_app.js build bundle size too big

Bug report

The _app.js build bundle size is too big

Describe the bug

I have looked through many issues for solutions and it seems that the team has repeatedly mentioned that next.js build bundle size is small. What I realised was that the _app.js was already 216 kb (with yellow indication, not green) when I have not added any additional code or library.

Adding a little more code or importing some libraries in a custom _app.js file will increase the bundle size until the indicator becomes red, meaning it is a unacceptable size?

To Reproduce

Just do npx create-next-app and yarn build

Expected behavior

Currently, _app.js bundle size is already 216 kb. Expected should be a much smaller value. I don’t know what should be the acceptable size, but of course, the smaller the better. Otherwise, it seems like next.js is really too bloated.

Hey guys I’d created a new project following your with redux thunk example and my _app.js file size became larger than 500kb.

Please shed some light.

just a suggestion… consider removing (or showing in different color) number for the total size of shared:
