Dynamode is a modeling tool for Amazon's DynamoDB. Its goal is to ease the use of DynamoDB without its quirks and emphasize DynamoDB advantages over other databases. Dynamode provides a straightforward, object-oriented class-based solution to model your data. It includes strongly typed classes and methods, query and scan builders, and much more.

Dynamode is highly influenced by other ORMs/ODMs, such as TypeORM, Dynamoose and Mongoose.

Examples

Example table definition:

type ExampleTableProps = {
  propPk: string;
  propSk: number;
  index: string;
};

const TABLE_NAME = 'example-table';

class ExampleTable extends Entity {
  @attribute.partitionKey.string()
  propPk: string;

  @attribute.sortKey.number()
  propSk: number;

  @attribute.lsi.sortKey.string({ indexName: 'LSI_NAME' })
  index: string;

  constructor(props: ExampleTableProps) {
    super();

    this.propPk = props.propPk;
    this.propSk = props.propSk;
    this.index = props.index;
  }
}

export const ExampleTableManager = new TableManager(ExampleTable, {
  tableName: TABLE_NAME,
  partitionKey: 'propPk',
  sortKey: 'propSk',
  indexes: {
    LSI_NAME: {
      sortKey: 'index',
    },
  },
});

await ExampleTableManager.create();

Example entity definition:

type ExampleEntityProps = ExampleTableProps & {
  attr: { [k: string]: number };
};

export class ExampleEntity extends ExampleTable {
  @attribute.object()
  attr: { [k: string]: number };

  constructor(props: ExampleEntityProps) {
    super(props);

    this.attr = props.attr;
  }
}

export const ExampleEntityManager = ExampleTableManager.entityManager(ExampleEntity);

await ExampleEntityManager.put(new ExampleEntityManager({ ... }));
