Overview of Code Pipeline
AWS Code Pipeline, an AWS service that automates the deployment of software, is called AWS Code Pipeline. It allows the developer to quickly deliver the code for new updates. It is a continuous delivery service. CodePipeline will build, test, launch, and launch an app every time code changes.
It will reduce development time as it only requires a few manual steps. CodePipeline allows us to easily configure software releases at different stages.
Top Features of CodePipeline
Access Control: We can monitor user activities and control who can modify the code using AWS IAM.
Receive Notification: Amazon SNS notifications can be integrated to allow you to receive notifications. Each notification contains status messages about the events.
Fast Delivery: Users will be able to quickly release new features as soon as there is a new release.
Easy Integration: We can integrate pre-built plugins with your release process.
Quick Start: This service will continue to deliver the service and connect with the current system and tools.
What is Monorepo?
Many organizations use GitHub as a source-code repository. Monorepo is a term that describes multiple applications and services that store the source code for many projects in one repository.
Monorepo is a central repository where all codebases are kept. Every member of the team uses the most current version of the code for their projects. It is a single repository that stores multiple applications and libraries’ codes.
Monorepo has many benefits
Shared code: All code is stored in one repository and all members of the team can access the most recent version. This allows for the sharing of logic between the backend and frontend.
Easy maintenance: All applications that use the shared library are updated when the code is in the library is updated.
Monorepo allows for atomic changes: If there are any code modifications, monorepo makes it easy to coordinate with multiple projects or teams.
Code reuse: Different projects may use the same code from the repository.
Faster code review: Code stored in one repository allows us to quickly track and review any code changes.
Solution Overview
When there is a code change, the release pipeline is invoked automatically. The CodePipeline uses GitHub to source the pipeline. To detect changes in remote branches and start the pipeline, the CodePipeline will use a webhook. The CodePipeline receives an event at the repository level when we make changes to any folder in the monorepo with Github.

The diagram above shows how GitHub events invoke a monorepo-specific pipeline by evaluating an event triggered with Lambda.
You can add customizations to the start pipeline based upon external factors. Custom code can be used to customize whether a pipeline should trigger or not. You can create custom logic to trigger pipelines.
Multiple pipelines can be linked to a single source. Groups allow us to make changes to selected pipelines when multiple pipelines are using the same repo.
Avoid reacting to files that aren’t important: If the file isn’t affecting the application, we can avoid triggering a pipeline.
Sample Architecture Diagram

The following steps are described in the figure:
All changes to the source code are saved in the GitHub repo.
The Webhook will trigger the push event.
API Gateway will authenticate the GitHub push event and then invokes the lambda function
