This repository is meant to be a scaffolding starting point to build reusable holochain modules (zome & UI module).
This is what is has included:
- UI and Zome Instructions to use the module in a bigger app
- Github Actions automatic integration with building and testing
- Zome
- Basic sample code
- Integrated tests with tryorama
- Instructions to include the zome as a crate in any DNA
- UI
- Reusable CustomElements with
lit-element
- Automated demoing with
storybook
, also publishing togh-pages
- Automated testing with
web-test-runner
- Automated end-to-end testing with the holochain zome
- See open-wc for all the available tools and documentation
- Reusable CustomElements with
- Create a new repository from this template (you can use the
Use this template
button on the top of this page). - Look for all the
TODO
keyword to see the places that need to be changed. (NOTE: replacing it inside the files can easily be done with your IDE, and for renaming files & directories you can use this bash one-liner:new_name=YOUR_NEW_NAME_HERE find . -name "*todo_rename*" | while read line ; do mv $line $(echo $line | sed 's/todo_rename/$new_name/g') ; done
) - Remove this section of this README.md until this next line.
TODO: carefully change whatever needed in this README.
Small zome to create and see calendar events, in holochain RSM.
This module is designed to be included in other DNAs, assuming as little as possible from those. It is packaged as a holochain zome, and an npm package that offers native Web Components that can be used across browsers and frameworks.
See our storybook
.
- Create a new folder in the
zomes
of the consuming DNA, with the name you want to give to this zome in your DNA. - Add a new
Cargo.toml
in that folder. In its content, paste theCargo.toml
content from any zome. - Change the
name
properties of theCargo.toml
file to the name you want to give to this zome in your DNA. - Add this zome as a dependency in the
Cargo.toml
file:
[dependencies]
hc_zome_todo_rename = {git = "https://github.com/holochain-open-dev/todo_rename", package = "hc_zome_todo_rename"}
- Create a
src
folder besides theCargo.toml
with this content:
extern crate hc_zome_todo_rename;
- Add the zome into your
dna.yaml
file with the nametodo_rename
. - Compile the DNA with the usual
CARGO_TARGET=target cargo build --release --target wasm32-unknown-unknown
.
See the list of available elements here.
-
Install the module with
npm install "https://github.com/holochain-open-dev/todo_rename#ui-build"
. -
Import and define the the elements you want to include:
import ConductorApi from "@holochain/conductor-api";
import {
MyCalendar,
CalendarEventsService,
CALENDAR_EVENTS_SERVICE_CONTEXT,
} from "@holochain-open-dev/todo_rename";
import { ContextProviderElement } from "@holochain-open-dev/context";
async function setupCalendarEvents() {
const appWebsocket = await ConductorApi.AppWebsocket.connect(
"ws://localhost:8888"
);
const appInfo = await appWebsocket.appInfo({
installed_app_id: "test-app",
});
const cellId = appInfo.cell_data[0].cell_id;
const service = new CalendarEventsService(appWebsocket, cellId);
customElements.define("context-provider", ContextProviderElement);
const provider = document.getElementById("provider");
provider.name = CALENDAR_EVENTS_SERVICE_CONTEXT;
provider.value = service;
customElements.define("my-calendar", MyCalendar);
}
- Include the elements in your html:
<body>
<context-provider id="provider">
<my-calendar> </my-calendar>
</context-provider>
</body>
Take into account that at this point the elements already expect a holochain conductor running at ws://localhost:8888
.
