npm-publish

Provenance Blockchain API NPM publishing container

This repository contains the boilerplate Typescript transpiling code generated by telescope generate (osmosis-labs/telescope) that is bundled into a docker image provenanceio/npm-publish for use in the provenance CI release workflows. It will transpile the provenance Protobuf API into Typescript and publish it as a module to NPM.

Note: this repository does not contain any generated sources.

Usage

RPC Clients

import { provenance } from '@provenanceio/provenance';

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

// now you can query the cosmos modules
const balance = await client.cosmos.bank.v1beta1
    .allBalances({ address: 'provenance1addresshere' });

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

Composing Messages

Import the provenance object from @provenanceio/provenance.

import { provenance } from '@provenanceio/provenance';

const {
    createSpotLimitOrder,
    createSpotMarketOrder,
    deposit
} = provenance.exchange.v1beta1.MessageComposer.withTypeUrl;

CosmWasm Messages

import { cosmwasm } from "@provenanceio/provenance";

const {
    clearAdmin,
    executeContract,
    instantiateContract,
    migrateContract,
    storeCode,
    updateAdmin
} = cosmwasm.wasm.v1.MessageComposer.withTypeUrl;

IBC Messages

import { ibc } from '@provenanceio/provenance';

const {
    transfer
} = ibc.applications.transfer.v1.MessageComposer.withTypeUrl

Cosmos Messages

import { cosmos } from '@provenanceio/provenance';

const {
    fundCommunityPool,
    setWithdrawAddress,
    withdrawDelegatorReward,
    withdrawValidatorCommission
} = cosmos.distribution.v1beta1.MessageComposer.fromPartial;

const {
    multiSend,
    send
} = cosmos.bank.v1beta1.MessageComposer.fromPartial;

const {
    beginRedelegate,
    createValidator,
    delegate,
    editValidator,
    undelegate
} = cosmos.staking.v1beta1.MessageComposer.fromPartial;

const {
    deposit,
    submitProposal,
    vote,
    voteWeighted
} = cosmos.gov.v1beta1.MessageComposer.fromPartial;

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 getSigningprovenanceClient 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 { getSigningprovenanceClient } from '@provenanceio/provenance';

const stargateClient = await getSigningprovenanceClient({
  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 === 'provenance');
  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: 'coin',
        amount: '1000'
    }
    ],
    toAddress: address,
    fromAddress: address
});

const fee: StdFee = {
    amount: [
    {
        denom: 'coin',
        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,
    provenanceAminoConverters,
    provenanceProtoRegistry
} from '@provenanceio/provenance';

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

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

const aminoConverters = {
    ...cosmosAminoConverters,
    ...cosmwasmAminoConverters,
    ...ibcAminoConverters,
    ...provenanceAminoConverters
};

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

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

Developing

When first cloning the repo:

yarn
yarn build

Codegen

Contract schemas live in ./contracts, and protos in ./proto. Look inside of scripts/codegen.js and configure the settings for bundling your SDK and contracts into provenance:

yarn codegen

Publishing

Build the types and then publish:

yarn build:ts
yarn publish
