Is there a hello world or simple chat app for RSM?

@guillemcordoba

@harlan you can see this module, which is already updated and working: https://github.com/holochain-open-dev/file-storage/blob/main/dev-setup.md

You just checkout and run this

nix-shell .
cd ui
npm install
npm start

Let me know if you have any problems if you give it a go.

@guillemcordoba when I follow these instructions, plus modifying localhost:8888 -> [VM IP]:8888 in the start-ui script and also in ui/demo/index.html, the UI starts correctly but there seems to be nothing running on [VM IP]:8888. Screenshot:

Hm, thought I, perhaps I need to do as the readme suggests, and follow the instructions on the zome readme page.

But when I get to running the first of these commands:

hc s call register-dna --path zome/file_storage.dna.workdir/file-storage-test.dna
hc s call install-app <RESULT_HASH_OF_PREVIOUS_COMMAND>

There is no output, so not sure where to get the hash for the second command.

Here is my transcript:

[nix-shell:~/file-storage/zome]$ CARGO_TARGET=target cargo build --release --target wasm32-unknown-unknown

   Compiling file_storage v0.0.1 (/home/ubuntu/file-storage/zome/zomes/file_storage)
    Finished release [optimized] target(s) in 1m 54s

[nix-shell:~/file-storage/zome]$ hc s call register-dna --path zome/file_storage.dna.workdir/file-storage-test.dna

[nix-shell:~/file-storage/zome]$ echo $?
0

@guillemcordoba any ideas?

Multipass, great stuff! Followed your instructions and am back online again on macOS Mojave. Everything builds, thanks! ‍♂

@kristofer excellent, glad to hear it! I’m pretty happy with multipass, though I have to restart VMs regularly.

Curious what app(s) you got running? I’m still working on file-storage and elemental-chat, so far without full success.

I am looking to upgrade Key-value storage to hdk 0.0.1, and possibly also the sample app I made - Holochain / GraphQL Todo. But I’ll probably pause for a few days until Tryorama works again, see this post:

@guillemcordoba

So since hdk v0.0.100 and the removal of dna_utils the develop branch has been a bit “stuck” in that the tooling pack dnas was not ready yet. Today it is, but both the conductor-api repo and the tryorama repo are still having unmerged PRs.

[guillemcordoba]

Ohhh yes… So I think this is actually the same issue I found with the docker images. Holochain binds itself to 127.0.0.1, not to localhost, which makes it not accessible from the outside. I had to do a socat port forwarding to be able to call it, which you can see in the compository dockerfile.

[harlan]

Ah interesting, thanks. Maybe we could change it to optionally bind to 0.0.0.0, at least for dev usage. Just a musing… will look at socat too

[harlan]

@guillemcordoba that worked! Thanks for all your patient support.

For the record, I changed the ports from 8888 -> 8889 in the ui/package.json start-ui script and also in ui/demo/index.html , so it expects to hit holochain on port 8889, then did:

npm start &
socat tcp-l:8889,fork,reuseaddr tcp:127.0.0.1:8888 

– just copied from your example, no deep understanding of socat here, yet…
And now I am using the upload demo as expected.
