Overview

Install

Usage

Import

import {
    Cell, DNA,
    AppEntryType,
} from '@whi/holochain-prototyping';

Basic

Example

import { AgentPubKey } from '@whi/holo-hash';

class PostEntry extends AppEntryType {
    static struct               = {
        "published_at": Number,
        "author": AgentPubKey,
        "message": String,
    };
}

const dna                       = new DNA([
    {
        "EntryTypes": [
            PostEntry,
        ],
        "LinkTypes": [
            "Post",
        ],
        "validation": (op) => {
	    // ...validation code
	},
    },
]);

const agent = new AgentPubKey( crypto.randomBytes(32) );

const cell = new Cell( agent, dna );

cell.run( 0, () => {
    const {
        agent_info,
        hash_entry,
        create_entry,
        create_link,
    } = HDK;

    const agent = agent_info().agent_initial_pubkey;
    const post = new EntryTypes.PostEntry({
        "published_at": Date.now(),
        "author": agent,
        "message": "Hello world",
    });

    const address = hash_entry( post );   // EntryHash
    const post_id = create_entry( post ); // ActionHash

    create_link( agent, post_id, LinkTypes.Post, tag );
});
