Yew-template
My setup for web development with Yew.
Based on yew-wasm-pack-template.
How to use
Make sure you installed rust, wasm-pack, and npm or yarn.
(I recommend to use yarn for its speed)
1. Install dependency
yarn install
2. Development
Start development server on localhost:8080. It watches source file changes and rebuild automatically.
yarn dev
3. Production build
Make production build to dist folder.
yarn build
Selecting Optimization Options
To reduce wasm file size, There are some optimization options.
I wanted to know its effects, so I took benchmark. Here is the results.
(I didn't check its speed, size only. Used rustc 1.43.0.)
| Production Build | Development Build | |
|---|---|---|
| No Options | 84.5 KiB | 750 KiB |
| LTO | 86.4 KiB | 763 KiB |
| opt-level = s | 76.8 KiB | 131 KiB |
| opt-level = z | 81.3 KiB | 157 KiB |
| LTO + opt-level = s | 76.4 KiB | 129 KiB |
| LTO + opt-level = z | 81.3 Kib | 156 KiB |
Graph
"No Options" and "LTO" on development build isn't on here because they're too big and prevents see differences.
So this template is using "LTO + opt-level = s" which is smallest output size on production build.
If you want to change this option, see cargo.toml file.
