Regular Expression Worker

Execute Regular Expression Matches on a Node Worker Thread or in a Web Worker.

Regular Expressions can suffer from Catastrophic Backtracking. A very simple expression like /(x+x+)+y/ can cause your JavaScript application to freeze. This library allows you to run these expressions on another thread. If they take to long to complete, they are terminated, protecting your application from locking up.

Installation

npm install regexp-worker

Basic Usage

In the example below:

1. a new Worker thread is created
2. the regular expression is executed on the thread
3. the result is returned
4. the thread is stopped

For the occasional request, this is the easiest way, but the Worker startup and shutdown is expensive.
