An RxJS Experiment

March 13, 2016

One of the joys of working at a startup is that everyone has to wear a lot of hats. At SalesWise this week, I got to put on the hat of getting the word out about a new product I’m really excited about SalesWise Meeting Manager. We have some folks focused on marketing, but Jason, my boss, asked if I could help them out with a little better targeting for our Twitter campaigns.

To do that, I spent a few hours earlier this week writing a node script to access the twitter API and try to find users who would be a good fit for our product based on job title. It was a one off script, and the end result of a few hours of work was something that worked, but was such a callback nightmare I hope I’ll never have to maintain that.

That evening, I was thinking about the program and remembered that I’d been talking with a fellow Front End Engineer, Leroy, at work about working with observables and using RxJS for functional reactive programming. This problem seemed like the perfect opportunity to try it out. So I did.

I eventually had to result to being a “Full Stack Overflow” engineering to figure out how to solve the problem of Twitter’s paged user searching using Rx. But after that, the rest of the programs flow just fell right out of it.

I’ve posted my work to GitHub. Feel free to check it out.

P.S. Also I want to post a shout out. Along the way, I had some of my own questions about how parts of RxJS worked. Eventually @SteveALee on Twitter kindly pointed me to an amazing Gitter group for RxJS. A great place to go and ask questions.
