This repo holds the overlay injector script, that basically add facts onto videos. It is used by the browser extension, and can be integrated on any website freely.
You can check the live demo with various integrations or the production version used by the French channel Thinkerview on thinkerview.com
- Basic injection
- Dynamic configuration
- Autosizing
- Multiple videos on a single page
Just specify a config object in window.CaptainFactOverlayConfig
global key and import script. This is the way
you usually want to go as it is simple and allows you to load the script asynchronously without worrying about
waiting for it to be ready.
<!-- Overlay configuration, see details below -->
<script type="javascript">
window.CaptainFactOverlayConfig = { /* Config here */ }
</script>
<!-- Import CaptainFact main script -->
<script
src="https://embed.captainfact.io/captain-fact-overlay-injector.min.js"
async
/>
You can also import the library and instantiate it yourself:
<script src="https://embed.captainfact.io/captain-fact-overlay-injector.min.js" />
Then:
let injector = new window.CaptainFactOverlayInjector({
/* Config here */
})
(!) For now the overlay can only be injected to one video per page. It's not a small change to make, but we haven't done it yet.
window.CaptainFactOverlayConfig = {
injector: {
