Get Started

Installation

Yarn

yarn add cosmwasm

NPM

npm i cosmwasm

So your package.json should look like:

{
  "name": "cosmwasm",
  "version": "1.0.0",
  "description": "Your Project",
  "dependencies": {
    "cosmwasm": "latest",
    ...
  },
  ...
}

CosmWasmJS in the browser

You can access all the objects of the cosmwasm from the global cosmwasm object if you load CosmWasmJS with a <script> tag.

Include the following in your browser:

<script
  crossorigin
  src="https://unpkg.com/cosmwasm/dist/bundle.js"
></script>

Basics

Clients

You don’t need to do any configuration to get started. It is only important to understand when you need to import which symbols from the package.

Basically there are 2 different clients:

• CosmWasmClient This client can only read. You do not need to have a wallet to instantiate this one. Only an rpcUrl is needed. For a more detailed description please refer to the 🔗 CosmWasmClient Docs.

• CosmWasmSigningClient This client can also write. In order to instantiate it, a wallet must be specified in addition to the rpcUrl. To facilitate the instantiation, CosmWasmJS already comes with some setup functions. For a more detailed description please refer to the 🔗 CosmWasmSigningClient Docs.
