> Escape RegExp special characters
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install escape-string-regexp
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const escapeStringRegexp = require('escape-string-regexp');
|
|
|
|
const escapedString = escapeStringRegexp('How much $ for a 🦄?');
|
|
//=> 'How much \\$ for a 🦄\\?'
|
|
|
|
new RegExp(escapedString);

You can also use this to escape a string that is inserted into the middle of a regex, for example, into a character class.
