[](https://travis-ci.org/segmentio/khaos)
## Installation
$ npm install -g khaos
## Documentation
- [Creating Templates](/docs/templates.md)
- [Using the JavaScript API](/docs/api.md)
## Usage
The quickest way to start using Khaos is to create a new project from a template on GitHub. For example, using the [segmentio/khaos-node](https://github.com/segmentio/khaos-node) template...
$ khaos create segmentio/khaos-node my-new-project
...that will prompt you to fill in some placeholders...
name: ware
owner: segmentio
description: Easily create your own middleware layer.
...and voilà! Your new node.js project directory is created including a `package.json`, `Readme.md`, `Makefile`, and everything.
## Local Usage
Khaos can also use local templates at `~/.khaos` and there's a simple command for download GitHub repositories there. Here's the same example from above, but locally...
$ khaos install segmentio/khaos-node node
That installs Segment's node template and aliases it as `node`, so then from now on you can easily...
$ khaos create node my-new-project
...and fill out a few fields and your new project directory is created!
## How does it work?
Khaos templates are just plain old directories where any file or filename can have [**handlebars placeholders**](http://handlebarsjs.com/). When you create a new project, Khaos will scan the template for placeholders and prompt you to fill in a value for each one.
For example, say you have a `package.json` in your template...
```js
{
"name": "{{ name }}",
"repository": "{{ owner }}/{{ name }}",
"description": "{{ description }}",
"dependencies": {}
}
```
Khaos sees that and knows to prompt you for a `name`, `owner`, and `description` when generating the template, like so...
name: ware
owner: segmentio
description: Easily create your own middleware layer.
You can use handlebars conditional blocks too, so if you wanted to add an optional private flag...
```js
{
"name": "{{ name }}",
{{#private}}
"private": true,
{{/private}}
"repository": "{{ owner }}/{{ name }}",
"description": "{{ description }}",
"dependencies": {}
}
```
...and Khaos is smart enough to know that `private` is a boolean when it prompts you...
name: ware
private: (y/n) y
owner: segmentio
description: Easily create your own middleware layer.
What's cool about all this is it makes creating new templates incredibly easy. Just copy an existing project and replace the filled-in values with placeholders... now you can automate more things!
## Examples
To give you an idea for what's possible, check out a few examples:
- [A template for node projects.](https://github.com/segmentio/khaos-node) Pretty basic.
- [A template for react.js projects.](https://github.com/lapwinglabs/khaos-react)
- [A template for JSTransformer.](https://github.com/jstransformers/khaos-jstransformer)
- [A template for building Deku components.](https://github.com/stevenmiller888/khaos-deku-component)
- [A CLI that uses the Javascript API internally.](https://github.com/logo/cli/blob/master/bin/logo-create) Featuring custom plugins.
## Javascript API
In addition to using the simple CLI to create new projects, you can use Khaos straight from node.js in case you want to bake it into your own, more custom, scaffolding process. Checkout the [logo creation CLI](https://github.com/logo/cli/blob/master/bin/logo-create) for an example of this in action.
#### new Khaos(src, dest)
Create a new Khaos instance with a `src` template directory, and that will output to a `dest` directory.
#### #run(callback)
Run the prompting and scaffolding process and then `callback(err)`.
#### #use(plugin)
Use a custom `plugin` function. Khaos uses [Metalsmith](http://metalsmith.io) internally, so the plugin is just a regular Metalsmith plugin, and all of the prompted answers are available as global metadata.
## Thanks!
_Thank you so much to [Sorella](https://github.com/robotlolita) for letting us use the `khaos` name on npm!_
