Getting Started
This package is a parser and builder for all Cache-Control directives. You can parse a
string with parse() and build a http ready header with
tokenize().
All needed documentation is available in form of TSDoc comments.
Usage
import { parse, CacheControl } from 'cache-parser';
const rawHeader = 'public, max-age=3600';
const {
public, // true
maxAge, // 3600
immutable // undefined
} = parse(rawHeader);
const cacheProperties: CacheControl = { public: true, maxAge: 3600 };
// ['public', 'max-age=3600']
const cacheTokens = tokenize(cacheProperties);
// 'public, max-age=3600'
const httpHeader = tokens.join(', ');
