devenv 1.10 brings new capabilities for structuring monorepo projects:
- absolute/parent path imports
- git root prefixing
- devenv.yaml imports
- devenv.local.yaml support
- monorepo guide
Absolute / parent path imports
Paths starting with / are now resolved from your git repository root, and parent imports are also supported (#998).
This lets services consistently reference shared configurations:
This is particularly handy in monorepos where projects are nested at different depths:
All three projects reference /nix regardless of their location.
Git root prefixing
The new config.git.root variable provides the git repository root path for specifying working directories in tasks and processes (#1850, #316).
services/api/devenv.nix
{ config, ... }: { tasks."db:migrate" = { exec = "npm run migrate"; cwd = "${config.git.root}/services/api"; }; processes.api = { exec = "npm start"; cwd = "${config.git.root}/services/api"; }; }Useful when reusing modules across different directories.
devenv.yaml imports
Most upvoted feature with 75 votes (#14) is here!
Local imports now load and merge both devenv.nix and devenv.yaml configurations:
The API service inherits the allowUnfree setting and nixpkgs input. Note that this merging only applies to local filesystem imports — imports from inputs still only load Nix configurations (#2205).
devenv.local.yaml support
Just like devenv.local.nix, you can now use devenv.local.yaml for developer-specific overrides (#817).
Both files are git-ignored for local overrides:
