
|
## [v1.1.0](https://github.com/reactjs/reselect/releases/tag/v1.1.0) - 2015/09/16
|
|
|
|
### New features
|
|
|
|
#### `createStructuredSelector`
|
|
|
|
`createStructuredSelector` is a convenience function that helps with a common pattern when using Reselect. The selector passed to a connect decorator often just takes other selectors and maps them to keys in an object:
|
|
|
|
```js
|
|
const mySelectorA = state => state.a;
|
|
const mySelectorB = state => state.b;
|
|
|
|
const structuredSelector = createSelector(
|
|
mySelectorA,
|
|
mySelectorB,
|
|
mySelectorC,
|
|
(a, b, c) => ({
|
|
a,
|
|
b,
|
|
c
|
|
})
|
|
);
|
|
```
|
|
|
|
`createStructuredSelector` takes an object whose properties are input-selectors and returns a structured selector. The structured selector returns an object with the same keys as the `inputSelectors` argument, but with the selectors replaced with their values.
|
|
|
|
```js
|
|
const mySelectorA = state => state.a;
|
|
const mySelectorB = state => state.b;
|
|
|
|
const structuredSelector = createStructuredSelector({
|
|
x: mySelectorA,
|
|
y: mySelectorB
|
|
});
|
|
|
|
const result = structuredSelector({a: 1, b: 2}); // will produce {x: 1, y: 2}
|
|
```
|
|
|
|

|
|
## [v1.0.0-alpha](https://github.com/reactjs/reselect/releases/tag/v1.0.0-alpha) - 2015/09/01
|
|
|
|
### Breaking Changes
|
|
|
|
`createSelectorCreator` takes a user specified memoize function instead of a custom `valueEqualsFunc`.
|
|
|
|
#### Before
|
|
|
|
```js
|
|
import { isEqual } from 'lodash';
|
|
import { createSelectorCreator } from 'reselect';
|
|
|
|
const deepEqualsSelectorCreator = createSelectorCreator(isEqual);
|
|
```
|
|
|
|
#### After
|
|
|
|
```js
|
|
import { isEqual } from 'lodash';
|
|
import { createSelectorCreator, defaultMemoize } from 'reselect';
|
|
|
|
const deepEqualsSelectorCreator = createSelectorCreator(
|
|
defaultMemoize,
|
|
isEqual
|
|
);
|
|
```
|
|
|
|
### New features
|
|
|
|
#### Variadic Dependencies
|
|
|
|
Selector creators can receive a variadic number of dependencies as well as an array of dependencies.
|
|
|
|
#### Before
|
|
|
|
```js
|
|
const selector = createSelector(
|
|
[state => state.a, state => state.b],
|
|
(a, b) => a * b
|
|
);
|
|
```
|
|
|
|
#### After
|
|
|
|
```js
|
|
const selector = createSelector(
|
|
state => state.a,
|
|
state => state.b,
|
|
(a, b) => a * b
|
|
);
|
|
```
|
|
|
|
#### Access `ownProps` in Selector
|
|
|
|
Selector dependencies can receive a variadic number of parameters allowing a selector to receive `ownProps` passed from `mapToProps` in `connect`.
|
|
|
|
```js
|
|
const selector = createSelector(
|
|
(state) => state.a,
|
|
(state, props) => state.b * props.c,
|
|
(_, props) => props.d,
|
|
(a, bc, d) => a + bc + d
|
|
);
|
|
```
|
|
|
|
#### Configurable Memoize Function
|
|
|
|
```js
|
|
import { createSelectorCreator } from 'reselect';
|
|
import memoize from 'lodash.memoize';
|
|
|
|
let called = 0;
|
|
const customSelectorCreator = createSelectorCreator(memoize, JSON.stringify);
|
|
const selector = customSelectorCreator(
|
|
state => state.a,
|
|
state => state.b,
|
|
(a, b) => {
|
|
called++;
|
|
return a + b;
|
|
}
|
|
);
|
|
assert.equal(selector({a: 1, b: 2}), 3);
|
|
assert.equal(selector({a: 1, b: 2}), 3);
|
|
assert.equal(called, 1);
|
|
assert.equal(selector({a: 2, b: 3}), 5);
|
|
assert.equal(called, 2);
|
|
```
