xBuildBuild, type-check, and serve TypeScript projects

xBuild v1 is an esbuild-powered toolchain with lifecycle hooks, conditional code inclusion, and a built-in dev server.

🧠
TypeScript tooling
Type checking and `.d.ts` generation with `declaration`, `bundleDeclaration`, and `--typeCheck`.
⚙️
esbuild under the hood
Bundling, minification, and format control through the `esbuild` options block.
🪝
Lifecycle hooks
Tap into the build with `onStart`, `onResolve`, `onLoad`, `onEnd`, and `onSuccess`.
🔌
Conditional code
Strip code blocks and `$$`-prefixed functions at build time with `ifdef` and `define`.
🔁
Dev workflow
Watch mode, Node.js dev runner, and an HTTP/HTTPS server for the build output.
🧩
Programmatic API
Drive builds from code with `build`, `buildWithConfigPath`, and `buildWithArgv`.
