What does squash mean in software engineering?

Squash has two main meanings in tech. First, in Git workflows, it means to combine multiple commits into a single commit to create a cleaner project history. Second, it means to quickly find and fix bugs or issues, often used when problems are discovered close to deployment. Both meanings convey the idea of compressing or consolidating something into a simpler, more manageable form.

How do you use squash in a sentence at work?

You can say things like We need to squash these bugs before launch or Can you squash your commits when you rebase? The first example uses it as fixing issues; the second uses it in the Git context. Both are common in tech teams.

Is squash formal or informal?

Squash is casual to neutral in formality. It is very common in engineering teams and code reviews, but you would not use it in formal executive presentations. It is appropriate for standups, pull request comments, and team meetings among developers.

Why do developers squash commits?

Squashing commits creates a cleaner Git history by combining many small, incremental commits into one logical commit. This makes it easier to understand what changes were made and to review the code. It is especially useful before merging feature branches into the main branch.

What is the difference between squash and fix?

While squash and fix are related, squash emphasizes urgency and speed, often implying that multiple issues or commits need to be handled quickly or compressed together. Fix is more general and does not carry that same sense of consolidation or urgency.
