```console

> nx run twenty-shared:build  [existing outputs match the cache, left as is]


> nx run twenty-emails:build  [existing outputs match the cache, left as is]


> nx run twenty-server:typecheck

> tsc -b tsconfig.json --incremental


> nx run twenty-server:build

> rimraf dist

> nest build --path ./tsconfig.build.json


>  SWC  Running...
