+# 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.
+

+### `highlightCode`
+
+`boolean`, defaults to `false`.

+
+### `linesBelow`
+
+`number`, defaults to `3`.
+
+Adjust the number of lines to show below the error.
