Compiling the purescript code, supposing nvm is already installed, is as simple as typing:
> nvm install --lts (12.16.1)
> npm install -g purescript@0.13.8
> npm install -g spago@0.15.2
> npm install -g parcel-bundler@1.12.4
> npm install -g sass@1.26.5
> npm install -g yarn@1.22.4
> yarn clean; yarn build
> yarn docs
> yarn develop-app
To support editing Purescript files, there are two useful VSCode plugins:
- PureScript IDE: https://github.com/nwolverson/vscode-ide-purescript
- PureScript Language Support: https://github.com/nwolverson/vscode-language-purescript
In order to have errors highlighted directly into VSCode, you need to set one option into the "PureScript IDE" module:
- "purescript.editorMode": true (Editor Mode: Whether to set the editor-mode flag on the IDE server)
To build the application just execute yarn build; if you want to cleanup the workarea of all temporary files, yarn clean will do it.
To run the application, just type the following two commands in two different terminal windows:
yarn develop-purs# this is only required if your editor is not integrated with the purs compileryarn develop-app# this command will not build the application; it'll just bundle resources to be loaded by the browser
The first command will invoke spago to continuosly compile the PureScript files, while the second will start a web server to serve the application on a local port, reported by ParcelJS logs:
>> starting...
Server running at http://localhost:1234

This is what the calculator should look like:
