bun init is a quick way to start a blank project with Bun. It guesses with sane defaults and is non-destructive when run multiple times.

It creates:

• a package.json file with a name that defaults to the current directory name
• a tsconfig.json file or a jsconfig.json file, depending if the entry point is a TypeScript file or not
• an entry point which defaults to index.ts unless any of index.{tsx, jsx, js, mts, mjs} exist or the package.json specifies a module or main field
• a README.md file

AI Agent rules (disable with $BUN_AGENT_RULE_DISABLED=1):

• a CLAUDE.md file when Claude CLI is detected (disable with CLAUDE_CODE_AGENT_RULE_DISABLED env var)
• a .cursor/rules/*.mdc file to guide Cursor AI to use Bun instead of Node.js and npm when Cursor is detected

If you pass -y or --yes, it will assume you want to continue without asking questions.

At the end, it runs bun install to install @types/bun.
