In this chapter, we created an API that can set up meetings between users taking into account their matching history and the pair of longitude and latitude, while providing them the chance to give feedback on how it went-essential information which can be used in many ways to further improve the algorithm!
We hope you learned about many interesting and practical concepts, such as making geo queries, testing time-sensitive code, sending e-mails with style, and tasks that run periodically.
Besides the technical bits, hope you had fun and perhaps were able to spark some insight on the framework behind match-making apps!
Next on, we'll see how Koa.js works by leveraging the power of generators, bringing the readability of synchronous code on top of the async features of Node.js.
