Tree Shakable Helpers

InterchainJS provides tree shakable helper functions to optimize your application's bundle size. These helpers follow a factory pattern that allows modern JavaScript bundlers to eliminate unused code through tree shaking. These helpers improve modularity and optimize performance by allowing you to import only the functionality you need. Tree shakable tutorial video: https://youtu.be/3dRm9HEklMo

How Tree Shakable Helpers Work

Each helper function is individually exported using a create* prefix (e.g., getAllBalances). Each customized hook is individually exported using a use* prefix (e.g., useGetBalance) This pattern enables:

1. Bundle Size Optimization: Only the functions you import and use are included in your final bundle
2. Lazy Initialization: Helper functions are only constructed when explicitly called
3. Customizable Configuration: Each helper can be configured with specific parameters

For example, query helpers are functions that return other functions, constructed with specific parameters:

// Import only what you need
import { getAllBalances } from "@interchainjs/cosmos/bank/v1beta1/query.rpc.func";

// Now you can query the blockchain
const balance = await getAllBalances(endpoint, {
  address: "cosmos1addresshere",
});

For example, customized hooks are functions that return the result you want:

// Import only what you need
import { defaultContext } from "@tanstack/react-query";
import { useGetBalance } from "@interchainjs/react/cosmos/bank/v1beta1/query.rpc.react";

// Initialize RPC endpoint and address
const { rpcEndpoint } = useQueryHooks(defaultChainName, {
  context: defaultContext,
  enabled: !!address,
});

//Now you can get balance by tree shakable hooks
const balanceRes = useGetBalance({
  request: {
    address: address || "",
    denom: "osmo",
  },
  options: {
    context: defaultContext,
    enabled: !!address && !!rpcEndpoint,
    select: ({ balance }) => balance?.amount,
    staleTime: 0,
  },
  clientResolver: rpcEndpoint,
});

const balance = balanceRes?.data;

Available Helper Types

InterchainJS provides two main types of tree shakable helpers and customized hooks:

1. Query Helpers/Customized Hooks: For retrieving data from the blockchain

   import { getValidator } from "@interchainjs/cosmos/staking/v1beta1/query.rpc.func";
   import { useGetValidators } from "@interchainjs/react/cosmos/staking/v1beta1/query.rpc.react";

2. Transaction Helpers/Customized Hooks: For broadcasting transactions

   import { delegate } from "@interchainjs/cosmos/staking/v1beta1/tx.rpc.func";
   import { useDelegate } from "@interchainjs/react/cosmos/staking/v1beta1/tx.rpc.react";

Example: Combining Query and Transaction Helpers

Here's how you might use both types together in a staking scenario:

// Import helpers
import { createQueryRpc } from "@interchainjs/cosmos/utils";
import { getValidator } from "@interchainjs/cosmos/staking/v1beta1/query.rpc.func";
import { delegate } from "@interchainjs/cosmos/staking/v1beta1/tx.rpc.func";

// Query validator info
const { validator } = await getValidator(endpoint, {
  validatorAddr: "cosmosvaloper1...",
});

// Execute delegation
const result = await delegate(
  signingClient,
  signerAddress,
  {
    delegatorAddress: signerAddress,
    validatorAddress: validator.operatorAddress,
    amount: { denom: "uatom", amount: "1000000" },
  },
  fee,
  "Delegation via InterchainJS"
);

By importing only the specific helpers you need, you ensure that your application bundle remains as small and efficient as possible.

Example: Working with Keplr using InterchainJS React helper hooks

import { DirectSigner } from '@interchainjs/cosmos';
import { defaultContext } from '@tanstack/react-query';
import { useSend } from '@interchainjs/react/cosmos/bank/v1beta1/tx.rpc.react';

// Get Keplr offline signer
await window.keplr.enable(chainId);
const offlineSigner = window.keplr.getOfflineSigner(chainId);

// Create signer
const signer = new DirectSigner(offlineSigner, {
  chainId: 'cosmoshub-4',
  queryClient: queryClient,
  addressPrefix: 'cosmos'
});

const {mutate: send} = useSend({
  clientResolver: signer,
  options: {
    context: defaultContext
  }
})

// Get account info
const accounts = await offlineSigner.getAccounts();
const senderAddress = accounts[0].address;

// Build transfer message
const amount = [{
  denom: "uatom",
  amount: (parseFloat(form.amount) * 1000000).toString() // Convert from ATOM to uatom
}]

// Set fee
const fee = {
  amount: [{
    denom: "uatom",
    amount: "5000" // 0.005 ATOM fee
  }],
  gas: "200000"
};

// Sign and broadcast transaction
send(
   {
    signerAddress: senderAddress,
    message: {
      fromAddress: senderAddress,
      toAddress: form.toAddress,
      amount,
    },
    fee,
    memo: form.memo || "Transfer ATOM via InterchainJS"
  },
  {
    onSuccess: (result) => {
      setTxHash(result.transactionHash);
    },
    onError: (error) => {
      const errorMessage = error instanceof Error ? error.message : 'Unknown error';
      console.error('Transfer failed:', error);
      setError(`Transfer failed: ${errorMessage}`);
    }
  }
)

Example: Working with Keplr using the signer directly

// signer is the same as in the code above
const accounts = await signer.getAccounts();
const senderAddress = accounts[0].address;

const transferMsg = {
  typeUrl: "/cosmos.bank.v1beta1.MsgSend",
  value: {
    fromAddress: senderAddress,
    toAddress: form.toAddress,
    amount // amount is the same as in the code above
  }
};

const result = await signer.signAndBroadcast({
  messages: [transferMsg],
  fee,
  memo: form.memo || "Transfer ATOM via InterchainJS"
});
console.log(result.transactionHash);
