Extend Model

To extend Model class with type support we must provide Model's constuctor types.

import { Model, Schema } from "dynamoql";

    // This is a very simple example

class MyExtendedModel<A extends string, B, C> extends Model<A, B, C> {
  constructor(tableName: A, schema: Schema<B>, options: any) {
    super(tableName, schema, options);
  }

  async scanAll() {
    let ExclusiveStartKey;
    const Items = [];
    
    do {
      const res = await this.scan({}, { ExclusiveStartKey });

      ExclusiveStartKey = res.LastEvaluatedKey;
      Items.push(...res.Items);
    } while (ExclusiveStartKey);

    return Items;
  }
}
