A Delightful and Performant Spring Bottom Sheet with React

Logo with the text Accessible, Delightful and Performant

react-spring-bottom-sheet is built on top of react-spring and react-use-gesture. It busts the myth that accessibility and supporting keyboard navigation and screen readers are allegedly at odds with delightful, beautiful and highly animated UIs. Every animation and transition is implemented using CSS custom properties instead of manipulating them directly, allowing complete control over the experience from CSS alone.

Install

npm i react-spring-bottom-sheet

Demos

Basic

View demo code

MVP example, showing what you get by implementing open, onDismiss and a single snap point always set to minHeight.

Snap points & overflow

View demo code

A more elaborate example that showcases how snap points work. It also shows how it behaves if you want it to be open by default, and not closable. Notice how it responds if you resize the window, or scroll to the bottom and starts adjusting the height of the sheet without scrolling back up first.

Sticky header & footer

View demo code

If you provide either a header or footer prop you’ll enable the special behavior seen in this example. And they’re not just sticky positioned, both areas support touch gestures.

Non-blocking overlay mode

View demo code

In most cases you use a bottom sheet the same way you do with a dialog: you want it to overlay the page and block out distractions. But there are times when you want a bottom sheet but without it taking all the attention and overlaying the entire page. Providing blocking={false} helps this use case. By doing so you disable a couple of behaviors that are there for accessibility (focus-locking and more) that prevents a screen reader or a keyboard user from accidentally leaving the bottom sheet.

Get started

API

props

All props you provide, like className, style props or whatever else are spread onto the underlying <animated.div> instance, that you can style in your custom CSS using this selector: [data-rsbs-root]. Just note that the component is mounted in a @reach/portal at the bottom of <body>, and not in the DOM hierarchy you render it in.

open

Type: boolean

The only required prop. And it’s controlled, so if you don’t set this to false then it’s not possible to close the bottom sheet.

onDismiss

Type: () => void

Called when the user do something that signal they want to dismiss the sheet:

  • hit the esc key.
  • tap on the backdrop.
  • swipes the sheet to the bottom of the viewport.

snapPoints

Type: (state) => number | number[]

This function should be pure as it’s called often. You can choose to provide a single value or an array of values to customize the behavior. The state contains these values:

  • headerHeight – the current measured height of the header.
  • footerHeight – if a footer prop is provided then this is its height.
  • height – the current height of the sheet.
  • minHeight – the minimum height needed to avoid a scrollbar. If there’s not enough height available to avoid it then this will be the same as maxHeight.
  • maxHeight – the maximum available height on the page, usually matches window.innerHeight/100vh.

defaultSnap

Type: number | (state) => number

Provide either a number, or a callback returning a number for the default position of the sheet when it opens. state use the same arguments as snapPoints, plus two more values: snapPoints and lastSnap.

header

Type: ReactNode

Supports the same value type as the children prop.

footer

Type: ReactNode

Supports the same value type as the children prop.

initialFocusRef

Type: React.Ref

A react ref to the element you want to get keyboard focus when opening. If not provided it’s automatically selecting the first interactive element it finds.

blocking

Type: boolean

Enabled by default. Enables focus trapping of keyboard navigation, so you can’t accidentally tab out of the bottom sheet and into the background. Also sets aria-hidden on the rest of the page to prevent Screen Readers from escaping as well.

ref

Methods available when setting a ref on the sheet:

export default function Example() {
  const sheetRef = React.useRef()
  return <BottomSheet open ref={sheetRef} />
}

snapTo

Type: (numberOrCallback: number | (state => number)) => void

Same signature as the defaultSnap prop, calling it will animate the sheet to the new snap point you return. You can either call it with a number, which is the height in px (it’ll select the closest snap point that matches your value): ref.current.snapTo(200). Or ref.current.snapTo(({headerHeight, footerHeight, height, minHeight, maxHeight, snapPoints, lastSnap}) => Math.max(...snapPoints)).

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

  • React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
  • React.js and React Native have similar syntax and workflows, but their implementation is quite different.
  • React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
  • React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

* React.js Developer Salary by Country

  • United States- $120,000
  • Canada - $110,000
  • United Kingdom - $71,820
  • The Netherlands $49,095
  • Spain - $35,423.00
  • France - $44,284
  • Ukraine - $28,990
  • India - $9,843
  • Sweden - $55,173
  • Singapore - $43,801

In context of software developer wage rates, the United States continues to lead. In high-tech cities like San Francisco and New York, average React developer salaries will hit $98K and $114per year, overall.

However, the need for React.js and React Native developer is outpacing local labour markets. As a result, many businesses have difficulty locating and recruiting them locally.

It’s no surprise that for US and European companies looking for professional and budget engineers, offshore regions like India are becoming especially interesting. This area has a large number of app development companies, a good rate with quality, and a good pool of React.js front-end developers.

As per Linkedin, the country’s IT industry employs over a million React specialists. Furthermore, for the same or less money than hiring a React.js programmer locally, you may recruit someone with much expertise and a broader technical stack.

How to Hire React.js Developers?

  • Conduct thorough candidate research, including portfolios and areas of expertise.
  • Before you sit down with your interviewing panel, do some homework.
  • Examine the final outcome and hire the ideal candidate.

Why is React.js Popular?

React is a very strong framework. React.js makes use of a powerful synchronization method known as Virtual DOM, which compares the current page architecture to the expected page architecture and updates the appropriate components as long as the user input.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.

Is there a market for React.js programmers?
The need for React.js developers is rising at an unparalleled rate. React.js is currently used by over one million websites around the world. React is used by Fortune 400+ businesses and popular companies such as Facebook, Twitter, Glassdoor and Cloudflare.

Final thoughts:

As you’ve seen, locating and Hire React js Developer and Hire React Native developer is a difficult challenge. You will have less challenges selecting the correct fit for your projects if you identify growing offshore locations (e.g. India) and take into consideration the details above.

React 18: Things You Need To Know About React JS Latest Version

The most awaited version of React 18 is finally out now. Its team has finally revealed the alpha version of React 18 and its plan, though the official launch is still pending. This time the team has tried something and released the plan first to know their user feedback because the last version of React 17 was not that much appreciated among developers.

According to Front-end Frameworks SurveyReact JS has ranked top in the list of most loved frameworks. Thus, the developer communities expect a bit higher from the framework, so they are less appreciative of the previous launch.
ReactJS stats.pngSo, this time React 18 will be a blast. For beginners, the team is working on a new approach. They have called a panel of experts, library authors, educators, and developers to take part in a working group. Initially, it will be a small group.

I am not a part of this release but following the team on their GitHub discussion group. After gathering the information from there, I can say that they have planned much better this time.

React 17 was not able to meet the developer's community. The focus was all primarily centered on making it easier to upgrade React itself. React 18 release will be the opposite. It has a lot of features for react developers.
