What needs to be documented once your changes are merged?

• entry: {} is now a support option for an build without configured entrypoint. e. g. when using only entrypoints generated by plugins.
• When loading things with script tags, the runtime will now try to find an existing script tag that matches the src or has a secific data-webpack attribute.
  • For chunk loadng data-webpack="chunk-[chunkId]", for script external data-webpack="[global]"
• When loadng things with script tags, the runtime will now remove the script tag once the script has been loaded.

New script external:

• The new script externalType will load a script tag and use a global afterwarts.
• Syntax: external: { xxx: ["http://example.com/script.js", "global", "property", "property"] } (properties are optional)
• Shortcut syntax: external: { xxx: "global@http://example.com/script.js" }
• Any url is allowed. Public path will not be added.
• Options like output.chunkLoadTimeout output.crossOriginLoading output.jsonpScriptType will apply to these scripts too.

Module Federation:

• The default for ModuleFederationPlugin.remoteType is now: ModuleFederationPlugin.library ? ModuleFederationPlugin.library.type : "script"
• The default for the ModuleFederationPlugin.library is now { type: "var", name: name }

@chenxsan Can we close it or something need more docs?

@evilebottnawi The Module Federation part is not documented yet. It's a kinda advanced topic, would be great if someone familiar with it can help document it. Also it's an old issue, things might have changed.
