What is GitHub's issue tracking and project management?
Answer
GitHub provides integrated project management tools directly in repositories. Issues are the fundamental unit — used for bug reports, feature requests, tasks, and discussions. Features: markdown formatting, labels (categorize: bug, enhancement, documentation), milestones (group issues for a release/sprint), assignees, linked PRs, reactions. Closing issues from commits: git commit -m "Fix login redirect, closes #123" — when pushed to default branch, automatically closes issue #123. Keywords: closes, fixes, resolves (and variants). Labels: color-coded tags for filtering and triage. Common labels: bug, enhancement, good first issue (for contributors), help wanted, wontfix, duplicate, priority:high. Milestones: group issues/PRs for a sprint or release. Track progress as percentage complete. Projects (GitHub Projects): board and table views with custom fields, status columns, and automation. Can aggregate issues/PRs across multiple repositories. Views: board (Kanban), table (spreadsheet), roadmap. Automation: auto-add new issues to projects, auto-move to "Done" when PR merges. Discussions: forum-style conversations for Q&A, announcements, and general discussions separate from issues.
