+# super-regex
+
+> Make a regular expression time out if it takes too long to execute
+
+This can be used to prevent [ReDoS vulnerabilities](https://en.wikipedia.org/wiki/ReDoS) when running a regular expression against untrusted user input.
+
+This package also has a better API than the built-in regular expression methods. For example, none of the methods mutate the regex.
+
+The timeout only works in Node.js. In the browser, it will simply not time out.
+
+## Install
+
+```sh
+npm install super-regex
+```
+
+## Usage
+
+```js
+import {isMatch} from 'super-regex';
+
+console.log(isMatch(/\d+/, getUserInput(), {timeout: 1000}));
+```
+
+## API
+
+### isMatch(regex, string, options?)
+
+Returns a boolean for whether the given `regex` matches the given `string`.
+
+If the regex takes longer to match than the given timeout, it returns `false`.
+
+*This method is similar to [`RegExp#test`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/test), but differs in that the given `regex` is [never mutated, even when it has the `/g` flag](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/test#using_test_on_a_regex_with_the_global_flag).*
+
+### firstMatch(regex, string, options?)
+
+Returns the first `Match` or `undefined` if there was no match.
+
+If the regex takes longer to match than the given timeout, it returns `undefined`.
+
+### matches(regex, string, options?)
+
+Returns an iterable of `Match`es.
+
+If the regex takes longer to match than the given timeout, it returns an empty array.
+
+**The `regex` must have the `/g` flag.**
+
+#### options
+
+Type: `object`
+
+##### timeout?
+
+Type: `number` *(integer)*
+
+The time in milliseconds to wait before timing out.
+
+##### matchTimeout?
+
+Type: `number` *(integer)*
+
+Only works in `matches()`.
+
+The time in milliseconds to wait before timing out when searching for each match.
+
+### Match
+
+```ts
+{
+	match: string;
+	index: number;
+	groups: string[];
+	namedGroups: {string: string}; // object with string values
+	input: string;
+}
+```
