Using it, you’re free to quickly provision a database to handle large amounts of diverse data.
What Is DynamoDB?
DynamoDB is a NoSQL database for storing data in a key-value format.
DynamoDB can handle large amounts of data across distributed infrastructure without compromising performance, durability, or reliability.
It offers a flexible model, letting you easily store and query data, whether its structured or unstructured.
you’re free to use DynamoDB as the database for various types of system.
Node.js provides wide support for external services including databases like AWS DynamoDB.
All you oughta access an AWS service from your Node app is the clientaws-sdkpackage for that service.
For instance, to access DynamoDB, you better install theclient-dynamodbpackage underaws-sdk.
You will do this when initializing the DynamoDB client.
In this file, instantiate a new AWS DynamoDB client using the following code:
Pretty simple!

TheEmailattribute here has typeSwhich means the field expects aStringas its value.
The three available attribute types areS,N, andB(String, Number, and Binary).
You need theKeySchemato define primary keys which help to find and organize items quickly.
You must add it to the KeySchema and specify itsKeyType(HASH).
The other available KeyType value isRANGEwhich is used for sort keys.
The third important parameter in the above code is theProvisionedThroughput.
Once youre sure the table is already active, you’re able to perform CRUD operations on it.
The following are some code examples that show you how to write and read data from theCustomertable.
