bunfig.toml Configuration
Configure Bun behavior with the bunfig.toml config file
toml
# bunfig.toml — project-level Bun config
[install]
peer = false # Don't install peer deps
exact = true # Use exact versions
[test]
coverage = true # Enable code coverage💡 bunfig.toml is optional — Bun works with sensible defaults out of the box
⚡ Use ~/.bunfig.toml for global settings that apply to all projects
📌 Environment variables can be referenced with $VAR_NAME syntax in the config
🟢 install.exact = true pins versions without ^ or ~ — great for reproducible builds
