The default shell `devShell` works by adding a default `shell` to all projects. You can pass the shell arguments to the project function using the new `shell` argument:
```
let myProject = haskell-nix.project {
src = ./.;
shell.tools = { cabal = {}; };
shell.crossPlatforms = p: [ p.cross ];
};
```
This will include js-unknown-ghcjs-cabal in the `devShell`.
To add cross compiled outputs to the flake pass `crossPlatforms` to the `flake` function.
```
myProject.flake { crossPlatforms = p: [ p.cross ]; }
```
To cross compile a component include the platforms `config` string to the output name like this
```
nix build .#js-unknown-ghcjs:pkg-name:lib:pkg-name
```
