decache

Delete a module from node.js' require.cache so you can freshly require it again.

Build Status codecov.io Code Climate maintainability Dependencies Status devDependencies Status contributions welcome HitCount

In node.js when you require() a module, node stores a cached version of the module, so that all subsequent calls to require() do not have to reload the module from the filesystem.

decache ( Delete Cache ) lets you delete modules from node.js require() cache this is useful when testing your modules/projects.

Why?

When testing our modules we often need to re-require the module being tested. This makes it easy.

What?

An easy way to delete a cached module.

How? (usage)

install

Install the module from npm:

npm install decache --save-dev

Use it in your code:

// require the decache module:
var decache = require('decache');
 
// require a module that you wrote"
var mymod = require('./mymodule.js');
 
// use your module the way you need to:
console.log(mymod.count()); // 0   (the initial state for our counter is zero)
console.log(mymod.incrementRunCount()); // 1
 
// delete the cached module:
decache('./mymodule.js');
 
//
mymod = require('./mymodule.js'); // fresh start
console.log(mymod.count()); // 0   (back to initial state ... zero)

Modules other than .js, like for example, .jsx, are supported as well.

Note that native modules with the .node extension are ignored from decaching because they behave unexpectedly when decached.
