Fs Fixture

fs-fixture

Use fs-fixture for tests that need realistic files or directories on disk.

Reference

Read the local README before using less common options or APIs:

node_modules/.pnpm/fs-fixture@2.8.1/node_modules/fs-fixture/README.md

If the exact pnpm store path changes, locate it with:

fd -a README.md node_modules/.pnpm | rg "fs-fixture"

Default Pattern

Prefer await using so cleanup is automatic:

import { createFixture } from 'fs-fixture';

await using fixture = await createFixture({
	'projects/example/session.jsonl': '{}\n',
});

const filePath = fixture.getPath('projects/example/session.jsonl');

Notes

• Use object trees for small inline fixtures.
• Use template directory input when many tests share the same larger fixture shape.
• Use fixture.getPath(...) instead of manually joining against fixture.path.
• Use fixture.writeFile() or fixture.writeJson() when a test needs to build data incrementally.
• Use templateFilter when copying only part of a template directory.
