CalcMaker is an online form builder, with a focus around creating results real-time in browser, (think like a custom order form, mortgage calculators, etc..). Includes touch-enabled drag and drop interface. I was able to scratch an itch, while working with a client on a new idea.<p>Tech stack:<p>* Sapper/Svelte<p>* Tailwind<p>* Google/Firebase: Functions, Firestore, Auth<p>* Cloudflare: cdn, workers/kv<p>* Stripe: payments<p>The entire project (auth, database, payments) comes in normally under 200kb per page, even the heart of the application (the form editor) comes in @ 59kb. Nearly 100's across the board in Lighthouse.. Only a few accessibility issues with the homepage. I'm also experimenting with a mix of exporting sapper and using firebase functions for SSR. If no static file is found in Cloudflare, it falls back to the Firebase SSR / Sapper route.<p>Any questions or feedback let me know.<p>> Homepage: <a href="https://calcmaker.com/" rel="nofollow">https://calcmaker.com/</a><p>> No-signup Demo: <a href="https://calcmaker.com/playground/RxILjYhXs0JcHNPaYhTt" rel="nofollow">https://calcmaker.com/playground/RxILjYhXs0JcHNPaYhTt</a><p>> Example of the end form: <a href="https://calcmaker.com/-/RxILjYhXs0JcHNPaYhTt" rel="nofollow">https://calcmaker.com/-/RxILjYhXs0JcHNPaYhTt</a>
