devenv-ecosystem

Patterns for devenv configuration — language setup, services, tooling (git-hooks, scripts, processes), outputs, and profiles. For Nix language syntax, flake structure, or general NixOS module patterns, see nix-ecosystem instead; this skill covers only what is devenv-specific.

devenv 2.0

Released March 2026. Two changes affect existing configs directly:

• The native process manager is now the default, replacing process-compose. A config that assumes process-compose behavior (health checks, depends_on, readiness probes) silently gets the native manager instead unless process.manager.implementation = "process-compose"; is set explicitly — there is no error, just different runtime behavior for devenv up. To keep process-compose:

  process.manager.implementation = "process-compose";
