named chunks

NamedChunksPlugin.js

// All webpack chunks have an identifier that is written to both the chunk and
// the chunk manifest.
//
// By default, webpack uses "int" identifiers, where the identifiers are
// sequentially generated after chunks are ordered by OccurenceOrderPlugin.
//
// The result of this is that small code changes may cause chunks to be
// reordered, leading to a cascading change of chunk ids, and a large number of
// chunk rehashes that could have been avoided.
//
// This plugin assigns chunk identifers based on the chunk name, which should
// be both unique and stable, and reduce the number of chunk rehashes.
