What are the pros and cons of using the Yii Framework?

Let us have a closer look at the advantages and disadvantages of Yii for software development.

The benefits of using Yii framework development services

  • MVC(Model-View-Controller) design pattern. This means that you won’t have to develop every single module and they will be created automatically.
  • Yii supports layered data caching, fragment caching, page caching, and dynamic content, which helps reduce response time and speed up web application performance.
  • It uses different security measures to prevent websites from attacks such as SQL injection, cross-site request forgery (CSRF), cookie tampering, and cross-site scripting (CSS)
  • The framework provides tools for automation tasks like CRUD and model generators using Gii. It lets you create files for Create, Read, Update and Delete (CRUD) automatically.
  • Bootstrap CSS comes out-of-the-box when you install Yii.
  • Yii framework is easy to install by downloading a zip package, with no composer needed.
  • Yii allows for the use of third-party interfaces if you merge different frameworks with it. You can use code from PEAR or Zend in it.
  • The framework is supported by a large community of Yii developers.

The disadvantages of the Yii framework

And now, let’s look at the drawbacks of using Yii for your software development project.

  • Ajax features are sometimes not well documented, so you might need to dive into JavaScript code or ask JavaScript developers for help.
  • AR doesn’t support some doctrines such as AR queries.
  • Yii depends on static methods and many software engineers stand against them.

As we can see, despite its drawbacks, the Yii framework has many advantages. It speeds up software development and simplifies the engineers’ work. At SECL Group, we have been using the Yii framework for a while. Based on our experience with it, we feel that it is a good choice to build scalable and high-performance products.

The very first step before you start searching for Yii software developers is to define your requirements for hiring candidates. They may include:

  • the number of developers you need
  • time you can spend on recruitment before the project starts
  • expected levels of experience
  • tech and non-tech skills you anticipate from candidates
  • budget for hiring each candidate.

Once you are good to go with all this stuff, you can start looking for suitable candidates.

The most popular way is to hire an engineer through a software development company that has Yii web development services in their tech stack, which means you can hire experienced engineers who have already completed real projects using this technology.
