template
| Property | Description |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| src | Selector to a <script template> element or a URL to an external template file. |
| data | Pass a component name to use the component's data as the dataset for the template context variables. |
| insert | Where to insert the rendered HTML using insertAdjacentHTML |
| type | To explicitly define the type of templating engine to use (handlebars, jade, mustache, nunjucks, html). |
Local context variables for the template are passed through the element's
dataset or
through the data property. If both are defined, they will be combined.
template-set
| Property | Description |
| ---------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| on | Event name to listen to before initializing template component. |
| data | What to set template.data to once event is fired. |
| src | What to set template.src to once event is fired. |
Vanilla HTML
If type is not defined and we are loading it from an external template, then
the component will render raw HTML.
Events
| Event | Description | |------------------|----------------------------------------| | templaterendered | Emitted when the template is rendered |
Script Tag Type
If loading from a script tag, it must have the type attribute defined. The
component will try to infer it from the script tag type attribute. It will
look within the attribute string for one of handlebars, jade, mustache,
nunjucks, or html:

Install via NPM:
npm install aframe-template-componentThen register and use.
require('aframe');
require('aframe-template-component');Troubleshooting
Note if using this within React, make sure the template is defined outside of React's root. React will treat the template as actual DOM rather than a string.
