Opennextjs Cli

---

Overview

OpenNext.js CLI is a comprehensive, interactive command-line tool that simplifies setting up and managing OpenNext.js projects for Cloudflare Workers. Built with modern UX principles using @clack/prompts (same as next-forge), it provides a beautiful, intuitive interface for project setup, configuration, deployment, and maintenance.

What is OpenNext.js?

OpenNext.js is an open-source adapter that enables deploying Next.js applications to various platforms, including Cloudflare Workers. This CLI tool automates the entire setup and configuration process, making it as easy as create-next-app.

Packages

This monorepo contains 2 npm packages that share the same GitHub repository but are published separately:

1. @jsonbored/opennextjs-cli - CLI Tool

The main command-line interface for setting up and managing OpenNext.js projects.

Installation:

npm install -g @jsonbored/opennextjs-cli
# or
pnpm add -g @jsonbored/opennextjs-cli

Alias: onjs (shorter command)

Documentation: See packages/opennextjs-cli/README.md for complete CLI documentation.

2. @jsonbored/opennextjs-mcp - MCP Server

Model Context Protocol server that enables AI tools to interact with OpenNext.js projects.

Installation:

npm install -g @jsonbored/opennextjs-mcp

Documentation: See packages/opennextjs-mcp/README.md for complete MCP documentation.

Note: The MCP server is automatically configured when you run opennextjs-cli mcp setup.

Requirements

• Node.js 18.0.0 or higher
• pnpm 8.0.0+ (recommended) or npm/yarn/bun
• Cloudflare Account (for deployment)
• Wrangler CLI (installed automatically)

Caching Strategies

The CLI supports multiple caching strategies:

Strategy	Description	Use Case
static-assets	SSG-only, no R2 needed	Simple static sites
r2	R2 Incremental Cache	Most Next.js apps (recommended)
r2-do-queue	ISR with time-based revalidation	Dynamic content with ISR
r2-do-queue-tag-cache	Full-featured with on-demand revalidation	Complex apps with on-demand ISR

Roadmap

Completed:

• ✅ Phase 1: Core CLI commands (init, add, config, status, validate)
• ✅ Phase 2: Advanced commands (deploy, preview, update, env, cloudflare, doctor)
• ✅ Phase 5: MCP server (tools, resources, prompts)

Coming Soon:

• Phase 3: Templates, migration helpers, dry-run mode, config export/import
• Phase 4: CI/CD integration, testing setup, monitoring setup
