Hello. Thank you for contacting.

esbuild-dev-server calling rebuild repeatedly with the same options.
esbuild requires incremental: true property in options for this.
Read more: https://esbuild.github.io/api/#incremental

Add this property to the options and try again.

const options = {
    entryPoints: ['src/app.tsx'],
    bundle: true,
    metafile: true, // needs to be set
    outdir: 'dist/', // needs to be set
    incremental: true, // !important
    plugins: [
        htmlPlugin(htmlPluginOptions),
        lessLoader()
    ],
    loader: {
        '.ts': 'ts',
    },
}

I get the same error, and I made sure to use incremetal: true

esBuildDevServer.start(build({
  sourcemap: true,
  entryPoints: ['src/index.tsx'],
  bundle: true,
  outdir: 'build',
  platform: 'browser',
  minify: true,
  keepNames: true,
  target: 'es6',
  plugins: [
    lessLoader(),
  ],
  metafile: true,
  incremental: true,
}), {
  port:      '3000',
  watchDir:  'src',
  index:     'build/index.html',
  staticDir: 'build',
})

This happens, because the server binary is not set as executable. Same happens in Linux. Manually making it executable works.

Looking at the makefile and the paths in it, you probably build on Unix-type OS or WSL, so you probably just need a chmod here and there in the makefile.

Indeed - running chmod u+x node_modules/esbuild-dev-server-darwin-x64/devserver as a patch till fixed
