Redux with class 😎

This small library will help typescript users use all the potential of typescript while dispatching actions.

Now those actions will be instance of classes, instead of being plain objects.

instead of

export default function(state: IState = initialState, action: any): IProfileState {
    switch (action.type) {
        case 'SOME_ACTION':
            // Compiler has no idea what action is.
            break;
    }
    return state;
}

export function doSomeAction() {
    return {
        type: 'SOME_ACTION',
        payload: 'foo',
    };
}

you can write

import { ActionWrapper } from 'redux-with-class';
export default function(state: IState = initialState, wrapper: ActionWrapper): IProfileState {
    const action = wrapper.action;
    if (action instanceof SomeAction) {
        // Now compiler knows what is wrapper.action.
        const foo = action.payload;
        // the compiler knows foo is a string.
    }
    return state;
}

export function doSomeAction() {
    return new SomeAction('foo');
}

class SomeAction {
    constructor(public payload: string) {}
    type = 'SOME_ACTION';
}

This will ensure everything is statically typed.

Installation

npm install --save redux-with-class

And then, in your store config:

import { convertToPlainAction } from 'redux-with-class';

const store = createStore(rootReducer, undefined, applyMiddleware(/* other middlewares here */ convertToPlainAction));
