- Validation of Incomplete Input
Validating user input on both the server and client sides is an absolute must when it comes to web development! We’ve all heard the adage “don’t trust user input,” but errors caused by validation happen all too frequently. SQL Injection is one of the most significant repercussions of this error, appearing year after year in the OWASP Top 10. Keep in mind that most front-end programming frameworks include out-of-the-box validation procedures that are quite simple to employ. Furthermore, most major back-end programming platforms employ basic annotations to ensure that given data follows expected standards. Validation may take some time to establish, however it should be included in your usual coding approach and never overlooked.
- Incompatibility between Browsers
Most development procedures have a strict timeframe. As a result, developers typically utilise only one browser to test the programme while creating. That’s fine if you have time later to test it in different browsers and correct any errors. Evaluate your web app on different browsers. It is preferable to utilise a tool. If you don’t have such a time frame, it’s a good way to check the app in multiple browsers as it’s being developed. That is not a thing that can be overlooked. You must test your application in three main browsers, including Firefox, Microsoft Edge, and Chrome. There may be UI problems in Chrome that may not be present in Firefox. Aim to make your web applications cross-browser compatible as feasible. Avoid utilising browser-specific code, so please remember that majority of the time, cross-browser interoperable code exists.
- Neglecting Technical SEO
When it refers to SEO, developers are often pleased with the value of their meta-data, content, keywords, tags, layout, and so on. SEO, on the other hand, is far more than this. It entails removing duplication, having crawlable site architecture, clever backlinking, and a variety of other things. Several web developers believe that SEO is better left to content developers or marketers. Yet SEO must be implemented from the start to be effective. SEO is more than simply content and backlinks.
- Neglecting Web Standards
Web standards exist to help you integrate create and code device-independent applications. Web standards are there to help you, not to complicate your life. A rookie developer may make mistakes such as utilising unsuitable DOCTYPES (including transitional DOCTYPES), utilizing HTML that no longer applies (such as centre elements), not verifying code, or disregarding the outcomes. Give importance to web standards as well as operate around them to prevent errors and produce clean, error-free coding.
