Redux Genie

Made for developers creating JavaScript applications with Redux.


Redux Genie isn't a "starter kit" or a library of helper methods. It actually writes your Redux boilerplate code, either creating new files or injecting code into an existing store files. This makes the writing process easier to start, easier to manage as you progress, and less error-prone, without abstracting over the functionality of Redux itself.

The genie can be comprehensive- generating the whole Redux store from the onset of a project- or granular- creating or operating on a specific slice of state for an existing project.

npm install -g redux-genie

Check out our documentation, which includes a web app to build the initial lamp.config.yml file.


Store Declaration at the beginning of a project

To generate a store, Redux Genie's configuration file- lamp.config.yml - will need define the total store structure.

Choose from the two of the file structures outlined in the Redux FAQs: https://redux.js.org/faq/code-structure

Structure: Rails || Ducks

Define the slices of state. We refer to them as "Models", but they could also be called "Domains" (in the sense of "domain driven design"). Essentially, they are the specific way you want to organize the entities in state.

The genie automatically generates and configures all CRUD methods with separate subreducers for each Model, with Thunks linked to the Redux-Thunk middleware calling your defined API endpoints.

Structure: Rails

Models:

  - Dux:

    Slice:
      - Name: string
      - Quacking: Boolean
      - Ducklings: Object
      - Fly2Gether: Boolean

    Actions:
      - countDux
      - migrateDux
      - quackOne

    Thunks:
      - getAll: "/api/Dux"
      - getOne: "/api/Dux/:dux"

Place the lamp.config.yml file in the project root directory, then run:

genie generate store

Rails-Style

Rails-style: separate folders for “actions”, “constants”, and “reducers.”

Generated file structure:

actions
├── actions_for_Ducks.js
├── actions_for_Terminator.js
├── selectors_for_Ducks.js
└── selectors_for_Terminator.js

constants
└── action_constants.js

reducers
├── combine_reducers.js
├── reducer_for_Ducks.js
└── reducer_for_Terminator.js

store.js

Ducks-Style

“Ducks”: separate folders per Model/Domain

Generated file structure:

Ducks
├── action_constants_for_Ducks.js
├── actions_for_Ducks.js
├── reducer_for_Ducks.js
└── selectors_for_Ducks.js

Terminator
├── action_constants_for_Terminator.js
├── actions_for_Terminator.js
├── reducer_for_Terminator.js
└── selectors_for_Terminator.js

combine_reducers.js

store.js

lamp.config.yml options

Options to customize the generate call.


CRUD: false

Each model is automatically generated with CRUD methods. These can be excluded as follows:

Models:

  - Dux:

    Slice:
      - Name: string
      - Quacking: Boolean
      - Ducklings: Object
      - Fly2Gether: Boolean
    CRUD: false

Thunks: included

Thunks can be included in the same file as the actions:

Structure: Rails

Thunks: included

If "Thunks" are excluded in the model definition, they will be omitted from the generate call. These can be added later via "genie update" (see below).


Logging: false

Redux logger is wired into the store by default, but can be excluded:

Structure: Rails

Logging: false  

Example of Full Configuration File:

Structure: Ducks # Rails || Ducks

Thunks: included # thunks will be included in the same file as the actions
Logging: false  # configures logging middleware

Models:

  - Dux:

    Slice:
      - Name: string
      - Quacking: Boolean
      - Ducklings: Object
      - Fly2Gether: Boolean

    CRUD: false

    Actions:
      - countDux
      - migrateDux
      - quackOne

    Thunks:
      - getAll: "/api/Dux"
      - getOne: "/api/Dux/:dux"

  - Terminator:

    Slice:
      - WillBeBack: Boolean
      - OneLiners: Array
      - Sequels: Number

    Actions:
      - killJohnConnor
      - backInTime

    Thunks:
      - getAll: "api/terminator"
      - getOne: "api/terminator/:terminator"

CLI

genie generate

genie generate

genie connect

genie connect

Connects a React component to the store via the React-Redux library.

Must define the path to the component to be converted, the name of the component, and the models/domains to connect:

genie   connect  app/components/ExampleThree.js  ExampleThree  -m DucklingTerminator

Can connect multiple models at one time:

genie  connect  app/components/ExampleThree.js  ExampleThree   -m
DucklingTerminator -m Velociraptor -m Replicant

The genie will insert the code for the connect method into the current file, and generate an unconnected copy of the source file in the same directory.

Example:

Source file

import React from 'react';

export default function ExampleThree (props){

  const { stuff } = props;

  return (
    <div>

    </div>
  );
};

Connect call:

genie connect app/components/ExampleThree.js ExampleThree -m DucklingTerminator

Output:

import { connect } from "react-redux";

import {
  getDucklingTerminator,
  getAllDucklingTerminator,
  createDucklingTerminator,
  updateDucklingTerminator,
  deleteDucklingTerminator
} from "../../store/DucklingTerminator/actions_for_DucklingTerminator.js";

import React from "react";

function ExampleThree(props) {
  const { stuff } = props;
  return (
    <div>

    </div>
  );
}

const mapStateToProps = ({ DucklingTerminator_state }) => {
  return {
    isQuacking: DucklingTerminator_state.isQuacking,
    DucklingTerminatorList: DucklingTerminator_state.DucklingTerminatorList,
    isLoading: DucklingTerminator_state.isLoading,
    SingleDucklingTerminator: DucklingTerminator_state.SingleDucklingTerminator
  };
};

const mapDispatchToProps = dispatch => ({
  getDucklingTerminator: () => dispatch(getDucklingTerminator()),
  getAllDucklingTerminator: () => dispatch(getAllDucklingTerminator()),
  createDucklingTerminator: () => dispatch(createDucklingTerminator()),
  updateDucklingTerminator: () => dispatch(updateDucklingTerminator()),
  deleteDucklingTerminator: () => dispatch(deleteDucklingTerminator())
});

export default connect(
  mapStateToProps,
  mapDispatchToProps
)(ExampleThree);

genie update

genie update

The genie will diff the new yml config to previous version and generate any required updates.

Notes: You cannot change the file structure that was created when the store was generated.


genie add

Add directly from the command line:

genie add [-m]/[-M] <model_name> [-a] <action_name> [-t] <thunk_name>

The add command allows you to add specific properties or thunks to an existing model, or add an entirely new model with defined properties to an existing store directly from the CLI.

Examples:

Add a new model


  genie add --newmodel Terminator

  genie add -M Terminator

Add actions in new model call

  genie add --newmodel Terminator -a getIsBack -a killJohnConnor 

  without CRUD ops

  genie add --newmodel Terminator -a getIsBack --noCRUD

Add an action to specific model

  genie add --action getIsBack -model Terminator 
    
    ... or abbreviated 
  genie add -a getIsBack -m Terminator

Add a thunk to a specific model

  genie add --thunk countDux --model Dux
  
    ... or
  genie add -t countDux -m Dux
