Using KYVE in your application
Initiating a node
import KYVE from "@kyve/logic";
const node = new KYVE();
Node configuration
KYVE requires two custom functions. One which fetches the data from your data source and one which validates this data. You can then simply add these two functions into the KYVE instance.
Specifying an upload function
To pass data into KYVE, simply call subscriber.next()
:
const myDataFetcher = async (subscriber) => {
// use your custom logic here
const data = ...
subscriber.next({ data });
}
You can also optionally add custom tags to your transactions:
const myDataFetcher = async (subscriber) => {
// use your custom logic here
const data = ...
const tags = [...]
subscriber.next({ data, tags });
}
Specifying a validation function
const myDataValidator = async (subscriber) => {
// fetch the data uploaded onto Arweave
const fetchedData = ...
const arweaveTxId = ...
// validate the data with your custom logic
const isValid = ...
// pass the result into KYVE
subscriber.next({ valid: isValid, id: arweaveTxId });
}
Giving the node your functions
import KYVE from "@kyve/logic";
const node = new KYVE(myDataFetcher, myDataValidator);
Pool configuration
Next you need to set up the pool. You can create a new pool here. After you have created the pool, insert its name and your arweave keyfile into the node config:
import KYVE from "@kyve/logic";
const pool = "demo-pool";
const jwk = ...
const node = new KYVE(myDataFetcher, myDataValidator, { pool, jwk });
Running your node
To run your node, simply call the .run()
function:
import KYVE from "@kyve/logic";
const pool = "demo-pool";
const jwk = ...
const node = new KYVE(myDataFetcher, myDataValidator, { pool, jwk });
(async () => {
await node.run();
})();
