Is there full support for Node.js ESM imports in all major browsers?

[erifystudio]

Hello MDN team 👋,

I’ve been following the evolution of JavaScript modules and noticed some differences when testing ECMAScript modules (ESM) imports across Chrome, Firefox, and Safari.

👉 My questions:
• Do all major browsers (including mobile versions) fully support dynamic imports and import.meta?
• Are there still known limitations with import maps?
• Could MDN update the compatibility tables to reflect the latest status?

I’ve checked the current MDN compatibility data but wasn’t sure if the tables reflect 2025 updates.

Thanks for clarifying and keeping the docs sharp 💎🔥

•	Supported in Chromium browsers (Chrome, Edge, Opera) and Safari 16.4+.
•	Still not enabled by default in Firefox (only behind a flag).

So today, you can rely on import() + import.meta everywhere, but import maps remain limited until Firefox fully ships support.

Hi @erifystudio 👋

Thanks for staring this discussion. I see can see that Firefox supports import maps, as seen on the compatibility table. There is however no support for multiple import maps on Firefox.

The compatibility data on the import maps page looks accurate to me, so I will close this discussion as it's not relevant.
