laminas/laminas-development-mode
Laminas Development Mode provides a simple command-line toggle for switching a Laminas MVC application between production and development configurations, enabling development modules, debug settings, and config caching behavior without manual config file edits.
config/development.config.php from its .dist). The real decision is whether to spend engineering time reimplementing ~50 lines of file-toggling logic or adopt a maintained package. For a Laminas MVC shop, adoption is the cheaper path; for anyone else, a Composer script or Makefile target is cheaper still.development.config.php.dist plus a gitignored generated file — not to 12-factor env vars. That choice ripples into deployment, container images, and secret handling, so it belongs in an architecture decision record, not a sprint ticket.development-mode enable|disable replaces "read the README, copy this file, don't commit it" tribal knowledge with a single documented command. Measurable as reduced setup friction for new hires and fewer "works on my machine" tickets.development.config.php. Safe toggling plus status reporting gives a verifiable pre-deploy check.status command can gate builds and deployments. That is a small but real automation win versus a human remembering to delete a file.Adopt it when all of the following hold:
config/development.config.php.dist convention — the package is a thin convenience over a pattern you've already bought into.Look elsewhere when:
vlucas/phpdotenv, container env vars, or a real config/secrets service.To executives: This is a zero-cost, BSD-licensed developer convenience, not a platform investment. It eliminates a recurring class of self-inflicted outages — local debug configuration leaking into production — by making the switch between dev and prod configuration a single auditable command instead of a manual file edit. Cost is effectively nil, runtime risk is nil (it's dev-only tooling, never loaded in production requests), and scope is deliberately narrow. The honest framing: it is a small quality-of-life win that only applies if we are already standardized on Laminas MVC. It should not appear on a roadmap as a line item, and it is not a reason to choose or stay on the framework.
To engineering: One command (enable / disable / status) replaces copy-the-dist-file-and-remember-not-to-commit. It's scriptable, so it drops into CI as a pre-deploy assertion; it adds no production dependency; and because the behavior is trivial, the lock-in is near zero — if the package stalls, we reimplement it in an afternoon. The tradeoff to accept consciously: it hardcodes a two-state dev/prod model and a filesystem-based config convention. If we're moving toward containerized deploys with environment variables, this package is a bridge, not a destination — adopt it to remove toil now, and expect to retire it when the config strategy changes.
