Beloved template to quickly start hacking in top of any substrate based chain with
@polkadot/api.
See package.json to see what's up 🔥🔥.
First install ts-node
npm i ts-node
then install all npm packages
npm install
Optionally, in order to verify that you can connect with our node, run:
npm run dev
To run console in interactive mode, run:
npx ts-node -i
Then, we import api dependencies and connect with our node by running:
import { ApiPromise, WsProvider } from "@polkadot/api";
const provider = new WsProvider("ws://109.235.70.27:9944");
const api = await ApiPromise.create({ provider });
After this, we are able to interact with the API via api variable.
Example api calls:
(await api.query.profile.profileCount()).toJSON()
Returns the number of profiles.
(await api.query.task.tasksOwned('5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY')).toJSON()
Returns the tasks owner by a specified address.
(await api.query.task.tasks.entries()).toString()
Returns all entries of Tasks
