Bazel: Open-Source Build & Test Tool
An open-source build and test tool optimized for large, multi-language software projects, incrementally building only changed components
What is Bazel?
Bazel is an open-source build and test automation tool maintained by Google. It is designed for building large-scale, multi-language software projects efficiently and quickly by only rebuilding what needs to be changed after code changes.
Some key features of Bazel include:
- Incremental builds - Bazel tracks code dependencies and builds only what needs to be rebuilt, speeding up the build process significantly for large projects.
- Scalable - Bazel distributes builds across multiple machines, allowing very large projects to be built quickly.
- Language agnostic - Bazel supports multiple programming languages like Java, C++, Python, Go, etc.
- Extensible and customizable - Users can write custom build rules and plugins to extend Bazel.
- Reproducible builds - Bazel guarantees reproducible builds by precisely tracking all inputs and dependencies.
- Large ecosystem of rules - Bazel comes with 700+ predefined rules for common languages and build processes.
Bazel is used by large companies like Google, Pinterest, Stripe, Dropbox for building critical production software efficiently and reliably.
