The CI Diet Plan: 5 Code Smells to Eliminate—& How to Keep Them Off for Good

Barrel files, wildcard imports, and deep-relative paths can keep your CI pipeline in the red no matter how smart your Nx/Bazel/Turborepo cache is. This guide shows you how to detect five high-impact “build-bloat” smells, track their burndown in Codemod Insights, and reclaim double-digit minutes from every build—without touching your build-tool flags.

Imperative vs. Declarative Codemods in Large-Scale Migrations

Before you start swapping out a design system or upgrading a framework across thousands of files, it pays to pick the right approach for each change.

In this post, we’ll show you when to reach for declarative codemods versus imperative ones and how to combine them in a real-world migration.

“Codemodable”: The elegant code that grows with you

When you start a greenfield project, AI allows you to ship at the speed of thought. However, as your project grows in size, your code may not evolve as quickly as you would like. It doesn't have to be this way. Andrew and I would love to refer to such code as "elegant," which has a straightforward definition.
