What is the difference between @aws-sdk/client-ses and @aws-sdk/client-sesv2?

Question

AWS's SDK for JavaScript version 3 seems to have 2 different clients for Simple Email Service (SES).

I realized I have been using @aws-sdk/client-sesv2 but:

• The actual doc on their GitHub repos is really hard to understand (see v1 and v2)
• Nowhere in the Github example do they show an example of sending an email or why there are 2 versions
• I found this more useful documentation but they don't even mention v2?

Are we supposed to use v1 or v2? What are the differences between both?

Answer 1

After poking around, the AWS SDK for JavaScript seems to have two versions:

• Version 2 under @aws-sdk: https://www.npmjs.com/package/aws-sdk
• Version 3 under @aws-sdk/client-*: e.g., https://www.npmjs.com/package/@aws-sdk/client-ses

Version 2 of the SDK is meant to be entering maintenance mode in 2023.

Now that this first layer of confusion is cleared out, the AWS SES API also has 2 versions:

• SES API v1: https://docs.aws.amazon.com/cli/latest/reference/ses/index.html
• SES API v2: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/ses/index.html

So based on this investigation, I presume that the packages points to the different API versions.
