What is the Conventional Commits specification and why is it useful?

Conventional Commits is a lightweight convention on top of git commit messages. It provides an explicit structure (type, optional scope, description, optional body and footer) that enables automated semver bumping, automated changelog generation, and clear project commit histories for software development teams.

When should I use feat vs fix vs chore in commit messages?

Use feat when introducing new user-facing functionality (corresponds to a MINOR version bump). Use fix when patching a bug in user-facing behavior (corresponds to a PATCH version bump). Use chore for maintenance tasks, dependency updates, or tooling configuration without changing src or test code.

How do I indicate a breaking change in Conventional Commit format?

You can signal a breaking change in two ways: by adding an exclamation mark ! after the type/scope (e.g., feat(api)!: change user endpoint payload), or by including a BREAKING CHANGE: footer at the bottom of the commit body describing the migration steps.

What are the standard rules for commit subject line length and casing?

Conventional Commit descriptions should be written in imperative, present-tense mood ("add feature" not "added feature"), start with a lowercase letter, and omit a trailing period. The first line should stay under 50-72 characters so tools like GitHub and git log avoid truncating the summary.

How do optional scopes help organize multi-package monorepos?

Adding a scope in parentheses after the commit type (such as feat(auth): add JWT token refresh or fix(ui): adjust button padding) provides immediate context on which component, module, or package in a repository or monorepo was affected by the commit.

How does semantic-release utilize Conventional Commits for automated publishing?

Automation frameworks like semantic-release parse git commit messages in CI pipelines. Commits starting with fix trigger patch releases, feat triggers minor releases, and BREAKING CHANGE or ! triggers major releases, publishing npm or Docker artifacts automatically without manual intervention.

Is any of my git commit history or ticket information uploaded anywhere?

No. The semantic commit generator runs entirely within your browser DOM via local client-side JavaScript. Your ticket IDs, issue descriptions, code summaries, and commit messages are never sent to remote servers or stored outside your browser session.

Can I use this generator with git commit templates or hooks like Husky?

Yes! You can copy the generated conventional commit string directly into your command line (git commit -m "..."), or use generated outputs as templates for commitlint, Husky pre-commit hooks, or interactive commit wizards like Commitizen in your development environment.

Why use a Conventional Commit message generator for git history?

Writing clear, structured git commit messages is one of the most effective practices for maintaining a healthy codebase. A standardized commit history makes pull requests easier to review, simplifies debugging during git bisect sessions, and serves as an immutable log of architectural decisions.

The Conventional Commits specification standardizes message structures so that automated tooling—such as semantic-release, commitlint, and automated changelog generators—can parse git logs without human intervention. An interactive semantic commit helper simplifies formatting by assembling valid commit strings with exact type tags, scope annotations, breaking change footers, and multi-line descriptions.

Standardized Commit Types: Choose from standard conventional types including feat (features), fix (bug fixes), docs (documentation), style (formatting), refactor (code restructure), perf (performance), test (testing), and chore (maintenance).
Scope & Issue Tracking Integration: Add contextual module scopes (e.g., auth, checkout, api) and ticket IDs (e.g., PROJ-123) for seamless traceability between code commits and issue trackers like Jira, Linear, or GitHub Issues.
Breaking Change Formatting: Automatically append the ! indicator and BREAKING CHANGE: footer block to signal major releases to CI/CD automation pipelines.
Character Limit & Formatting Enforcement: Enforce the 72-character subject line limit, imperative mood ("add" instead of "added"), lowercase start, and trailing period removal to meet git best practices.

Conventional Commit specification & changelog parser architecture

The Conventional Commits specification defines a structural layout: <type>[optional scope]: <description>, followed by an optional body and optional footers. Our builder engine validates each section against the formal specification rules in real time.

When building the final commit string, the generator escapes shell characters and formats multi-line message flags (git commit -m "..." -m "...") so you can paste directly into Bash, Zsh, PowerShell, or command prompt terminals without syntax errors.

Client-side security for private commit messages

Your commit summaries, code context details, internal ticket keys, and commit body notes are processed exclusively inside your web browser. No repository data or commit texts are transmitted across external networks or stored in cloud databases.

Step-by-step guide to generating semantic commit messages

Select Commit Type & Scope: Choose the appropriate commit type (e.g., feat, fix, refactor) and enter an optional module scope (e.g., ui or database).
Enter Description & Details: Type a concise summary in imperative mood. Optionally fill out the detailed body paragraph and ticket reference numbers.
Copy & Execute Git Command: Copy the formatted git commit command or commit message string and paste it into your terminal or git client.

How to Generate Conventional Semantic Commit Messages

Select Commit Type & Scope: Choose the commit type (feat, fix, docs, chore, refactor) and enter an optional scope tag (e.g. auth, api, or ui).
Enter Imperative Summary & Details: Type a concise description under 72 characters, and add optional body notes or issue ticket IDs.
Copy CLI Command: Copy the assembled git commit -m command or raw message string directly into your terminal or git client.

Supported Inputs & Output Formats

Input specifications and output delivery details for this utility.
Type	Format	Details & Handling
Input	`Commit Details`	Commit type tag, scope annotation, short description, optional body, ticket numbers, and breaking change flag.
Output	`Conventional Commit Command`	Standardized command line string ready to execute directly in Bash, PowerShell, or Git terminal.

Common Practical Use Cases

Automated Semantic Versioning: Prepare commit histories that feed directly into semantic-release or standard-version CI automation.
Monorepo Package Scoping: Clearly designate affected packages (e.g. core, client, ui) across team commits.
Automated Release Notes: Maintain clean, machine-readable git log messages for automatic changelog generation.

Important Limitations & Technical Boundaries

Formatting assistant: Produces structured commit strings according to the Conventional Commits 1.0.0 specification; does not directly execute git commands or modify git repositories.
