injectivejs

usage

npm install injectivejs

RPC Clients

import { injective } from 'injectivejs';

const { createRPCQueryClient } = injective.ClientFactory; 
const client = await createRPCQueryClient({ rpcEndpoint: RPC_ENDPOINT });

// now you can query the cosmos modules
const balance = await client.cosmos.bank.v1beta1
    .allBalances({ address: 'inj1addresshere' });

// you can also query the injective modules
const balances = await client.injective.exchange.v1beta1
    .exchangeBalances()

Connecting with Wallets and Signing Messages

⚡️ For web interfaces, we recommend using cosmos-kit. Continue below to see how to manually construct signers and clients.

Here are the docs on creating signers in cosmos-kit that can be used with Keplr and other wallets.

Initializing the Stargate Client

Use getSigningInjectiveClient to get your SigningStargateClient, with the proto/amino messages full-loaded. No need to manually add amino types, just require and initialize the client:

import { getSigningInjectiveClient } from 'injectivejs';

const stargateClient = await getSigningInjectiveClient({
  rpcEndpoint,
  signer // OfflineSigner
});

Creating Signers

To broadcast messages, you can create signers with a variety of options:

• cosmos-kit (recommended)
• keplr
• cosmjs

Amino Signer

Likely you'll want to use the Amino, so unless you need proto, you should use this one:

import { getOfflineSignerAmino as getOfflineSigner } from 'cosmjs-utils';

Proto Signer

import { getOfflineSignerProto as getOfflineSigner } from 'cosmjs-utils';

WARNING: NOT RECOMMENDED TO USE PLAIN-TEXT MNEMONICS. Please take care of your security and use best practices such as AES encryption and/or methods from 12factor applications.

import { chains } from 'chain-registry';

const mnemonic =
  'unfold client turtle either pilot stock floor glow toward bullet car science';
  const chain = chains.find(({ chain_name }) => chain_name === 'injective');
  const signer = await getOfflineSigner({
    mnemonic,
    chain
  });

Broadcasting messages

Now that you have your stargateClient, you can broadcast messages:

const { send } = cosmos.bank.v1beta1.MessageComposer.withTypeUrl;

const msg = send({
    amount: [
    {
        denom: 'inj',
        amount: '1000'
    }
    ],
    toAddress: address,
    fromAddress: address
});

const fee: StdFee = {
    amount: [
    {
        denom: 'inj',
        amount: '864'
    }
    ],
    gas: '86364'
};
const response = await stargateClient.signAndBroadcast(address, [msg], fee);

Advanced Usage

If you want to manually construct a stargate client

import { OfflineSigner, GeneratedType, Registry } from "@cosmjs/proto-signing";
import { AminoTypes, SigningStargateClient } from "@cosmjs/stargate";

import { 
    cosmosAminoConverters,
    cosmosProtoRegistry,
    cosmwasmAminoConverters,
    cosmwasmProtoRegistry,
    ibcProtoRegistry,
    ibcAminoConverters,
    injectiveAminoConverters,
    injectiveProtoRegistry
} from 'injectivejs';

const signer: OfflineSigner = /* create your signer (see above)  */
const rpcEndpint = 'https://rpc.cosmos.directory/injective'; // or another URL

const protoRegistry: ReadonlyArray<[string, GeneratedType]> = [
    ...cosmosProtoRegistry,
    ...publicawesomeProtoRegistry,
    ...cosmwasmProtoRegistry,
    ...ibcProtoRegistry,
    ...injectiveProtoRegistry
];

const aminoConverters = {
    ...cosmosAminoConverters,
    ...publicawesomeAminoConverters,
    ...cosmwasmAminoConverters,
    ...ibcAminoConverters,
    ...injectiveAminoConverters
};

const registry = new Registry(protoRegistry);
const aminoTypes = new AminoTypes(aminoConverters);

const stargateClient = await SigningStargateClient.connectWithSigner(rpcEndpoint, signer, {
    registry,
    aminoTypes
});
