Quick.db is an open-source package meant to provide an easy way for beginners and people of all levels to access & store data in a low to medium volume environment. All data is stored persistently via either better-sqlite3, mysql2, pg or mongoose and comes way various other quality-of-life features.

• Persistent Storage - Data doesn't disappear through restarts
• Multiple Drivers - SQLite, MySQL, Postgres, Mongoose
• Works out of the box - No need to set up a database server, all the data is stored locally in the same project
• Beginner Friendly - Originally created for use in tutorials, the documentation is straightforward and jargon-free
• & more...

Installation

npm i quick.db

1. Install XCode
2. Run `npm i -g node-gyp` in terminal
3. Run `node-gyp --python /path/to/python` in terminal

If you're having troubles installing, please follow this troubleshooting guide. Windows users may need to do additional steps listed here.

Example With Sqlite (Default driver)

NOTE: In order to use this driver, install npm i better-sqlite3 separately.

const { QuickDB } = require("quick.db");
const db = new QuickDB(); // will make a json.sqlite in the root folder
// if you want to specify a path you can do so like this
// const db = new QuickDB({ filePath: "source/to/path/test.sqlite" });

(async () => {
    // Init the database, this is always needed!
    await db.init();

    // self calling async function just to get async
    // Setting an object in the database:
    await db.set("userInfo", { difficulty: "Easy" });
    // -> { difficulty: 'Easy' }

    // Getting an object from the database:
    await db.get("userInfo");
    // -> { difficulty: 'Easy' }

    // Getting an object property from the database:
    await db.get("userInfo.difficulty");
    // -> 'Easy'

    // Setting an object in the database:
    await db.set("userInfo", { difficulty: "Easy" });
    // -> { difficulty: 'Easy' }

    // Pushing an element to an array (that doesn't exist yet) in an object:
    await db.push("userInfo.items", "Sword");
    // -> { difficulty: 'Easy', items: ['Sword'] }

    // Adding to a number (that doesn't exist yet) in an object:
    await db.add("userInfo.balance", 500);
    // -> { difficulty: 'Easy', items: ['Sword'], balance: 500 }

    // Repeating previous examples:
    await db.push("userInfo.items", "Watch");
    // -> { difficulty: 'Easy', items: ['Sword', 'Watch'], balance: 500 }
    await db.add("userInfo.balance", 500);
    // -> { difficulty: 'Easy', items: ['Sword', 'Watch'], balance: 1000 }

    // Fetching individual properties
    await db.get("userInfo.balance"); // -> 1000
    await db.get("userInfo.items"); // ['Sword', 'Watch']
})();

Example With MySQLDriver

NOTE: In order to use this driver, install npm i mysql2 separately.

const { QuickDB } = require("quick.db");
const { MySQLDriver } = require("quick.db/MySQLDriver");
(async () => {
    const mysqlDriver = new MySQLDriver({
        host: "localhost",
        user: "me",
        password: "secret",
        database: "my_db",
    });

    const db = new QuickDB({ driver: mysqlDriver });
    await db.init(); // Connects and setup the database
    // Now you can use quick.db as normal

    await db.set("userInfo", { difficulty: "Easy" });
    // -> { difficulty: 'Easy' }
})();

Example With PostgresDriver

NOTE: In order to use this driver, install npm i pg separately.

const { QuickDB } = require("quick.db");
const { PostgresDriver } = require("quick.db/PostgresDriver");
(async () => {
    const postgresDriver = new PostgresDriver({
        host: "localhost",
        user: "me",
        password: "secret",
        database: "my_db",
    });

    const db = new QuickDB({ driver: postgresDriver });
    await db.init(); // Connects and setup the database
    // Now you can use quick.db as normal

    await db.set("userInfo", { difficulty: "Easy" });
    // -> { difficulty: 'Easy' }
})();

Example With MongoDriver

NOTE: In order to use this driver, install npm i mongoose separately.

const { QuickDB } = require("quick.db");
const { MongoDriver } = require("quick.db/MongoDriver");
(async () => {
    const mongoDriver = new MongoDriver("mongodb://localhost/quickdb");

    const db = new QuickDB({ driver: mongoDriver });
    await db.init(); // Connects and setup the database
    // Now you can use quick.db as normal

    await db.set("userInfo", { difficulty: "Easy" });
    // -> { difficulty: 'Easy' }

    await mongoDriver.close();
    // disconnect from the database
})();

Example With JSONDriver

NOTE: In order to use this driver, install npm i write-file-atomic separately.

const { QuickDB } = require("quick.db");
const { JSONDriver } = require("quick.db/JSONDriver");
const jsonDriver = new JSONDriver();
const db = new QuickDB({ driver: jsonDriver });

// Init the database, this is always needed!
await db.init();
await db.set("userInfo", { difficulty: "Easy" });

Example With MemoryDriver

Note: In-memory database is not persistent and is suitable for temporary caching.

const { QuickDB } = require("quick.db");
const { MemoryDriver } = require("quick.db/MemoryDriver");
const memoryDriver = new MemoryDriver();
const db = new QuickDB({ driver: memoryDriver });

// Init the database, this is always needed!
await db.init();
await db.set("userInfo", { difficulty: "Easy" });
