An extraordinary JavaScript framework for creating client-side web applications, UI components libraries, or single web components with unique mixed declarative and functional architecture

Hybrids provides a complete set of features for building modern web applications:

• Component Model based on plain objects and pure functions
• Global State Management with external storages, offline caching, relations, and more
• App-like Routing based on the graph structure of views
• Layout Engine making UI layouts development much faster
• Localization with automatic translation of the templates content
• Hot Module Replacement support without any additional configuration

The project documentation is available at thehybrids.js.org site.

It's based on plain objects and pure functions¹, still using theWeb Components API under the hood:

import{html,define}from"hybrids";functionincreaseCount(host){host.count+=1;}exportdefaultdefine({tag:"simple-counter",count:0,render:({ count})=>html`<buttononclick="${increaseCount}">      Count:${count}</button>  `,});

<simple-countercount="42"></simple-counter>

You can read more in theComponent Model section.

A global state management uses declarative model definitions with support for async external storages, relations, offline caching, and many more:

import{define,store,html}from"hybrids";constUser={id:true,firstName:"",lastName:"",[store.connect] :{get:id=>fetch(`/users/${id}`).then(...),},};define({tag:"user-details",user:store(User),render:({ user})=>html`<div>${store.pending(user)&&`Loading...`}${store.error(user)&&`Something went wrong...`}${store.ready(user)&&html`<p>${user.firstName}${user.lastName}</p>      `}</div>  `,});

<user-detailsuser="2"></user-details>

You can read more in theStore section.

Rather than just matching URLs with the corresponding components, the router depends on a tree-like structure of views, which have their own routing configuration. It makes the URLs optional, have out-the-box support for dialogs, protected views, and many more.

import{define,html,router}from"hybrids";importDetailsfrom"./details.js";constHome=define({[router.connect]:{stack:[Details, ...]},tag:"app-home",render:()=>html`<templatelayout="column"><h1>Home</h1><navlayout="row gap"><ahref="${router.url(Details)}">Details</a></nav>      ...</template>  `,});exportdefine({tag:"app-router",stack:router(Home),render:({ stack})=>html`<templatelayout="column">${stack}</template>  `,});

<app-router></app-router>

You can read more in theRouter section.

Create CSS layouts in-place in templates, even without using Shadow DOM, but still keeping the encapsulation of the component's styles:

define({tag:"app-home-view",render:()=>html`<templatelayout="column center gap:2"><divlayout="grow grid:1|max"><h1>Home</h1>        ...</div><footerlayout@768px="hidden">...</footer></template>  `});

You can read more in theLayout Engine section of the documentation.

The library supports automatic translation of the component's content, which makes translation seamless and easy to integrate. Additionally, it provides a way to add dynamic messages with plural forms, HTML content, or use messages outside of the template context. Also, it comes with handy CLI tool to extract messages from the source code!

import{define,html,localize}from"hybrids";exportdefaultdefine({tag:"my-element",name:"",render:({ name})=>html`<div>Hello${name}!</div>  `,});localize("pl",{"Hello ${0}!":{message:"Witaj ${0}!",},});

You can read more in theLocalization section of the documentation.
