Configure Vite+ workflows

Inspect the installed vite-plus version, root and owning-package manifests and vite.config.ts files, build/pack.ts, relevant CI workflows, and the command's current clean-run behavior before editing. Use pnpm exec vp <command> --help and installed types when they differ from online documentation.

Read references/official-guide.md only for the sections that match the work: task graphs, cache diagnosis, GitHub Actions cache, Pack, or migration.

Workflow

1. Classify each operation: vp build for applications, vp pack for libraries, and vp run for orchestration and caching. Invoke a script or configured task as vp run <name>; bare vp <name> selects a built-in command.
2. Preserve build boundaries. Keep historically separate packaging workflows in separate Vite+ configs unless they are genuinely variants of one build. A named pack array supports vp pack --filter <name> within one workflow; a nested vite.config.ts supports an independent workflow via vp -C <dir> pack.
3. Define ordering in run.tasks, not in serial shell pipelines. Every configured task needs command and cannot duplicate a same-named package.json script. Use { task: 'build', from: ['dependencies', 'devDependencies'] } for declared direct workspace edges and package#task for synthetic edges such as generated CDN assets. -r selects workspace tasks; it does not replace missing task dependencies.
4. Let the graph expose independent work to Vite+'s scheduler. Do not lower concurrency to repair missing edges. Reserve --parallel, which ignores dependencies, for independent persistent tasks such as development servers.
5. Keep root scripts as thin selectors. Put package-specific commands, inputs, outputs, environment, and dependencies in the owning package's config.
6. Prove local cache stability before configuring cross-run cache. Only vp run uses Vite Task caching. Run the exact task twice and require the second run to hit. Prefer automatic tracking, then add cache.input, cache.output, cache.env, or cache.untrackedEnv only from observed misses. Avoid generators that rewrite unchanged inputs.
7. In GitHub Actions, install first, restore node_modules/.vite/task-cache, run the same vp run tasks used locally, and save only after success. Keep source and lockfile hashes out of the Actions cache key because Vite Task fingerprints task inputs.

Repository gotchas

• Reuse packaging defaults from build/pack.ts; keep package entries, platform, and exceptional plugins local.
• Top-level Vite resolve.alias and Pack's pack.alias serve different consumers. Do not assume one configures the other; share alias constants when both commands need identical mappings and test both paths.
• Vite+ loads a package config before it can schedule that package's dependencies. Config-time imports from private workspace packages must be available without relying on their built output.
• vp pack uses file-system cache tracking rather than vp build's cooperative Vite metadata. Diagnose its observed reads and writes before adding manual globs.

Example

Input: The sandbox build consumes normal workspace packages and generated HTML CDN files.

Output: A configured build task with declared workspace and generated-artifact dependencies.

build: {
  command: 'vp build',
  dependsOn: [
    { task: 'build', from: ['dependencies', 'devDependencies'] },
    '@videojs/html#build:cdn',
  ],
}

Validation

Run the narrow target from a clean output state, inspect vp run -v ordering, and run it immediately again to verify cache hits and restored outputs. Then run the affected package tests/build, pnpm typecheck when types or configs changed, and pnpm check:workspace. For CI changes, verify restore occurs after install, save uses the restore step's primary key, and logs show both an Actions cache restore and Vite Task cache hits.
