indexedDBModel variable globally which contains Model and ModelConfig.
They can be extracted as following
const {
ModelConfig,
Model
} = indexedDBModel;
// or
const ModelConfig = indexedDBModel.ModelConfig;
const Model = indexedDBModel.Model;
class Rooms extends ModelConfig{
//@overrides default method
get config() {
return {
version: 1,
databaseName: 'myNewDatabase',
tableName: 'myNewTable',
primaryKey: {
name: 'id',
autoIncrement: false
},
initData: [],
structure: {
roomId: { unique: false, autoIncrement: true },
roomName: { unique: false, autoIncrement: false },
comments: { unique: false, autoIncrement: false }
}
};
}
