React Redux LifeCycles

Store lifeCycle callbacks (will be extended in future):

storeDidUpdate(storeState: YourStoreStateInterface): void {}
storeDidUpdateState(currentStoreState: YourStoreStateInterface, prevStoreState: YourStoreStateInterface): void {}

Install

Via npm

npm install --save react-redux-lifecycles

Usage

As decorator:

import * as React from "react";

import { connect } from "react-redux";
import { withLifeCycles } from "react-redux-lifecycles";

@withLifeCycles()
@connect(mapStateToProps, mapDispatchToProps, mergeOptions, { withRef: true })
export class Component extends React.Component {}

As HOC:

import * as React from "react";

import { connect } from "react-redux";
import { withLifeCycles } from "react-redux-lifecycles";

class Component extends React.Component {}

export default withLifeCycles()(connect(mapStateToProps, mapDispatchToProps, mergeOptions, { withRef: true })(Component));

Note: withLifeCycles apply as argument only connected component

Note: You must pass { withRef: true } argument to connect method

Methods

storeDidUpdate

Will called after store received new state (reducer has been executed).

To get access to storeDidUpdate method just use withLifeCycles() method without any arguments.

storeDidUpdateState

Will called after store received new specific state (reducer has been executed).

To get access to storeDidUpdateState method just use withLifeCycles() with array of strings as argument. For example:

/**
storeState: {
    field1: {
        level1: {
            level2: true
        },
        subLevel: false
    },
    field2: {
        level1: false
    },
    loading: false
}
**/

// storeDidUpdateState will be executed if one of the passed arguments changed
@withLifeCycles(["field1.level1.level2", "loading"])
@connect(mapStateToProps, mapDispatchToProps, mergeOptions, { withRef: true })
export class Component extends React.Component {
    storeDidUpdateState(currentState) {
        /**
         if reducer change only 'field2' or 'field1.subLevel' value, 'storeDidUpdateState' does not be executed
         if reducer change 'loading' or 'field1.level1.level2' value, 'storeDidUpdateState' will be executed
        **/
    }

    storeDidUpdate(currentStoreState, prevStoreState) {
        // Always executing after store received new state
    }
}
