[dev-server-esbuild] Error after upgrading to esbuild 0.28 #3131

Problem

By default, Safari 11.1 is hardcoded here as the lowest supported versopn:

esbuild 0.28 marks destructuring as broken in Safari < 14.1 and cannot compile it down, so it fails with an error for any code that uses destructuring when the target includes safari11.1:

Transforming destructuring to the configured target environment ("chrome64", "edge79", "firefox67", "safari11.1") is not supported yet

Proposed solution

Update minimal Safari version to 14.1.

Note

In out project we had to set target to esnext as a workaround: vaadin/web-components#12101
