Nix is a requirement to set up and start a local development environment with Composable's code. We recommend using the Zero-to-Nix installer. Refer to our docs for how to install and configure Nix.

After configuration, familiarise yourself with the following commands:

nix develop in to enter dev shell (command line, variables, tools, compilers).

nix run "composable#devnet-picasso" to run local devnet for CosmWasm development.

nix run "composable#fmt" format all files.

nix build "composable#unit-tests" check unit tests.
