+
+> Memoize the results of a call to the RegExp constructor, avoiding repetitious runtime compilation of the same string and options, resulting in suprising performance improvements.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install regex-cache --save
+```
+
+* Read [what this does](#what-this-does).
+* See [the benchmarks](#benchmarks)
+
+## Usage
+
+Wrap a function like this:
+
+```js
+var cache = require('regex-cache');
+var someRegex = cache(require('some-regex-lib'));
+```
+
+**Caching a regex**
+
+If you want to cache a regex after calling `new RegExp()`, or you're requiring a module that returns a regex, wrap it with a function first:
+
+```js
+var cache = require('regex-cache');
+
+function yourRegex(str, opts) {
+  // do stuff to str and opts
+  return new RegExp(str, opts.flags);
+}
+
+var regex = cache(yourRegex);
+```
+
+## Recommendations
+
+### Use this when...
+
+* **No options are passed** to the function that creates the regex. Regardless of how big or small the regex is, when zero options are passed, caching will be faster than not.
+* **A few options are passed**, and the values are primitives. The limited benchmarks I did show that caching is beneficial when up to 8 or 9 options are passed.
+
+### Do not use this when...
+
+* **The values of options are not primitives**. When non-primitives must be compared for equality, the time to compare the options is most likely as long or longer than the time to just create a new regex.
+
+### Example benchmarks
+
+Performance results, with and without regex-cache:
+
+```bash
+# no args passed (defaults)
+  with-cache x 8,699,231 ops/sec ±0.86% (93 runs sampled)
+  without-cache x 2,777,551 ops/sec ±0.63% (95 runs sampled)
+
+# string and six options passed
+  with-cache x 1,885,934 ops/sec ±0.80% (93 runs sampled)
+  without-cache x 1,256,893 ops/sec ±0.65% (97 runs sampled)
+
+# string only
+  with-cache x 7,723,256 ops/sec ±0.87% (92 runs sampled)
+  without-cache x 2,303,060 ops/sec ±0.47% (99 runs sampled)
+
+# one option passed
+  with-cache x 4,179,877 ops/sec ±0.53% (100 runs sampled)
+  without-cache x 2,198,422 ops/sec ±0.47% (95 runs sampled)
+
+# two options passed
+  with-cache x 3,256,222 ops/sec ±0.51% (99 runs sampled)
+  without-cache x 2,121,401 ops/sec ±0.79% (97 runs sampled)
+
+# six options passed
+  with-cache x 1,816,018 ops/sec ±1.08% (96 runs sampled)
+  without-cache x 1,157,176 ops/sec ±0.53% (100 runs sampled)
+
+# 
+# diminishing returns happen about here
+# 
+
+# ten options passed
+  with-cache x 1,210,598 ops/sec ±0.56% (92 runs sampled)
+  without-cache x 1,665,588 ops/sec ±1.07% (100 runs sampled)
+
+# twelve options passed
+  with-cache x 1,042,096 ops/sec ±0.68% (92 runs sampled)
+  without-cache x 1,389,414 ops/sec ±0.68% (97 runs sampled)
+
+# twenty options passed
+  with-cache x 661,125 ops/sec ±0.80% (93 runs sampled)
+  without-cache x 1,208,757 ops/sec ±0.65% (97 runs sampled)
+
+# 
+# when non-primitive values are compared
+# 
+
+# single value on the options is an object
+  with-cache x 1,398,313 ops/sec ±1.05% (95 runs sampled)
+  without-cache x 2,228,281 ops/sec ±0.56% (99 runs sampled)
+```
+
+## Run benchmarks
+
+Install dev dependencies:
+
+```bash
+npm i -d && npm run benchmarks
+```
+
+## What this does
+
+If you're using `new RegExp('foo')` instead of a regex literal, it's probably because you need to dyamically generate a regex based on user options or some other potentially changing factors.
+
+When your function creates a string based on user inputs and passes it to the `RegExp` constructor, regex-cache caches the results. The next time the function is called if the key of a cached regex matches the user input (or no input was given), the cached regex is returned, avoiding unnecessary runtime compilation.
+
+Using the RegExp constructor offers a lot of flexibility, but the runtime compilation comes at a price - it's slow. Not specifically because of the call to the RegExp constructor, but **because you have to build up the string before `new RegExp()` is even called**.
