No config, trunk, simple example

I will start with the documentation.

The yew framework documentation shows how to prepare a project step by step.

Build a sample app · Yew Docs

First create a new Rust library \(important: create a _library_, not a _binary_ by passing the `--lib` flag\):

yew.rs

In the next step we will convert the application to no config and use trunk.

thedodd/trunk

Trunk is a WASM web application bundler for Rust. Trunk uses a simple, zero-config pattern for building & bundling…

github.com

Installing the trunk program

cargo install trunk

cargo install wasm-bindgen-cli

Deleting the ‘static’ directory

rm -r ./static

create index.html in directory project

vi index.html<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title>Yew • Counter</title>
  </head>

  <body></body>
</html>

next steps

trunk build 

trunk clean

trunk config show

trunk watch

We make few changes and see how these changes are available immediately.

Conclusion

It seems to me that this is a good direction for creating small applications that run faster and are smaller than java-script programs after a certain code size threshold.
