What is missing in Sapper when compared to Gatsbyjs for JAM stack?

[kaushalyap]

I hope someone create a checklist of what is missing in Sapper when compared Gatsbyjs for JAM stack in order to keep track of Sappers progress.

I agree. Something like gatsby (react) or Gridsome (vue) for svelte would make it really interesting. I like the idea of hooking up data with plugins (or building my own), a graphql layer, generate static html and adding dynamic content on top where needed. And if that dynamic part is precompiled without any runtime library. Well then Im in cloud heaven 😂

It sounds like the two of you are best placed to give an idea of what is missing! It could certainly be a good base for a roadmap of sorts for Sapper.

@andriijas Can you please create a checklist? I could fill in if something is missing.

just linking my project here https://github.com/sw-yx/ssg as well as https://github.com/sveltejs/sapper/pulls/nealalpert

[andriijas]

• Pre-rendered HTML
• Automatic Code Splitting
• Follows PRPL-pattern
• Smart link prefetching
• Progressive Images
• Plugin architecture
• "Bring your own data"
• Graphql layer

Merging #869 would be a great first step. It would turn a broken system into a working one.
This issue alone is stopping us from considering svelte/sapper for any future projects at the moment.

In addition to what @andriijas mentioned

• PWA support
• Authentication ex: authentication in gatsbyjs
• Security baked in, avoiding things like Gatsby Content Security Policy (CSP) gatsbyjs/gatsby#10890
• Themes ex: gatsbyjs themes
• Incremental builds

i know both well. i'd say a subset of gatsby plugins can be adapted with low pain to work with sapper. the rest are unfortunately too React specific. would need adapters, or a "react mode".

linking #1110 - when copying static files, also set a(ccess)time and m(odification)time for the files

@andriijas Sapper does automatic code splitting and link prefetch

Routify is alternative to sapper.

Does team any plans related to this? I hope they prioritize this.
