This guide provides a comprehensive reference architecture for building robust, production-grade applications on Replit. It covers best-practice project layouts, system-level configurations (like replit.nix), data layer strategies (PostgreSQL, KV, Object Storage), and secure deployment techniques. Use it when starting a new Replit project, optimizing existing codebases, or establishing enterprise-level architectural standards.

This guide details essential patterns for building fault-tolerant and highly available Replit applications. It covers handling cold starts, implementing graceful shutdowns (via SIGTERM), and crucially, migrating persistent application state from ephemeral local filesystems to robust external storage (like Replit KV or Object Storage). Essential for production-grade deployments.

This guide provides production-ready coding patterns for interacting with various built-in Replit services. It covers best practices for setting up singleton clients, implementing robust error handling, and creating type-safe wrappers for Key-Value Database, Object Storage, PostgreSQL, and Auth middleware. Ideal for developers building complex Replit integrations or establishing standardized data access layers.

A comprehensive guide detailing security best practices for building and deploying applications on the Replit platform. Learn how to properly manage sensitive data using Replit Secrets (AES-256 encryption), implement secure service-to-service authentication via REPL_IDENTITY tokens, validate custom headers, and prevent common vulnerabilities like hardcoded API keys and SQL injection. Essential for auditing and securing production environments.

This comprehensive guide outlines the necessary steps for major Replit environment upgrades and data migration. It covers updating Nix channels, upgrading runtimes (Node.js, Python), and migrating critical data from Replit KV databases to PostgreSQL or Object Storage. It also details switching between deployment types, ensuring a smooth and stable transition for production applications.

This guide provides comprehensive instruction on integrating with the full Replit ecosystem. Learn to monitor deployment lifecycles, set up external webhook receivers (e.g., GitHub, Stripe), build custom workspace extensions using React/TypeScript, and create complex automated workflows using Replit Agents. Essential for building scalable, event-driven applications on Replit.

Generate professional, single-file, horizontal-swipe HTML decks modeled after Replit Slides's visual system. Choose from eight distinct, comprehensive themes (e.g., helix, holm, atlas), each providing a complete visual identity (palette, typography, accents). Ideal for creating polished board reports, brand memos, product pitches, or long-form chapters with professional aesthetic consistency.

A single-file, horizontal-swiping presentation deck template inspired by Replit's modern aesthetic. This deck provides eight distinct, professionally designed themes (e.g., helix, world-mint, atlas). Use it for creating cohesive product or project pitches, ensuring perfect visual consistency by selecting and adhering to one theme’s full palette, font, and accent colors.
