I’m new to Haskell, however I have plenty experience building apps in Django and Rails, and all of the slides’ issue is very relevant in building production app. The slide make me worried I decide to start building a small, yet product-ready app to explore the Haskell eco system for my self.

This week’s Haskell Weekly (issue 82) include an interesting slide of one developer sharing his experience rewriting a Rails project using Haskell. You can read the slide here:

[Slides] Joy & frustration of putting 34,000 lines of Haskell into production

I’m new to Haskell, however I have plenty experience building apps in Django and Rails, and all of the slides’ issue is very relevant in building production app. The slide make me worried I decide to start building a small, yet product-ready app to explore the Haskell eco system for my self.

In this project we’re going to build a Twitter clone. I will also focus on making it as close to production ready as possible, in the same spirit of the Rails tutorial https://www.railstutorial.org/book. The app will include

• Database model definition and querying
• Database migration
• Deployment, with continuous integration and delivery
• Testing: unit test and integration tests
• Logging and incident reporting
• Instrument and optimization
• Form validation
• RESTFul API and JSON serialize
• Caching
• Authentication and authorization
• l10n and i18n

In the end of each week there will be a summary post. Stay tune!
