Setup Webflow

Install SSE in Webflow

In site-wide before-head, add your script references;

Make certain to adjust the src URLs to match your Netlify CDN.

<!-- Site Engine (SSE)
     https://engine.sygnal.com
--> 
<script 
  src="https://mysite.netlify.app/index.js"
  dev-src="http://127.0.0.1:3000/dist/index.js"
  ></script> 

Notes

The SSE <script> element must be placed once, site-wide, in the before-HEAD custom code area.

• src must point to the production CDN index.js

• test-src ( if specified ) must point to the test CDN index.js

• dev-src must point to your localhost served file. Typically this does not need to be changed unless e.g. you modify your :3000 port.

No CSS link references are needed, because SSE injects these automatically where they are needed.
