Hc-happ-scaffold

Hi there

I tried to generate a happ with hc-happ-scaffold:

$ nix-shell https://nightly.holochain.love
$ hc-happ-scaffold user-happ-type-spec.json my-new-app

user-happ-type-spec.json:

{
  "types": {
        "user": {
          "description": "Create and manage users.",
          "sharing": "public",
          "definition": {
                "name": "string",
                "dob": "string",
                "icNumber": "string",
                "nationality": "string"
                }
        }
  }
}

it ends with this error:

cd dna-src && hc package

Any idea what to do?

Hum this is outdated tooling… Unfortunately hc-app-scaffold is deprecated. Where did you see docs or instructions to use it? We should probably delete those.

Is there any new similar tools?

#4

I’m curious about this too, if there was a command line util to just generate a default project structure.

#5

For modern tooling, take a look at, and git clone, the happ build tutorial.

git clone https://github.com/holochain/happ-build-tutorial.git my-project-folder
cd my-project-folder
rm -rf .git

Last line is to remove existing git data so that you can fresh run
git init
For your new project based on a good starter.

I’m sure this will come through sooner or later. For now, we can take our own shortcuts like the one I mentioned I guess

Thanks for answer. What a pity it is already deprecated…
I already tried happ-build-tutorial but it also ends with error…
