Open Sourcing Yelp Love

Encouraging positivity has been a central pillar to Yelp’s culture from the beginning. If a teammate rolls out a huge feature, helps you out in a bind, or just makes a funny joke, we believe you should be able to show them a small token of appreciation. That’s why we developed an internal tool called Yelp Love, a web application for sending notes of appreciation (aka love) to your coworkers within Yelp. Yelp Love started as a Hackathon effort back in 2013. Over the course of two hackathons, we rolled out Yelp Love to the entire company. Since its deployment,...

Announcing Docker Hook Support for Pre-Commit

You can see a list of many of these here. Pre-commit has been invaluable in increasing the productivity of Yelp’s code base and code-reviews by making style issues a thing of the past and allowing us to easily check for broken and deprecated code usage with a variety of code linters. While pre-commit supports a number of popular languages, the goal of pre-commit...
