| // 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. | |
