Set up a modern Cosmos app by running one command ⚛️

# install
npm install -g create-cosmos-app

# run one command
create-cosmos-app

> name: my-app
cd my-app
yarn && yarn dev

# now your app is running on localhost:3000!

You don’t need to install or configure cosmjs, keplr, nextjs, webpack or Babel.

Everything is preconfigured, ready-to-go, so you can focus on your code!

• ⚡️ Connect easily to 20+ wallets via Cosmos Kit — including Ledger, Keplr, Cosmostation, Leap, Trust Wallet, OKX, XDEFI, Exodus, Wallet Connect and more!
• ⚛️ Sign and broadcast with cosmjs stargate + cosmwasm signers
• 🎨 Build awesome UI with Interchain UI and Explore Components
• 🛠 Render pages with next.js hybrid static & server rendering

To create a new app, you may choose one of the following methods:

npm install -g create-cosmos-app

Then run the command:

create-cosmos-app

we also made an alias cca if you don't want to type create-cosmos-app:

cca

npx create-cosmos-app

npm init cosmos-app

yarn create cosmos-app

Because the nature of how template boilerplates are generated, we generate yarn.lock files inside of nested packages so we can fix versions to avoid non-deterministic installations.

When adding packages, yarn workspaces will use the root yarn.lock. It could be ideal to remove it while adding packages, and when publishing or pushing new changes, generating the nested lock files.

In the root, to remove all nested lock files:

yarn locks:remove

When you need to remove/generate locks for all nested packages, simply run yarn locks in the root:

yarn locks
