Rewriting my bot's dashboard, separating the backend into a /api path, and using Vue.js for the front-end.

Well now I explain the thing

npm i -g @vue/cli

Go to the frontend folder.

Install front-end dependencies with npm i

Run npm run build or vue-cli-service build.

npm i

Soon an example of it.

npm start

If you chose SERVESTATIC='true', then just point to the correct port on your favorite web server.

Otherwise configure your server to always serve index.html from the public folder, and the paths with /api to the backend.

See Caddyfile for an example on the Caddy web server.
