## Usage
|
|
|
|
### Programmatic
|
|
|
|
```js
|

const jiti = require("jiti")(__filename);
|
|
|
|
jiti("./path/to/file.ts");
|
|
```
|
|
|
|
You can also pass options as second argument:
|
|
|
|
```js
|
|
const jiti = require("jiti")(__filename, { debug: true });
|
|
```
|
|
|
|
### CLI

node -r jiti/register index.ts
