Class: DemandBuilder

props/builder.DemandBuilder

Builds an object of properties and constraints from high-level models.

description The object represents a Demand object, which is later matched by the new Golem's market implementation against Offers coming from providers to find those providers who can satisfy the requestor's demand.

example

import dayjs from "dayjs"
import { props } from "yajsapi"
dayjs.extend(utc);
const { Activity, DemandBuilder, NodeInfo } = props;
let builder = new DemandBuilder();
builder.add(NodeInfo("testnet", "a node"));
let act = new yp.Activity();
act.expiration.value = dayjs().utc().unix() * 1000;
builder.add(act);
console.log(builder);
// Output:
// {'properties':
// {'golem.node.id.name': 'a node',
// 'golem.node.debug.subnet': 'testnet',
// 'golem.srv.comp.expiration': 1601655628772},
// 'constraints': []}
