Turbopack build feedback

[timneutkens]

Thread for posting feedback about next build --turbopack.

[masterkain]

when creating a standalone build and starting with just node server.js we are greeted by the message to start with --turbo but it mentions next start instead so user is unsure where to place that flag

why does turbopack --build report different output sizes?

with 15.3.0-canary.33 i am trying next build --turbopack in a fresh CNA project initialised with pnpm create next-app@canary --empty.

running pnpm build --turbopack i see:

Route (app)                                     Size  First Load JS    
┌ ○ /                                            0 B         111 kB
└ ○ /_not-found                                  0 B         111 kB
+ First Load JS shared by all                 112 kB
  └ chunks/node_modules__pnpm_3614e913._.js    77 kB
  ├ chunks/node_modules__pnpm_ba52a8a1._.js  23.3 kB
  └ other shared chunks (total)              11.7 kB

however, running pnpm build (without --turbopack) i see:

Route (app)                                 Size  First Load JS    
┌ ○ /                                      136 B         101 kB
└ ○ /_not-found                            975 B         102 kB

turbopack build does not correctly resolve fonts from next/font - #77861
