What is recompile_buster?

Recompile Buster is a Mix task for Elixir projects that analyzes your xref graph to identify modules causing excessive recompilation cascades. Run `mix recompile_buster` to get a ranked list of top offenders by transitive deps and recompiles triggered, or use `--explain` on a file for a breakdown of its impact. It solves the pain of slow builds in growing codebases by surfacing compile-time coupling, with options like `--limit` and `--fail-above` for CI gates—add it as an elixir mix github dependency in dev mode.

Why is it gaining traction?

Unlike basic mix tasks elixir or xref outputs, it quantifies recompilation hotspots with actionable metrics like transitive deps up to three levels, plus per-file explanations linking deps to rebuilds. Developers hook on the CI fail threshold to enforce hygiene without manual audits, and the simple CLI fits right into mix task run workflows. It's a targeted mix task compiler analyzer that turns vague slowness into fixable lists.

Who should use this?

Elixir backend teams on Phoenix apps where `phx new` scaffolds balloon into recomp hell on every tweak. Maintainers of mix github dependency-heavy repos chasing faster iteration, or CI pipelines needing mix coveralls github-style gates for compile perf. Ideal for devs tired of "cross mix github" wildcards in large monorepos.

Verdict

Grab it for any mid-sized Elixir project—19 stars and 1.0% credibility score signal early days, but crisp docs and MIT license make it a low-risk mix github dependency trial. Solid for spotting issues before they kill productivity, though watch for edge cases in massive graphs.
