/**
|
||
|
|
* Replace the __BUILD_VERSION__ placeholder in the built sw.js with a
|
||
|
|
* deterministic version string : the short git SHA + the build timestamp.
|
||
|
|
*
|
||
|
|
* Why : the service worker uses CACHE_VERSION to namespace caches and
|
||
|
|
* prune stale ones at activate. If __BUILD_VERSION__ stays literal,
|
||
|
|
* every deploy ships the same `veza-platform-__BUILD_VERSION__` cache
|
||
|
|
* name and pre-existing browser caches never get invalidated.
|
||
|
|
*
|
||
|
|
* v1.0.9 W4 Day 16.
