A simple images uploader applied Render Props pattern with react


The simple images uploader applied Render Props pattern. (You can read more about this pattern here).

This approach allows you to fully control UI component and behaviours.

See the intro blog post

Package Quality



npm install --save react-images-uploading


yarn add react-images-uploading


You can check out the basic demo here:


import React from 'react';
import ImageUploading from 'react-images-uploading';

export function App() {
  const [images, setImages] = React.useState([]);
  const maxNumber = 69;

  const onChange = (imageList, addUpdateIndex) => {
    // data for submit
    console.log(imageList, addUpdateIndex);

  return (
    <div className="App">
        }) => (
          // write your building UI
          <div className="upload__image-wrapper">
              style={isDragging ? { color: 'red' } : undefined}
              Click or Drop here
            <button onClick={onImageRemoveAll}>Remove all images</button>
            {imageList.map((image, index) => (
              <div key={index} className="image-item">
                <img src={image['data_url']} alt="" width="100" />
                <div className="image-item__btn-wrapper">
                  <button onClick={() => onImageUpdate(index)}>Update</button>
                  <button onClick={() => onImageRemove(index)}>Remove</button>


  {({ imageList, onImageUpload, onImageRemoveAll, errors }) => (
    errors && <div>
      {errors.maxNumber && <span>Number of selected images exceed maxNumber</span>}
      {errors.acceptType && <span>Your selected file type is not allow</span>}
      {errors.maxFileSize && <span>Selected file size exceed maxFileSize</span>}
      {errors.resolution && <span>Selected file is not match your desired resolution</span>}

Drag and Drop

  {({ imageList, dragProps, isDragging }) => (
    <div {...dragProps}>
      {isDragging ? "Drop here please" : "Upload space"}
      {imageList.map((image, index) => (
        <img key={index} src={image.data_url} />


parameter type options default description
value array [] List of images
onChange function (imageList, addUpdateIndex) => void Called when add, update or delete action is called
dataURLKey string dataURL Customized field name that base64 of selected image is assigned to
multiple boolean false Set true for multiple chooses
maxNumber number 1000 Number of images user can select if mode = multiple
onError function (errors, files) => void Called when it has errors
acceptType array [‘jpg’, ‘gif’, ‘png’] [] The file extension(s) to upload
maxFileSize number Max image size (Byte) and it is used in validation
resolutionType string ‘absolute’ ‘less’ ‘more’
resolutionWidth number > 0
resolutionHeight number > 0



value description
absolute image’s width === resolutionWidth && image’s height === resolutionHeight
ratio (resolutionWidth / resolutionHeight) === (image width / image height)
less image’s width < resolutionWidth && image’s height < resolutionHeight
more image’s width > resolutionWidth && image’s height > resolutionHeight

Exported options

parameter type description
imageList array List of images to render.
onImageUpload function Called when an element is clicks and triggers to open a file dialog
onImageRemoveAll function Called when removing all images
onImageUpdate (updateIndex: number) => void Called when updating an image at updateIndex.

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.
