# Typescript Configuration in SOMOD Module

---

SOMOD's typescript configuration helps to compile the source code into the distributable format.

SOMOD uses a predefined set of typescript definitions in the `tsconfig.somod.json` file.

The content of the `tsconfig.somod.json` file is as follows

```json
{
  "compilerOptions": {
    "allowUmdGlobalAccess": true,
    "outDir": "build",
    "declaration": true,
    "target": "ES5",
    "module": "ESNext",
    "rootDir": "./",
    "moduleResolution": "Node",
    "esModuleInterop": true,
    "importHelpers": true,
    "skipLibCheck": true,
    "jsx": "react-jsx"
  },
  "include": ["lib", "serverless", "ui"]
}
```

Any extra configurations are allowed, but these configurations must be present and not altered.

> - Typescript compilation is skipped if `tsconfig.somod.json` is not present
> - When build is run with `--ui` option, the typescript compilation includes `lib` and `ui` only
> - When build is run with `--serverless` option, the typescript compilation includes `lib` and `serverless` only

Till now this guide explained the main concepts and project structure in the SOMOD module. In the [next chapter](/reference/main-concepts/extensions), let us understand how to extend the capabilities of SOMOD using extensions.
