# App Layouts ## When to Use This Skill Use this skill when: - Creating a new ColdBox application from scratch and choosing a project structure - Deciding between the `flat`, `boxlang`, and `modern` application templates - Scaffolding via `box coldbox create app skeleton=<name>` - Understanding directory conventions for an existing app - Migrating from one layout to another ## Language & Engine Compatibility | Layout | CFML (Adobe CF / Lucee) | BoxLang | |--------|------------------------|---------| | `flat` | Yes | Yes | | `boxlang` | No | Yes only | | `modern` | Yes | Yes | > **Default**: The ColdBox CLI (`coldbox create app`) defaults to the `boxlang` skeleton. Pass `--cfml` or `skeleton=flat` / `skeleton=modern` to use another layout. ## Flat Layout **Template repo**: <https://github.com/coldbox-templates/flat> The flat layout places all application code directly in the web root. It is the traditional ColdBox structure and the widest-compatibility choice — works with Adobe ColdFusion, Lucee, and BoxLang. ### Flat: Directory Map ``` / ├── Application.cfc # App bootstrap ├── index.cfm # Front controller ├── box.json # CommandBox package descriptor ├── server.json # Server configuration ├── pom.xml # Maven Java dependencies (optional) │ ├── config/ │ ├── ColdBox.cfc # Framework settings │ ├── Router.cfc # URL routing │ └── WireBox.cfc # D
