Unresolved dependencies & Missing global variable name when trying to import #mapbox/mapbox-gl-geocoder - node-modules

Question

I'm beginning with Svelte and I would like to (more or less) reproduce Mapbox store locator tutorial with Svelte & rollup. (Starting from svelte REPL starter kit).
Everything's fine for loading a map and some markers, but as soon as I try to import this package https://github.com/mapbox/mapbox-gl-geocoder, nothing works anymore and I'm not familiar enough with Svelte to figure out how to setup rollup and fix it.
<script>
import { onMount, setContext } from 'svelte'
import mapbox from 'mapbox-gl/dist/mapbox-gl.js';
import MapboxGeocoder from '#mapbox/mapbox-gl-geocoder'; // <<--- Problem here
mapbox.accessToken = 'xxx';
let map;
let geocoder;
onMount(() => {
map = new mapbox.Map({,,,});
geocoder = new MapboxGeocoder({,,,});
});
</script>
terminal :
bundles src/main.js → public/build/bundle.js...
(!) Missing shims for Node.js built-ins

events (imported by node_modules/#mapbox/mapbox-gl-geocoder/lib/index.js, events?commonjs-external)
(!) Missing global variable name
Use output.globals to specify browser global variable names corresponding to external modules
events (guessing 'events$1')
created public/build/bundle.js in 2s
browser console :
Uncaught ReferenceError: events$1 is not defined
at main.js:5
Then, I tried to add to my rollup config resolve and polyfills plugins, but have other errors.
rollup.config.js
import svelte from 'rollup-plugin-svelte';
import resolve from '#rollup/plugin-node-resolve';
import commonjs from '#rollup/plugin-commonjs';
import livereload from 'rollup-plugin-livereload';
import { terser } from 'rollup-plugin-terser';
import preprocess from 'svelte-preprocess';
import nodeResolve from '#rollup/plugin-node-resolve';
import nodePolyfills from 'rollup-plugin-node-polyfills';
const production = !process.env.ROLLUP_WATCH;
export default {
input: 'src/main.js',
output: {
sourcemap: true,
format: 'iife',
name: 'app',
file: 'public/build/bundle.js'
},
plugins: [
nodeResolve(),
nodePolyfills(),
svelte({
// enable run-time checks when not in production
dev: !production,
// we'll extract any component CSS out into
// a separate file - better for performance
css: css => {
css.write('bundle.css');
},
preprocess: preprocess()
}),
// If you have external dependencies installed from
// npm, you'll most likely need these plugins. In
// some cases you'll need additional configuration -
// consult the documentation for details:
// https://github.com/rollup/plugins/tree/master/packages/commonjs
resolve({
browser: true,
dedupe: ['svelte']
}),
commonjs(),
// In dev mode, call `npm run start` once
// the bundle has been generated
!production && serve(),
// Watch the `public` directory and refresh the
// browser on changes when not in production
!production && livereload('public'),
// If we're building for production (npm run build
// instead of npm run dev), minify
production && terser()
],
watch: {
clearScreen: false
}
};
function serve() {
let started = false;
return {
writeBundle() {
if (!started) {
started = true;
require('child_process').spawn('npm', ['run', 'start', '--', '--dev'], {
stdio: ['ignore', 'inherit', 'inherit'],
shell: true
});
}
}
};
}
Gives me this
bundles src/main.js → public/build/bundle.js...
LiveReload enabled
(!) `this` has been rewritten to `undefined`

165: }(this));

to conclude: I'm a bit lost :D
thanks in advance
