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.
