Quick Start

npm i redux-cli -g       // install redux-cli globally
redux new <project name> // create a new redux project
redux new <project name> -S // OR use ssh to pull project down (if ssh setup with github)
redux init                  // OR configure a current project to use the CLI

Getting Started

Running redux new <project name> will pull down the amazing Redux Starter Kit and initialize a new git repo. Running new will automatically set up a .reduxrc to work with this specific starter kit. If you want to integrate the CLI in an existing project or store your components in different paths please see config existing project

Config Existing Project

There is an init subcommand for you to specify all paths to where components live in your project. The init command just creates a .reduxrc in your project root. If you want to you can just create the .reduxrc manually.
Final .reduxrc might look like this:

{
  "sourceBase":"src",
  "testBase":"tests",
  "smartPath":"containers",
  "dumbPath":"components",
  "fileCasing": "default"
}
```  

**Note on configuration**:  
This project tries to walk on a fine line between convention and configuration.
Since the majority of React applications will separate their smart/dumb
components if you pass in those paths you'll get those generators for free.
However, some of the other generators might not write files to the exact paths
that you use for your project.  It's easy to override the CLI generators with
your own so that the generators will write files to the correct location.  
[See: creating custom blueprints](#creating-blueprints).

Alternatively, if you use this CLI as a result of `redux new <project name>` the
starter kit will come pre-configured with a bunch of blueprints (generators)
that work out of the gate.  Currently, I'm working on a PR for the
`react-redux-starter-kit` with a bunch of blueprints.  More starter kits and
blueprints to come!

### Initial Configuration
|Key Name|Required|Description|
|---|---|---|
|**sourceBase**|✓|where you keep your pre-compiled source (relative from root of project)|
|**testBase**|✓|where you keep your tests (relative from root of project)|
|**smartPath**|✓|where you keep your smart (container) components (relative of sourceBase)|
|**dumbPath**|✓|where you keep your dumb (pure) components (relative of sourceBase)|
|**fileCasing**|✓|how do you want generated files to be named (pascal/camel/snake/dashes/default)|

### Commands

|Command|Description|Alias|
|---|---|---|
|`redux new <project name>`|creates a new redux project||
|`redux init`|configure an existing redux app to use the CLI||
|`redux generate <generator name> `|generates files and tests for you automatically|`redux g`|
|`redux help g`|show all generators you have available||


### Generators

|Name|Description|Options|
|---|---|---|
|`redux g dumb <comp name>`|generates a dumb component and test file||
|`redux g smart <smart name>`|generates a smart connected component and test file||
|`redux g form <form name>`|generates a form component (assumes redux-form)||
|`redux g duck <duck name>`|generates a redux duck and test file||

You can also see what files would get created with the `--dry-run` option like
so:

redux g dumb MyNewComponent --dry-run
// Output:
info: installing blueprint... would create: /MyNewComponent.js would create: /MyNewComponent.test.js info: finished installing blueprint.

### Examples
Below are some examples of using the generator to speed up development:

// generates a dumb component redux g dumb SimpleButton
// generates a smart component redux g smart CommentContainer
// generate a redux-form with tags in render statement redux g form ContactForm
// generate a Redux 'duck' (reducer, constants, action creators) redux g duck todos

### Creating Blueprints
Blueprints are template generators with optional custom install logic.  

`redux generate` comes with a default set of blueprints.  Every project has
their own configuration & needs, therefore blueprints have been made easy to override
and extend.

**Preliminary steps**:

1.  Create a `blueprints` folder in your root directory.  Redux CLI will search
for blueprints there _first_ before generating blueprints that come by default.  
2.  Create a sub directory inside `blueprints` for the new blueprint OR use the
blueprint generator (super meta I know) that comes with Redux CLI by typing:
`redux g blueprint <new blueprint name>`.  
3.  If you created the directory yourself than make sure to create a `index.js`
file that exports your blueprint and a `files` folder with what you want
generated.  

**Customizing the blueprint**:

Blueprints follow a simple structure. Let's take the built-in
`smart` blueprint as an example:

blueprints/smart ├── files │   ├── root │   │   └── smart │   │   └── name.js │   └── test │   └── smart │   └── name.test.js └── index.js

#### File Tokens

`files` contains templates for all the files to be generated into your project.

The `__name__` token is subtituted with the 
entity name at install time.  Entity names can be configued in
either PascalCase, snake_case, camelCase, or dashes-case so teams can customize their file
names accordingly.  By default, the `__name__` will return whatever is entered
in the generate CLI command.

For example, when the user
invokes `redux g smart commentContainer` then `__name__` becomes
`commentContainer`.

The `__root__` token is subsituted with the absolute path to your source.
Whatever path is in your `.reduxrc`'s `sourceBase` will be used here.

The `__test__` token is substitued with the absolute path to your tests.
Whatever path is in your `.reduxrc`'s `testBase` will be used here.

The `__path__` token is substituted with the blueprint
name at install time. For example, when the user invokes
`redux generate smart foo` then `__path__` becomes
`smart`.  

The `__smart__` token is a custom token I added in the `index.js` it pulls from
your `.reduxrc` configuration file to use whatever you have set as your
`smartPath`.

#### Template Variables (AKA Locals)

Variables can be inserted into templates with
`<%= someVariableName %>`.  The blueprints use [EJS](http://www.embeddedjs.com/)
for their template rendering so feel free to use any functionality that EJS
supports.

For example, the built-in `dumb` blueprint
`files/__root__/__name__.js` looks like this:

```js
import React, { Component, PropTypes } from 'react';

const propTypes = {
};

class <%= pascalEntityName %> extends Component {
  render() {
    return (
    )
  }
}

<%= pascalEntityName %>.propTypes = propTypes;
export default <%= pascalEntityName %>;

<%= pascalEntityName %> is replaced with the real value at install time. If we were to type: redux g dumb simple-button all instances of <%= pascalEntityName %> would be converted to: SimpleButton.
The following template variables are provided by default:

• pascalEntityName
• camelEntityName
• snakeEntityName
• dashesEntityName

The mechanism for providing custom template variables is described below.

Index.js

Custom installation (and soon uninstallation) behaviour can be added by overriding the hooks documented below. index.js should export a plain object, which will extend the prototype of the Blueprint class.

module.exports = {
  locals: function(options) {
    // Return custom template variables here.
    return {};
  },

  fileMapTokens: function(options) {
    // Return custom tokens to be replaced in your files
    return {
      __token__: function(options){
        // logic to determine value goes here
        return 'value';
      }
    }
  },

  filesPath: function() {
    // if you want to store generated files in a folder named
    // something other than 'files' you can override this
    return path.join(this.path, 'files');
  },

  // before and after install hooks
  beforeInstall: function(options) {},
  afterInstall: function(options) {},
};

Blueprint Hooks

As shown above, the following hooks are available to blueprint authors:

• locals
• fileMapTokens
• filesPath
• beforeInstall
• afterInstall

locals

Use locals to add custom tempate variables. The method receives one argument: options. Options is an object containing general and entity-specific options.
When the following is called on the command line:

redux g dumb foo --html=button --debug

The object passed to locals looks like this:

{
  entity: {
    name: 'foo',
    options: {
      _: ['dumb', 'foo'],
      html: 'button'
    },
    rawArgs: [
      ... array of rawArgs passed to cli ...
    ]
  },
  debug: true
}

This hook must return an object. It will be merged with the aforementioned default locals.

fileMapTokens

Use fileMapTokens to add custom fileMap tokens for use in the mapFile method. The hook must return an object in the following pattern:

{
  __token__: function(options){
    // logic to determine value goes here
    return 'value';
  }
}

It will be merged with the default fileMapTokens, and can be used to override any of the default tokens.
Tokens are used in the files folder (see files), and get replaced with values when the mapFile method is called.

filesPath

Use filesPath to define where the blueprint files to install are located. This can be used to customize which set of files to install based on options or environmental variables. It defaults to the files directory within the blueprint's folder.

beforeInstall & afterInstall

Called before any of the template files are processed and receives the the options and locals hashes as parameters. Typically used for validating any additional command line options or for any asynchronous setup that is needed.

Contributing

This CLI is very much in the beginning phases and I would love to have people help me to make it more robust. Currently, it's pretty opinonated to use the tooling/templates I prefer in my projects but I'm open to PR's to make it more universal and support other platforms (I'm on Mac).
This repo uses Zenhub for managing issues. If you want to see what's currently being worked on or in the pipeline make sure to install the Zenhub Chrome Extension and check out this projects 'Boards'.

Development Setup/Contributing

Use npm link is to install the CLI locally when testing it and adding features.

nvm use 5.1.0    // install node V5.1 if not present (nvm install 5.1.0)
npm install
npm i eslint babel-eslint -g  // make sure you have eslint installed globally
npm start        // to compile src into lib
npm test         // make sure all tests are passing

// to test the cli in the local directory you can:
npm link         // will install the npm package locally so you can run 'redux <commands>'
redux <run commands here>

Package Utility Scripts:

npm start        // will watch files in src and compile using babel
npm test         // runs test suite with linting.  Throws when lint failing
npm run lint     // lints all files in src and test
