default

✓ import flac from 'flac'

✗ const flac = require('flac')

ESM import syntax; CJS require may work but ESM is recommended.

Flac

✓ import { Flac } from 'flac'

✗ import Flac from 'flac'

Named export for the Flac class; default export also exists.

find

✓ import { find } from 'flac'

✗ import find from 'flac'

Named export for the find function.

Basic usage of FLAC to create a cache instance, set and get a cached value.

import { Flac } from 'flac'; const cache = new Flac({ directory: './cache', maxAge: 3600 }); await cache.set('key', { data: 'value' }); const result = await cache.get('key'); console.log(result); // { data: 'value' }

Debug

Known issues

gotchaCache directory is not created automatically; must exist.

Ensure directory exists before creating Flac instance.

affects: >=0.0.0

deprecatedPackage is no longer maintained and has known vulnerabilities.

fix

Migrate to a maintained alternative like node-cache-manager.

affects: >=0.0.0

gotchaThe find method returns undefined if no file matches pattern.

fix

Check for undefined before using the result.

affects: >=0.0.0

gotchaFile caching is synchronous; blocks event loop.

fix

Use asynchronous alternatives or limit cache size.

affects: >=0.0.0

gotchamaxAge is in seconds but documented as milliseconds.

fix

Use seconds when setting maxAge.

affects: >=0.0.0

Errors

Common errors & fixes

Error: ENOENT: no such file or directory, open './cache/somefile.json'

Cache directory does not exist.

fix

Create the cache directory before initializing Flac: fs.mkdirSync('./cache', { recursive: true });

TypeError: Cannot read properties of undefined (reading 'data')

Cache get returns undefined for missing keys.

fix

Check if result is undefined before accessing properties: if (result) { ... }

Warning: flac is deprecated and has known vulnerabilities
