## Via tsconfig.json (recommended)

`ts-node` automatically finds and loads `tsconfig.json`. Most `ts-node` options can be specified in a `"ts-node"` object using their programmatic, camelCase names. We recommend this because it works even when you cannot pass CLI flags, such as `node --require ts-node/register` and when using shebangs.

ts-node works by registering hooks for `.ts`, `.tsx`, `.js`, and/or `.jsx` extensions.

Vanilla `node` loads `.js` by reading code from disk and executing it. Our hook runs in the middle, transforming code from TypeScript to JavaScript and passing the result to `node` for execution. This transformation will respect your `tsconfig.json` as if you had compiled via `tsc`.

### `TSError`

Type errors from the compiler are thrown as a `TSError`. These are the same as errors you get from `tsc`.

### `SyntaxError`

Any error that is not a `TSError` is from node.js (e.g. `SyntaxError`), and cannot be fixed by TypeScript or `ts-node`. These are bugs in your code or configuration.

**TypeScript Node** does _not_ use `files`, `include` or `exclude`, by default. This is because a large majority projects do not use all of the files in a project directory (e.g. `Gulpfile.ts`, runtime vs tests) and parsing every file for types slows startup time. Instead, `ts-node` starts with the script file (e.g. `ts-node index.ts`) and TypeScript resolves dependencies based on imports and references.

Instead, ts-node starts with the script file (e.g. `ts-node index.ts`) and TypeScript resolves dependencies based on imports and references.

For global definitions, you can use the `typeRoots` compiler option. This requires that your type definitions be structured as type packages (not loose TypeScript definition files). More details on how this works can be found in the [TypeScript Handbook](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#types-typeroots-and-types).
