a module for caching static http responses in memory
A module for caching static http responses in memory. It's available through npm
npm install cashier
Cashier allows you to cache in memory a result from a function and serve it using http.
It does so by wrapping a function into connect compatible middleware.
var cashier = require'cashier';var fs = require'fs';var serveFiles = cashiervar filename = '.'+url;fsreadFilefilenameif err return callbackerr;callbacknull data:buf watch:filename; // see more options below;;// let's mount it using expressvar express = require'express';var app = express;appuseserveFiles;applisten8080;
If you save the above example as
example.js and afterwards run it and visit
http://localhost:8080/example.js you should see the file being served.
Cashier is ensuring that we actually only read the file from disk once - any subsequent requests will be served from the cache.
Since we pass the
watch option Cashier will clear the cache if any of the files in the array changes.
dataa buffer or a string to be responded (a gzipped version will also be saved)
watcha file or array of files to be watched - the cache will clear if they are modified.
