Readme
Dedupes node modules as they are being required which works even when dependencies are linked via ln -s or npm link.
Loads foo.js
module only twice.
var foo1 = require('./pack1/common/dep-uno/foo');
var foo2 = require('./pack2/common/dep-uno/foo');
console.log(foo1.foo);
console.log(foo2.foo);
console.log(foo1 === foo2);
// =>
// loading foo from /Users/thlorenz/dev/projects/dynamic-dedupe/example/pack1/common/dep-uno
// loading foo from /Users/thlorenz/dev/projects/dynamic-dedupe/example/pack2/common/dep-uno
// foobiloo
// foobiloo
// false
Loads foo.js
module only once.
var dedupe = require('../');
dedupe.activate();
var foo1 = require('./pack1/dep-uno/foo');
var foo2 = require('./pack2/dep-uno/foo');
console.log(foo1.foo);
console.log(foo2.foo);
console.log(foo1 === foo2);
// =>
// loading foo from /Users/thlorenz/dev/projects/dynamic-dedupe/example/pack1/common/dep-uno
// foobiloo
// foobiloo
// true
Here instead of loading pack2/dep-uno/foo1.js
we will get a reference to the exports of pack1/dep-uno/foo
.js`
returned.
In some cases an app may be split into multiple parts that need to get the same instance of a common dependency (i.e.
Handlebars). This will work once you run npm dedupe
from the main package. However once you try linking to a
dependency via npm link
or just ln -s
it breaks.
This is where dynamic-dedupe comes in since it dedupes your modules as they are being required. Just make sure that you are using the exact same version of the packages whose modules you dedupe in order for this to work reliably.
npm install dynamic-dedupe
###dedupe.activate([ext, subdirs])
/**
* Activates deduping for files with the given extension.
*
* @name activate
* @function
* @param ext {String} (optional) extension for which to activate deduping (default: '.js')
* @param subdirs {Number} (optional) how many subdirs right above the module
* have to be the same in order for it to be considered identical (default: 2)
*
* Example: sudirs: 2 -- x/foo/bar/main.js === y/foo/bar/main.js
* x/boo/bar/main.js !== y/foo/bar/main.js
*/
###dedupe.deactivate([ext])
/**
* Deactivates deduping files with the given extension.
*
* @name deactivate
* @function
* @param ext {String} (optional) extension for which to activate deduping (default: '.js')
*/
###dedupe.reset()
/**
* Clears the registry that contains previously loaded modules.
*
* @name reset
* @function
