Managing Dependencies#

Metax V3 uses uv for managing Python dependencies. Dependency constraints are defined in pyproject.toml. The list of installed dependencies is stored in uv.lock which includes hashes of all dependencies, if the integrity of the dependency-tree ever needs to be verified.

For full documentation of uv, visit the official documentation.

Installing uv#

See the installation instructions. If you already have pipx installed, you can install uv with pipx install uv.

Updating dependencies#

Add development dependencies#

uv add --dev <package>

Add application dependencies#

uv add <package>

Update all dependencies within constraints defined in pyproject.toml#

uv lock --upgrade

Remove dependencies#

uv remove [--dev] <package>

Re-generate requirements#

After any modification to dependencies, re-generate requirements with 

uv export --frozen --no-hashes --no-annotate --format requirements.txt --no-dev > requirements.txt
uv export --frozen --no-hashes --no-annotate --format requirements.txt > dev-requirements.txt
