packages/custom-gatekeeper/vite.config.ts

1// Vite+ per-package settings. `vitest.config.ts` beside this file is vitest's own config (vitest
2// prefers it over this one); this file exists only to declare the `build` and `test` tasks that
3// `vp run` executes.
4//
5// Both are tasks rather than package.json scripts because each reads a path it also writes, and vp
6// declines to cache such a task: `tsc` emits into `dist/`, which automatic tracking otherwise counts
7// as an input of the same package, and every `vitest run` rewrites the scratch paths below and reads
8// them back on the next run. vp forbids a task and a script sharing a name, so the `build` and
9// `test` scripts are gone -- `vp run -F custom-gatekeeper <task>` is what replaces them.
10
11// This package's own `tsc` output. Package-relative, not workspace-wide: a sibling's `dist/` may be
12// a real input via its `exports`.
13const ownDist = { pattern: '!dist/**', base: 'package' } as const
14
15// Written and read back by every vitest run, so without these almost nothing caches. Workspace-wide
16// because tracking reaches past the package that owns the task -- a sibling's scratch files would
17// otherwise sit in this package's fingerprint. See
18// cloudflare-os/scripts/vitest-task-vite-config.ts for the full accounting of each path.
