# TypeScript project configuration
TypeScript-enabled Strapi applications have a specific project structure with the following dedicated folders and configuration files:
| TypeScript-specific directories and files | Location | Purpose | 
|---|---|---|
| ./distdirectory | application root | Adds the location for compiling the project JavaScript source code. | 
| builddirectory | ./dist | Contains the compiled administration panel JavaScript source code.  The directory is created on the first yarn buildornpm run buildcommand | 
| tsconfig.jsonfile | application root | Manages TypeScript compilation for the server. |

In development mode, the application source code is compiled to the ./dist/build directory and recompiled with each change in the Content-type Builder. To start the application, run the following commands in the root directory:
