Best mistakes developers make in web programming
There are many mistakes that web developers must correct themselves to increase productivity. Today we have thousands of digital and printed resources that provide step-by-step instructions about developing all kinds of different web applications. Development environments are smart enough to catch and fix many mistakes that early developers battled with regularly. There are even many different development platforms that easily turn simple static HTML pages into highly interactive applications.
Incomplete input validation
Validating user input on client and server side is simply a must do! We are all aware of the sage advice “do not trust user input” but, nevertheless, mistakes stemming from validation happen all too often. One of the most common consequences of this mistake is SQL Injection which is in OWASP Top 10 year after year. Remember that most front-end development frameworks provide out-of-the-box validation rules that are incredibly simple to use. Additionally, most major back-end development platforms use simple annotations to assure that submitted data are adhering to expected rules. Implementing validation might be time consuming, but it should be part of your standard coding practice and never set aside.
Authentication without proper Authorization
Verifying that a person is (or at least appears to be) a specific user, since he/she has correctly provided their security credentials (password, answers to security questions, fingerprint scan, etc.). Confirming that a particular user has access to a specific resource or is granted permission to perform a particular action. Stated another way, authentication is knowing who an entity is, while authorization is knowing what a given entity can do.
Not ready to scale
In today’s world of high speed development, startup accelerators, and instant global reach of great ideas, having your MVP (Minimum Viable Product) out in the market as soon as possible is a common goal for many companies. However, this constant time pressure is causing even good web development teams to often overlook certain issues. Scaling is often one of those things teams take for granted. The MVP concept is great, but push it too far, and you’ll have serious problems. Unfortunately, selecting a scalable database and web server and separating all application layers on independent scalable servers is not enough. There are many details you need to think about if you wish to avoid rewriting significant parts of your application later – which becomes a major web development problem.
Wrong or missing SEO
The root cause of incorrect or missing SEO best practices on web sites is misinformed SEO specialists. Many web developers believe that they know enough about SEO and that it is not especially complex, but that’s just not true. SEO mastery requires significant time spent researching best practices and the ever-changing rules about how Google, Bing, and Yahoo index the web. Unless you constantly experiment and have accurate tracking + analysis, you are not a SEO specialist, and you should not claim to be one.
