[Feature Request] speed up checkout dialog

[bitkarrot]

Hi! - Satspay is one my favorite Extensions, thank you much for writing it.

However, the number one end user complaint I get is how long it takes for the timed dialog box and QR code to load. On a fast network connection it is no problem, other times it can be very slow and delayed.

I only took a brief look at the code and i see there is a mempool.js that has to remote load, is this possible cause of the slow down? Is there some way to speed this up as an option?

Thanks in advance.

• The largest downloaded file is the bundle.
• @dni can we have a sort of bundle-light.min.js that only includes the logic required for public pages?

i feel like the biggest part is quasar and vue which is still needed, not quite sure if it will bring that down significantly.

but as bitkarrot suggested, i think the problem is mempool.js from a cdn, i noticed some cdns are not really reliable especially when your geolocation is very different from your lnbits server. that is what i would suggest. include it into static

From the screenshot one can see that:

• mempool.js - 2.76 s
• bundle.min.js - 11.49 s

Which one should we optimize?

@bitkarrot can you please share the browser network stats on your side please

On a second thought I think @dni is right. mempool.js should be served as an extension resource.

Does this mean it should go on core and be part of the bundle?

added in lnbits/satspay#23

@motorina0 this is what i see on a business network connection

320ms :D but mempool.js was cached
