Bind to a function inside an object with export default

1

I was writing bindings to the chalk package using Deno npm specifiers.

In JS it is used like this:

import chalk from "npm:chalk@3";

console.log(chalk.blue("hello"));

This works perfectly.

In ReScript:

@module("npm:chalk@3") external blue: string => string = "blue"
blue("Hello")->Js.log

Compile to:

import * as Npmchalk3 from "npm:chalk@3";
console.log(Npmchalk3.blue("Hello"));

When I run deno run src/Demo.bs.mjs, I get the following error:

error: Uncaught TypeError: Npmchalk3.blue is not a function
console.log(Npmchalk3.blue("Hello"));
                      ^
    at file:///home/pedro/Desktop/rescript-with-deno/src/Demo.bs.mjs:5:23

I had to add @scope("default") to fix it.

@module("npm:chalk@3") @scope("default") external blue: string => string = "blue"

blue("Hello")->Js.log

import * as Npmchalk3 from "npm:chalk@3";

console.log(Npmchalk3.default.blue("Hello"));

Is there another way to do this? I didn’t find examples in the documentation.

I believe that’s the correct way. Perhaps you could send a PR to add that technique to the documentation?
