Bundle report

[firelizzard18]

I would like to be able to generate a report from esbuild showing what files were bundled and how much each file contributed to the final bundled size. For example, if I have some main.js file that imports is-buffer, I'd like to see something like:

  out/main.js                        123b
  ├ src/main.js                      12b
  └ node_modules/is-buffer/index.js  23b

metafile

Yes the metafile should have all of the information you need. You can use it to write some code that does what you want.

For anyone else trying to do this, the following (linux/mac) shell commands will output a list of " ":

cat meta.json | jq -r '.outputs."out/extension.js".inputs | to_entries[] | "\(.value.bytesInOutput)\t\(.key)"' | sort -k 1 -nr
