ESM support?

[TessavWalstijn]

Hi recently I have come across some warnings in a Vite ESM project to resolve node modules to the browser.
However due to the following packages only being available in CJS it errors and breaks the build.

• crypto-browserify > Rebuild to TS or ESM ???
• timers-browserify > Rebuild to TS or ESM ???
• stream-browserify > Rebuild to TS or ESM ???
• stream-http > Rebuild to TS or ESM ???
• util > Rebuild to TS or ESM ???

NOTE: I haven't looked in to other packages yet since those are currently not in use by me.

There is one build in TS what could be configured to create an ESM build:

• buffer > Should be able to build for ESM as well with it being a TS

This package comes from substack but they result in a 404

• https-browserify > Repo

My questions are:

• Will browserify support ESM?
  This will make the difference if I will start creating PR's on existing packages to update them to support ESM
  Or create my own versions (potentially in an open github org browserify-ts or browserify-esm)
• If not - is it ok to use the "browserify" name in an other org for the ts / esm version of the packages?

A similar discussion looks like this one discussions/22 but I perceive it as inactive.

“support ESM” is the wrong phrasing; vite’s messaging here is just incorrect. CJS modules can be imported into ESM just fine.

Please don’t attempt to change the format of any package you’re not a maintainer on; that’s just not an appropriate task for a non-maintainer unless a maintainer has explicitly indicated it would be welcome.

The proper solution here is to configure vite to accept CJS properly, just like node and every other bundler does.
