Fast Python dependency resolution using uv for Serverless Framework.

Generates requirements.txt from pyproject.toml using uv's fast resolver, then works with serverless-python-requirements for Lambda packaging.

Installation

``bash
npm install --save-dev serverless-uv-requirements serverless-python-requirements
`

Setup

`yaml


serverless.yml

plugins:
- serverless-uv-requirements
- serverless-python-requirements

custom:
uv:
mode: compile
source: pyproject.toml
output: requirements.txt

pythonRequirements:
dockerizePip: non-linux
`

`toml


pyproject.toml


[project]
dependencies = [
"fastapi>=0.104.0",
"pydantic>=2.0.0",
]
`

Configuration

`yaml
custom:
uv:
mode: compile # 'compile' or 'freeze'
source: pyproject.toml # Input file
output: requirements.txt # Output file
verbose: false # Enable verbose logging
skipIfMissing: false # Skip if uv not available
`

Requirements

- uv: curl -LsSf https://astral.sh/uv/install.sh | sh
- Serverless Framework: >=3.0.0

How it works

1. uv resolves dependencies from pyproject.toml to requirements.txt` (10-100x faster than pip)
2. serverless-python-requirements handles Lambda packaging
