this should be graphiql.js or else it will break all the unpkg implementations

[dimaMachina]

what do you mean by it will break all the unpkg implementations?

/dist/index.umd.js === /graphql.js
/dist/index.umd.js === /graphql.min.js

[acao]

this is fine as long as it's serving the unminified umd version

[dimaMachina]

I made to use umd build only on CI, and you can see that all tests pass

locally I replace umd import

graphiql/packages/graphiql/index.html

Lines 26 to 37 in ad75cda

	<!--vite-replace-start-->
	<script
	crossorigin
	src="https://unpkg.com/react@18/umd/react.production.min.js"

	></script>
	<script src="/dist/index.umd.js"></script>
	<link href="/dist/style.css" rel="stylesheet" />
	<!--vite-replace-end-->

with src/cdn.ts

graphiql/packages/graphiql/vite.config.mts

Lines 102 to 111 in ad75cda

	const htmlForVite = /* HTML */ `

this looks good so far, but we still need graphiql.min.js and graphiql.js as the UMD versions or it will break all the many unpkg/jsdelivr implementations, just do a github code search and you'll see thousands. the benefits of consistent naming here are much less important than this pivotal backwards compatibility for our majority of users.

exports don't work with jsdelivr/unpkg unfortunately, we must publish to npm with these exact files

[dimaMachina]

this is for backward compatibility since I added exports field

I added prepublishOnly with the exact files

graphiql/packages/graphiql/package.json

Line 48 in ad75cda

"prepublishOnly": "cp dist/index.umd.js graphiql.js && cp dist/index.umd.js.map graphiql.js.map && cp dist/index.umd.js graphiql.min.js && cp dist/index.umd.js.map graphiql.min.js.map && cp dist/style.css graphiql.css && cp dist/style.css graphiql.min.css",
