# Knative Eventing code samples Use the following code samples to help you understand the various use cases for Knative Eventing and Event Sources. [Learn more about Knative Eventing and Eventing Sources](../eventing/README.md). See [all Knative code samples](https://github.com/knative/docs/tree/main/code-samples) in GitHub. | Name | Description | Languages | | -------------------- | --------------------------------------------------- | --------------------------------------------| | Hello World | A quick introduction that highlights how to deploy an app using Knative. | [Go](https://github.com/knative/docs/tree/main/code-samples/eventing/helloworld/helloworld-go) and [Python](https://github.com/knative/docs/tree/main/code-samples/eventing/helloworld/helloworld-python) | | GitHub source | Shows how to wire GitHub events for consumption by a Knative Service. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/github-source) | | GitLab source | Shows how to wire GitLab events for consumption by a Knative Service. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/gitlab-source) | | Apache Kafka Binding | KafkaBinding is responsible for injecting Kafka bootstrap connection information into a Kubernetes resource that embed a PodSpec (as `spec.template.spec`). This enables easy bootstrapping of a Kafka client. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/kafka/binding) | | Apache Kafka Channel | Install and configure the Apache Kafka Channel as the default Channel configuration for Knative Eventing. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/kafka/channel) | | Writing an event source using JavaScript | This tutorial provides instructions to build an event source in JavaScript and implement it with a ContainerSource or SinkBinding. | [JavaScript](https://github.com/knative/docs/tree/main/code-samples/eventing/writing-event-source-easy-way) | | Parallel with multiple cases | Create a Parallel with two branches. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/parallel/multiple-branches) | | Parallel with mutually exclusive cases | Create a Parallel with mutually exclusive branches. | [YAML](https://github.com/knative/docs/tree/main/code-samples/eventing/parallel/mutual-exclusivity) |
