fix(generate): warn when scaffolding outside a Veryfront project by kojiwakayama · Pull Request #3712 · veryfront/veryfront-code

kojiwakayama · 2026-08-14T16:18:21Z

Found while dogfooding the documented journeys against published v0.1.1237.

Problem

veryfront generate writes relative to the invocation directory with no project check,
so running it one level above the project (or in the wrong terminal tab) silently creates
a stray app/ tree and exits 0:

$ cd /tmp                       # no package.json, no veryfront config, not a project
$ veryfront generate page about
Veryfront (v0.1.1237)
  ● Created /tmp/app/about/page.tsx
EXIT=0

veryfront dev already detects this situation and reports it well:

! No route directories found; skipping discovery. Searched .veryfront/, app/, pages/ …

generate should not be quieter than dev about the same condition.

Change

Warn when no project marker is present (veryfront.config.*, or a manifest that depends
on veryfront), then scaffold anyway. Warning rather than failing keeps it non-breaking —
bootstrapping a not-yet-configured directory still works.

$ veryfront generate page about
  ! /tmp/… does not look like a Veryfront project; scaffolding here anyway.
    Run this from your project root, or create one with "npm create veryfront".
  ● Created /tmp/…/app/about/page.tsx

Tests

Two tests in generate.integration.test.ts: warns in a bare temp dir (fails on main),
and stays quiet inside a real project (passes before and after, so the detection cannot
regress into warning on every run).

Verified by driving the real CLI in both a bare directory and a real project.
cli/commands/generate/ — 4 passed, 0 failed.

Note

While investigating I briefly thought generate rejected its own documented --help
examples. That was my shell harness, not the CLI — zsh does not word-split unquoted
expansions, so it passed "page about" as a single argument. generate is fine. Worth
recording only because the resulting error text (Invalid arguments) gives no hint that
the problem is argument count.

Summary by CodeRabbit

New Features
- Added automatic project detection before generation.
- Supports recognized configuration files and package manifests, including commented JSONC files and legacy configurations.
- Generation continues when run outside a recognized project, with a warning displayed.
Bug Fixes
- Generation remains quiet inside recognized projects.
- Warnings avoid exposing full directory paths.

`veryfront generate` writes relative to the invocation directory with no project check, so running it one level above the project (or in the wrong terminal tab) silently created a stray `app/` tree and exited 0: $ cd /tmp && veryfront generate page about ● Created /tmp/app/about/page.tsx `veryfront dev` already detects and reports this situation. Match it: warn when no project marker (veryfront.config.*, or a manifest depending on veryfront) is present, then scaffold anyway so bootstrapping a not-yet- configured directory keeps working. Found while dogfooding the documented journeys against published v0.1.1237.

Walkthrough

The generate command detects Veryfront project markers and warns when generation runs outside an apparent project. Generation continues after the warning. Integration tests cover project and non-project directories.

Changes

Generate project detection

Layer / File(s)	Summary
Project detection and generation warning `cli/commands/generate/command.ts`, `cli/commands/generate/generate.integration.test.ts`	The command checks known configuration files and manifest entries, including JSONC manifests. It warns in non-project directories while continuing to scaffold files. Integration tests verify detection, warning output, path redaction, and quiet behavior inside a Veryfront project.

Use the CLI import boundary.

Both CLI files add #veryfront/* imports. The CLI rules require #cli/* imports or relative imports inside cli/.

cli/commands/generate/generate.integration.test.ts#L5-L13: Replace the new #veryfront/* imports with approved CLI exports or local test adapters.

As per coding guidelines: “cli/**/*.ts: Use #cli/* or relative imports inside the CLI.”

…ests Three review findings, all confirmed against the code before changing anything: 1. The warning printed `projectDir`, an absolute machine path. AGENTS.md forbids local absolute paths in user-facing output. The directory is where the user already is, so the message names no path at all now. 2. `veryfront.config.json` was not a real marker — it appeared only in this file. The name the CLI config loader actually reads is the legacy `veryfront.json` (cli/shared/config.ts), so a project identified only by that file was warned about incorrectly. Swapped. 3. `deno.json` and `deno.jsonc` were parsed with strict `JSON.parse`, so a manifest using the comments and trailing commas Deno permits threw, hit the catch, and counted as no evidence — a false warning on a valid project. Now parsed with `parseExtensionManifest`, matching the JSONC grammar `src/extensions/discovery.ts` already applies to both filenames. Three regression tests added, one per finding. Not changed: the pre-existing `● Created <abs path>` line also prints an absolute path. It predates this PR and callers rely on it; worth a separate look rather than widening this change.
