Where to Start?
summary
Hands-on guide for getting productive in a large Clojure codebase: Metabase is ~98k LOC and the workflow centers on REPL-first debugging (beware stale defs, macros, and threading pitfalls). Practical tips cover spinning a runnable REPL, drawing namespace graphs, using tap to capture intermediate values, preferring use spec over schema for dynamic re-eval, writing clear docs/tests/notebooks, designing lightweight scaffolding, linting, and an onboarding task plan. Watch for actionable techniques and concrete tooling tradeoffs.
