# PureScript-Cookbook



An unofficial Cookbook for PureScript

([Quick link to recipes table](./README.md#recipes))



The recipes folder contains all the recipes in this repo in no particular order.



If you want to contribute a new recipe, see the [CONTRIBUTING.md](./CONTRIBUTING.md) file.



## Usage



### Install Dependencies



Install GNU Make (version 4.0 or above), and verify installation with:

```

make --version

```



Install all dependencies locally:

```

make installDeps

```



Install for Nix users:

```sh

# Remove purescript and spago and removing trailing , from package.json

sed --in-place '/purescript\|spago/d' ./package.json && sed --in-place '$!N;s/,\n  }/\n  }/;P;D' package.json

nix-shell

```



### Running Recipes



See a list of available recipe launch commands by running `make list`:

```

> make list

Use "make RecipeName-target" to run a recipe



=== Node Recipes ===

make ReadPrintFileContents-node

make HelloLog-node

...



=== Web Recipes ===

make WindowProperties-web

make HelloLog-web

...

```



Then simply copy and paste one of the listed commands. For example:



Running a node-compatible recipe:

```

> make HelloLog-node

=== Running HelloLog on the Node.js backend ===

[info] Installation complete.

[info] Build succeeded.

Hello world!

```



Running a web-compatible recipe:

```

> make HelloLog-web

=== Building HelloLog ===

[info] Installation complete.

[info] Build succeeded.

=== Launching HelloLog in the web browser ===

...

```
