UI5 Web Components

Travis CI Build Status npm Package Version REUSE status

What are UI5 Web Components?

  • A rich set of enterprise-grade reusable UI elements driven by a lightweight framework (~20K gzipped).
  • Suitable for building anything from static web sites to complex web applications.
  • Usable with any current or future web development framework (React, Angular, Vue, etc...).
  • Implement the SAP Fiori design and follow the SAP Fiori Design Guidelines for a consistent UX.
  • Created and maintained by SAP as part of the UI5 product family.

Why use web components?

  • Future-proof: being web standards, they are compatible with any version of any web development framework.
  • Encapsulated: the HTML/CSS in the shadow DOM are protected from interference by the web page and vice versa, making them stable in any environment and suitable not only for apps, but also for libraries and micro-frontends.
  • Elegant: being custom HTML elements, they hide implementation complexity behind a single HTML tag, making them easily usable with the standard DOM APIs.

Where can I see them in action?

1. What is UI5/OpenUI5?

OpenUI5 is an open source JS framework that lets you build enterprise-ready web applications, responsive to all devices, running on almost any browser of your choice. It's based on JavaScript, using jQuery as its foundation and follows web standards. It eases your development with a client-side HTML5 rendering library including a rich set of controls and supports data binding to different data models (JSON, XML and OData).

2. How do UI5 Web Components relate to OpenUI5?

UI5 Web Components…

  • …are not built on top of UI5, but rather lightweight and independent UI elements
  • …are not a successor of UI5, but rather a complementary offering
  • …bring the relevant UI5 qualities and SAP Fiori UX to the HTML level, usable with any web framework

UI5 Web Components are good for…

  • …web applications which already use a different web framework
  • static web sites built without web frameworks, to just add a few interactive UI elements

UI5 remains what it is: the best choice for…

  • …building complete enterprise-ready and responsive web applications

UI5 Web Components for React

UI5 Web Components for React is a wrapper implementation around UI5 Web Components which makes using them in React even more comfortable. The current version of React (react 16) has some shortcomings when it comes to handling Custom Elements, namely the binding of boolean attributes as well as adding event listeners to custom event names like selection-change. With the help of UI5 Web Components for React, you can use the UI5 Web Components in React as if they were native React components. In addition to that, this library is also offering TypeScript definitions for all components, some complex layout components built on top of UI5 Web Components as well as Charting Components.

How to use

  1. Install the NPM module(s) that ship the desired UI5 Web Component(s), for example if you need ui5-button:

    npm install @ui5/webcomponents
  2. Import the desired UI5 Web Component(s) to your app:

    import "@ui5/webcomponents/dist/Button.js"; // loads and defines ui5-button
  3. Use the UI5 Web Component(s) as you would use any HTML element:

    <ui5-button>Hello world!</ui5-button>

Note: For a full list of the UI5 Web Components (and the respective NPM modules that ship them), see Public module imports.

Is there a CDN I can use?

No, you are expected to import only the components (or other public APIs) that you are going to use and bundle them along with the rest of your application.

Browser support

UI5 Web Components are supported by all major modern browsers.

Project structure, development and build

This section might be of interest to you mainly if you need to run or build the project locally

Requirements

Note: The UI5 Web Components project is set up with the Yarn node package manager. This is because it offers functionality that the otherwise preferred npm package manager is currently lacking. Namely, the workspace setting which is currently used in the UI5 Web Components (mono-)repository. Note that npm might add this feature in the future.

Structure

UI5 Web Components contains several projects (NPM packages):

Project NPM Package Description
main UI5 Web Components Bread-and-butter components (buttons, inputs, popups, pickers, tables, etc...) that are generally found in web apps.
fiori UI5 Web Components Fiori More semantic components, specific to the Fiori UX (shell bar, side navigation, etc...) that are commonly found in SAP apps.
icons UI5 Web Components Icons A rich icons collection (SAP-icons), suitable for enterprise-grade apps
base UI5 Web Components Base The UI5 Web Components framework itself
theme-base UI5 Web Components Theme Base Theming assets (the default theme and additional accessibility themes)
localization UI5 Web Components Localization i18n functionality and CLDR assets
ie11 * UI5 Web Components IE11 Internet Explorer 11 polyfills and adapter code
playground N/A The playground application

* This package is deprecated as Internet Explorer 11 is no longer supported by UI5 Web Components. While the @ui5/webcomponents-ie11 package allows UI5 Web Components to run on old browsers (IE11, legacy Edge) today, future compatibility is not guaranteed and the project may stop working on old browsers even with the aid of this package. Use at your own risk.

How to run the project locally:

yarn # to install all dependencies
yarn start # to serve the project

You can then explore component test pages on:

You can start the Playground app with the following commands:

# install playground specific dependencies (one time only)
cd packages/playground
yarn install:dependencies

# start the playground from the project root
cd ../..
yarn start:playground

# open http://localhost:4000/

Note: If you wish to manually install dependencies & run the Playground you can check out our in depth tutorial

If you wish to run the tests locally on a Windows machine, you must also manually install Windows Build Tools 2015 and Python 2.7. See the instructions on how to do this.

Production Build

To build the UI5 Web Components project, run the following commands:

yarn # to install all dependencies
yarn build # to build the project

Afterwards, you can find the build output in the dist folder of the corresponding package folder. For example, to find the Button component (that belongs to the main package), look inside the packages/main/dist folder.

Limitations

None as of 1.0.0-rc.8
