Vite 原始碼解讀: Dependency Pre-Bundling part 1

In this article, we will take a look at the Dependency Pre-Bundling feature in Vite’s source code and understand how it works.

Understanding Dependency Pre-Bundling

Dependency Pre-Bundling is a feature in Vite that aims to improve the performance of the build process by analyzing and pre-bundling dependencies. This helps in reducing the time it takes to build and bundle the application, especially when there are a large number of dependencies. The feature ensures that only the necessary dependencies are bundled, leading to faster build times and more efficient use of resources.

How it works

The Dependency Pre-Bundling feature works by analyzing the import statements in the code and identifying the dependencies that are used. It then pre-bundles these dependencies so that they can be quickly accessed during the build process. This helps in reducing the overall build time and improving the performance of the application.

Conclusion

Dependency Pre-Bundling is an important feature in Vite’s source code that helps in improving the build performance of applications. By analyzing and pre-bundling dependencies, it ensures that only the necessary code is bundled, leading to faster build times and more efficient use of resources. In the next part of this series, we will take a closer look at the implementation of this feature in Vite’s source code.
