oclif + Ink CLI Patterns

\n
\n

Quick Guide: Use oclif for command routing, flag/arg parsing, and plugin architecture. Use Ink for React-based interactive terminal UIs with Flexbox layout. Combine both when commands need rich stateful interfaces. Always await waitUntilExit() when rendering Ink from oclif commands. Use this.log() instead of console.log to preserve JSON output mode.

CRITICAL: Before Using This Skill

\n
\n

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

\n
\n

(You MUST await waitUntilExit() after render() in oclif commands -- without it the process exits before the UI completes)

\n

(You MUST use this.log() / this.warn() / this.error() in commands -- console.log breaks --json mode and test capture)

\n

(You MUST wrap all text in <Text> components in Ink -- bare strings cause rendering errors)

\n

(You MUST use useEffect cleanup to cancel async operations -- Ink components unmount when the user presses Ctrl+C)

\n

Auto-detection: oclif, @oclif/core, @oclif/test, Ink, ink, @inkjs/ui, Command class, Flags, Args, useInput, useApp, useFocus, render(), waitUntilExit, terminal UI, CLI command, ink-testing-library

Decision Framework

\n
Building a CLI?\n|\n+-> Need multiple commands / subcommands?\n|   +-> YES -> oclif (multi-command mode)\n|   +-> NO  -> oclif (single-command mode) or plain Node.js\n|\n+-> Need interactive terminal UI?\n|   +-> Simple prompts (name, confirm)? -> Lightweight prompt library\n|   +-> Complex stateful UI (wizard, dashboard)? -> Ink\n|\n+-> Need both routing AND complex UI?\n    +-> YES -> oclif commands + Ink components\n    +-> NO  -> Use whichever fits the primary need\n

Command File Organization

\n
src/\n  commands/           # oclif command classes (.ts files)\n    init.ts\n    config/\n      get.ts          # mycli config get <key>\n      set.ts          # mycli config set <key> <value>\n  components/         # Ink React components (.tsx files)\n    wizard.tsx\n    progress.tsx\n  hooks/              # oclif lifecycle hooks\n    init.ts           # Runs before every command\n    postrun.ts        # Runs after every command\n  lib/                # Shared utilities\n

CRITICAL REMINDERS

\n
\n

All code must follow project conventions in CLAUDE.md (kebab-case, named exports, import ordering, import type, named constants)

\n
\n

(You MUST await waitUntilExit() after render() in oclif commands -- without it the process exits before the UI completes)

\n

(You MUST use this.log() / this.warn() / this.error() in commands -- console.log breaks --json mode and test capture)

\n

(You MUST wrap all text in <Text> components in Ink -- bare strings cause rendering errors)

\n

(You MUST use useEffect cleanup to cancel async operations -- Ink components unmount when the user presses Ctrl+C)

\n

Failure to follow these rules will cause silent process exits, broken JSON output, and terminal rendering crashes.
