Serving frontend from Rust

We now know that we can serve our React application if we can serve a HTML file that can point to the bundle.js file. Of course we can do this using a Rust server. To achieve this, we can create an ingress workspace with the following directory layout:

ingress
    ├── Cargo.toml
    ├── frontend
    │   ├── esbuild.js
    │   ├── package.json
    │   ├── serve.json
    │   ├── public

    │   │   └── index.html
    │   └── src
    │       └── index.tsx
    └── src
        └── main.rs

Here we can see that the server in the ingress/src/main.rs file is going...
