Meta tags​

Use 8th Wall <meta> tags to quickly load common renderers and packages to your cloud editor project.

Use the name attribute to specify whether you are loading a renderer or a package, and the content attribute to specify which renderer/package:

<meta name="8thwall:renderer" content="renderer:version">
<meta name="8thwall:package" content="@package.package">

Renderers​

You can use the <meta name="8thwall:renderer" ...> tag to load A-Frame, three.js or Babylon.js to your cloud editor project:

<meta name="8thwall:renderer" content="aframe:version">
<meta name="8thwall:renderer" content="threejs:version">
<meta name="8thwall:renderer" content="babylonjs:version">

aframe​

Only certain versions of A-Frame are supported via the <meta> tag. This is because 8th Wall uses a custom version of A-Frame that makes various improvements to better support AR.

  • 0.8.2
  • 0.9.0
  • 0.9.2
  • 1.0.3
  • 1.0.4
  • 1.1.0
  • 1.2.0
  • 1.3.0
  • 1.4.1
  • 1.5.0
Example​
<meta name="8thwall:renderer" content="aframe:1.5.0">

threejs​

All versions of three.js are supported via the <meta> tag.

Note that three.js 160+ requires the use of import maps instead of a <meta> tag. See here for an example.

Example​
<meta name="8thwall:renderer" content="threejs:159">

Packages​

You can use the <meta name="8thwall:package" ...> tag to load common packages to your cloud editor project:

PackageContent Value
XRExtras@8thwall.xrextras
Landing Pages@8thwall.landing-page
Coaching Overlay@8thwall.coaching-overlay
Vue@vuejs.vue
HoloVideoObject@mrcs.holovideoobject
React@react.react
React DOM@react.react-dom
React Router DOM@react.react-router-dom
A-Frame Extras@aframe.aframe-extras
A-Frame Physics System@aframe.aframe-physics-system

Example​

<meta name="8thwall:package" content="@8thwall.xrextras">

All of the <meta> tags above evaluate to official CDN URLs. They will pull the latest supported version of the package. If you want to use a specific version, use a <script> tag instead.

Loading Specific Engine Chunks​

To minimize the end-user’s download size, you can selectively load only the necessary engine features using the methods below.

Cloud Editor​

You can specify which chunks to preload by adding the following meta tag to head.html.

  • Accepted chunks: 'slam', 'hand', 'face'.
<meta name="8thwall:preloadChunks" content="slam,hand,face" />

Self Hosted​

Alternatively, you can define the required chunks by adding the following script tag:

  • Accepted chunks are 'slam', 'hand', 'face'.
<script> window._XR8Chunks = ['slam'] </script>
