Type error: QLDB is not a constructor

[Salmandabbakuti]

Hello @Lepozepo
I set up this module for my project and when I tried to run this example snippet for querying ledger, it shoots me with below error:

Type error: QLDB is not a constructor

are sure QLDB is a constructor? or am I missing something?

[Lepozepo]

Hmm, it should just work with import QLDB from 'qldb'. It's definitely the default export in the package. What configuration are you using to run it?

Thanks for your reply @Lepozepo
I've been using below command to run since it consists es6 imports, I modified my app.js to app.mjs and run like this.

node --experimental-modules app.mjs

Is this the problem?

[Lepozepo]

@Salmandabbakuti ah, that's probably it. So the src of the package is built with babel but when you run npm install qldb you're installing a set of prebuilt versions of this package. I think using just node app.js should work but you'll need to make sure to import using the normal require statement as you would without using any kind of compiler.

@Lepozepo , I tried using require but it still it is throwing that QLDB is not a constructor. Any possible solution?

[Lepozepo]

@Salmandabbakuti what do you see when you console.log the variable that's getting imported?

@Lepozepo

@Salmandabbakuti ah! You had to do require().default awesome. Glad you were able to get it working :D thanks for the mention!
