Time for Hologram <> JavaScript Interop - What Would You Like to See?
It’s time to implement JavaScript interop for Hologram!
Eventually, there will be Hologram wrappers for most APIs, but sometimes we’ll need escape hatches - especially when working with legacy apps or integrating 3rd party libraries. Things like:
- Integrating charting libraries (Chart.js, D3, etc.)
- Using JavaScript-only APIs (Web APIs, browser-specific features)
- Calling into existing JavaScript codebases
- Leveraging the vast npm ecosystem
How would you envision a Hologram <> JavaScript interop API/DSL?
Some questions to spark discussion:
- Should it be declarative or imperative?
- How should data be marshaled between Elixir and JavaScript?
- What would the ideal developer experience look like?
- Are there specific JavaScript libraries you’re eager to use?
- How should errors be handled across the boundary?
I have some ideas brewing, but I don’t want to bias the discussion by sharing them upfront. I’m genuinely curious about your use cases and what would make the most sense from a developer ergonomics perspective.
Looking forward to hearing your thoughts!

If I want to use google maps I am not looking to avoid javascript, I want to use javascript in the most practical manner possible.
Hologram is about isomorphic solution to 80-90% of your app, then for the rest where I can use pre-built stuff that is supported by a profitable business I just want a very ergonomic way to do javascript.
I do not think Bart spending time re-implementing Javascript in elixir is a good use of his time for that

I’d prefer to avoid basing architectural decisions on polls though 
Not that I don’t like polls, but I’m trying to provoke a deeper discussion here and am more interested in understanding the deeper trade-offs for Hologram’s specific context.
I’m honestly on the fence here and looking for someone to convince me why one of these approaches is genuinely better than the others. I don’t really care if something is familiar - what I care about is the best DX in general. Sure, familiarity might be part of DX, but there are many other factors like ease of use and ease of maintenance.
