The project initialises with a serverless.yml file. Let’s make a new serverless project: $ serverless create -template aws-nodejs -path donkeyjob $ cd donkeyjob Serverless will take all the pain out of configuring our AWS environment and allow us to develop and test locally until we’re finally ready to deploy everything to the cloud. Take a look at the Quick Start guide to the serverless framework and make sure you have completed the prerequisites.
AWS LAMBDA WEBSCRAPER HOW TO
It’s a very handy thing to know how to do. Scraping is the term given to the process of grabbing the HTML from a page and programatically extracting information from it, for example, new recipes added, the day’s stock prices, weather reports, betting odds, sports outcomes, new job listings, etc. Of course, extracting this information from the site can be easily done with your eyes by simply navigating to the page and having a look, but imagine you want to check the same thing every day and build a spreadsheet from the data over a long period.

I’ll explain it as I go! Later, we’ll also use another AWS feature, DynamoDB, to store data from one day to the next. We’ll use the serverless framework to build our Lambda function. A Lambda function is simply a function that lives in the cloud, can run whenever it’s needed and is triggered by events or API calls. You don’t have to worry about building and managing servers as Amazon does all that for you. on Amazon’s computers), allowing you to build serverless applications that scale automatically. The principle of AWS is that all parts of your application from storage to computing power are provisioned by Amazon and hosted in a cloud environment (i.e. If you have never used Amazon Web Services before, read about Lambda here, sign up for AWS, and then take a look at this article which walks you through making your first Lambda function. My scraper will check daily whether The Donkey Sanctuary has any new job listings and will send me an SMS if they do.īefore you start, you should be familiar with: In this tutorial, I’ll walk you through the basics of making a web scraper with Node.js and AWS Lambda.
