URL: https://github.com/apache/superset/pull/37588#issuecomment-3828160333
## **Sequence Diagram**
The PR replaces Babel with SWC for transpilation, disables expensive dev
source maps, and enables webpack filesystem caching while increasing Node heap
size. The diagram shows the core developer-to-build flow changes that reduce
OOMs and speed up incremental builds.

participant Dev as Developer
participant Scripts as Package Scripts
participant Docusaurus as Docusaurus (webpack)
participant SWC as swc-loader
participant Cache as Webpack Filesystem Cache
Dev->>Scripts: yarn start / yarn start:quick
(NODE_OPTIONS=--max-old-space-size=8192)
Scripts->>Docusaurus: launch dev server (generate:all or skip)
Docusaurus->>SWC: Transpile superset-frontend files with swc-loader
(replaces babel)
Docusaurus->>Cache: Use filesystem cache for incremental rebuilds & HMR
Docusaurus-->>Dev: Serve site (no eval-source-map in dev, reduced memory
use)
```
