Can't import

[johnflux]

The npm package says to import as "@gradientai/nodejs-sdk" ( https://socket.dev/npm/package/@gradientai/nodejs-sdk ) which makes typescript happy, and I can autocomplete, but then when I do "npm start" gives the error:

"The requested module does not provide an export named "Gradient".

The example app on the other hand does:

import { Gradient } from "@gradientai/nodejs-sdk/src/gradient";

but this gives the error "Cannot find module or its corresponding type declarations"

If you look in the package.json in nodejs-sdk you can see the listed exports, and src/gradient is not listed in the exports.

Do you have a custom start command?
What version of the sdk is in your lock file?
What version of node are you using?
What version of typescript are you using?
What's your tsconfig & how are you compiling the target of your start command?
Or is the script a plain.js file that uses typescript just in the IDE for inferred types / jsdoc typing?

Do you have a custom start command?
I guess? It's doing: npm run build && node --enable-source-maps dist/start.js

What version of node are you using?
node v18.12.1

What version of typescript are you using?
5.0.4

What's your tsconfig & how are you compiling the target of your start command?

{
    "compilerOptions": {
        "target": "es2021",
        "module": "es2022",
        "lib": ["es2021"],
        "declaration": true,
        "sourceMap": true,
        "outDir": "./dist",
        "rootDir": "./src",
        "strict": false,
        "moduleResolution": "node",
        "esModuleInterop": true,
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true,
        "skipLibCheck": true,
        "forceConsistentCasingInFileNames": true,
        "resolveJsonModule": true
    },
    "exclude": ["dist", "node_modules", "tests"]
}

I've been playing with this, and it's definitely a CJS vs ESM problem. But I'm not sure why yet. When I try to launch my built package via node I get:

import { Gradient } from '@gradientai/nodejs-sdk';
         ^^^^^^^^
SyntaxError: Named export 'Gradient' not found. The requested module '@gradientai/nodejs-sdk' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@gradientai/nodejs-sdk';
const { Gradient } = pkg;

Node.js v18.12.1

So for some reason it's picking it up as CJS, despite I see that your package.json is attempting to support both.

Fwiw, I asked chatgpt, and it told me to simplify your package.json export section to just:

"exports": {
".": "./dist/cjs/index.js",
"./esm": "./dist/esm/index.js",
"./types": "./dist/cjs/index.d.ts",
"./types/esm": "./dist/esm/index.d.ts"
},

and this fixed it for me.

Thanks a lot @johnflux ! Supporting both is more complex than expected, I'll try to see if your fix handles both and release a patch!

Supporting both is more complex than expected

I feel you!!
Offtopic, but I am loving gradientai. Very much looking forward to playing with it some more.

Hey @johnflux , we updated the TS example with the newer version of the file, can I ask you if it works correctly now?

Here's an example I ran: https://gist.github.com/mhaligowski/0e8240ce0e45d3ee3dffc5f514a45c1c
