Modules
auth | This module provides default authentication provider configurations that can be extended to create new authentication providers. |
bir | |
cache | This module offers a cache that supports time-based eviction, and size-based eviction. This means that entries are removed from the cache once the expiry time has elapsed (i.e., time-based eviction), or when the cache runs out of space (i.e., size-based eviction). Caching is useful when a value takes significant cost or time to compute and retrieve, and it is therefore useful to cache it for future use. |
config | The |
crypto | This module provides the necessary utilities that are required to hash content using different hashing mechanisms and algorithms. |
encoding | This module provides the necessary utilities that are required to encode and decode content using different encoding mechanisms and algorithms. |
file | This module contains functions to perform file system based operations. |
filepath | The file path module implements the utility functions for manipulating the file path in a way that is compatible with the target operating system. This module uses either forward slashes or backslashes, depending on the operating system. |
grpc | This module contains functions to support gRPC protocol based communication. gRPC is a framework developed by Google to support the RPC (Remote Procedure Call) protocol. The gRPC protocol is layered over HTTP/2. This protocol only supports client-initiated communication. |
http | This module provides an implementation for connecting and interacting with HTTP, HTTP2, and WebSocket endpoints. The module facilitates two types of endpoints as ‘Client’ and ‘Listener’. |
internal | |
io | This module is designed to support input and output operations via channels in a canonical way, either in a blocking, or non-blocking manner. |
java | 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 to Ballerina functions with external function bodies. |
java.jdbc | This module provides the functionality required to access and manipulate data stored in any type of relational database that is accessible via Java Database Connectivity (JDBC). |
jvm | |
jwt | This module provides a inbound and outbound JWT authentication provider, which can be used to authenticate using a JWT and the functionality related to issuing a JWT and validating it. |
kafka | |

lang.typedesc | This module provides lang library operations on |
lang.value | This module provides lang library operations for all values defined by the language specification 2019R2. |
lang.xml | This module provides lang library operations on |
ldap | This module provides inbound LDAP authentication provider, which can be used to authenticate using LDAP credentials. |
log | This module provides a basic API for logging. |
math | 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. |
mime | This module provides functions to encapsulate multiple body parts, such as attachments in a single message. The communication of such messages follow the MIME (Multipurpose Internet Mail Extensions) specification as specified in the RFC 2045 standard. |
nats | NATS is a simple, secure, and high-performance open source messaging system for cloud-native applications. The 'ballerina/nats' module provides the capability to connect with NATS and Streaming servers and perform the following functionalities. |
oauth2 | This module provides an inbound and outbound OAuth2 authentication provider, which can be used to authenticate the provided credentials against an introspection endpoint and authenticate with an external endpoint. |
observe | 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. |
openapi | This module provides the following code generation capabilities to Ballerina: |
rabbitmq | RabbitMQ is one of the most popular open-source enterprise messaging systems, modeled on the Advanced Message Queuing Protocol (AMQP) standard. This guide covers Ballerina RabbitMQ module and its public API. This module contains functionality to support messaging with RabbitMQ broker (AMQP 0-9-1). |
reflect | This module provides utility methods for obtaining reflective information about the Ballerina runtime. |
runtime | This module includes functions to interact with the runtime, the invocation context and to manage errors. |
socket | This module provides an implementation for connecting to a remote socket server or acts as a server for an incoming socket request. The module facilitates two types of endpoints called |
streams | |
system | This module contains functions to retrieve information about the system and the current users of the system. |
task | Task Listeners and Task Schedulers can be used to perform tasks periodically. This module provides the functionality to configure and manage Task Listeners and Task Schedulers. |
test | |
