@esh-vibe/version-sync

Sync Bun, Node, and Playwright versions from your project into a Dockerfile.

What It Syncs

• BUN_VERSION: from package.json -> packageManager (for example [email protected])
• NODE_VERSION: from .nvmrc (leading v is removed, so v24.13.0 becomes 24.13.0)
• PLAYWRIGHT_VERSION: from node_modules by reading one of:
  • @playwright/test
  • playwright
  • playwright-core

Installation

pnpm add -D @esh-vibe/version-sync

Or run it directly:

npx version-sync

Usage

# Sync versions to Dockerfile in current directory
npx version-sync

# Sync versions to a specific Dockerfile
npx version-sync docker/Dockerfile.prod

# Check mode for CI
npx version-sync --check

Options

• [dockerfile]: Path to Dockerfile (default: Dockerfile)
• --root <path>: Project root containing package.json, .nvmrc, and node_modules (default: current directory)
• --check: Check if Dockerfile ARGs are in sync without updating. Exits with code 1 if not in sync.

Dockerfile Requirements

Your Dockerfile should include these ARGs:

ARG BUN_VERSION=1.0.0
ARG NODE_VERSION=24.13.0
ARG PLAYWRIGHT_VERSION=1.55.0

API

import {
  getVersions,
  syncVersionsToDockerfile,
  checkVersionsInDockerfile,
} from "@esh-vibe/version-sync";

const versions = getVersions(".");
syncVersionsToDockerfile("Dockerfile", versions);
