# Project Structure

> What's inside a scaffolded Twenty app — files, folders, and what each one does.

A new app generated by `npx create-twenty-app` looks like this:

```text filename="my-twenty-app/" theme={null}
my-twenty-app/
  package.json
  src/
    application-config.ts                   # Required — your app's entry point
    default-role.ts                         # Permissions for logic functions
    constants/
      universal-identifiers.ts              # Auto-generated UUIDs and metadata
    __tests__/
      setup-test.ts
      app-install.integration-test.ts
  .github/workflows/ci.yml                  # GitHub Actions
  public/                                   # Static assets
  vitest.config.ts                          # Test runner config
  tsconfig.json, tsconfig.spec.json
  .nvmrc, .yarnrc.yml, .oxlintrc.json
  README.md, LLMS.md
```

## Key files

| File / Folder                            | Purpose                                                        |
| ---------------------------------------- | -------------------------------------------------------------- |
| `src/application-config.ts`              | **Required.** The main configuration file for your app.        |
| `src/default-role.ts`                    | Default role controlling what your logic functions can access. |
| `src/constants/universal-identifiers.ts` | Auto-generated UUIDs and metadata (display name, description). |
| `src/__tests__/`                         | Integration tests (setup + example test).                      |
| `public/`                                | Static assets (images, fonts) served with your app.            |

<Note>
  **File organization is up to you.** The folders above are conventions — the SDK detects entities via AST analysis on `export default defineEntity(...)` calls regardless of where the file lives.
