Conduct a review
Conduct a written project review that will guide making future decisions. before negotiating cooperation, we knew to deal with codebases that were written more than seven years ago and developed and maintained by a lot of people. The major things suggested reviewing the codebases. It outlined the main project characteristics and its potential flaws.
Once the test suite was built, started building all-new features thorough the TDD step, which established that the test suite was updated. By utilizing this process to ensure that the new features that I added pre-existing functionality, this process called regression testing.
This technique is the fastest way to write tests on existing code, so you can refactor it safely. refactoring code and optimizing performance or readability in a legacy codebase, which is done in a much more controlled way with proper documentation and tests, and can end up saving the company time and money through faster development, or use of fewer resources.
In many legacy applications, you’ll run into duplicate code that causes several errors as make one change in multiple places in the codebase because of this issue. An example of this was how the application working on dealt with view templates and many views files with identical HTML code.
Challenges of overcoming legacy project
Limited access and permission
Certainly, we had a lot of trouble with permissions to access some parts of the collaboration tools, design files, external links on task descriptions, and others.
Once you worked with an legacy project, you become grateful for things you sometimes take for granted for this case, localization-related tasks were the most time consuming because the client didn’t use any localization management tools, the fact that their apps support 13 languages didn’t work in our favor. For localization purposes, we developed a tool called Polyglot. The idea has all application strings in one place and shares between them all platforms.
The blog of taking over a legacy project is important to understand, not only the reason for being prepared for what steps you need to take to work on a legacy app but also you will have a better idea of build applications from scratch. Then back to the Eventbrite application was easy to work with and add features to name because it built from day one using each of the techniques. The above opportunities do not exist for the work you are doing on the legacy codebase would communicate that your career growth is negatively affected by the work, and otherwise ask for additional work, or to be moved somewhere else entirely.
