Generates a diff between two browserify-json-bundles. This is part of the browserify-diff toolchain.

Example

From:

{
	"version" : 1,
	"modules" : {
		"./foo" : ["console.log('foo');",{}],
		"./bar" : ["console.log('bar');",{}]
	},
	"entry" : ["./foo"]
}

To:

{
	"version" : 2,
	"modules" : {
		"./foo" : ["console.log('now I print something else');",{}],
		"./baz" : ["console.log('baz');",{}]
	},
	"entry" : ["./baz"]
}

Resulting diff:

{
	"from" : 1,
	"to" : 2,
	"modules" : {
		"./foo" : ["console.log('now I print something else');",{}],
		"./bar" : null,
		"./baz" : ["console.log('baz');",{}]
	},
	"entry" : ["./baz"]
}

Methods

var diff = require('browserify-json-bundle-diff');

create(from, to)

Generates a diff between two browserify-json-bundles. It will:

• Put the version of from as the value for the from key in the diff
• Put the version of to as the value for the to key in the diff
• Add any module in to that is not present in from to the modules hash
• Add any module in to that is not equal to the same module in from to the modules hash
• Add any module that is present in from but not in to to the modules hash with a value of null
• Adds the entry from to if it is not equal to the entry from from.

merge(first, second)

Merges two diffs together. It is required that the second diff is a direct successor of the first diff, that is first.to === second.from.
