webpack-spawn-plugin

A webpack plugin that runs child_process.spawn during compilation, useful for running shell commands or starting processes as part of the build pipeline. The latest stable version is 0.3.0, released infrequently with last update in 2018. It supports Webpack 4+ hooks via the 'when' option (default 'done') and offers a 'persistent' flag to avoid respawning on recompilation. Compared to alternatives like webpack-shell-plugin or webpack-exec-plugin, this one directly uses Node's spawn for more control over stdio and process handling.
