node.js – How would I update variables in node js using promises?
Currently I am making a database using json taking inspiration from quick.db. However have run into the problem that I cannot auto update variables that i use the db.get function with.
Code:
const DB = require("./DB.js");
const db = new DB();
(async function() {
await db.set("kuno", 0);
var kuno = await db.get("kuno");
await db.add("kuno", 1);
console.log(kuno);
})();
The thing about that code is it does work, and add one to the db key “kuno” however still returns 0, is there any way I can update the kuno variable whenever the key is modified in the DB? Not sure if promises are even required for this but I intend on making this rely on actual SQL later.
