POPrompt a csv file to download as pop up using node.js and node-csv-parser (node module)
text
Body
copied!<p>Recently I have started working with node.js. While going through a requirement in one of my projects I am facing an issue where I should be able to write some data to a csv file dynamically and let it prompt as a popup to download for user (with save and cancel options - as we normally see). After googling for some time I decided to use csv npm module <a href="https://github.com/wdavidw/node-csv-parser" rel="noreferrer">https://github.com/wdavidw/node-csv-parser</a>. I am able to write data into a file and save it using this module. I want to prompt a popup for saving this file with/without saving the file.</p> <p>my code looks something like this: </p> <pre><code> // Sample Data var data = [["id", "subject1", "subject2", "subject3"], ["jack", 85, 90, 68], ["sam", 77, 89, 69]] // Server Side Code var csv = require('../../node_modules/csv'); var fs = require('fs'); createCSV = function(data, callback) { csv().from(data).to(fs.createWriteStream('D:/test.csv')) // writing to a file } // Client side call sample $("#exportToCSV").click(function() { callToServer.createCSV(data); return false; }); </code></pre> <p>This is working good as far as writing the csv file is concerned. </p> <ul> <li>I want to prompt this file immediately to download for users.</li> <li>If this can be done without saving the file, that will be great.</li> <li>How can I set content-type and content-disposition as we do in PHP</li> </ul> <p>Any help is greatly appreciated. -Thanks</p>
