Phoenix LiveView enables real-time user experiences with server-rendered HTML.Īmong its greatest pros, the staff engineer lists: The tech stack also allowed for increasing the system’s throughput right away.įor Spotify’s debugging portal, Kemp decided to use yet another Elixir-based weapon: the Phoenix LiveView library. indicating the service’s bottlenecks at the double workload, without a need for heavy instrumentation. thousands of requests per second.Īfter a few days of research, Kemp concluded that both Elixir programming language and the BEAM virtual machine it was based on, could indeed address his pain points, e.g. Back then, he hinted at the language and its advantages as an alternative to Kemp’s struggles with a JVM-built backend service handling heavy traffic, i.e.

Several months earlier, Spotify hired a new team member who was well-versed in Elixir. Phoenix LiveView: from proof of concept to a game-changer The whole operation, done in a standard way, seemed daunting. And - let us remember - there was virtually no time. Designing it to access the crucial-yet-basic insights into the app’s performance would be a waste of time. Such operation would demand involving two people: both a frontend and a backend developer.īut given the fact that the portal’s audience would be the Spotify devs themselves, there was no need for things like a fancy UI to please anybody else. Up till that moment, the standard approach to this problem would have been building a single-page app in React and a JSON API backend.

But the internal app seemed critical for measuring the product’s performance and, what seemed logical, success. Most of their attention is spent on fixing bugs, end-to-end testing, last-minute checks, etc. The main challenge Kemp was facing, was that in periods right before the launch teams are reluctant to give love to its internal tools. The portal’s task was to make the team see what was being booked by the customers, and troubleshoot when needed. “We needed an internal debugging portal”, said Spotify’s staff engineer Joel Kemp on the Thinking Elixir podcast. In the last week before the launch, the devs realized they needed an internal application managing the service. In 2021, Spotify was nearing the release of a major product: an ad platform for artists letting them promote their work.

What did make the devs at Spotify bet on Elixir? As it often happens, the decision to give the functional programming language a try came with a last-minute need. Elixir at Spotify: a need as a mother of invention This, in turn, calls for a robust tech stack.

The platform’s ever-rising traffic requires the ability to handle thousands of concurrent requests every second.

The platform offers a suite of services for music & podcast fans (songs, full releases, podcasts & playlists), as well as for the artists and content creators (advertising, metrics, etc.).
