![]() The full example of how this code can be used in an upload component using ReactJs. We can use any percentage of compressing we need. This code compresses the images to 80% of their original quality. To install the package, type one of the following commands based on your package managerįor Yarn: yarn add compressorjs Add the particular code block to your projectĪdd the code to your component before uploading. Add the particular code block to your project.If you don't upload professional photos, that should not be a problem. But you should keep in mind several things if you resize image on the client: You will have only 8bits per channel (jpeg can have better dynamic range, about 12 bits). To compress your images follow these three simple steps: In modern browser you can use canvas to load/save image data. We can resize, compress and convert the images based on our requirements. I came across an amazing image compression package for Javascript called compressorjs. So, I started looking into lossless compression techniques for images on the client-side. This consumes most of our time while uploading. And it is supported by all browsers.įirst we will create a new project in Node.While uploading the images to the block storage (or) S3 storage, the full images when captured through the phone (Pixel 3 or others) camera, has a size up to 3 MB. The image format that we are going to use in this example is WebP, which offers compression greater than png and jpg, which helps to load web pages more quickly. Sharp is a module for Node.js to convert images of the most diverse formats and varied dimensions to a smaller size, without having to worry about the color space, channels and alpha transparency, because all of these are treated correctly. By combining Express.js with multer, we will be able to easily implement the file upload feature. Multer is a middleware for handling multipart/form-data that is mainly used to upload files. Nowadays uploading images is one of the most basic operations of all applications. ![]() Today I'm going to focus on multer and sharp. I don't think I need to talk about Express.js because everyone who uses Node.js has used this framework at some point. However, I will show that with a simple Express.js api we can upload an image, change the Mime Type and still decrease its size. One of the most common is to compress images. ![]() Currently, I feel that the market is increasingly oriented towards the use of third-party services to make part of our pipeline. ![]()
