feat(init): detect agent/CI environments and skip interactive prompts#1264
Conversation
Uses `std-env` v4's `isAgent`, `isCI`, and `hasTTY` to automatically detect when the CLI is run non-interactively (AI agents, CI pipelines, piped input) and apply sensible defaults instead of hanging on prompts. Adds two explicit flags for opt-in: - `--defaults` / `-y`: accept all defaults (like `npm init -y`) - `--no-interactive`: same, more explicit for scripting contexts When non-interactive mode is detected, the CLI: - Logs the reason (agent name, CI, no TTY, or flag) - Displays a full options reference — including all available templates fetched live — so agents can discover flags and re-run with custom settings - Auto-selects: template=minimal, dir=template's defaultDir, package manager=detected or npm, gitInit=false, modules=skipped - Fails fast (instead of hanging) when the target directory already exists, instructing the caller to pass `--force` All existing interactive behaviour is preserved when a TTY is present and none of the new flags are set. https://claude.ai/code/session_01LsDZBSg7peDmxh6QW33ag8
- Move detectCurrentPackageManager() before template load so package manager is known upfront - Compute all effective defaults (template, dir, pm, gitInit, install, modules) before any action is taken and display them together in a 'Proceeding with:' section at the bottom of the options note - Show all available templates with the default marked (← default) - Fix module examples to use @nuxt/content,@nuxt/ui,@nuxt/image - Remove scattered 'Auto-selected X' log lines — they are now covered by the single consolidated note - Simplify the non-interactive module-skip branch https://claude.ai/code/session_01LsDZBSg7peDmxh6QW33ag8
When running non-interactively (agent/CI/no-TTY) without a project directory, show the available options note then exit cleanly instead of proceeding with defaults. The agent reads the output, chooses the right flags, and re-runs with an explicit <dir>. nuxi init → shows options, exits (no project created) nuxi init my-app → creates my-app with defaults nuxi init my-app -t v3 → creates my-app with v3 template https://claude.ai/code/session_01LsDZBSg7peDmxh6QW33ag8

- Around line 130-135: The multiline boolean assignment for const
isNonInteractive (and the other multiline boolean expression further down) has
inconsistent indentation that breaks ESLint; reformat these expressions so
continuation lines are consistently indented — either align each boolean operand
under the first operand or wrap the RHS in parentheses and indent each
subsequent line one level (e.g., two spaces or one tab) so the operators (||)
and the operands line up consistently; update the lines that contain
isNonInteractive and the similar boolean block near the later expression to
match the project's multiline indentation style.

…ndition The original condition (!template || !dir) already covers every case where templates need to be loaded for prompts or the options note. Adding isNonInteractive caused an unnecessary network fetch when an agent provided both --template and dir (only to populate a template list in the note that wasn't needed). The 'Proceeding with:' section in the note still works correctly without it. https://claude.ai/code/session_01LsDZBSg7peDmxh6QW33ag8

Unreachable code: this branch can never execute.
In non-interactive mode, if ctx.args.dir is empty (the '' default), the code exits early at lines 230-233. Therefore, the isNonInteractive branch here for dir === '' is dead code since we'd never reach this point with an empty dir in non-interactive mode.
This doesn't break anything but adds confusion. Consider removing this branch or adjusting the early exit logic if you want non-interactive mode to auto-select a directory.
🧹 Proposed fix: Remove unreachable branch
let dir = ctx.args.dir
if (dir === '') {
const defaultDir = availableTemplates[templateName]?.defaultDir || 'nuxt-app'
- if (isNonInteractive) {
- dir = defaultDir
- }
- else {
- const result = await text({
- message: 'Where would you like to create your project?',
- placeholder: `./${defaultDir}`,
- defaultValue: defaultDir,
- })
-
- if (isCancel(result)) {
- cancel('Operation cancelled.')
- process.exit(1)
- }
-
- dir = result
- }
+ // In non-interactive mode, we exit early at line 230-233 if no dir provided
