@stargazefi/api

A client library for the Stargaze blockchain.

🚧 Warning

This API is still under heavy construction, be ready for unexpected breaking changes.

Get Started

The library exposes one main TypeScript class: the StargazeApi class. Here is an example of fetching the user's balance.

import { StargazeApi } from '@stargazefi/api';
import { QueryClientImpl } from '@stargazefi/api/lib/generated/cosmos/bank/v1beta1/query';

// Create a new instance of the StargazeApi class.
const api = StargazeApi.connect({
	// StargazeApi supports multiple client connections to interact with a node:
	// - via the Tendermint RPC
	// - via gRPC
	// - via gRPC-web
	// - via REST and gRPC-gateway
	connection: {
		// Here, we are using the Tendermint RPC client connection.
		type: 'tendermint',
		url: 'http://devnet.stargaze.fi:26657',
	},
});

// Create a client for the x/bank module.
const bankClient = new QueryClientImpl(api.connection.queryConnection);
// Fetch the balance of an address.
const myAddress = 'stars1j9...';
const balances = await bankClient.AllBalances({
	address: myAddress,
});

console.log(balances); // Prints `{"balances":[{"denom":"utree","amount":"10000000000"}],"pagination":{"total":1}}`

import { StargazeApi } from '@stargazefi/api';

// Same as above.
const api = new StargazeApi({ ... });

// Fetch the balance of an address with new API.
const myAddress = 'stars1j9...';
const balances = await api.query.cosmos.bank.v1beta1.AllBalances({
address: myAddress,
});

console.log(balances); // Prints `{"balances":[{"denom":"utree","amount":"10000000000"}],"pagination":{"total":1}}`

Feel free to comment on issue #2 if you have ideas of user-facing APIs you'd like to see.

Documentation

The list of all available methods to call can be found in:

• Cosmos SDK Docs for all other modules (x/bank, x/staking...)

Alternatively, you can just explore the ./src/generated/ folder, all methods are commented in the code.

Differences with CosmJS

The main difference with CosmJS is that StargazeJS is 100%-generated TS client, while CosmJS recommends manually decorating your own TS classes. For this code generation, StargazeJS uses ts-proto. However, the generated types create imcompatibilities with CosmJS (which uses protobufjs).

Long-term Roadmap

• Create a "JS Client generator": you input some proto files, the generator outputs a fully-functional TS client.
• Make it compatible with CosmJS.
