CosmWasmJS is outdated and unmaintained.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 The code here serves as a historical reference.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.
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.
