It's called the Pipeline Pattern. And as it turns out, it actually shows up in a lot of places - payments, analytics, APIs, etc. In this article, I’ll be walking you through it using my job scraper project. Which is actually a perfect use case for this pattern, as you’ll see. The Mess We're Trying to Avoid Now before I show you the pattern, let me show you what the code could look like without it. Now essentially what my scraper does is this: Scrape job listings from multiple sources Normalize them (i.e., clean them up) Score them based on keywords (The most relevant to my skillset get the highest scores) Save them to a database. So initially what I might have done, was something like this (simplified): for _ , raw := range rawJobs { // normalize raw . Title = strings . TrimSpace ( raw . Title ) raw . Location = strings .…
