# Install

Choose an Interface:

- [Command-Line](#install-cli)
- [JavaScript (Node.js)](#install-js)

<a name="install-cli"></a>

## Command-Line

Use [npm](https://npmjs.com) or [Homebrew](https://brew.sh) to install the Command-Line interface of Autocode:

```sh
npm install autocode-cli -g # most popular
brew install autocode # mac only
```

<a name="install-js"></a>

## JavaScript (Node.js)

Use [npm](https://npmjs.com) to install the JavaScript interface of Autocode:

```sh
npm install autocode-js
```

<a name="hello-world"></a>

# Hello World

Choose the `Hello World` tutorial for your Autocode installation:

- [Input](#example-input)
  - [Command-Line](#hello-world-cli)
  - [JavaScript (Node.js)](#hello-world-js)
- [Output](#output)
  - [README.md](#readme)
  - [LICENSE](#license)

## Input

<a name="#hello-world-cli"></a>

### Command-Line

If you've installed the Command-Line interface of Autocode, create a file called `.autocode/config.yml` and add these contents:

```yaml
name: My App
description: This is my app.
path: ./output/myapp
imports:
  crystal/license: ~0.3.1
  crystal/readme: ~0.5.1
outputs:
  - generator: license.MITGenerator
    spec:
      copyright: 2015 Crystal
  - generator: readme.ReadmeGenerator
    spec:
      name: $name
      description: $description
```

Then use Autocode to build your project:

```sh
autocode build
```

View the output [here](#output).

<a name="#hello-world-js"></a>

### JavaScript (Node.js)

If you've installed the JavaScript interface of Autocode, create a file called `helloworld.js` and add these contents:

```js
var Autocode = require('autocode-js');
var project = new Autocode({
  name: 'My App',
  description: 'This is my app.',
  path: './output/myapp',
  imports: {
    'crystal/license': '~0.3.1',
    'crystal/readme': '~0.5.1'
  },
  outputs: [{
    // generate a LICENSE file
    generator: 'license.MITGenerator',
    spec: {
      copyright: '2015 Crystal'
    }
  },{
    // generate a README.md file
    generator: 'readme.ReadmeGenerator',
    spec: {
      name: '$name',
      description: '$description'
    }
  }]
});
```

Now run your `helloworld.js` script:

```sh
node helloworld.js
```

View the output [here](#output).

<a name="output"></a>

## Output

Whether you've chosen the Command-Line interface or JavaScript interface, the output will be the same:

- [README.md](#readme)
- [LICENSE](#license)

<a name="#readme"></a>

### README.md

```md
# My API

this is my API
```

<a name="#license"></a>

# Top 10 Features

(1) Crystal unifies all technologies with a standardized input written in YAML, JSON, CSON and/or XML.

(2) Crystal generates code for:

  - Any application: APIs, Apps, Websites, Frontends, Backends + more
  - Any language: JavaScript, PHP, Ruby, Python, Swift, Java + more
  - Any framework: Express, Hapi, Laravel, Yii, Rails, Sinatra, Django + more
  - Any platform: Twitter, Facebook, Mailchimp, Pinterest, Google + more
  - Any runtime/server: Node.js, Apache, Nginx, HAPROXY + more
  - Any CMS: Wordpress, Drupal, Joomla, Plone, Keystone + more
  - Any datastore: MySQL, PostgreSQL, Redis, MongoDB, DynamoDB + more
  - Any file: README, LICENSE, AUTHORS, HOSTS + more
  - ...and any other software!!
  
(3) Crystal is made up of 8 elements that make code generation more flexible and powerful than ever before:

  - [Specifications](https://crystal.readme.io/v0.8/docs/specifications)
  - [Schematics](https://crystal.readme.io/v0.8/docs/schematics)
  - [Generators](https://crystal.readme.io/v0.8/docs/generators)
  - [Engines](https://crystal.readme.io/v0.8/docs/engines)
  - [Helpers](https://crystal.readme.io/v0.8/docs/helpers)
  - [Processors](https://crystal.readme.io/v0.8/docs/processors)
  - [Transformers](https://crystal.readme.io/v0.8/docs/transformers)
  - [Injectors](https://crystal.readme.io/v0.8/docs/injectors)
  
(4) Crystal is meant to be used on an ongoing basis - beyond project creation and scaffolding.

(5) Crystal has its own registry (the [Crystal Hub](https://hub.crystal.sh)) and package manager built-in which makes it easy to search, install and update modules.

(6) All of Crystal's elements can be modularized and published to the Crystal Hub for you or others to use.

(7) You can use multiple modules together such as a:

  - README generator for documentation
  - MIT generator for licensing
  - Composer generator for frontend dependencies
  - Bower generator for backend dependencies
  - Laravel generator for business logic
  - Ember generator for UI

(8) You can add/remove modules to/from a project at anytime.

(9) To prevent vendor lock-in and becoming dependent of Crystal, it's kept in its own directory: `.autocode/`. If you wish to no longer use Crystal, simply delete this directory and continue using the generated code (and making changes) without Crystal.

(10) Crystal makes language integration and/or migration easier.
