# babel-code-frame
> Generate errors that contain a code frame that point to source locations.
## Install
```sh
npm install --save-dev babel-code-frame
```
## Usage
```js
import codeFrame from 'babel-code-frame';
const rawLines = `class Foo {
constructor()
}`;
const lineNumber = 2;
const colNumber = 16;
const result = codeFrame(rawLines, lineNumber, colNumber, { /* options */ });
console.log(result);
```
```sh
1 | class Foo {
> 2 | constructor()
| ^
3 | }
```
If the column number is not known, you may pass `null` instead.
## Options
### `highlightCode`
`boolean`, defaults to `false`.
Toggles syntax highlighting the code as JavaScript for terminals.
### `linesAbove`
`number`, defaults to `2`.
Adjust the number of lines to show above the error.
### `linesBelow`
`number`, defaults to `3`.
Adjust the number of lines to show below the error.
### `forceColor`
`boolean`, defaults to `false`.
Enable this to forcibly syntax highlight the code as JavaScript (for non-terminals); overrides `highlightCode`.
