target: node>12 supports import.meta.url but esbuild says is not available in the configured environment.

[SalvatorePreviti]

NodeJS > 12 supports natively import.meta.url but setting it as a target generates an empty meta.url.

Warning is "import.meta" is not available in the configured target environment and will be empty

Forcefully setting the target to "es2020" causes instead other 2020 syntax to fail in node 12, 13, 14 like, for example, null coalescing operators.

Solution: esbuild with target node>12 should use the native import.meta.url

Thanks for the report. I think this is just due to a typo in esbuild's compatibility table:

esbuild/scripts/compat-table.js

Line 154 in 150a018

node10_4: false, // From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import.meta

This should be true, not false. Will fix.
