It is designed to offer you everything you wished the native web components API provided. #### Tag definition ```html

Seconds Elapsed: { state.time }

``` [Open this example on Plunker](https://riot.js.org/examples/plunker/?app=timer) #### Mounting ```javascript // mount the timer with its initial props riot.mount('timer', { start: 0 }) ``` #### Nesting Custom components let you build complex views with HTML. ```html ``` HTML syntax is the de facto language on the web and it's designed for building user interfaces. The syntax is explicit, nesting is inherent to the language and attributes offer a clean way to provide options for custom tags. ### Performant and predictable - Absolutely the smallest possible amount of DOM updates and reflows. - Fast expressions bindings instead of virtual DOM memory performance issues and drawbacks. - One way data flow: updates and unmounts are propagated downwards from parent to children. - No "magic" or "smart" reactive properties or hooks - Expressions are pre-compiled and cached for high performance. - Lifecycle methods for more control. ### Close to standards - No proprietary event system. - Future proof thanks to the javascript module syntax. - The rendered DOM can be freely manipulated with other tools. - No extra HTML root elements, `data-` attributes or fancy custom attributes. - No new syntax to learn. - Plays well with any frontend framework. ### Use your dearest language and tools - Create components with CoffeeScript, Jade, LiveScript, Typescript, ES6 or [any pre-processor](https://riot.js.org/compiler/#pre-processors) you want. - Build with [@riotjs/cli](https://github.com/riot/cli), [webpack](https://github.com/riot/webpack-loader), [Rollup](https://github.com/riot/rollup-plugin-riot), [parcel](https://github.com/riot/parcel-plugin-riot), [Browserify](https://github.com/riot/riotify). - Test however you like; you can [load your riot tags directly in node](https://github.com/riot/ssr#render---to-render-only-markup) ### Powerful and modular ecosystem The Riot.js ecosystem is completely modular, it's designed to let you pick only the stuff you really need: - [@riotjs/cli](https://github.com/riot/cli) - CLI to locally compile your tags to javascript - [@riotjs/ssr](https://github.com/riot/ssr) - Super simple server side rendering - [@riotjs/hydrate](https://github.com/riot/hydrate) - Hydration strategy for your SPA - [@riotjs/route](https://github.com/riot/route) - Isomorphic router - [@riotjs/lazy](https://github.com/riot/lazy) - Lazy components loader - [@riotjs/hot-reload](https://github.com/riot/hot-reload) - Live reload plugin - [@riotjs/compiler](https://github.com/riot/compiler) - Advanced tags compiler - [@riotjs/parser](https://github.com/riot/parser) - HTML parser - [@riotjs/dom-bindings](https://github.com/riot/dom-bindings) - Expressions based template engine - [@riotjs/custom-elements](https://github.com/riot/custom-elements) - native custom elements implementation ### CDN hosting - [unpkg](https://unpkg.com/riot/riot.js) - [jsDelivr](https://www.jsdelivr.com/projects/riot) - [cdnjs](https://cdnjs.com/libraries/riot) ### How to contribute If you are reading this it's already a good sign and I am thankful for it! I try my best working as much as I can on riot but your help is always appreciated. If you want to contribute to riot helping the project maintenance please check first the list of [open issues](https://github.com/riot/riot/issues) to understand whether there is a task where you could help. Riot is mainly developed on UNIX systems so you will be able to run all the commands necessary to build and test the library using our [Makefile](Makefile). If you are on a Microsoft machine it could be harder to set up your development environment properly. Following the steps below you should be able to properly submit your patch to the project #### 1) Clone the repo and browse to the riot folder ```shell $ git clone git@github.com:riot/riot.git && cd riot ``` #### 2) Set up your git branch ```shell $ git checkout -b feature/my-awesome-patch ``` #### 3) Install the npm dependencies ```shell $ npm i ``` #### 4) Build and test riot using the Makefile ```shell # To build and test riot $ make riot # To build without testing $ make raw ``` #### 5) Pull request only against the `dev` branch making sure you have read [our pull request template](.github/PULL_REQUEST_TEMPLATE.md) #### 6) Be patient ### Credits Riot is actively maintained with :heart: by:
