I have built an app template which uses Go html/template package to render html on the server. The app is enhanced using sprinkles of javascript(stimulusjs, svelte single file components) on the client, wherever needed.

1. template: https://github.com/adnaan/gomodest-template

2. template demo: https://gomodest-template.fly.dev/

3. SAAS starter kit using the template(wip): https://github.com/adnaan/gomodest-starter
