![]() The final app will look something like the following: To follow through, you can find the source code in this repo and try the live demo. The template engine (HBS) would generate HTML and display the image on the client-side (frontend) of the application. In this tutorial, you will learn how to use technologies like Express as the server with the post method to send this image to Cloudinary. Cloudinary as a tool provides such a feature making it possible to store all your media library in the cloud. The options include the blob types (mime-type) which can be application/json, text/plain, image/png, and so on.Uploading media images to a central location found in forms and creating your media profile on social media and other applications on the web is necessary to capture user input. In the above code, the array is the blob string value, object values, or a mix of the values we want to convert to a blob. Here’s the syntax: new Blob(array, options) The blob() constructor returns a new blob object. To create a blob, we use the blob() constructor. These packages give developers access to upload and download data directly to and from cloud storage, which - especially for large files like blobs - is more efficient. To download, upload, and read blobs in React Native, we can use either the react-native-fs or react-native-blob-util package. It stores binary data as a single entity. Creating and saving files with react-native-blob-utilīlob is short for “Binary Large Object.” This data type holds multimedia objects like images and videos, GIFs, and audio.Managing cloud data with react-native-blob-util.Reading files with readDir and readFiles. ![]() Creating and saving files with react-native-fs.Managing cloud data with react-native-fs.This article will explore how to manage cloud data in React Native by using these two packages to fetch and handle blobs, as well as to create, save, and read files. In other words, they make file access and data transfer more accessible and efficient for React Native developers, especially for large files like blobs. These packages provide native file system access for React Native. This is where the react-native-fs and react-native-blob-util packages come into play. These operations could include creating, saving, and editing a file, or uploading or downloading files from the cloud. Occasionally, when working with React Native, we might need to access our device’s file system to perform certain operations. ![]() See this resource for more information about blobs and how to read blob content. ![]() How to fetch and handle blob data in React NativeĮditor’s note: This post was updated on 7 June 2023 to include information on how to create a blob and instructions for using the react-native-blob-util package to download PDFs from the cloud. I'm also skilled with React for web, React Native for Android apps, and Tailwind CSS. I am highly skilled in HTML, CSS, and JS to build web-accessible and progressive apps.
