roblox-datastores

separate

Persist player data in Roblox with DataStoreService: GetDataStore, GetAsync/ SetAsync/UpdateAsync/IncrementAsync wrapped in pcall, load-on-join and save-on-leave plus BindToClose, retries, and OrderedDataStore leaderboards. Use when saving or loading persistent data in a Roblox experience — when the user mentions DataStore, DataStoreService, GetAsync, SetAsync, UpdateAsync, save player data, or leaderboards. For general Luau scripting use roblox-luau.

When to use

• Use to save/load player progress (coins, inventory, levels), build persistent
• Use when server code calls `DataStoreService`, `GetDataStore`, `GetAsync`,

When not to use

• general scripting
• services
• remotes
• client/server split
• high-frequency temporary state
• matchmaking
• per-round state
• engine-agnostic persistence theory
