So, what important technical details you should consider before make your website live?

  • Make sure that your website works reasonably well across all major browsers, because sometimes browsers implement standards inconsistently. Also, consider how browsers render your website in various operating systems, and how people might use the website other than from major browsers.
  • Ensure that you deploy updates on the websites without affecting the users. Have staging environments(one or more tests) available to implement changes on the websites, such as modifying architecture, adding content, changing code, etc., and ensure that they are deployed carefully without affecting anything else in the website. So, always have an automated way of deploying changes to the live website.
  • Never display unfriendly errors straight away to the users of the website. Also, never provide the user’s email ID in plain text as it may get spammed to death.
  • Learn how doing progressive enhancement, which helps you to deliver the best possible experience to the users.
  • Always REDIRECT after a POST if it was done successfully. This helps you to prevent a refresh from submitting again.
  • Make sure that you take accessibility into account without fail. Because, in certain situation, it is a legal requirement.
  • Aware about Injections like SQL injection, and learn how to prevent them. You have to use hash passwords to prevent rainbow attacks.
  • Use SSL/HTTPS for pages like login pages or the pages where sensitive data is entered.
  • Avoid cross site scripting (XSS) and cross site request forgeries (CSRF). Also, prevent session hijacking and Clickjacking.
  • Implement caching if necessary. To do this, you have to use HTTP caching and HTML5 Manifest properly.
  • Learn how to deflate content and optimize images in the website.
  • To reduce the number of browser connections, try to compress duplications among files by improving gzip ability.
  • For performance profiling, use Google page speed with browser extension. This helps to optimize images in the website. You can use CSS Image Sprites for small related images like toolbars.
  • Reduce the number of HTTP requests that are required for a browser to render the web page.

  • To load frameworks, consider using a service like Google Libraries API. This makes a browser to use a copy of the framework it has already cached instead of downloading a duplicate copy from your website.
  • Always set up a better error reporting solution, and document how the application works. Also, make frequent backups and make sure that the backups are functional.
  • Use a version control system that helps you to store your files. Also, never forget to do your acceptance testing.
  • Ensure that you have enough logging in place using frameworks. When logging, make sure that you capture both handled exceptions as well as unhandled exceptions. And analyze the log output regularly to find out the key issues in your website.
