Lite Vimeo Worker 👷

A Cloudflare Worker that looks for Vimeo embeds on a page, and replaces them with the Lite Vimeo Embed facade.

Why would you want to do this?

• It's better for performance 🚀
• It makes your page greener 🌏️

Better performance

Rather than loading the Vimeo player, and all the JavaScript that comes with it. This Worker replaces it with a facade. Vimeo's JS code gets downloaded when the user wants to use the player.

Better for the planet

By default the Vimeo player downloads just around 250kB of data when it is loaded on a page. Using this Worker can reduce the initial size of your page by about 200kB per video (about 0.050 grams of CO2).

Options

This Worker uses slightlyoff/lite-vimeo. You can adjust the script to use any of options available in that web component.

Try it out

You can test this worker locally using Wrangler.

1. Checkout the demo branch.
2. Run the wrangler dev command.
3. Open your browser and navigate the running local server.
4. Using an extension like ModHeader in Chrome, set a new Request header x-demo: <the URL you want to test>.
