JavaScript Security , or JS for short, is a vital piece of web development. But one downside to all the good that it can do is how open-ended and unpredictable it often is. It seems like there’s always something new to learn about this language. You could be working diligently on your project and suddenly find yourself learning about a security flaw for the first time or needing to update your code after finding an exploit in an external dependency you were unaware of.
Source Code Is Open Source
The code in your project is readily available on GitHub, Bitbucket, or any other server of your choice. You can link directly to it from your browser and are fully responsible for it. You will, of course, want to rectify all errors in your code as soon as possible but this is not so you have to do a security review first. You do it because you want the latest version of the code in order to fix mistakes.
JavaScript Security Is A Team Effort
You cannot do anything about javascript security issues that affect your project alone. Other members of your team should be involved in fixing such issues.
JavaScript Engenders Collaboration
Within your project, you will have contributors who will be able to fix bugs and help with maintenance. Fortunately, there’s a lot you can do to make JavaScript safer and more predictable. In this article, I will review the top ten benefits of JavaScript security and how to use them to make your projects a lot more reliable. Here are some key points.
JavaScript Encourages Community Involvement
Appsealing JS open source communities where people share information and learn about new fixes for old problems. You should make use of these resources as they can really make a difference to your project.
JavaScript Is Easy To Learn
The syntax is straightforward and it’s easy to find tutorials that will help you learn more about JS. This feature really helps with finding contributors – especially if you are looking for someone to work on a security update.
6. JavaScript Runs In Many Browsers
If a new bug comes up, you only have one browser to test against. There’s no need to use different operating systems or try out different versions of browsers – all of which can be rather time-consuming.
Security Updates Are Easy To Implement
You don’t have to retrofit security mechanisms into the code. You can simply make the bug fixes and the new functions you need. There are plenty of guides that will show you how to make this part of your project easier.
JavaScript Is Open Source
All of the source code is available on GitHub, most of it with detailed documentation and code comments as well as a directory structure that makes it easy to find related projects.
JavaScript Is Versatile
The language has many uses that can all be accessed via a single link. It’s important to note that the same item in a different section of the site may require a different code for it to function properly. This makes it necessary for you to have good knowledge of what your project needs and who will be using it – so as to prevent security breaches.
JavaScript Is Dynamic
Just like the title says, JS is dynamic. It’s a language that goes with the flow, capable of changing its behavior to suit your needs. If you want your project to be flexible, then this is exactly what you need.
End web applications
Using JavaScript and Node.js, you can build rich, modularized applications that run in the browser, on a server, and even on both at the same time. In this article, we’ll focus on building modules for front-end web applications, with Node.js as the backend platform. This type of architecture is surprisingly efficient and easy to implement, even for a beginner.
Get Familiar With Node.js
Node.js was developed by Ryan Dahl in 2009, and its popularity has been growing ever since. It’s an open-source, asynchronous I/O framework that runs on Google Chrome’s JavaScript engine and is widely used to develop software applications using Javascript on the server-side.
At its core, Node.js is a platform that allows you to write JavaScript code using the “module” approach of encapsulating code into a single unit. Gone are the days when you had to create a whole new function every time you wanted to perform an action on your web application; Node.js can handle many of these problems for you. In fact, there’s a whole ecosystem of modules available that can be easily installed in your project. In this article, we’ll use several open-source modules like:
– Express – a toolkit for building a web application with Node.js
– Mongoose – a flexible MongoDB Object Model
– AngularJS – JavaScript MVC Framework
Get Node Up And Running
If you’ve never used Node.js before, you can easily get started by installing the module on your system using the instructions available here. By installing it on GitHub, you’ll be able to receive updates directly from the source (and not from a third party).
Once installed, update your package list and start using Node.js by typing “npm” on a terminal.

Create The Server
We’ll be using Express as our main module for creating the server that will host our application. To install it, use the “npm install express” command on your terminal. This will create a folder named “node_modules” in your root directory. This is where all packages are kept if you decide to install them without specifying a specific location (through the -g <location> flag). Install the package using the “npm install express” command:
Conclusion
Create The Base DirectoryNext, create a folder named “server” within your current directory. This is where you’ll be placing all your modules together with the Express application file (a program file). Use the following command to create this folder: Acknowledging that we have a valid copy of Node.js installed on our system, we can now create the Express application using the “express” command.
