TypedDB

TypedDB is a tiny client for DynamoDB.

Usage

Add configuration to use the client.

Configuration is an object to handle all the possible options to use DynamoDB

const configuration = {
    table: "TableName", 
    idPrefix: "Tbl", 
    options: { apiVersion: '2012-08-10' }
}

All entities need to extend Schema type to automatically create id, createdAt and updatedAt fields.

Use the client class to handle transaction operations.

The operations are already created:

• findById
• insert
• update
• query
• delete

Create an instance of client class to call operations.

const client = new Client(configuration)

Get the item by id

const item = await client.findById({id: "1233-345543-22334"})

Insert an item.

const item = await client.insert({
    name: "Test name", 
    lastName: "Test lastname"
})

The client object is going to create automatically id field when the insert transactions is done.

Update an item information.

Update method is going to return all the new values with the old values in a single object

const item = await client.update({
    {
    id: "1233-345543-22334",
    name: "Test name", 
    lastName: "Test lastname"
    }
})

Query items

TypedDB includes a minimal query dsl, it includes 5 basic operations:

• equal
• less
• greater
• and

• or

const queryExpression = new QueryBuilder().expression(greater('createdAt', '28812882')).build();
const items = await client.query(queryExpression)

Delete item by id

const item = await client.delete({id: "1233-345543-22334"})

Delete method is going to return the old values when the item is deleted.
