API
Fingerprint
Fingerprints output files for cache busting. Rewrites the references to the resources and renames the corresponding compilation assets.
Enable this plugin for the emit
phase.
Fingerprinting uses a checksum of the file content to generate a unique name for the file, references to the resource are renamed and the corresponding output file is renamed.
Because this plugin is enabled during the emit
phase you can be certain
that the generated checksums match the actual checksums of the referenced
files as the files have been optimized and sealed.

Fingerprint
new Fingerprint(context, options)
Create a Fingerprint plugin.
The rules
option is an array of regular expression resource patterns.
When no id
function is specified the default implementation will
generate a checksum of the resource file content. When no name
function
is given it generates a name prepending a period and the generated id
before the file extension.
The signature for an id
function is:
id(file, content)
It should return a unique identifier for the file.
The signature for a name
function is:
name(file, id)
It should return the new name of the file based on the supplied id
.
You may change the checksum algorithm using the algorithm
option but
it is recommended you use the default.
context
Object the processing context.options
Object the plugin options.
Options
rules
Array list of resource matching rules.algorithm
String=sha512 checksum algorithm.id
Function generate fingerprint id.name
Function generate new resource file name.
Throws
Error
if no resource graph is available.
.sources
Fingerprint.prototype.sources(file, context)
Inspects the rules assigned to this plugin and finds matching resources.
For each matched resource call the id
function to generate a unique
identifier for the resource followed by the name
function to generate a
new name for the resource.
Once the resource name has been allocated references to the resource are renamed and compilation asset output paths are renamed.
file
Object the current file.context
Object the processing context.
Throws
Error
if a resource could not be found in the graph.
