  1. Solving behavioral complexity with FRP [rus]: deep dive into how we apply FRP when building Grammarly Editor

At Grammarly, we have tried different approaches to handle behavioral complexity. We made a long journey from callback hell to FRP, and from dynamic to static typing. We will discuss how FRP helped us build stable high-loaded front-end applications with complex async actions for millions of daily users.

  1. How to Use Bazel to Manage Monorepos: The Grammarly Front-End Team's Experience [rus]: The talk is about why we decided to use monorepo for Grammarly OnlineEditor and why chose Bazel to manage it.

At some point, we reached the limit of the existing build process in the Grammarly Editor monorepo. Build tools required too much time to support, and each new package increased build time and made dependency management harder. To move further, we had to rethink the architecture of the build process. Our solution: We switched to Bazel. In this talk, I will share our findings and how we made the architecture of the build process scalable and predictable.

  1. Grokking System Design interview for Front-end engineer (ukr)
