react-responsive-ui

Responsive React UI components.

GitHub

On March 9th, 2020, GitHub, Inc. silently banned my account (and all my libraries) without any notice. I opened a support ticked but they didn't answer. Because of that, I had to move all my libraries to GitLab.

Install

npm install react-responsive-ui --save

React >= 16.3 is required.

Use

See the demo page. It has code examples for every component.

Demo

Online demo page.

To run the demo page locally:

npm run demo

And then go to http://localhost:8080

CSS

The CSS for this library resides in react-responsive-ui/style.css file and should be included on a page.

The stylesheet uses native CSS variables for easier styling. See variables.css for the list of all available variables. These variables have some sensible defaults which can be overridden:

:root {
  --rrui-unit               : 12px;
  --rrui-white-color        : white;
  --rrui-black-color        : black;
  --rrui-accent-color       : blue;
  --rrui-accent-color-light : cyan;
  --rrui-gray-color         : gray;
}

Native CSS variables work in all modern browsers, but older ones like Internet Explorer wont't support them. For compatibility with such older browsers one can use a CSS transformer like PostCSS with a "CSS custom properties" plugin like postcss-custom-properties.

When using Webpack

// React Responsive UI.
require('react-responsive-ui/style.css')
// Custom variable values.
require('./src/styles/react-responsive-ui-custom-variable-values.css')

And set up a postcss-loader with a CSS autoprefixer for supporting old web browsers.

When not using Webpack

Get the style.css file from this package, process it with a CSS autoprefixer for supporting old web browsers, and then include it on a page.

<head>
  <!-- React Responsive UI -->
  <link rel="stylesheet" href="/css/react-responsive-ui/style.css"/>
  <!-- Custom variable values -->
  <link rel="stylesheet" href="/css/react-responsive-ui-custom-variable-values.css"/>
</head>

Small Screen

The small-screen directory contains "small screen" ("mobile devices") styles for some of the components. For example, <Select/>s, <Autocomplete/>s, <ExpandableMenu/>s, <DatePicker/>s can open in fullscreen (not neccessarily a good idea though). <Modal/>s have less padding and <Snackbar/>s are full-width. These CSS files may also use native CSS variables.

Native CSS @import example:

/* Main style. */
@import url(~react-responsive-ui/style.css)
/* Less padding on `<Modal/>`s on mobile devices. */
@import url(~react-responsive-ui/small-screen/Modal.css) (max-width: 768px)
/* Full-width `<Snackbar/>`s on mobile devices. */
@import url(~react-responsive-ui/small-screen/Snackbar.css) (max-width: 768px)
/* Places a click-capturing overlay above `<DatePicker/>` input
   so that the `<input/>` is not focused on touch meaning that the
   keyboard won't slide in when the user taps the `<DatePicker/>` input. */
@import url(~react-responsive-ui/small-screen/DatePicker.InputOverlay.css) (max-width: 768px)

Validation

Each form component can be passed an error: String property. When passed, the component will be styled as "invalid" and the error will be displayed under the component.

Asterisk on required fields

To show asterisks (*) on required fields' labels:

When field value is empty:

/* (when the `value` is empty) */
/* Required input field labels will have asterisks. */
.rrui__input-label--required:after {
  content: '*';
  margin-left: 0.2em;
}

Regardless of whether the field value is empty or not:

/* (regardless of whether the `value` is empty or not) */
/* Required input field labels will have asterisks. */
.rrui__input-label--required-field:after {
  content: '*';
  margin-left: 0.2em;
}

Supported Browsers

IE 11, Edge, Firefox, Chrome, Safari (macOS, iOS) — have been tested.

Expandable components (Select, Autocomplete, ExpandableMenu) require Promise which is not present in IE 11 and requires a Promise polyfill to be included on a page.

Reducing footprint

Code

For a "tree-shaking" bundler (should work, but check it yourself just in case):

import { Modal, Button, TextInput } from 'react-responsive-ui'

For "ECMAScript modules" imports:

import Modal     from 'react-responsive-ui/modules/Modal'
import Button    from 'react-responsive-ui/modules/Button'
import TextInput from 'react-responsive-ui/modules/TextInput'

For CommonJS imports:

import Modal     from 'react-responsive-ui/commonjs/Modal'
import Button    from 'react-responsive-ui/commonjs/Button'
import TextInput from 'react-responsive-ui/commonjs/TextInput'

Styles

The CSS styles could also be imported selectively (theoretically): instead of importing the whole react-responsive-ui/style.css bundle, one could import just the necessary styles from the react-responsive-ui/styles/ folder. But there's a catch: some components' styles may also require some other styles to be loaded.

For example, the <Button/> component requires the following stylesheets to be loaded:

react-responsive-ui/styles/Button.css
react-responsive-ui/styles/ButtonReset.css
react-responsive-ui/styles/Input.css

And the <DatePicker/> component requires the following stylesheets to be loaded (didn't check):

react-responsive-ui/styles/DatePicker.css
react-responsive-ui/styles/ButtonReset.css
react-responsive-ui/styles/Input.css
react-responsive-ui/styles/TextInput.css
react-responsive-ui/styles/Expandable.css
react-responsive-ui/styles/Close.css

And don't forget about also including react-responsive-ui/variables.css when going with the selective styles import approach.

So it might be easier to just import the whole react-responsive-ui/style.css file.

Outline

By default all buttons and inputs have rrui__outline CSS class attached to them which hides the default browser outline for focused components.

.rrui__outline:not(.rrui__outline--default) {
  outline: none;
}

Instead of using the default browser outline which doesn't look pretty by any standards and which nobody uses (not "Google", not "Apple", not anyone else) the default react-responsive-ui styles define some custom :focus styling for most cases (though not for all of them). Still, these out-of-the-box :focus styles are quite subtle and if a developer is implementing a WAI-ARIA-compliant website then they should make sure that those :focus styles are more pronounced in each case.

Alternatively, those looking for a very-quick-and-dirty solution can use the same default browser outline, but prettier.

.rrui__outline:focus {
  box-shadow: 0 0 0 0.15rem #00aaff;
}

If a developer still prefers the default browser outline then they still can manually add rrui__outline--default CSS class to buttons and inputs to prevent outline: none CSS rule from being applied.

There's also an exported component called <KeyboardNavigationListener/> which listens to keydown events on document.body, and when it detects a Tab key being pressed it adds rrui__tabbing CSS class to document.body. Any further mouse or touch events reset the rrui__tabbing CSS class. This way rrui__outline can only be shown when the user is actually tabbing. It's still not considered a 100%-formally-correct solution because "screen readers" still emit all kinds of mouse events, or maybe some "screen readers" hypothetically don't emit a "keydown" event for the Tab key — who knows. It's more of an experimental feature. There're some other possible ideas like ./source/Interaction.js.

Inspecting Expandables

Expandables are implemented in such a way that they collapse when losing focus. This may present difficulties when trying to inspect expandable content via DevTools because switching to DevTools captures focus causing expandables to collapse. For such cases there's a global debug flag window.rruiCollapseOnFocusOut which can be set to false to prevent expandables from collapsing when losing focus. This flag affects: <Select/>, <Autocomplete/>, <ExpandableMenu/>, <SlideOutMenu/>, <DatePicker/>, <Snackbar/>, <Tooltip/>.

Known Issues

An overflown <Modal/> scroll is janky on iOS because it tries to scroll <body/> instead of the <Modal/> contents. That's how it is on iOS.

Contributing

After cloning this repo, ensure dependencies are installed by running:

npm install

This module is written in ES6 and uses Babel for ES5 transpilation. Widely consumable JavaScript can be produced by running:

npm run build

Once npm run build has run, you may import or require() directly from node.

After developing, the full test suite can be evaluated by running:

npm test

When you're ready to test your new functionality on a real project, you can run

npm pack

It will build, test and then create a .tgz archive which you can then install in your project folder

npm install [module name with version].tar.gz
