The article explores the synergy between Bazel and Gazelle in building and developing Go applications, emphasizing their ability to streamline and automate the build process. Bazel, an open-source build system by Google, excels in handling fast and incremental builds through advanced caching, making it suitable for complex projects with multiple languages. Gazelle complements Bazel by automatically generating build files, particularly for Golang projects. The tutorial guides readers through setting up a workspace, running tests, and developing a basic application using these tools, highlighting how they reduce build times by only recompiling changed code. However, it also notes that Bazel and Gazelle can introduce complexity, especially for smaller projects, where Earthly offers a simpler alternative. Earthly aims to make build processes more accessible by minimizing setup and promoting best practices, thereby catering to both small and large projects with less complexity.
