Programming Opa: Web development, reimagined
MLstate's Opa streamlines Web app development with a single language for client and server, but the bright promise is not without pitfalls
Not only are today's diverse technologies difficult to master, they complicate security. Each boundary between the different domains requires a communication mechanism that passes data between those technologies. And each of these communication conduits can be exploited, as attackers can intercept data or inject damaging information.

Opa tackles these issues from a fresh angle. With Opa, you write your Web application as though it were a single-tier program, and the compiler handles the knotty details of partitioning your program and deploying the resulting components to their proper domains. The compiler also builds the communication infrastructure among application components, and that infrastructure is invisibly managed by the runtime. The security weaknesses inherent in today's Web applications are virtually eliminated.
