Resolves #15977
Our
@tailwindcss/browser
build is intended to run inside a<script>
tag inside browsers. Because of how variable assignment within<script>
tags work, all variables that were defined within that script are currently assigned on the global namespace.This is especially troublesome as eslint uses
$
as a valid mangling character so importing the CDN build would now redefineglobalThis.$
which collides with many very popular JavaScript libraries.In order to avoid polluting the global namespace, this PR changes the build step to emit an IIFE (so all vars defined are scroped to the function closure instead of the global namespace).
