parse-cache-control

library1.0.1jsnpmunverified

A lightweight, dependency-free function to parse HTTP Cache-Control headers, extracted from the hapi.js Wreck HTTP client. Version 1.0.1 is stable but unmaintained since 2016. Key differentiator: returns a simple object with parsed directives, no frills. Simpler than dedicated HTTP caching libraries, but limited to basic parsing.

Code

Verified usage

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

default

✓ import parseCacheControl from 'parse-cache-control'

✗ const { parseCacheControl } = require('parse-cache-control')

Package exports a single function as default export. No named exports.

default (CommonJS)

✓ const parseCacheControl = require('parse-cache-control')

CommonJS works fine; package does not provide ESM.

TypeScript usage

✓ // @ts-ignore import parseCacheControl from 'parse-cache-control';

✗ import parseCacheControl from 'parse-cache-control';

Package has no TypeScript types. You may need a declare module or skip type checking.

Demonstrates basic usage: parse a Cache-Control header string into an object of directives.

const parseCacheControl = require('parse-cache-control'); const header = 'public, max-age=31536000, s-maxage=86400'; const parsed = parseCacheControl(header); console.log(parsed); // Output: // { public: true, // 'max-age': '31536000', // 's-maxage': '86400' }

Debug

Known issues

deprecatedPackage is unmaintained since 2016. No updates or security patches.

fix

Consider using a maintained alternative like 'http-cache-semantics' or 'cache-control-parser'.

affects: *

gotchaBoolean directives (e.g., 'public', 'no-cache') return true; numeric directives return strings, not numbers.

fix

Parse numeric values manually, e.g., parseInt(parsed['max-age'], 10).

affects: <=1.0.1

gotchaInput header is case-sensitive? No, but directive names are normalized to lowercase. Spaces in directives may cause unexpected results.

fix

Trim input and remove extra spaces.

affects: *

gotchaNo support for quoted string values (e.g., private="set-cookie").

fix

Expect only simple token values.

affects: *

Errors

Common errors & fixes

TypeError: parseCacheControl is not a function

Using named import when package exports a default function.

fix

Use default import: import parseCacheControl from 'parse-cache-control'

Cannot find module 'parse-cache-control'

Package not installed or incorrectly required.

fix

Run: npm install parse-cache-control

parsed.max-age gives a string instead of number

Package returns all values as strings, even numeric ones.

fix

Convert to number: Number(parsed['max-age'])
