Smart Optimizer

Smart Optimizer is an efficient image compression and resizing middleware for Node.js applications. Using TypeScript, Multer, Tsup, and Sharp, it allows you to compress images before uploading, manage file sizes, and specify image quality. Perfect for optimizing image uploads in your web applications.

Features

• File Compression: Compress images before uploading with a boolean flag.
• File Size Ratio: Automatically create multiple image sizes based on specified ratios.
• Image Quality: Set image quality from 1 to 100.
• Local Path: Specify a local path where processed images are saved.

Installation

Install the package using npm:

npm install smart-optimizer

Usage

Setting Up Middleware

To use Smart Optimizer as middleware in your application, follow these steps:

1. Import Dependencies:

const UploadManager = require("smart-optimizer").default;

OR

import uploadManager from 'smart-optimizer'

2. Initialize Middleware:

exports.uploadPic = async (req, res, next) => {
 let imagePath = [];
 const uploader = new UploadManager({
   fileCompression: true,
   fileResizeRatio : [[100,100],[200,200]], //optional
   allowExtension: ["jpeg", "jpg", "png"], // you can add more extension also.
   imageQuality: 70,
   localPath: "public/img", 
 });
 uploader.uploadFiles(req, res, function (err, uploadResponse) {
   if (err) {
     console.log("Error:", err);
     return next(err);
   }
   if (uploadResponse.code === 200) {
     req.file = uploadResponse.data[0];
     next();
   } else {
     console.log("Upload failed with code:", err);
     res.status(500).send("Upload failed");
   }
 });
};

3. Routes

app.post('/upload',uploadPic, (req, res) => {
   // Respond with the details of the processed image
   if (req.file) {
       console.log("Upload files", req.file);
   } else {
       console.log("No Files  uploaaded");
   }
   res.status(200).json({
       success: true,
       message: "Image",
   });
});

Return Object

After the image is processed and uploaded, the middleware will add the processed file information to req.file. This object contains details about the uploaded file, such as its filename, size, and path.
