Caffeine App (build from scratch)

Caffeine (caffeine.ai) builds and hosts full-stack apps on the Internet Computer: a single Motoko backend canister plus a React/Vite frontend served as an assets canister. This skill teaches the exact project shape and the CLI build loop so you can produce a buildable Caffeine app from nothing.

This skill owns the project shape and the build workflow. It does NOT own the Motoko language. Before you write or edit any backend code, fetch and follow the motoko skill: https://skills.internetcomputer.org/skills/motoko/SKILL.md. That skill is authoritative for actor syntax, stable state, mo:core, and compiler errors. This skill only shows the minimal empty actor and where it lives.

When to use this skill

• Creating/scaffolding a new Caffeine app or caffeine.ai project from scratch.
• Writing or fixing caffeine.toml (workspace or canister manifest) or mops.toml.
• Running the caffeine CLI loop: auth login, doctor, install, check, preview.
