wasm-pack

Unlike other tools, wasm-pack forces you to use a lib, not a bin crate, and the entry-point to your program is annotated with a #[wasm_bindgen(start)] attribute.

Your Cargo.toml also should specify that your crate's type is a "cdylib".

[package]
name = "yew-app"
version = "0.1.0"
authors = ["Yew App Developer <name@example.com>"]
edition = "2018"

[lib]
# You should include "rlib" (the default crate type) otherwise your crate can't be used as a Rust library
# which, among other things, breaks unit testing
crate-type = ["rlib", "cdylib"]

[dependencies]
# for web_sys
yew = "0.17"
# or for stdweb
# yew = { version = "0.17", package = "yew-stdweb" }
wasm-bindgen = "0.2"
