ServiceWorkerの読み込みエラーでハマった

Posted at

ServiceWorkerを導入時にMIMEtypeのエラーが発生し、なんのこっちゃと思いましたが、.htaccessでAddTypeの指定漏れが原因だった模様。。。

エラー内容

Uncaught (in promise) DOMException: Failed to register a ServiceWorker: The script has an unsupported MIME type ('text/html').

.htaccessに追加した記述

AddType、AddCharsetに.JSを追加。

AddType application/javascript .js 
AddCharset utf-8 .js
