It will launch a web portal at You need to use the code below in your NodeJS function to call the local DynamoDB: var AWS = require('aws-sdk') Įndpoint: ' }) Serverless DynamoDB Stream To start DynamoDB in local, run this command: sls dynamodb start Create, manage and execute migration scripts required to populate data in local DB – sls dynamodb create -n sls dynamodb execute -n.Starts DynamoDB locally with all the supported parameters (e.g., InMemory, sharedDb) – sls dynamodb start.Install DynamoDB locally – sls dynamodb install.Run the command below to install Serverless DynamoDB local plugin: npm install -save installed, add this plugin entry in the plugins array of the project JSON file: "plugins": Serverless DynamoDB local plugin is used to run DynamoDB in your local system for serverless flow. Let’s take a look at several plugins provided by serverless frameworks to manage several aspects of DynamoDB. To create this resource in AWS, you need to run the serverless deploy command in your serverless project. Resources: # CloudFormation template syntax In Serverless Framework, when you use AWS as a provider, all the resources are the other AWS services that are called by the AWS Lambda function mentioned in the service section. In this yml file, you need to configure DynamoDB in the resource section. Using Serverless Framework makes it easy to integrate DynamoDB and other serverless components.įor Serverless Framework, you need to write a serverless.yml file. It is built on top of CloudFormation scripts supported by AWS. Serverless Framework is an open-source project that supports building serverless applications on AWS and other clouds. A serverless chat application with AppSync and a DynamoDB database.A REST API triggered through AWS API Gateway, with Lambda functions and DynamoDB (a serverless backend for a web application).Using DynamoDB Streams as an event source for triggering Lambda functions.

Some of the use cases in which you can use DynamoDB include:

DynamoDB also provides easy integration with other AWS services, enabling a serverless architecture.

With the benefit of auto-scaling, pay-per-use, self-provisioning, and no server management, DynamoDB becomes the easy choice for many serverless applications. When you build a serverless architecture application, the key thing to remember is that all the components of this architecture should be able to scale based on the application’s needs. You can access these APIs using AWS SDK or AWS CLI. The reason for having this HTTP API is to provide the scalability behind the proxy where DynamoDB tables are stored in multiple hosts and replicas are created. The primary key is used to reference specific items in a table, or you can create your own indices and use the keys from those indices.ĭynamoDB exposes an HTTP API to access the tables for read and write. This primary key is either a single field or a combination of two fields: a partition key and a sort key. Each table has a primary key applicable to all the items within the table. Each item has a set of fields or attributes.

No other database claims throughput that high.ĭynamoDB stores its data in tables in the form of items. DynamoDB can handle 10 trillion requests per day. It is a key-value and document-based database that is fully managed, available in multiple regions, with built-in security, backup, and security. It is built to deliver single-digit millisecond performance at any scale - and is one of the favored database choices by serverless developers.
