A session token is only required if you are using temporary security credentials. The endpoint is unncessary when running against production AWSĪWS session token to use. Ensure that DynamoDB are available in that region.ĪWS endpoint for the component to use. "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" Can be secretKeyRef to use a secret reference ID of the AWS account with appropriate permissions to SNS and SQS. In order to use DynamoDB as a Dapr state store, the table must have a primary key named key. It is recommended to use a secret store for the secrets as described here. The above example uses secrets as plain strings.

#Aws dynamodb client configuration js how to
That’s cool.īut if you want to go further, in my upcoming posts I’ll show you how to use the new command-style API that v3 brings and how you can use esbuild to bundle your Lambdas in super-fast time. Maybe you’re happy enough with the bundle savings you’ve got or you don’t like the greater verbosity of the new command-style API. You could probably stop here and call it a day. In this post, I’ve covered how to migrate to the AWS SDK v3 while staying close to the v2 API interfaces. Make sure to redeploy all your Lambdas and run all your tests to verify nothing has broken before merging any changes.īTW, if you want to get better at testing your serverless apps, you might be interested in the next run of my Serverless Testing Workshop ?. For now we suggest to use the AWS JS SDK V2. There is currently no ETA for the feature release. There is currently a feature request in place for Data Plane functionality, I will add you as a +1 to that request. Run tsc and ensure everything is now working.Īlso having a comprehensive test suite (unit, integration and E2E tests) allows you to deploy a large cross-cutting migration such as this with much more confidence. aws-sdk/client-dax does not currently support Data Plane operations, only Control Plane such as CreateCluster. TypeScript isn’t for everyone but it really helps with a migration such as this to find out where the breaking changes are.

In addition to this, several previously non-nullable fields in SDK types are now optional, and so your code should do null checks.Īlso ensure that you have "skipLibCheck": true in the compilerOptions of your tsconfig.json file. For example, the type EventBridge.PutEventsRequest now becomes PutEventsRequest with the following import statement: To reference the type used by a v2 client method call in a request or response, you typically needed to reference the parent client as the namespace. Example from the SDK docs:Ĭonst ) TypeScript type definition changes And when you’re building single-purpose Lambda functions, you only ever need to call one operation more often than not. This makes it easy for code bundler to use a technique called treeshaking to only import the code needed for a single client operation. This still means that you only need to import the code for the specific operation you’re going to call. The API design for v3 is still broadly equivalent to v2 but it also allows developers to invoke specific operations using a new command-style syntax via a generic send function.You only require (or import) the module for the specific service client you need, rather than importing the entire aws-sdk module.There are two main reasons why the new SDK enables you to deploy smaller bundle sizes: In this post, I’ll give you a step-by-step migration plan to switch an existing Lambda project to use v3 of the AWS SDK.

It means we can now get the best of both worlds - a small package size (and thus faster cold starts) and a fixed dependency version. So the news that the new modular v3 version of the SDK is now generally available is very welcome. However, I have been bitten in the past by a new SDK function that worked on my machine but not when deployed to Lambda, so prefer the certainty of having a fixed version to run my production code against and have always bundled the SDK, despite it adding to the package size. The larger a package is, the longer it will take for the Lambda service to load it into memory and thus the slower “cold starts” will be.īecause of this, many people don’t include the AWS SDK in their deployment artifact as there is a version of the SDK automatically available in the Lambda runtime environment. In my experience with writing Lambda functions, the AWS SDK is often the largest dependency and certainly the most commonly imported one in the apps that I build.
