Overview

The pnpm lockfile that pins exact dependency versions and integrity hashes for the Dify frontend application to ensure reproducible installs.

Description

web/pnpm-lock.yaml is an auto-generated lockfile produced by pnpm (lockfile version 9.0) that records the exact resolved versions, registry URLs, and integrity checksums for every direct and transitive dependency of the Dify frontend. At 15,614 lines, it captures the full dependency tree derived from web/package.json.

The lockfile includes:

• Settings: autoInstallPeers: true and excludeLinksFromLockfile: false, which control how pnpm handles peer dependencies and workspace links.
• Overrides: Mirrors the pnpm.overrides and resolutions from package.json, including @nolyfill replacements for unnecessary polyfills and security-related version pins for packages like prismjs, pbkdf2, and esbuild.
• Package entries: Each resolved package includes its version, resolution URL, engine requirements, peer dependency information, and an integrity hash for verification.

This file guarantees that every developer and CI environment installs the identical dependency tree, preventing "works on my machine" issues caused by version drift.

Usage

Developers should not edit this file manually. It is regenerated automatically by pnpm whenever pnpm install, pnpm add, pnpm update, or pnpm remove is run. The lockfile should always be committed to version control so that CI pipelines and other developers reproduce the same dependency resolution. If merge conflicts arise in this file, the recommended approach is to delete it and run pnpm install to regenerate it.

I/O Contract

Inputs

Name	Type	Required	Description
package.json	JSON file	Yes	The package manifest whose dependencies are resolved and locked
pnpm CLI commands	shell	Yes	Commands like pnpm install that trigger lockfile generation
npm registry	HTTP	Yes	The package registry from which versions and integrity hashes are fetched

Outputs

Name	Type	Description
Locked dependency tree	YAML file	Exact versions and integrity hashes for all direct and transitive dependencies
Reproducible installs	node_modules	Guarantees identical node_modules contents across environments

Usage Examples

# Install dependencies using the lockfile (frozen for CI)
pnpm install --frozen-lockfile

# Update a dependency (regenerates the lockfile)
pnpm update react

# Add a new dependency (regenerates the lockfile)
pnpm add some-package

# Regenerate lockfile after merge conflicts
rm web/pnpm-lock.yaml && pnpm install
