Is there any impact if uniapp does not use sass?

With the continuous development of front-end technology, more and more frameworks and technologies are applied to mobile terminal development. Among them, uni-app is a cross-platform development framework that has attracted much attention in recent years. In the development of uni-app, we usually use CSS precompilers such as less or sass to write styles to improve development efficiency and code maintainability. But will there be any impact on development if I don’t use Sass? This article will explore this issue.

1. What is Sass?

Sass (Syntactically Awesome Style Sheets) is a CSS precompiler that allows us to write CSS in a way similar to writing scripts. Sass has similar syntax to CSS, but provides more functions and options, and can better organize and manage style sheets, greatly improving the maintainability of CSS.

2. uni-app combines the advantages of Sass

In uni-app, using Sass can bring many benefits, such as:

(1) Unified management of variables: Through the variable mechanism of Sass, you can use a variable to define colors, fonts, spacing, etc., and can uniformly manage the styles of different components or pages.

(2) Nested rules: Using Sass, we can group nested CSS rules, which greatly reduces the complexity of the code and can express the structure and relationship of styles more clearly.

(3) Mixin and inheritance: Sass can create reusable code blocks through the mixin and inheritance mechanism, which again reduces the complexity of the code and improves the maintainability of the code.

(4) Modular development: Through Sass’s file division and modular development, the styles of each component or page can be better organized and managed, making the code more readable and maintainable.

3. The impact of not using Sass on uni-app

Although Sass has many advantages, if you do not use Sass, it will not produce much in the development of uni-app Influence. We can manually define variables, classes, IDs, selectors, etc. in CSS. Although the code is scattered, not using Sass will not bring much burden to development.

However, the disadvantages of not using Sass are also obvious:

(1) High code complexity: without Sass’s nesting and Mixin mechanism, you need to manually write CSS selectors, which results in The amount of code is large and the readability is poor.

(2) Styles are not easy to maintain: Without Sass’s file segmentation and modularization mechanism, you would need to manually find and modify styles in a large number of CSS files, which would waste developers’ time and energy.

In summary, although not using Sass will not have much impact on the development of uni-app, in actual development, using Sass is still a very convenient and effective way. Especially in large projects, using Sass can better organize and manage styles, improving code readability and maintainability. Therefore, we should use Sass as much as possible and consider how to make reasonable use of Sass's various features before starting the project.
