Play with demo or view examples code

React Currency Input Demo


npm install react-currency-input-field


yarn add react-currency-input-field


import CurrencyInput from 'react-currency-input-field';

  placeholder="Please enter a number"
  onValueChange={(value, name) => console.log(value, name)}

Have a look in src/examples for more examples on implementing and validation.


Name Type Default Description
allowDecimals boolean true Allow decimals
allowNegativeValue boolean true Allow user to enter negative value
defaultValue number Default value
value number Programmatically set the value
onValueChange function Handle change in value
placeholder string Placeholder if no value
decimalsLimit number 2 Limit length of decimals allowed
decimalScale number Specify decimal scale for padding/trimming eg. 1.5 -> 1.50 or 1.234 -> 1.23 if decimal scale 2
fixedDecimalLength number Value will always have the specified length of decimals
prefix string Include a prefix eg. £ or $
decimalSeparator string locale default Separator between integer part and fractional part of value
groupSeparator string locale default Separator between thousand, million and billion
intlConfig object International locale config
disabled boolean false Disabled
disableAbbreviations boolean false Disable abbreviations eg. 1k -> 1,000, 2m -> 2,000,000
disableGroupSeparators boolean false Disable auto adding the group separator between values, eg. 1000 -> 1,000
maxLength number Maximum characters the user can enter
step number Incremental value change on arrow down and arrow up key press


It can parse values with abbreviations k, m and b


  • 1k = 1,000
  • 2.5m = 2,500,000
  • 3.456B = 3,456,000,000

This can be turned off by passing in disableAbbreviations.


You can change the decimal and group separators by passing in decimalSeparator and groupSeparator.


import CurrencyInput from 'react-currency-input-field';

<CurrencyInput decimalSeparator="," groupSeparator="." />;

Note: the separators cannot be a number, and decimalSeparator must be different to groupSeparator.

To turn off auto adding the group separator, add disableGroupSeparators={true}.

Intl Locale Config

This component can also accept international locale config to format the currency to locale setting.


import CurrencyInput from 'react-currency-input-field';

<CurrencyInput intlConfig={{ locale: 'en-US', currency: 'GBP' }} />;

<CurrencyInput intlConfig={{ locale: 'ja-JP', currency: 'JPY' }} />;

<CurrencyInput intlConfig={{ locale: 'en-IN', currency: 'INR' }} />;

locale should be a BCP 47 language tag, such as “en-US” or “en-IN”.

currency should be a ISO 4217 currency code, such as “USD” for the US dollar, “EUR” for the euro, or “CNY” for the Chinese RMB.

Any prefix, group separator and decimal separator options passed in will override the default locale settings.

Fixed Decimal Length

Use fixedDecimalLength so that the value will always have the specified length of decimals.

This formatting happens onBlur.

Example if fixedDecimalLength was 2:

- 1 -> 1.00
- 123 -> 1.23
- 12.3 -> 12.30
- 12.34 -> 12.34

Decimal Scale and Decimals Limit

decimalsLimit and decimalScale are similar, the difference is decimalsLimit prevents the user from typing more than the limit, and decimalScale will format the decimals onBlur to the specified length, padding or trimming as necessary.

Example: If decimal scale 2, 1.5 -> 1.50 and 1.234 -> 1.23

Format values for display

Use the formatValue function to format the values to a more user friendly string. This is useful if you are displaying the value somewhere else ie. the total of multiple inputs.

import { formatValue } from 'react-currency-input-field';

// Format using prefix, groupSeparator and decimalSeparator
const formattedValue1 = formatValue({
  value: 123456,
  groupSeparator: ',',
  decimalSeparator: '.',
  prefix: '$',

// $123,456

// Format using intl locale config
const formattedValue2 = formatValue({
  value: 500000,
  intlConfig: { locale: 'en-IN', currency: 'INR' },

// ₹5,00,000

v3.0.0 Release Notes

Breaking Changes

  • ⚠️ onChange renamed to onValueChange ⚠️
  • onBlurValue has been removed.
  • turnOffAbbreviations renamed to disableAbbreviations.
  • turnOffSeparators renamed to disableGroupSeparators.
  • precision renamed to decimalScale

Improvements in v3

  • Intl locale config can be passed in. Please note: formatting where the currency symbol is placed after the value like a suffix eg. (1 234,56 €) might cause problems, this is still in development.
  • Group separator will default to browser locale if not specified.
  • Can pass ref to the component.
  • onChange and onBlur functions can be passed in and will be called with original event.


As this component grew in usage, I started getting more bug reports and feature requests. That wasn’t a problem though, because I was always happy to fix any bugs and implement any features if I could.

However, this meant sometimes I was a bit trigger happy, and didn’t always think about how the different options interacted with each other. I found that it was getting a bit convoluted for my liking, and choices I had made earlier in development, now seemed like it could be improved.

Therefore, I took the opportunity of v3 to do a bit of tidying up for the component, in order to make it more future proof and intuitive to use.

I apologize if any of the changes cause new bugs or issues. Please let me know and I will fix asap.


Feel free to raise an issue on Github if you find a bug or have a feature request

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.

 Component Life Cycle in React

Every component in React goes through a lifecycle of events. You can think is of going through a cycle of birth, growth, and death the same as the picture below.

The phases are:

  • Initialization — Starting the journey of your component
  • Mounting — Birth of your component
  • Update — Growth of your component
  • Unmount — Death of your component

1. Initialization

This is the phase in which the component is going to start its journey. The developer has to define the props and initial state of the component. This is usually done inside the constructor method (see below to understand the initialization phase better).
