Opa is a functional programming language for web development that compiles to JavaScript, letting developers write frontend and backend code in one language. It ships a compiler plus a runtime JavaScript library, with built-in database query support for PostgreSQL, MongoDB, and CouchDB and a Node.js-based server runtime.
Use cases
- build full-stack web apps in a single language
- write client and server code without manual AJAX calls
- compile a functional language to JavaScript
- query SQL and NoSQL databases from application code
- develop web applications with a strong static typechecker
When to choose
- you want one language for both frontend and backend web code
- you value strong static typing with type inference in web development
- you want database queries integrated into the language
When to avoid
- you need a mainstream ecosystem with active community and hiring pool
- you require frequent updates or modern tooling support
- you want to avoid AGPL-licensed compiler toolchains in a hosted platform
