Stop recompiling dependencies

Section titled Stop recompiling dependencies

With oneRepo, you can utilize shared Workspaces as source-level dependencies. This means that all import/require chains within the monorepo originate from the source files, eliminating the need to rebuild shared packages to capture changes.

Logging output from every command and tool in oneRepo is carefully grouped, documented, and prevented from overlapping parallel executions. Every line includes context, timing, and log-type information.
