12/23/2023 0 Comments Appcode bazelGoogle’s Bazel build tool is emerging as the leading solution for fast and correct large-scale software build automation. The latter was confirmed explicitly in the 1.0 release announcement. As a result, you can expect bug fixes, new features, and long-term support. Moreover, with Bazel’s move to go open source, it’s also backed by a dedicated team of Google developers. One of the biggest advantages to using Bazel is that Google is driving it, which means that the project benefits from years of in-house use and evolution at Google. ![]() With the help of Bazel’s extension mechanism, called rules, developers can enhance the tool’s base functionality and share it across the organization or wider community. While Bazel’s built-in support for languages and ecosystems is broad and expansive, it cannot cover every possible use case. It’s not uncommon for projects to have custom requirements. Furthermore, Bazel embraces modern software development methodologies like containerization of applications with Docker and deployment to orchestration engines like Kubernetes. For example, it supports the JVM (Java Virtual Machine) ecosystem, native languages, and JavaScript. Many build tools support building only a single language or ecosystem. Build execution can be performed on a single machine or distributed across multiple remote machines (e.g., located in a datacenter). Improvements to build performance become more apparent in larger codebases, as Bazel can execute its work in parallel and in a distributed fashion. Bazel can handle both code organizational structures quite well. That’s common practice, especially if you are working on software with a microservices architecture. It’s not a dealbreaker if you break down your projects into individual source code repositories. Bazel ensures a sandboxed build execution by enforcing the definition of all of its dependencies explicitly.īazel’s main focus is on projects with large codebases, predominantly for organizations that have decided to put all of their projects into a monorepo. Nondeterministic behavior erodes trust in the correctness of build results. When executing builds over and over again, you do not want any surprises. Needless to say, you can still fine-tune the compiler or linker settings if needed. Instead, you just point your build to the source code and declare dependencies. As a result, you do not have to concern yourself with low-level implementation details like compilers or linkers. ![]() ![]() Starlark introduces an abstraction to the concepts of a build and hides its implementation complexities as much as possible. Why should I use Bazel?Īs a developer of build logic, you use a higher-level language called Starlark, a Python derivative. Bazel supports large codebases across multiple repositories, and large numbers of users. Bazel supports projects in multiple languages and builds outputs for multiple platforms. It uses a human-readable, high-level build language. < Back to Blog Accelerating Bazel CI/CD Pipeline Performance for Autonomous Vehicles Shailesh Manjrekar.īazel is an open-source build and test tool similar to Make, Maven, and Gradle.
