Implementation:BerriAI Litellm NPM Lock

Overview

Description

The package-lock.json file is an automatically generated NPM dependency lock file that ensures deterministic, reproducible installations of JavaScript/Node.js dependencies used by the LiteLLM project. It locks the exact versions and integrity hashes of all direct and transitive dependencies.

The project's JavaScript dependencies support the LiteLLM Proxy UI Dashboard, which is a Next.js application built and served from litellm/proxy/_experimental/out/. The lock file is associated with the root-level package.json (not shown separately but implied by the lock file).

This file should never be manually edited. It is generated and updated automatically by npm install.

Usage

The lock file is consumed by npm ci or npm install during the UI build process in CI and local development. The CircleCI pipeline includes a ui_build job that installs these dependencies before building the Next.js dashboard.

Schema Fields

Root Fields

Field	Type	Description
name	String	Package name: "litellm"
lockfileVersion	Integer	Lock file format version: 3 (npm v7+)
requires	Boolean	Whether the package has a requires field
packages	Object	Map of all installed packages with their resolved metadata

Direct Dependencies

Package	Purpose

Package Entry Fields

Each entry under packages follows the npm lockfile v3 schema:

Field	Type	Description
version	String	Resolved package version
resolved	String	URL the package was fetched from
integrity	String	Subresource Integrity (SRI) hash for verification

license	String	Package license (e.g., "MIT")
dependencies	Object	Transitive dependencies of this package
engines	Object	Node.js version requirements
funding	Object	Funding information for the package

Usage Examples

CI: UI Build Process

The CircleCI configuration includes a ui_build job that uses this lock file:

# The ui_build job installs npm dependencies using the lock file
# to ensure reproducible builds, then builds the Next.js UI dashboard.
# The ui_unit_tests job depends on ui_build completing first.

Local Development

# Install exact versions from lock file:
npm ci

# Or install and potentially update lock file:
npm install
