Also, all the spaces and new lines have been removed. If you notice, the buyFoodfunction is now called b. For example, we have a simple JavaScript code below: function buyFood() b() Obfuscation is the process of transforming your code which makes it hard for people to read and understand. There are several techniques you can use to make your client-side more secure. Using Third-Party Libraries and/or Components with Existing Vulnerabilitiesįor an in depth explanation on any of these vulnerabilities, I recommend visiting this article.Some of the most common client side vulnerabilities are: What Are Some JavaScript Client-Side Vulnerabilities Examples? Regardless of whether it is JavaScript, Python, C#, Ruby on Rails, or any other programming language, a vulnerability is the state of an application being exposed to attacks that could lead to harmful consequences such as unauthorized access, stolen data, or complete deletion of data. Should I Worry About Making The Client-Side Safer If The Server-Side is Already Secure? What Is A JavaScript Vulnerability?.Is The Server-Side More Secure Than The Client-Side?.Secure Frontend Can Still Be Vulnerable To Attacks.What Are Some JavaScript Client-Side Vulnerabilities Examples?.

It is important to understand how software development works and have a basic understanding of the risks involved not only on the client-side but also on the server-side. On the other hand, if developers lack the knowledge and skills to prevent vulnerabilities, the possibilities of having a hackable frontend system increase exponentially. Therefore, if the developer is experienced and constantly introducing best practices to make an application more secure on the client side, the likelihood of suffering from attacks will be reduced.
The main reason is that the security is dependent on the developer’s expertise in security.
Those with advanced skills can have access to critical information on the frontend and expose vulnerabilities.Īlthough it is not possible to achieve 100% protection, some applications are more secure than others.

The main reason is that there is no full control of the client-side as it is executed in the browser. In short, JavaScript client-side applications are not 100% safe. However, is the JavaScript Client-Side Secure? With more advances on the client-side, the level of responsibility has increased equally on both ends. Prior to the development of Frontend JavaScript frameworks, multiple projects relied on the backend, including its security. Software Development has evolved dramatically over the last 10+ years.
