cannot use with deno

[oscar6echo]

I tried use pg-structure with deno which is meant to be node-compatible, and is most of the time I tried.
However I cannot seem to be able to use pgStructure.

Doing the recommended:

import pgStructure from "pg-structure";
const db = await pgStructure({ host: "host", database: "db", user: "u", password: "pass" }, { includeSchemas: ["public"] });

leads to this error:

It is not just an IDE error. It fails at runtime too.

I suspect some export does not work as expected...
I would be great if this could be fixed (?)

I'm not familiar with Deno. However, according to the error message, it seems directly realted to the importing of the "pg-structure".

import pgStructure from "pg-structure"; // This line seems to import wrong thing in Deno
const db = await pgStructure(...)

It may be specific to import mechanics of Deno.

Sorry, all my answer is speaculation, but hope it will guide you to debug the problem.

Thx for the swift reply!
And btw, congrats for the neat, very useful and well documented lib 👍

Yes, I agree with you that for some reason deno import does not work as expected for node packages in this case.
But it does not most cases I have ran into. For example, I can use 'pg-structure' via pg-tables-to-jsonschema, which exports a class the "usual way" there. The only difference I see is that 'pg-structure' does "more complex" exports, with default and named exports together there. But I see no reason why it should not work 🤔

I'll raise it to Deno team...

This is not an error in Deno. The same error occurs when you try to import this module in Node in ESM mode. The types are wrong in the npm package, see https://arethetypeswrong.github.io/?p=pg-structure%407.15.3 .

// main.mjs
import pgStructure from "pg-structure";
console.log(pgStructure());

$ node main.mjs
file:///project/main.mjs:2
console.log(pgStructure());
            ^

TypeError: pgStructure is not a function

Node.js v23.11.0

The easiest fix would be to ship a proper ESM variant in the npm package instead of only commonjs code.
