If you're using EcmaScript modules, you probably know the problem that you can't "just" import JSON files. To import and load a JSON file in an ES module, you have to do a "window.fetch dance" to request the file and parse it yourself. It's not great...

But there's hope! According to, JSON Modules are shipping in Chrome 91. I gave it a quick try, and surprisingly, the following JavaScript code does not work.

<script type="module">
  import data from "./data.json";

It throws the following exception in Chrome 91:

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "application/json". Strict MIME type checking is enforced for module scripts per HTML spec.

I didn't have a detailed look at the spec discussion about this topic, but apparently, the new syntax to import JSON Modules is the following. ๐Ÿ˜ฒ

import data from "./data.json" assert { type: "json" };


That's quite something, and I have to do some reading about it. But hey, anything that makes it easier to import JSON is more than welcome!

And when there's a solution in Chrome, it can't be long until it ships in Node.js because importing JSON files in Node ES modules is not great either. ๐Ÿ™ˆ

Edit: Axel Rauschmayer shared that JSON import are based on import assertions and you can read more about it on his blog.
