Trying to run

[libinysolutions]

First of all, great script. I'm trying to do a npm run but it's not working. I get the message below.

import { AMM } from '@oselezi/solana-volume-sdk';
         ^^^
SyntaxError: Named export 'AMM' not found. The requested module '@oselezi/solana-volume-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 '@oselezi/solana-volume-sdk';
const { AMM } = pkg;

Hi @libinysolutions ,

Thank you for reaching out and for your kind words about the script! I'm glad you're finding it useful.

I understand you're encountering the following error when running your script:

import { AMM } from '@oselezi/solana-volume-sdk';
         ^^^
SyntaxError: Named export 'AMM' not found. The requested module '@oselezi/solana-volume-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 '@oselezi/solana-volume-sdk';
const { AMM } = pkg;

This error occurs because the SDK is currently exported as a CommonJS module. When using ES module syntax (i.e., import statements), you might run into issues importing named exports from CommonJS modules.

Here's how you can fix the issue:

Your tsconfig.json can be like this:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "moduleResolution": "NodeNext",
    "esModuleInterop": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "skipLibCheck": true,
    "allowSyntheticDefaultImports": true
  }
}

And you have to include type: "module" in your package.json file.

instead of

import { AMM } from '@oselezi/solana-volume-sdk';

please try

import { createRequire } from 'module';
const require = createRequire(import.meta.url);

const SDK = require('@oselezi/solana-volume-sdk');
const { AMM } = SDK;

Let me know if you need further assistance or if you encounter any other issues.

@libinysolutions Please try to run it with tsx

npx tsx index.ts

You can check the example folder for the usecase.
