# Unmaintained ⚠️

CosmWasmJS is outdated and unmaintained. See https://medium.com/cosmwasm/dev-note-2-why-we-are-sunsetting-cosmwasmjs-61d8706418e6.

There is no 1:1 alternative but https://cosmology.tech/ might be a helpful resource for bootstrapping dapps with wallet connections.

The code here serves as a historical reference. We hope it is useful one way or another.

## About

Cosmwasm.js was created to help new developers get started with their first

dApps. It is just a wrapper package to easily import needed features from

CosmJS.

## Get started

### Installation

**NPM**

`npm install cosmwasm`

**Yarn**

`yarn add cosmwasm`

## Usage

### Get a read-only cosmwasm client

```ts

import { CosmWasmClient } from "cosmwasm";

// This is your rpc endpoint

const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";

async function main() {

  const client = await CosmWasmClient.connect(rpcEndpoint);

  console.log(client);

}

main();

```

### Create a wallet and a signing stargate client

```ts

import { SigningCosmWasmClient, Secp256k1HdWallet } from "cosmwasm";

// This is your rpc endpoint

const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";

// Using a random generated mnemonic

const mnemonic =

  "rifle same bitter control garage duck grab spare mountain doctor rubber cook";

async function main() {

  // Create a wallet

  const wallet = await Secp256k1HdWallet.fromMnemonic(mnemonic);

  // Using

  const client = await SigningCosmWasmClient.connectWithSigner(

    rpcEndpoint,

    wallet,

  );

  console.log(client);

}

main();

```

### Connect with keplr and get a signing starget client

```ts

import { setupWebKeplr } from "cosmwasm";

const config = {

  chainId: "cliffnet-1",

  rpcEndpoint: "https://rpc.cliffnet.cosmwasm.com:443/",

  prefix: "wasm",

};

async function main() {

  const client = await setupWebKeplr(config);

  console.log(client);

}

main();

```

### Connect with Cosmostation and get a signing starget client

```ts

import { setupCosmostation } from "cosmwasm";

const config = {

  chainId: "cliffnet-1",

  rpcEndpoint: "https://rpc.cliffnet.cosmwasm.com:443/",

  prefix: "wasm",

};

async function main() {

  const client = await setupCosmostation(config);

  console.log(client);

}

main();

```

### Interacting with contracts

```ts

import { CosmWasmClient } from "cosmwasm";

// This is your rpc endpoint

const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";

// This is your contract address

const contractAddr =

  "wasm19qws2lfd8pskyn0cfgpl5yjjyq3msy5402qr8nkzff9kdnkaepyqycedfh";

async function main() {

  const client = await CosmWasmClient.connect(rpcEndpoint);

  const config = await client.queryContractSmart(contractAddr, { config: {} });

  console.log(config);

}

main();

```
