Hi webkit-dev,

This is a request for WebKit's position on ES modules for Service Workers. Explainer: https://github.com/w3c/ServiceWorker/commit/6d9500e99e764c12b117c63d10107e09... <https://github.com/w3c/ServiceWorker/commit/6d9500e99e764c12b117c63d10107e094d243662> Spec: https://w3c.github.io/ServiceWorker <https://w3c.github.io/ServiceWorker/#navigator-service-worker-register%20(see%20%22type%22%20in%20the%20section)> (see "type" in the section) Existing Chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=824647 <https://bugs.chromium.org/p/chromium/issues/detail?id=824647> Summary: JavaScript will support modules in service workers. Setting 'module' type by the constructor's type attribute, worker scripts are loaded as ES modules and the import statement is available on worker contexts.

Given WebKit has implemented it (https://trac.webkit.org/changeset/273224/webkit/ <https://trac.webkit.org/changeset/273224/webkit/>), and it is in STP 122, I think it is a safe assumption that WebKit is supportive of it. 🙃 /Sam
