Integrating everyone's work into one shared line at least daily, keeping branches short-lived and hiding unfinished work behind flags, reduces merge conflicts and makes continuous integration real.

What it is

Trunk-based development means that all developers integrate into a single shared branch ("trunk", usually main) frequently, typically at least once a day. Branches, where used, live for hours or a few days and are merged as soon as the change passes the build. Larger changes are made in small steps that keep the trunk releasable, using feature flags or branch-by-abstraction to hide incomplete work.

Why it matters

Fowler's description of continuous integration rests on frequent integration to a mainline with a self-testing build; long-lived branches defer the integration and hide conflicts until they are expensive. Short-lived branches keep review scope small and let the pipeline verify the actual combined state rather than isolated work.

How to apply

Break work into steps that can each be merged without breaking the trunk.
Guard unfinished behaviour with a flag rather than a branch.
Run the full build and tests on every merge; treat a red trunk as the team's first priority.
Cut releases from the trunk by tag; use release branches only for supported older versions.

Pitfalls

Without a fast, reliable build the model collapses into "everybody breaks main". Flags that are never removed become permanent complexity. Teams new to the approach often merge too rarely rather than too often.
