AsyncDB

AsyncDB has the same API as DB, but all methods are async.

const { AsyncDB } = require("kasperdb");
const db = new AsyncDB({ filename: "database/example", extension: ".db" });

Save Data

await db.saveData("money", { username: "example", count: 0 });

Get Full Data

const data = await db.getData();
console.log(data.money.count);

Get Data by Key

const data = await db.getData("money");
console.log(data.count);

Event Handling

Works the same as DB:

db.on("getData", (e) => console.log(`Got key ${e.key} from ${e.filename}`));
db.on("saveData", (e) => console.log(`Saved key ${e.key} to ${e.filename}`));
