- The author describes their journey to build the Bun JavaScript toolkit without its usual binary dependencies.
- Initial challenges included the lack of packaged versions of Bun and OpenCode for their Linux distribution.
- Bun's build process assumes the Bun CLI is already available, complicating bootstrapping.
- The author created a wrapper script to log and fulfill Bun's build dependencies using alternative tools.
- Bun's build scripts rely on Bun for package management, TypeScript runtime, and bundling.
- Alternative tools like npm, Node.js, and esbuild were used to replace Bun's functionalities.
- Challenges included adapting Bun's private Zig compiler features and fixing bundling errors.
- A working bootstrapped Bun binary was successfully built and used to run OpenCode.
- The author submitted an RFC to the Bun team for potential upstream integration of their changes.
- The project highlights the importance of building from source and understanding dependencies.
