esbuild-c

esbuild-c (v0.1.37) enhances esbuild with config processing capabilities: aligning CLI options with the JS API, supporting config merging via 'extends', and loading configs in various formats (JSON, YAML, JS, TS) using cosmiconfig. As a PoC, it addresses esbuild issue #884 (CLI plugin specification) and offers both CLI and programmatic usage. It requires esbuild >=0.19.0 and ships TypeScript types. Unlike alternatives like esbuild-config or esbuild-resolve-config, it focuses on extendable config merging and format flexibility.
