A simple images uploader applied Render Props pattern with react

react-images-uploading

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

Installation

npm

npm install --save react-images-uploading

yarn

yarn add react-images-uploading

Usage

You can check out the basic demo here:

Basic

import React from 'react';

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

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

  return (
    <div className="App">
      <ImageUploading
        multiple
        value={images}
        onChange={onChange}
        maxNumber={maxNumber}
        dataURLKey="data_url"
      >
        {({
          imageList,

          onImageUpdate,
          onImageRemove,
          isDragging,
          dragProps,
        }) => (
          // write your building UI
          <div className="upload__image-wrapper">

            {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>

          </div>
        )}
      </ImageUploading>
    </div>
  );
}

Validation

...
  {({ 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>}
    </div>
  )}
...

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} />
      ))}
    </div>
  )}
...

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.
