Serve Static Cache is an Express middleware for writing responses to static files. Used in combination with the serve-static middleware or your web server's static file serving, it can dramatically improve the speed at which responses are served. It does so by automatically generating static files containing the response contents for any GET request made to your server.
npm install serve-static-cache
Like the serve-static middleware, Serve Static Cache expects a root directory to use as a target for generated files. In most cases, this will match the one you use for serving static files.
var path = require( 'path' );
var express = require( 'express' );
var cache = require( 'serve-static-cache' );
var server = express();
server.use( cache( { root: path.join( __dirname, '/public' ) } ) );By default, Serve Static Cache will never delete cached file. If instead you'd prefer for cached files to be deleted when first initialized, pass a clean parameter. If you also plan to serve non-cached file out of your public directory, you may want to serve a separate directory when used in combination with the clean option.
var path = require( 'path' );
var express = require( 'express' );
var cache = require( 'serve-static-cache' );
var server = express();
server.use( express.static( path.join( __dirname, '/public' ) );
server.use( express.static( path.join( __dirname, '/public-cache' ) );
server.use( cache( { root: path.join( __dirname, '/public-cache' ) } ) );The following options are made available:
| Type | String |
| Required | Yes |
The target directory for generated files.
| Type | Boolean |
| Required | No |
| Default | false |
Whether the target directory should be reset when the middleware initializes.
The following features are not yet available, but are planned for future versions.
- Setting time-to-live cache duration for files
- Exposing cache-busting options
