Miso Start Template

Copy the files and start hacking your Miso app!

Prepare the build

1. Install Nix
   • If you are using macOS 10.15 or newer, check the specific instructions
2. Optionally set up a binary cache:
   1. Install Cachix: nix-env -iA cachix -f https://cachix.org/api/v1/install
   2. Use the Miso cache: cachix use miso-haskell

Build and run the project

nix-build
open ./result/bin/miso-app.jsexe/index.html

Build the project in a nix-shell

nix-shell -A env
cabal build
open `find dist-newstyle/ -name index.html`

Update dependencies

The default.nix file has a couple of lines which indicate the "state of the world" for the build system:

• The version of Miso you are going to use, usually from Git;
• A Hackage snapshot, which can be updated by taking the latest version from all-cabal-hashes.

The example also shows how you can re-wire the Hackage information to make some packages use a different version from the latest (servant in our case), and how to bring a package from a GitHub repository.
