devenv.nix

The only required file for specifying the developer environment.

Generated by devenv init and thoroughly documented, starting with the basics.

devenv.local.nix

Same as devenv.nix, but not meant to be committed into the Git repository so that developers can override some things for their local use case.

devenv.local.yaml

Added in 1.10

Same as devenv.yaml, but not meant to be committed into the Git repository so that developers can override some things for their local use case.

devenv.yaml

Configuration for inputs and imports, allowing you to specify dependencies and how to compose them.

You can require a specific devenv version to make sure all developers use a compatible version:

devenv.yaml

# Enforce CLI matches the modules version
require_version: true

# Or use an explicit constraint
require_version: ">=2.1"

See devenv.yaml reference for details.

devenv.lock

Pinned inputs, making sure your developer environment is reproducible.

.envrc

direnv integration logic.

See direnv integration to set up your shell to automatically activate the developer environment when you cd into it.

Environment Variables
