Can't Use InvokeStore with module set to commonjs in TSConfig

[svozza]

I created a simple lambda with the following code:

import { InvokeStore } from '@aws/lambda-invoke-store';

export const handler = async (event: unknown) => {
    const invokeStore = await InvokeStore.getInstanceAsync();
    invokeStore.set('key', 'value');
}

My TS config is as folllows:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "commonjs",
    "moduleResolution": "node",
    "outDir": "./dist",
    "rootDir": "./src",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}

When I try to build with tsc, I get this error:

> invoke-store-cjs-issue@1.0.0 build
> tsc

src/index.ts:1:29 - error TS7016: Could not find a declaration file for module '@aws/lambda-invoke-store'. '/Users/svozza/git/github.com/svozza/invoke-store-cjs-issue/node_modules/@aws/lambda-invoke-store/dist-cjs/invoke-store.js' implicitly has an 'any' type.
  There are types at '/Users/svozza/git/github.com/svozza/invoke-store-cjs-issue/node_modules/@aws/lambda-invoke-store/dist-types/invoke-store.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.

1 import { InvokeStore } from '@aws/lambda-invoke-store';
                              ~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error in src/index.ts:1

If I change the compiler options to this, it works:

{
  "compilerOptions": {
    // ...
    "module": "node16",
    "moduleResolution": "node15",
    // ...
  },
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}

I have created a repo with a minimal reproduction here: https://github.com/svozza/invoke-store-cjs-issue.

Hi @maxday, any chance you could help here?

Thanks for reaching out, checking now

Thanks a lot for the reproducer, it really helps. I was able to reproduce the issue.
By adding : "types": "./dist-types/invoke-store.d.ts" in this package.json seems to solve your issue.
Can you confirm that after adding this, your error is gone too?
Thanks

Yes, this fixes the issue in my repo and in Powertools.
