Slice Simulator Nuxt 3


I am trying to setup with Prismic 3 and Nuxt 3 version, and get this error:
We can’t connect to the simulator page

[Vue warn]: Unhandled error during execution of render function
  at <SliceSimulator state= { slices: { components: { image_push: [Object] } } } >
[nuxt] [request error] h is not a function
  at Proxy.render (./node_modules/@prismicio/slice-simulator-vue/dist/index.js:75:12)

and in slice machine client console I am getting this error:

Uncaught SyntaxError: 
The requested module '/_nuxt/node_modules/escape-html/index.js?v=c4e61d85' 
does not provide an export named 'default' 
(at http://localhost:3000/_nuxt/node_modules/@prismicio/helpers/dist/index.js?v=c4e61d85:4:8)

Hi Tadas,

Slice Machine does not yet support Nuxt 3, but the team is working on this :slight_smile:

I get this

Do you guys not why? I use node 16

Hi Victor,

Slice Machine does not yet support Nuxt 3, but the team is working on this :slight_smile:



Hi Phil,

is there any news on when Nuxt 3 will be fully supported now they are at RC4?
Or specific for the Slice Simulator and Slice Machine?
Or at least support for the vue-essential-slices?

We really don't want to start a new project now in Nuxt 2 (Vue 2) with prismic.


Hi Frank,

Welcome to the community!

So I don't have any hard dates on anything but here's what I know:

  • Vue 3 SDK: it's in beta and will be published as latest in July.
  • Nuxt 3 SDK: it's in alpha and will be published in beta next week. It supports everything and is as "prod ready" as Nuxt 3 is (RC-ish)
  • Slice Simulator SDK: SDK for Vue 3 is available under @prismicio/slice-simulator-vue3 and is "prod ready"
  • Slice Machine will have Vue 3 / Nuxt 3 support end of Summer.
  • vue-essential-slices is pretty much deprecated at this stage.

So basically:

  • The SDKs are ready.
  • Slice Machine support is under construction.
  • The docs are under construction.


Thank you for your quick and clear response! We are looking forward to the new releases, and will continue to use the Nuxt 3 packages. We do have something working now :slight_smile:

One question comes to mind: When vue-essential-slices will be deprecated will there be a new 'UI library kit' set of components for these standard UI elements, or will they not come back?

I can imagine the latter, as we already are looking into making these custom anyway. This because of we need to be in control of the full lay-out and interactivity of the slices.

Hey Frank,

I'm happy to help.

There are no plans to revive this library at the minute. Maybe in the future, but it's not in the pipeline.


Hey Phil,

is it possible to have Slice screenshots/preview on Nuxt 3 ?

I tried adding Slice Simulator page as per:

But still get config errors on step 2 (Update your Nuxt config) and step 3 (Create a page for Slice Simulator).

It should be yes, but I guess Slice Machine won't let you launch The Simulator because you don't have the required package installed (slice-simulator-vue I guess), because Slice Machine doesn't support Nuxt 3 yet. So unfortunately you'll have to wait until then to use them all together properly.

Hi Phil,

With the stable release of Nuxt 3 being announced for next week (16th November), please could you share an updated status and timeline for stable versions of the various Prismic related Nuxt 3 components, including Slice Machine support?

Hey @here,

I received the latest from Lucie in our team :slight_smile:

Prismix x Vue 3 x Nuxt 3 (Nov. 2022) SDK Vue 3

SDK Nuxt 3

  • In RC, like Nuxt 3, will be released as stable alongside Nuxt 3
  • Doc still on Nuxt 2, but technical references are available:

SDK Slice Simulator

Slice Machine

  • No official support for Nuxt 3 nor Vue 3 yet
  • It's possible to hack its way through, but it's an unpleasant process, and for Prismic-savvy users only, we won't assist with that for now.
  • There's no official ETA Slice Machine support for Nuxt 3 right now, but hopefully, early Q1 2023.

Hello! @Phil, Is there an ETA on when we'll be able to use slice machine with nuxt 3? You were hopeful for Q1 of this year, we are in Q2 already!

Also with the absence of slice machine, how can I create custom types and slices for my project?

We will have news about this topic soon, and we encourage all those interested in following us on socials to stay up to date. You can subscribe to our Meetup and check out our progress page What's new - Prismic. We post updates there regularly.

Also, whenever we release these changes, they will be included in the release notes of Slice Machine GitHub.

You can still use the Legacy Builder if you're not using Slice Machine @zoe_steve.
