JScrambler Now Compliant with Node.js

JScrambler is now compliant with Node.js. This tool makes developer code harder to read (and to potentially maliciously manipulate), and has been updated with a self-protection feature. Created under the vision of Portuguese startup CEO Rui Ribeiro, JScrambler provides a means for software application developers to obfuscate their source code one individual file at a time — or a whole project at once. The software works for both mobile and desktop web applications and is supplied as a web-based service.

JScrambler 3.5 introduced self-defending capabilities to HTML5 and JavaScript applications. It uses source code obfuscation techniques to transform code into a completely garbled format. On top of that, it installs a number of different code traps that gives code tools to protect it. For instance, it can make code detect tampering and break down on purpose.

Obviously, not everyone will feel the need to protect his or her code, admits Ribeiro. But if you are doing serious things with JavaScript, this could be interesting. JScrambler claims to be the "only full stack JavaScript protection solution" and the only one that supports Node.js.

With Node.js, JavaScript can be used outside the context of a web browser, both on the server and client sides. It can also be built outside the browser and later be packed and executed inside the browser. This flexibility and elegance surely contributed to its popularity.

However, whether you're working on a library distributed through NPM, a standalone client or a browser application, and like regular web applications developed using JavaScript, it is still sent or installed in clear-text in the end-user device. If you are using shared or hosted servers, you may be worried to know that your code is stored in clear-text," said Ribeiro.

The new release, version 3.6, was fully tested with Node.js related libs such as Express.js, Koa, and Socket.io. Plus, it ships with a Node.js API client, with wrappers for Grunt and Gulp task runners, and a convenient plugin for the Github's Atom edition.

Whether you build your application using a command-line script or a task runner, the firm says it's very easy to integrate JScrambler in your existing building process. JScrambler is already integrated in all major task runners and if that does not work for you, they have a JScrambler API CLI executable that you can all from your scripts or your favorite IDE. There's also a Node.js API client.

From now on you can minify and optimize your JavaScript applications with JScrambler for free — because minification and optimization are industry standards which you can get from JScrambler using the web application Interface or integrating it in your build process using our Web API and one of the ready to use API clients.
