SQLib

SQLib is the easiest way to store data for all your minecraft needs! A simple sql wrapper made with a focus on minecraft use cases.

Important Note:

This library is not a full-fledged sql wrapper, and does not provide full access to many sql features. The main focus of this library is to provide an easy and simple way to store data in your mods. If you are looking for a more advanced database I recommend taking a look at something like Nitrite.

Config

The mod generates a config on first time start that allows you to configure the database used by all mods relying on sqlib. The default database is a sqlite database running in the sqlib directory.

Datatypes

The datatypes can be accessed via JavaTpes, MinecraftTypes or the AdventureTypes classes. I tend to add support for new types as I run into them in my projects. If you would like one added, pleade make an issue!

Standard	Minecraft	Adventure
Byte	Vec3i	Key
Byte[]	BlockPos	Component
Bool	ChunkPos
Short	Text
Int	Identifier
Float	Sound
Double	Json
Long	NbtElement
String
Char
Date
Color
UUID
URI
URL

You can also add your own custom types as seen here:

Setup

In your build.gradle include:

repositories {
    maven { url "https://api.modrinth.com/maven" }
}

dependencies {
  modImplementation("maven.modrinth:sqlib:3.2.2")
}

Developer Usage

This example uses the built-in database managed by sqlib. for 99% of mods, using the built-in database is good, however further down are examples for custom database management.

// Do not call SQLib.getDatabase() in a early mod initializer. Doing so will likely crash your mod.
// Calling in or after the regular mod initializer is ok.
Database db = SQLib.getDatabase();

DataStore store = db.dataStore("myModId", "userdata");
        
DataContainer playerData = store.createDataContainer();
playerData.put(JavaTypes.STRING, "username", "CoolGuy123");
playerData.put(MinecraftTypes.BLOCKPOS, "home", new BlockPos(304, 62, 37));
playerData.put(MinecraftTypes.NBT, "nbt", new NbtCompound());

System.out.println(playerdata.get(JavaTypes.STRING, "username"));
System.out.println(playerdata.get(MinecraftTypes.BLOCKPOS, "home"));
System.out.println(playerdata.get(MinecraftTypes.NBT, "nbt"));

Custom Database Management

Postgres db = new Postgres("name", "192.168.1.69", "3306", "cooluser", "radman");
// OR
MySQL db = new MySQL("name", "192.168.1.69", "3306", "cooluser", "radman");
// OR
SQLite db = new SQLite("name", "some/dir");

Transaction Support

This approach will bach sql commands into one command for faster read/writes of large amounts of data.

DataStore store = db.dataStore("modId", "userdata");

DataContainer playerData = table.createDataContainer();
playerData.transaction().put("username", "CoolGuy123").put("home", new BlockPos(304, 62, 37).commit();

Custom Types

You can add a custom type by following the implentations in JavaTypes, MinecraftTypes and AdventureTypes. Then you can use it like any other native SQLib type.

// The SQLPrimitive is the base type to serialize to, and the two function lambdas are to serialize and deserialize from it
public static final SQLibType<JsonElement> JSON = new SQLibType<>(SQLPrimitive.STRING, JsonElement::toString, JsonParser::parseString);

// You can also extend a type like this:
public static final SQLibType<Identifier> IDENTIFIER = new SQLibType<>(SQLPrimitive.STRING, Identifier::toString, Identifier::tryParse);
public static final SQLibType<SoundEvent> SOUND = new SQLibType<>(IDENTIFIER, SoundEvent::getId, SoundEvent::of);
