loader-fs-cache

library1.0.3jsnpmunverified

A filesystem cache helper extracted from babel-loader's fs-cache module. Version 1.0.3 is the latest and only release. This package provides a simple promisified file system cache that stores compiled results on disk, checking timestamps and content hashes to invalidate stale entries. It is a standalone extraction from the babel-loader source. Not recommended for direct use; prefer babel-loader or other caching solutions like webpack's persistent cache.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import cache from 'loader-fs-cache'

✗ const cache = require('loader-fs-cache');

Package only provides a default export.

cache

✓ import cache from 'loader-fs-cache'

✗ import { cache } from 'loader-fs-cache';

Named import does not exist; only default.

type

✓ type Cache = typeof import('loader-fs-cache')

✗ import type Cache from 'loader-fs-cache';

No explicit type exports; use typeof.

Demonstrates basic usage: import, find cache directory, set up cache options, and check for cache hit/miss.

import cache from 'loader-fs-cache'; import findCacheDir from 'find-cache-dir'; import { join } from 'path'; const cacheDir = findCacheDir({ name: 'my-repo' }) ?? '.'; const src = 'const x = 1;'; const options = { directory: cacheDir, identifier: 'babel', config: { presets: ['@babel/preset-env'] }, }; cache(options).then((result) => { if (result && result.src === src) { console.log('Cache hit'); } else { console.log('Cache miss'); } });

Debug

Known issues

deprecatedThis package is no longer maintained. It was extracted from babel-loader and has been superseded by babel-loader's own caching or other solutions.

fix

Use babel-loader's built-in cache or implement your own caching with find-cache-dir and fs.

affects: >=0.0.0

gotchaThe cache key is generated from `identifier` and `config` but not from source hash. If source changes without different identifier/config, old cache may be returned.

fix

Ensure you include a hash of the source in the identifier or config to guarantee invalidation.

affects: >=1.0.0

gotchaThe package relies on `find-cache-dir` which may return `undefined` if no package root is found, causing errors.

fix

Provide a fallback directory when using `findCacheDir`.

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'find-cache-dir'

Missing peer dependency `find-cache-dir`.

fix

npm install find-cache-dir

TypeError: cache(...) is not a function

Using named import instead of default import.

fix

Use `import cache from 'loader-fs-cache'` instead of `import { cache } from 'loader-fs-cache'`.
