Bug: Idempotency Package has No Exports

[brianhyder]

Expected Behaviour

The Idempotency package exports the functions and classes necessary to utilize the idempotency package.

Current Behaviour

The idempotency package does not seem to export any of the functions/classes as the other packages do.

If you look at the package.json for the idempotency implementation, it specifies that lib/index.js is the main entry point. However, that file does not exist. When you look at the other packges (logging, metrics, etc) it has the same package.json configuration but the index file exists.

Code snippet

See the links above.

Steps to Reproduce

See the links above.

Possible Solution

Add the index.ts file to the idempotency package and export the necessary types and functions.

Hi @brianhyder thanks for opening the issue.

At the moment this is intentional as we hadn't gotten yet to the point of building the utility for npm.

We will prioritize this item as soon as #1474 is merged, which should happen sometime tomorrow or Monday at the latest.

Hi @brianhyder, I've started working on this but I will need a bit more time as I want to make sure the exports are as isolated as possible and avoid running into future issues. For context: customers should be able to import & build the project regardless of whether they use Middy or DynamoDB as persistence layer, and so we need to build the exports accordingly.

In the meantime, after running npm pack and installing the tarball into your project, you can import any of the files by referencing it directly, i.e.

import { makeFunctionIdempotent } from '@aws-lambda-powertools/idempotency/lib/makeFunctionIdempotent';
import { DynamoDBPersistenceLayer } from '@aws-lambda-powertools/idempotency/lib/persistence/DynamoDBPersistenceLayer';
import { IdempotencyConfig } from '@aws-lambda-powertools/idempotency/lib/IdempotencyConfig';

The solution is not optimal and will change in the coming days, however it'll allow you to start playing with the module.

Excellent. I really appreciate the reply and workaround.
