Quick Start

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

// Start generating components/tests and save time \(• ◡ •)/

Getting Started

Running blueprint new <project name> will pull down the amazing Redux Starter Kit and initialize a new git repo. Running new will automatically set up a .blueprintrc 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 .blueprintrc in your project root. If you want to you can just create the .blueprintrc manually.

Final .blueprintrc 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.

Alternatively, if you use this CLI as a result of blueprint 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!

Default Settings

.blueprintrc

It's possible to put .blueprintrc files in other locations to better share configs. It looks for files in the following locations and deep merges the files it finds together. The defaultSettings will be overwritten by any following options while the --config=path/to/file option will override everything.

See the whole list and more ENV tricks at rc

1. defaultSettings
2. /etc/blueprint/config
3. /etc/blueprintrc
4. ~/.config/blueprint/config
5. ~/.config/blueprint
6. ~/.blueprint/config
7. ~/.blueprintrc
8. $BLUEPRINT_CONFIG
9. --config=path/to/file

Note - All files found at these locations will have their objects deep merged together. Later file override earlier ones

Commands

Generators

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

blueprint g dumb MyNewComponent --dry-run

// Output:

  info: installing blueprint...
  would create: /MyNewComponent.js
  would create: /MyNewComponent.test.js
  info: finished installing blueprint.

Roadmap

2.0

• rename to blueprint-cli
• replace commander with yargs for cli
• extend .blueprintrc settings.
• Allow .blueprintrc files to set search * path for blueprint directories
• Enable npm blueprint packages
• Enable better options support for blueprint generation
• Add Copy command to cli
• Add config command to cli
• Add blueprintrc and blueprint-package blueprints
• Update existing blueprints and move into own package, to be included by default

2.X

• Replace "new" command with alternate ways of project creation
• Enable blueprint partials
• Enable blueprints for assets: icons, images, css, fonts
• Enable ability to insert text into existing files
• Enable generators that can invoke other generators. Inspired by rails scaffold

Examples

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

// generates a dumb component
blueprint g dumb SimpleButton

// generates a smart component
blueprint g smart CommentContainer

// generate a redux-form with <form> tags in render statement
blueprint g form ContactForm

// generate a Redux 'duck' (reducer, constants, action creators)
blueprint g duck todos

Creating Blueprints

Blueprints are template generators with optional custom install logic.

blueprint 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. Blueprint 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 Blueprint CLI by typing: blueprint 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 blueprint g smart commentContainer then __name__ becomes commentContainer.

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

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

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

The __smart__ token is a custom token I added in the index.js it pulls from your .blueprintrc 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 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:

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: blueprint 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:

blueprint 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 'blueprint <commands>'
blueprint <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
