This module provides the necessary utilities, which are required to encode and decode content using different URL encoding mechanisms and algorithms.

This module contains functions to perform file system based operations such as create, delete, rename the file/directory, and retrieve metadata of the file.

This module provides a platform-independent API for working with file paths.

This module provides support for the gRPC messaging protocol. gRPC is an inter-process communication technology that allows you to connect, invoke and operate distributed heterogeneous applications as easily as making a local function call. The gRPC protocol is layered over HTTP/2 and It uses Protocol Buffers for marshaling/unmarshaling messages. This makes gRPC, highly efficient on wire and a simple service definition framework.

This module provides an implementation for connecting and interacting with HTTP, HTTP2, and WebSocket endpoints. The module facilitates two types of network entry points as ‘Client’ and ‘Listener’.

This module is designed to support input and output operations via channels in a canonical way, either in a blocking, or non-blocking manner.

This module provides the API for Java interoperability in Ballerina. It includes a set of Ballerina annotations with which Java constructors, methods, and fields can provide implementations of Ballerina functions with external function bodies.

This module provides an inbound LDAP authentication provider, which is used to authenticate using LDAP credentials.

This module provides a basic API for logging.

This module provides functions to perform fixed-precision integer arithmetic and fixed-precision decimal arithmetic. It includes functions to get the absolute, cosine, sine, root, tangent, and more for a given value.

This module provides functions to encapsulate multiple body parts such as attachments into a single message. The communication of such messages follow the MIME (Multipurpose Internet Mail Extensions) specification as specified in the RFC 2045 standard.

This module provides the capability to connect with NATS and NATS Streaming servers and performs the below functionalities.

This module provides an inbound OAuth2 authentication provider, which can be used to authenticate the provided credentials against an introspection endpoint and an outbound OAuth2 authentication provider, which can be used to authenticate an external endpoint.

This module provides apis for observing Ballerina services. Ballerina supports Observability out of the box. This module provides user api's to make Ballerina Observability more flexible for the user.

This module provides the following code generation capabilities.

RabbitMQ is one of the most popular open-source enterprise messaging systems modelled on the Advanced Message Queuing Protocol (AMQP) standard. This guide covers the Ballerina RabbitMQ module and its public API. This module contains the functionality to support messaging with the RabbitMQ broker (AMQP 0-9-1). It assumes that the most recent version of Ballerina is used and is built on top of the basics.

This module provides utility methods for obtaining reflective information about the Ballerina runtime.

This module provides functions to interact with the runtime, the invocation context, and to manage errors.
