The usage of a single, common codebase by all developers on a team is emphasized by the software development method known as trunk-based development (TBD). Instead of building feature branches, developers use this method to commit changes straight to the trunk, often known as the main branch. With frequent integrations and codebase validations, this strategy ensures that the code is constantly in a usable state.
Trunk-based development has grown in favor in recent years. This is due to its capacity to shorten development cycles, enhance teamwork, and lessen the likelihood of disputes like merge conflicts. Manual testing and validation can be laborious and prone to mistakes. As a result, Continuous Integration (CI) and Continuous Deployment (CD) are becoming a popular way to achieve trunk-based development.
What’s CI/CD? It’s an automation technique that gives developers a consistent and efficient way to integrate code changes, carry out automated tests, and release software to production. With CI/CD, teams can decrease the time and effort needed to remove new features and updates. They can also improve the quality and dependability of the product by automating build, test, and deployment processes.
Advantages of CI/CD
There are many advantages to automating trunk based development with CI/CD.
First, developers can quickly find and fix problems with automated testing and validation, which reduces the impact on the development cycle and saves time. As a result, there is a lower chance of introducing defects into the codebase. Instead, teams can find faults and flaws earlier in the development process.
Second, automation speeds up teams by minimizing human tasks like creating, testing, and deploying features. Therefore, developers are freed from having to spend time on tedious and time-consuming chores. As a result, teams are empowered to concentrate on building new features and enhancing the user experience.
Finally, automation boosts software quality assurance. Teams can guarantee that the codebase is constantly working by implementing automated testing and validation, which lowers the chance of errors and flaws in production.
Trunk-based Development is a methodology that encourages teamwork, flexibility, and effectiveness in software development.

Continuous Integration (CI) and Continuous Delivery (CD) in the Context of Trunk-Based Development
Software development teams may build, test, and release code fast and reliably thanks to the automation approaches of continuous integration (CI) and continuous delivery (CD). With frequent integrations and validations, CI/CD is essential for guaranteeing that the codebase is constantly in working condition.
What Are the Differences Between CI and CD?
Constantly integrating updated code into a shared repository, where it is automatically produced and tested, is known as continuous integration. This minimizes the possibility of introducing bugs into software by ensuring that errors or conflicts are found early in the development cycle. Using CI, developers may find problems fast and fix them before they have a chance to affect the rest of their team.
Automating the deployment of code changes to production is known as continuous delivery. Through CD, teams can quickly and reliably release new features and upgrades with little risk and delay. This greatly decreases the time and effort needed to remove software while simultaneously improving the quality and dependability of the product by automating the deployment process.
Teams that practice trunk-based development through CI/CD receive faster feedback. They can detect problems early and save time and effort through constant validation. This frees up developers to concentrate on building new features and enhancing the user experience rather than troubleshooting problems.
What are the appropriate platforms and technologies to help implement CI/CD in trunk-based development? Jenkins, Travis CI, CircleCI, and GitLab CI/CD are some standard CI/CD tools. These solutions allow teams to accelerate the development cycle with capabilities like automated testing, build automation, and deployment automation.
After choosing the right tools and platforms, teams must establish the CI/CD pipeline phases for trunk-based development. Any pipeline should be separated into stages for creating, testing, and deployment. Plus, each stage should be designed to give the development team prompt and accurate input. Set up the appropriate pipeline to ensure that code updates are validated quickly and accurately.
Teams should use code to put the CI/CD pipeline into practice. By specifying the pipeline steps and configuration in code, version control, collaboration, and automation become simpler. As a result, they can grow and optimize their development process with the help of code-based pipelines, guaranteeing uniformity and dependability within the group.
