The resulting script should be something like below (this is also on Github).Ĭonst puppeteer = require ( ' puppeteer ' ) ( async () => else if ( await page. Hit ‘Record’ on the extension and run through your scenario above, you should get something like these: It won’t generate perfect code, but it’s good enough to get iterating and results. I love doing less work whenever I can, so I installed the Headless Recorder extension on my Chrome and started recording my steps. Overture (Composing the Script) Jumpstarting the script I also highly recommend this post on building a scheduled news crawler. Took some inspiration also from how to get started with Puppeteer from this article. With that test plan/script out of the way, here’s what the end result will look like (GIF below, might take a few seconds to load): If the website allows you to pick ‘Regular Delivery’, notify us.(their backend API appears to throw a 500 Service Unavailable on occasion if there is only one item in your bag and it’s out of stock).If the website errors out or tells us some items are out of stock, do nothing.We enter our zipcode and hit ‘Calculate Delivery Cost’.At the shopping bag page, we will ‘continue to checkout’. ![]() Here in the US we pay a flat fee for shipping, so it’s something to think about!.The reason I say either is you get to decide if you want to be notified when at least one item you want is in-stock and deliverable, or only to be notifed when all are in stock.Either add more items to the bag, or click on ‘Continue to bag’.Open Chromium and visit specific product links, for example: this random mirror.It’s helpful to have some idea in mind what you want to achieve before using Headless Recorder to generate the script. Puppeteer (to automatically visit and check for in-stock/delivery items)īefore starting to automate, similar to User acceptance testing, let’s note what we want to do.NPM (install Node packages like Puppeteer and Nodemailer).I’m always interested in learning, so feel free to leave some feedback below. As such you might see better ways of doing certain things, or me breaking some best practices. If an item is in stock, have the app send an email.īefore diving in I wanted to mention I’m not very skilled at JS and best-practices, and that this was meant to be a quick script to automate a manual process for individual use, so some parts are a hacky. We’ll also use Headless Recorder (formerly Puppeteer Recorder) to jumpstart our automation by recording your browser actions to generate a script. Puppeteer is a browser automation and testing framework that allows you to script and manipulate an instance of Chromium. So instead of manually checking if an item is in stock every few days or so (what fun is that?), I decided to learn how to use Puppeteer to write a Node JS script that would programmatically control Chromium (open source project that Google Chrome is based on) to add an item to cart, type in the ZIP code we want and check if there’s the item we want in stock. You can also just skip the rest of this blog post if you just want to read the code here.(for more experienced devs looking to see how I achieved certain things, feel free to speed read and look at keywords in bold) Be sure to at least find ways to support the frontliners in the healthcare system, your local restaurants, tip the hard working delivery drivers and essential workers in the service industry.) (Side note: Yes, I realize this is a real first-world problem, not having furniture in stock at IKEA.Plus, you’ll notice the guidance from IKEA’s FAQ above is to use their app to check for in-stock items at your local store.īut it seems like the only proper way to check if an item is in stock is to add an item to cart, checkout, enter your ZIP code and if you’re lucky, you get an option to pick a delivery date. However due to COVID-19 the global supply chains have been impacted such that essentials for a new home are out of stock*. ![]() Recently I’ve moved and wanted to buy some furniture from IKEA. we are currently experiencing supply delays due to COVID-19
