What I am trying to do is download an image from google into my system repository in the project folder /download. Next, I am trying to get the image from the download repository and resize and again save the resized image in /thumbnail repository. Below is the code which I have written
//Google URL var mainuri = 'http://images.sadhguru.org/sites/default/files/media_files/iso/en/64083-natures-temples.jpg'; var dir = './download'; if (!fs.existsSync(dir)){ fs.mkdirSync(dir); } // CODE TO DOWNLOAD IMAGE FROM GOOGLE var filename = dir+'/file.jpg'; request.head(mainuri, function(err, res, body){ console.log('content-type:', res.headers['content-type']); console.log('content-length:', res.headers['content-length']); request(mainuri).pipe(fs.createWriteStream(filename)); }); var resizedir = './thumbnail'; if (!fs.existsSync(resizedir)){ fs.mkdirSync(resizedir); } //CODE TO GET IMAGE FROM '/download' REPOSITORY AND RESIZE var inputFile=require('path').join(__dirname,'../download/file.jpg'); //GET IMAGE FROM LOCAL var outFile = 'thumbnail/newfile.jpg'; // SAVE RESIZED IMAGE PATH // ------- CODE REMOVED - ERROR IS COMING HERE ----------- imageresize(inputFile, outFile); // FUNCTION THAT CONTAINS IMAGE RESIZE CODE //imageresize FUNCTION var imageresize = function(inputFile, outFile){ console.log(inputFile) // input stream let inStream = fs.createReadStream('C:/Users/rganji/caw/server/download/file.jpg'); // output stream let outStream = fs.createWriteStream(outFile, {flags: "w"}); // on error of output file being saved outStream.on('error', function() { console.log("Error"); }); // on success of output file being saved outStream.on('close', function() { console.log("Successfully saved file"); }); // input stream transformer // "info" event will be emitted on resize let transform = sharp() .resize({ width: 50, height: 50 }) .on('info', function(fileInfo) { console.log("Resizing done, file not saved"); }); inStream.pipe(transform).pipe(outStream); } If I remove the code which I commented as CODE REMOVED - ERROR IS COMING HERE, then image is getting downloaded from google. If I call imageresize function then the /download directory is getting created but I couldnt find any image in the directory.
i.e, If I call the download from google and resizeimage functions separately, i.e calling image download from google first and imageresize next then they are working fine that is I can find images in both /download and /thumbnail directories. But If I call resizeimage function after google download then I couldnt find any image in both the repositories.
