React Native Quick SQLite

The **fastest** SQLite implementation for react-native.

    Copy typeORM patch-package from example dir
    npm i react-native-quick-sqlite typeorm
    npx pod-install
    Enable decorators and configure babel
  

Quick SQLite uses JSI bindings, removes all the overhead of intercommunication between JavaScript code and C++ code, making CRUDing entities from SQLite super fast!

Big ❤️ to react-native-sqlite-storage and react-native-sqlite2 for paving the way, this library should offer a similar API.

GOTCHAS

• JSI bindings are not available when connected to the web browser debugger, from now on you should use Flipper.
• Your app will now include C++ files, this means you will need to install the NDK on your machine for android.
• TODO: Everything is saved on the application's home folder. I got lazy and ignore any passed path parameter, if you need this feel free to open a PR.
• TODO: The API is NOT 100% the same as sqlite-storage, sqlite-storage returns an item function on the query result, it takes an index number and returns an object, I simply return an array, because creating deeply nested structures from C++ is somewhat cumbersome.

Use TypeORM

The recommended way to use this package is to use TypeORM with patch-package. TypeORM already has a sqlite-storage driver. In the example project on the patch folder you can a find a patch for TypeORM, it basically just replaces all the react-native-sqlite-storage strings in TypeORM with react-native-quick-sqlite, and does a tiny change for the way it accesses the resulting rows from the SQL execution.

Follow the instructions to make TypeORM work with rn (enable decorators, configure babel, etc), then apply the patch via patch-package and you should be good to go.

If you are particularly masochistic you can hand write SQL and query the database directly yourself.

Low level API

interface ISQLite {
  open: (dbName: string) => any;
  close: (dbName: string) => any;
  executeSql: (
    dbName: string,
    query: string,
    params: any[] | undefined
  ) => {
    rows: any[];
    insertId?: number;
  };
}

// It is globally available in a variable called `sqlite`
sqlite.open({...options})

sqlite is a globally registered object, so you can directly call it from anywhere in your javascript. The methods throw when an execution error happens, so try ... catch them.
