Welcome to the Ballerina Library, a robust collection of libraries designed to empower developers with all the necessary tools for building networked applications. With its "Batteries included" approach, it offers a refined set of building blocks and APIs for quick and dependable application development. Key libraries include HTTP, GraphQL, WebSocket, and gRPC, among others, which are comprehensively listed in the Status Dashboard section.
Every package within the Ballerina Library is readily accessible on Ballerina Central. Updates, encompassing enhancements and bug fixes, are made instantly available to users, ensuring a seamless development experience without having to wait for the broader Ballerina language releases.
This repository serves as the central hub for the Ballerina Library, facilitating discussions, bug reports, feature requests, and an overview of project boards.
For continuous delivery, each library package is maintained in its own repository. To explore the codebase, please visit the respective repository.
The governance, security, release cadence, backward compatibility, and overall maintenance of both parent and child repositories are the responsibility of the dedicated Ballerina Library team.

These are the generated Ballerina connector modules that are used to connect to third-party services. They are published under the ballerinax organization. The modules are generated using the Ballerina OpenAPI tool using the third-party service's OpenAPI definition. Since these are auto-generated, they only contain a smoke test suite rather than a comprehensive test suite. Due to this nature, the code coverage and load test results are not applicable for these modules. Some repositories such as sap.s4hana.sales contain multiple connectors which are highly co-related. These have multiple releases and thus not indicated here.
