support install without post-install

[hardfist]

It seems that esbuild relys post-install to download the real bin for arch-spec bin file, which cause some troubles

• npm7 problem
• not support offline install

I wonder whether is there better ways to handle this?

It seems library like esbuild-linux-64 is not a standalone esbuild library(which only contains bin file), which makes npm alias like esbuild: "npm:esbuild-linux-64" not working, which is suitable for offline install

I assume you're talking about npm/cli#2606. One idea for an alternative implementation of esbuild's installer is #789. Unfortunately that approach hits another npm bug: npm/cli#2707. Although that has been fixed, lots of people are probably still using that buggy version of npm. It may be impossible to have a way to install esbuild that never hits npm bugs because of the way npm's bugs overlap.

I agree that adding the JavaScript APIs to all of the individual platform-specific packages may mitigate this issue somewhat. It's not a complete solution, however.
