/**
|
||
|
|
* A `ManifestTransform` function can be used to modify the modify the `url` or
|
||
|
|
* `revision` properties of some or all of the
|
||
|
|
* {@link workbox-build.ManifestEntry} in the manifest.
|
||
|
|
*
|
||
|
|
* Deleting the `revision` property of an entry will cause
|
||
|
|
* the corresponding `url` to be precached without cache-busting parameters
|
||
|
|
* applied, which is to say, it implies that the URL itself contains
|
||
|
|
* proper versioning info. If the `revision` property is present, it must be
|
||
|
|
* set to a string.
|
||
|
|
*
|
||
|
|
* @example A transformation that prepended the origin of a CDN for any
|
||
|
|
* URL starting with '/assets/' could be implemented as:
|
||
|
|
*
|
||
|
|
* const cdnTransform = async (manifestEntries) => {
|
||
|
|
* const manifest = manifestEntries.map(entry => {
|
||
|
|
* const cdnOrigin = 'https://example.com';
|
||
|
|
* if (entry.url.startsWith('/assets/')) {
|
||
|
|
* entry.url = cdnOrigin + entry.url;
|
||
|
|
* }
|
||
|
|
* return entry;
|
||
|
|
* });
|
||
|
|
* return {manifest, warnings: []};
|
||
|
|
* };
|
||
|
|
*
|
||
|
|
* @example A transformation that nulls the revision field when the
|
||
|
|
* URL contains an 8-character hash surrounded by '.', indicating that it
|
||
|
|
* already contains revision information:
|
||
|
|
*
|
||
|
|
* const removeRevisionTransform = async (manifestEntries) => {
|
||
|
|
* const manifest = manifestEntries.map(entry => {
|
||
|
|
* const hashRegExp = /\.\w{8}\./;
|
||
|
|
* if (entry.url.match(hashRegExp)) {
|
||
|
|
* entry.revision = null;
|
||
|
|
* }
|
||
|
|
* return entry;
|
||
|
|
* });
|
||
|
|
* return {manifest, warnings: []};
|
||
|
|
* };
|
||
|
|
*
|
||
|
|
* @callback ManifestTransform
|
||
|
|
* @param {Array<workbox-build.ManifestEntry>} manifestEntries The full
|
||
|
|
* array of entries, prior to the current transformation.
|
||
|
|
* @param {Object} [compilation] When used in the webpack plugins, this param
|
||
|
|
* will be set to the current `compilation`.
|
||
|
|
* @return {Promise<workbox-build.ManifestTransformResult>}
|
||
|
|
* The array of entries with the transformation applied, and optionally, any
|
||
|
|
* warnings that should be reported back to the build tool.
