Reinventing the BFF: how Yandex Market reworked its client service architecture
summary
Describes how Yandex.Market redesigned its client-facing backend-for-frontend: a Node.js service that handled thousands of RPS and combined API gateway and HTML rendering was decomposed and parallelized to move work away from what Node.js handles poorly. Covers migration techniques that preserved uptime and latency, avoided a full rewrite, maintained developer experience, and introduced shared contracts and code-sharing with mobile teams.
