A suite of pre-built Dojo 2 widgets, ready to use in your web application. These widgets are built using Dojo 2's widget authoring system (@dojo/widget-core).
To use @dojo/widgets in your project, you will need to install the package:
install @dojo/widgets
This package contains all of the widgets in this repo.
All of the widgets are on the same release schedule, that is to say, that we release all widgets at the same time. Minor releases may include new widgets and/or features, whereas patch releases may contain fixes to more than 1 widget.
To use a widget in your application, you will need to import each widget individually:
rt Button from '@dojo/widgets/button/Button';
Each widget module has a default export of the widget itself, as well as named exports for things such as properties specific to the widget:
rt Button, { ButtonProperties } from '@dojo/widgets/button/Button';
Because each widget is a separate module, when you create a release build of your application, you will only include the widgets that you have explicitly imported.
This allows our dojo cli build tooling to make sure that the production build of your application only includes the widgets you use and is as small as possible.
All widgets are supported in all evergreen browsers (Chrome, Edge, Firefox, IE11+, and Safari) as well as popular mobile browsers (Mobile Safari, Chrome on Android).
All widgets are designed to be accessible. If custom ARIA semantics are required, widgets have an aria property that may be passed an object with custom aria-* attributes.
All widgets are fully themeable. Example themes are available in the @dojo/themes repository.
All widgets support internationalization (i18n)
Live examples of current widgets are available in the widget showcase.
You can register event handlers that get called when the corresponding events occur by passing the handlers into a widget's properties.
The naming convention for event handlers is as follows:
if the parent of the widget has the power to decide if an event is successful, i.e. can cancel the event, then the child widget will call an event handler in the following format:
onRequest[X], e.g. for a close event, the event handler called by the child widget must be called onRequestClose
Here the child widget is requesting that the close event take place.
for events that will occur regardless of child/parent interaction, then the Request naming convention is dropped:
on[X], e.g. for a dismiss event, the event handler called by the child widget must be called onDismiss
We use font awesome for icons. Where a theme requires specific icons that are not part of the Font Awesome set, then those themes will ship their own icons.
There is an icon widget that aids in creating in proper semantics and provides type-checking for the type of icon.
px vs. em - we specify font sizes in px.
When creating a widget, spacing (margin, padding) should be specified using px unless the design calls for proportional spacing, in which case em can be used.
Widgets adhere to a basic convention for using specific ranges of z-index values based on function and visual context. This convention is followed in both individual widget CSS and in the Dojo theme styles. These values can be overridden in a custom theme if necessary since no z-index values are set in fixed styles.
The range definitions are as follows:
There are many ways in which you can customize the behavior and appearance of Dojo 2 widgets.
See the widget-core README for examples of how to customize the theme or a specific CSS class of a widget.
Or can you write your own widget that extends an official widget.
Because all Dojo 2 widgets are Classes, you can simply extend the Class to add or change its behavior.
rt class MyWidget extends Button {
Dojo 2 widgets provide standard extension points to allow you to customize their behavior. For more details, please refer to the widget authoring system.
Individual widgets also provide certain types of extension points where applicable:
render*: Large render functions are split up into multiple smaller pieces that can be more easily overridden to create custom vdom.getModifierClasses: Modify the array of conditionally applied classes like css.selected or css.disabled.
Not all widgets include these extension points, and some have additional overridable methods.We appreciate your interest! Please see the Dojo 2 Meta Repository for the Contributing Guidelines and Style Guide.
To start working with this package, clone the repository and run npm install.
In order to build the project run grunt dev or grunt dist.
Test cases MUST be written using Intern using the Object test interface and Assert assertion interface.
90% branch coverage MUST be provided for all code submitted to this repository, as reported by istanbul?s combined coverage results for all supported platforms.
To test locally in node run:
grunt test
To test against browsers with a local selenium server run:
grunt test:local
To test against BrowserStack or Sauce Labs run:
grunt test:browserstack
or
grunt test:saucelabs
Each Dojo 2 widget includes functioning example code so you can view the widget. To view individual widget example:
grunt dev in your terminal_build/common/example/index.html in your web browserRunning grunt dev each time you wish to view a small change takes more time than simply running this command in your terminal:
-w
With that command, TypeScript watches for changes and recompiles when necessary.
