db.get()

const LevelDB = require("leveldb-easy");
const db = new LevelDB("./databaseName"); // do not write file extension (like .js, .sqlite, .json)

db.on("get", (data) => {
	/* data = {
		"key": "keyData",
		"isSuccessful": false // because keyData named data wasn't found.
	} */
});
db.get("keyData");

db.get(key)

Data	Type
key	String

return Boolean - String - Object (Array - Date - Plain Object), Number - undefined (like "test_1", 12, ["test_2"])

db.on("get", data)

Data	Type
"get"	String
data	Function - Arrow function

db.set()

const LevelDB = require("leveldb-easy");
const db = new LevelDB("./databaseName"); // do not write file extension (like .js, .sqlite, .json)

db.on("set", (data) => {
	/* data = {
		"key": "keyData",
		"value": {"value": "data"},
		"isSuccessful": true
	} */
});
db.set("keyData", {"value": "data"});

db.set(key, value)

Data	Type
key	String
value	Boolean - String - Object (Array - Date - Plain Object), Number

return Boolean (true)

db.on("set", data)

Data	Type
"set"	String
data	Function - Arrow function

db.has()

const LevelDB = require("leveldb-easy");
const db = new LevelDB("./databaseName"); // do not write file extension (like .js, .sqlite, .json)

db.has("keyData");

db.has(key)

Data	Type
key	String

return Boolean (true or false)

db.update()

const LevelDB = require("leveldb-easy");
const db = new LevelDB("./databaseName"); // do not write file extension (like .js, .sqlite, .json)

db.on("update", (data) => {
	/* data = {
		"key": "keyData",
		"fn": [Function] ((x => (x + 1))),
		"function": [Function] ((x => (x + 1))),
		"newValue": 85,
		"oldValue" 3,
		"isSuccessful": true // because keyData named data was found.
	} */
});
db.set("keyData", 3)
db.update("keyData", (x => (x + 82)));

db.update(key, data)

Data	Type
key	String
data	Function - Arrow function (i recommend this)

return Boolean (true)

db.on("update", data)

Data	Type
"update"	String
data	Function - Arrow function

db.delete()

const db = new LevelDB("./databaseName"); // do not write file extension (like .js, .sqlite, .json)

db.on("delete", (data) => {
	/* data = {
		"key": "keyData",
		"isSuccessful": false // because keyData named data wasn't found.
	} */
});
db.delete("keyData")

db.delete(key)
