feat(dev): a terminal host for prompts, tasks and notifications by danielroe · Pull Request #1488 · nuxt/cli

📚 Description

this is a really big issue with #1463 🤦

currently, prompts raised from inside the dev server don't survive the interactive TUI. for example, useScript() in a project without @nuxt/scripts causes this prompt:

❯ Do you want to install @nuxt/scripts package?
● Yes / ○ No

but at the moment the question is folded away into the logs and it's impossible to answer.

this PR fixes some of the known issues:

... and adds three primitives to help modules interact with the new UI:

primitive	with the TUI	without a host
`withTerminal(work)`	borrows the terminal	`work()` runs directly, as today
`startTask(label)`	renders on the summary line as `⠸ installing with pnpm · 4.2s`, and an outcome is printed as a notice + added to history	clack spinner, as today
`notify({ message })`	full text into history, with a notice on the status line keypress/retraction	consumer's own fallback

I'll follow-up with a feature in nuxt/kit that allows module authors to hook into these primitives

Median of 15 interleaved runs per command, one warmup discarded.

Module load cost

Counted with a module.registerHooks load hook, compile cache disabled. Counts every JS module actually evaluated on that code path (built-ins excluded, native addons excluded).

Install footprint and published tarball

Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

Metric	baseline v3.37.0	head v3.37.0	Delta
Direct dependencies of `@nuxt/cli`	21	21	0.0%
Packages in the installed tree (unique name@version)	34	34	0.0%
Unique package names	34	34	0.0%
Package directories on disk (cross-check)	28	28	0.0%
Installed `node_modules` on disk	2.33 MB	2.34 MB	+0.4%
Installed files	419	418	-0.2%
Install wall time (warm npm cache, median of 3)	523 ms	533 ms	+1.8%
Published tarball (packed)	270.1 kB	273.6 kB	+1.3%
Published tarball (unpacked)	937.0 kB	947.7 kB	+1.1%
Files in tarball	131	130	-0.8%

Interleaved runs on a shared runner: trust the deltas, not the absolute timings. The dev, restart and build suites run locally via pnpm bench:cli.

📝 Walkthrough

Walkthrough

The CLI adds a versioned terminal-host contract shared through globalThis. The development TUI suspends panel rendering during borrowed terminal work, serializes borrowers, tracks tasks, renders notifications, and handles teardown. Console prompts use serialized host access and skip non-interactive sessions. Spinner utilities report host tasks and retain Clack fallbacks. Captured terminal rewrites are consolidated into transient log events. Module commands use the shared spinner utility. Tests and capture fixtures cover these behaviors.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk:⚪ Minimal · up to 07a3f

This change adds terminal-host behavior for prompts, tasks, and notifications; no actionable merge-blocking risk remains, so it is merge-ready after normal checks and review.

- Around line 261-272: Update the event handling around DevEventLog.push so
transient is assigned only when the raw event is newly inserted, not when push
returns an existing structured event via `#attribute`. Track the insertion outcome
separately and leave transient undefined for merged events, preventing later
spinner frames from overwriting them.
In `@packages/nuxt-cli/src/utils/spinner.ts`:
- Around line 33-41: Update the task lifecycle around host.startTask and the
awaited fn callback so successful completion passes success, but a rejected fn
records failure via task.stop before rethrowing the original error; preserve the
existing update and done handling.
In `@packages/nuxt-cli/test/unit/dev-tui.spec.ts`:
- Around line 2266-2271: Update the dismissal test around notice.dismiss() to
inspect the latest painted frame rather than comparing permission Request counts
from cumulative settle() buffers. Assert that the final frame no longer contains
the dismissed notice, while preserving the existing await notice.dismissed
synchronization.
