Using plugin serve with watch option

I’m not sure if I’m using this incorrectly or it is a “bug”. I’m trying to use this plugin with the watch option. The first time it runs ok, It looks like the socket is kept open. The second time I run the build it reports the port is already in use.

It only happens while using the watch option but it is completely fine without it.

Here is my rollup.config.js

import commonjs from "rollup-plugin-commonjs";
import resolve from "rollup-plugin-node-resolve";
import babel from "rollup-plugin-babel";
import uglify from "rollup-plugin-uglify";
import serve from "rollup-plugin-serve";
import livereload from "rollup-plugin-livereload";


const DISTFOLDER = "dist";

export default {
    entry: "src/main.js",
    format: "iife",
    moduleName: "app",
    plugins: [
        resolve({ jsnext: true, main: true }),
        commonjs(),
        babel({ exclude: "node_modules/**" }),
        uglify(),
        serve({ contentBase: DISTFOLDER,  port: 8080 }),
        livereload({ watch: DISTFOLDER })
    ],
    external: [],
    dest: `${DISTFOLDER}/bundle.js`
};

What’s the holdup for releasing this to npm?

Thanks for reporting 😃

I’m not sure how to fix it. PRs welcome!
