Ghost/ghost/signup-form

Embeddable Signup Form

Embed a Ghost signup form on any site.

Development

Pre-requisites

• Run yarn in Ghost monorepo root
• Run yarn in this directory

Running the development version

Run yarn dev to start the development server to test/develop the form standalone.

• This will generate a demo site on http://localhost:6173
• This will build and watch the production build and host it on http://localhost:6174/signup-form.min.js (different port!)

Using the UMD build during development

Vite by default only supports HRM with an ESM output. But when loading a script on a site as a ESM module (<script type="module" src="...">), you don't have access to document.currentScript inside the script, which is required to determine the location to inject the iframe. In development mode we use a workaround for this to make the ESM HMR work. But this workaroudn is not suitable for production.

To test the real production behaviour without this hack, you can use http://localhost:6173/preview.html. This HTML page will use http://localhost:6174/signup-form.min.js directly.
