# Hibiki HTML



Hibiki HTML is a new web framework for creating modern front-end applications,

without scaffolding or setting up a JavaScript stack,

that can be fully [scripted and controlled by backend code](#hibiki-actions).



Hibiki HTML is compatible with any backend language or framework, any

CSS framework, and any existing backend template language.



For an interactive walkthrough please check out the 

[Hibiki HTML Interactive Tutorial](https://playground.hibikihtml.com/tutorial/).

Hibiki was featured in [Console](https://console.substack.com/p/console-99), a great newsletter for learning about open-source projects!



## Getting Started



Getting started is easy.  There is no JavaScript stack to set up, no boilerplate/scaffolding, and

no build tools to download and run.

Just add one script tag to the top of your page or template:



```



```



Wrap any portion of your content with a <template hibiki> tag and you have your first

Hibiki HTML app.  All plain HTML content is rendered as is, and because Hibiki HTML uses the browser's HTML parser,

it follows the same rules as standard browser HTML.



Note that all these code examples can be viewed and edited in the 

[Hibiki HTML Playground](https://playground.hibikihtml.com).



```

```

As of v0.3.3, you may also wrap your Hibiki code in a <script type="text/hibiki-html"> tag and optionally reference your Hibiki src code and initial data as remote URLs:



```



 ... Hibiki HTML code here 



 ... Hibiki HTML code here ... 



```



## Data / Rendering Dynamic Content



Hibiki HTML applications have a built-in frontend data model.  You can initialize it with

any JSON object using the `````` tag.  To render text use

the `````` tag or inline ```{{ ... }}``` syntax.  Attributes and style properties

are evaluated dynamically if they start with a ```*```.



```



  

    {"color": "blue", "name": "Mike"}

  

  


    {{ $.name }}'s favorite color is 

    {{ $.color }}

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-data-1)



Hibiki HTML supports a full expression language, including all of the standard conditional and arithmetic

operators.  Additional classes can be turned on/off using the shorthand

attribute syntax ```class.[class-name]="true/false expression"```.

```



  

    {"numlights": 4, "selected": true, "index": 5, "isprimary": true}

  

  


    Bold Text (if selected)

  


  
Index: 


  


    There are {{$.numlights}} light{{$.numlights > 1 ? 's' : ''}}

  


  


    Primary Button

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-data-2)



You can conditionally include elements using the ```if``` attribute.  Looping

is handled by the ```foreach``` attribute.  You can loop over arrays or

objects.  The foreach attribute uses a special syntax of ```@item in $.array```,

where every iteration ```@item``` will be assigned to an element of the array or object.

If you provide a second variable it will capture the array index or element key:

```(@item, @key) in $.object``` or ```(@item, @idx) in $.array```.



```



  

    {"fruits": [{"name": "apple", "emoji": "🍎"},

                {"name": "banana", "emoji": "🍌"}, 

                {"name": "blueberry", "emoji": "🫐"}], 

     "selected": "banana"}

  

  


    
    

          
  • 

            {{ @fruit.name }} {{ @fruit.emoji }}

            (selected)

          
    • 

        


  



```

## Handlers



To update data (and dynamically change content), Hibiki HTML supports *handlers*.  Basic handlers respond to

events like *click*, *mount*, *submit*, *change*, etc.



```



  {"color": "blue"}

  


    The color is {{$.color}}

  


  Change Color



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-handlers-1)



You can make remote AJAX calls for JSON data using a remote handler.  In this example

the call to https://testapi.hibikihtml.com/api/get-color-1 will return the JSON

response ```{"color": "purple"}```.  We assign it to a *context variable* ```@resp``` and

then assign ```$.color = @resp.color```.



```



  {"color": "blue"}

  


    The color is {{$.color}}

  


  Change Color

  

    GET /api/get-color-1

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-handlers-2)



You can make GET, POST, PUT, PATCH, or DELETE requests by changing the verb in front of the URL.  You can

pass query arguments (or JSON data bodies) by passing arguments to your handler by using ```(arg1=val1, arg2=val2...)``` (complex arguments will be JSON encoded), and you can define local handlers using the ```define-handler``` tag for convenience and reuse.



```



  {"color": "blue"}

  

    @resp = GET https://testapi.hibikihtml.com/api/get-color-1(name="Michelle");

    $.color = @resp.color;

  

  


    The color is {{$.color}}

  


  Change Color

  

    Get Michelle's Color

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-handlers-3)



Connecting to an existing API?  Don't worry, Hibiki HTML handlers support advanced options

like CORS, CSRF, parameter encodings, BLOB results, and multipart file uploads.



## Hibiki Actions



The magic of Hibiki HTML is that every handler is really just a series of actions.  *Hibiki Actions*

are primitives like *setdata*, *if*, *callhandler*, *fireevent*, *invalidate*, *html*, etc.  Every action

that can you can write in a handler, also has a JSON representation.



This means we can write a *backend* handler that returns a JSON response that scripts

and updates the frontend!  Here's an example JSON response that is equivalent to running

```$.color = 'DeepSkyBlue'``` on the frontend:



```

{"hibikiactions": [

    {"actiontype": "setdata", "setpath": "$.color", "data": "DeepSkyBlue"}

]}

```



I've set up https://testapi.hibikihtml.com/api/set-color-action to return just that.  Now

if we have our click handler call that URL, we'll see the color change automatically.



```



  {"color": "red"}

  


    The color is {{$.color}}

  


  Change Color

  

    Backend Set Color Action

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-actions-1)



Backend handlers are *very* powerful.  You can set return values, return data and BLOBs (like images) in

one request, mix frontend and backend data with expressions, conditionally execute actions, and more.

You can also use backend handlers to create multi-page Hibiki HTML applications by returning a

new HTML template to be rendered.



## Components and Libraries



Hibiki HTML makes it easy to use, share, and bundle components for easy reuse.  The ecosystem is just getting 

started, but you can write native Hibiki HTML components, link to 3rd party JavaScript (D3, CodeMirror, etc.),

and import ReactJS components.



```



  

    


      The color is {{$args.color}}

    


  

  

  

  

  



```

(Playground Link - https://playground.hibikihtml.com/?codeid=readme-comps-1)



## Bulma UI Component Library



I've released a Hibiki wrappers for the excellent [Bulma UI Library](https://bulma.io).

It can easily be included in any Hibiki template by adding:

```



```



Documentation for the Hibiki+Bulma library can be found at https://libs.hibikihtml.com/test-bulma.html .

It includes many interactive controls including tabs, menus, cards, dropdowns, form controls, and

a data table that supports sorting and pagination.

## Credits



Hibiki HTML is an open source version of the frontend language originally built and designed for

the [Dashborg](https://dashborg.net) internal tools framework.  The Hibiki HTML core is built in [TypeScript](https://www.typescriptlang.org/), using

[React](https://reactjs.org/), [MobX](https://mobx.js.org/), and [Nearley](https://nearley.js.org/). 

The Hibiki HTML playground is built in Hibiki HTML, also using 

[CodeMirror](https://codemirror.net/) and [Bulma](https://bulma.io).



## Support and Help



Hibiki HTML is under active development.  Please contact me by email [mike (at) hibikihtml.com] 

or on Discord if you have a question, to report a bug, need help, or would like to contribute.



I'm excited to see Hibiki HTML working in the real world.  If you have an application that you're
