Write apps like equations!
Code as simple and precise as Mathematical Expressions. Presto is written in PureScript harnessing the powers of Functional Programming & Category Theory. What you get is scalable, performant code with elegant abstractions. Our attempt with Presto is to really simplify the app development process.
You can get your hands dirty by building a mobile recharge app using Presto
git clone https://github.com/juspay/purescript-presto.git cd purescript-presto/examples/billpay-react npm i bower i npm start
Open http://localhost:8080/dist/ in your browser.
billPayFlow :: Flow BillPayFailure StatusScreenAction billPayFlow = do _ <- UI.splashScreen operators <- Remote.fetchOperators operator <- UI.chooseOperator operators mobileNumber <- UI.askMobileNumber amount <- UI.askAmount result <- Remote.payBill mobileNumber amount operator UI.billPayStatus mobileNumber amount result
See examples directory for more samples.
