🎉 What's New?

Build Tools

• Adds a new navigationPreload config property (defaulting to false) to workbox-build's generateSW and generateSWString modes, which would also expose it to the wrappers like workbox-cli and workbox-webpack-plugin. [#1981]

workbox-core

• Adds workbox.core.cacheNames.prefix and workbox.core.cacheNames.suffix for accessing the current prefix and suffix used in generating cache names. [#2001]

• Adds a new cacheKeyWillBeUsed lifecycle callback. This allows developers to override the default cache key for reads or writes (or both). [#1990]

The interface for the callback looks like:

:::js
async function cacheKeyWillBeUsed({request, mode}) {
  // request is the default Request object that would otherwise be used as the cache key.
  // mode is either 'read' or 'write', depending on whether it's a read or a write.
  // Return either a string, or a Request whose url property will be used as the cache key.
  // Returning the original request will make this a no-op.
}

🐛 What's Fixed?

workbox-webpack-plugin

• Convert source to Buffer when getting asset's hash, improving compatibility with some webpack loaders [#1966].
• Added sorting before generating a hash in the precache manifest. [#1973]
