Installing elemental-chat in the nix-shell

Technical Discussion RSM Technical Discussion!!
#1

Hi,

today I have read this blog post https://blog.holochain.org/elemental-chat-is-live/.
Is it possible to install the elemental-chat in the nix-shell itself and not on a holoport?

I followed the installation guide in https://github.com/holochain/elemental-chat

The commands:
git clone https://github.com/holochain/elemental-chat && cd ./elemental-chat
CARGO_TARGET_DIR=target cargo build --release --target wasm32-unknown-unknown
dna-util -c elemental-chat.dna.workdir

worked fine.

The ‘npm intall’ command found one vulnerability.

I tried to fix it with the mentioned ‘npm audit fix’ command.

With the ‘npm test’ command I tried to test it unfortunately it also failed.

As mentioned in this pull request I have also tried it with this command in between.

Has someone managed to get this working?

Yes, I was able to. I think the main issue here is holochain versions, the nix shell you are in has a different version that the elemental chat is compiled with. This will change once nix files are added to the repo, in the meanwhile you can try to compile holochain from the core repository with the hash with which elemental chat was compiled: https://github.com/holochain/elemental-chat/blob/develop/zomes/chat/Cargo.toml.

Thank you for your input.

Your linked file says:

...
[dependencies]

hdk3 = { git = "https://github.com/holochain/holochain.git", rev = "91d08f6574b2de41f5fcd27c23abfceeb54912a5" }
...

I looked up the syntax this says that the github branch of the holochain repository with the branch hash of “91d08f6574b2de41f5fcd27c23abfceeb54912a5” was used to compile the elemental-chat. Am I right?

Now for me the question was which branch has this hash.
I looked up all hashes for all branches unfortunately none of them matches.

I must miss something crucial here but I dont know what.

So that hash isn’t really associated with any branch. You need to just do git checkout HASH inside the core repository and then compile the source code.

Thank you very much I now got the “npm test” command working.

Do you maybe know if the “elemental-chat-ui” is allready ported to the Holochain RSM?

Well it’s actually been built only for RSM. So yeah, I’ve been able to make it work, although beware of environment variables inside the js code and setting them in the package.json
