Following the instructions on README leads to an error

[xrash]

The only thing I did was running npm install @galacticcouncil/sdk and then running this code:

// Import
const { ApiPromise, WsProvider } = require('@polkadot/api')
const { TradeRouter, PolkadotApiPoolService } = require('@galacticcouncil/sdk')

const main = async () => {

  // Initialize Polkadot API
  const wsProvider = new WsProvider('wss://rpc.basilisk.cloud');
  const api = await ApiPromise.create({ provider: wsProvider });

  // Initialize Trade Router
  const poolService = new PolkadotApiPoolService(api);
  const tradeRouter = new TradeRouter(poolService, { includeOnly: [PoolType.XYK] });

  // Do something
  const result = await tradeRouter.getAllAssets();
  console.log(result);

}

main()

I get the following error:

    throw err;

Yupp, same for me.

[nohaapav]

@Denstden & @xrash Wasm file is not bundled with cjs, only with esm module .. In order to use SDK in cjs (node) you have to include wasm file at project root

[JackSparrowYB]

@nohaapav how can we get access to the wasm file? Can you let me know the steps?

[nohaapav]

@nohaapav how can we get access to the wasm file? Can you let me know the steps?

I'll update doc regarding cjs usage this week.

[flipchan]

@nohaapav is this fixed? I get the same error

[nohaapav]

@flipchan Hey, it was never broken, you just have to include wasm at project root in case u using cjs .. Hopefully i can prepare some step by step doc this week ..

[honglewis]

@nohaapav There are four directories containing a file named 'hydra_dx_wasm_bg.wasm,' namely 'math-lbp/build,' 'math-omnipool/build,' 'math-stableswap/build,' and 'math-xyk/build.' To make my CJS project work correctly, which one of these should I copy to the project root directory?

[xabsolon]

When i copy the wasm file from the following directories: 'math-lbp/build,' 'math-omnipool/build,' 'math-stableswap/build,' and 'math-xyk/build.' It says O.pool_account_name is not a function.

[michaeldev5]

Any updates on the documentation regarding CJS usage? @nohaapav

[flipchan]

@nohaapav is this fixed? I get the same error

solved it, all good for me

[michaeldev5]

How did you solve it ?

[flipchan]

@michaeldev5 will publish the hydradx implemenation opensource soon, I'm using "@galacticcouncil/sdk": "^0.6.5", with a clean npm cache, works

[nohaapav]

Try to upgrade to 1.1.5 or latest .. It should work with commonjs out of the box.

[michaeldev5]

It works! Many thanks @nohaapav

[flipchan]

@michaeldev5 seems like yarn.lock plays a prank on the new version bumps, here is an opensource implementation that ppl can use a reference: https://github.com/search?q=repo%3AXcmSend%2Fapp%20hydra&type=code

I added support for the latest version of the sdk

@nohaapav it was really nice the upgrade to v2 docs, it made my life easier, thanks
