About Ballerina

Ballerina is a compiled, transactional, statically and strongly typed programming language with textual and graphical syntaxes. Ballerina incorporates fundamental concepts of distributed system integration into the language and offers a type-safe, concurrent environment to implement microservices with distributed transactions, reliable messaging, stream processing, and workflows.

Ballerina is a language designed to be integration simple. Based around the interactions of sequence diagrams, Ballerina has built-in support for common integration patterns and connectors, including distributed transactions, compensation and circuit breakers. With first-class support for JSON and XML, Ballerina makes it simple and effective to build robust integration across network endpoints.

Key Features of Ballerina

Cloud native

Network primitives in the language make it simpler to write services and run them in the cloud.

Flexibly typed

Structural types are used for static typing within a program and describing service interfaces.

Data oriented

Type-safe, declarative processing of JSON, XML, and tabular data with language-integrated queries.

Graphical

Programs have both a textual syntax and an equivalent graphical form based on sequence diagrams.

Concurrent

Easy and efficient concurrency with sequence diagrams and language-managed threads.

Reliable, maintainable

Explicit error handling, static types, and concurrency safety combined with a familiar syntax.

Calculator Service
Calculator Service
Level 2

HTTP endpoints are better with type checking. Adding a Record type to a POST request will ensure the correct data is sent every time.

Echo Service
Echo Service
Level 1

Creating a service in ballerina is easy. Now you can add a query parameter and a relative path.

Service Error Handling
Service Error Handling
Level 2

Implement various kinds of error handling and resource management.
