dynamodb-data-mapper-js | A schema-based data mapper for Amazon DynamoDB | AWS library

Using the mapper object and MyDomainObject class defined above, you can perform the following operations:. Creates (or overwrites) an item in the table. Retrieves an item from DynamoDB. NB: The promise returned by the mapper will be rejected with an ItemNotFoundException if the item sought is not found. Updates an item in the table. Removes an item from the table. Lists the items in a table or index. Finds a specific item (or range of items) in a table or index. The mapper also supports batch operations. Under the hood, the batch will automatically be split into chunks that fall within DynamoDB's limits (25 for batchPut and batchDelete, 100 for batchGet). The items can belong to any number of tables, and exponential backoff for unprocessed items is handled automatically. Creates (or overwrites) multiple items in the table. Fetches multiple items from the table. NB: Only items that exist in the table will be retrieved. If a key is not found, it will be omitted from the result. Removes multiple items from the table.
