FOR ANYONE WHO IS GOING THROUGH THE STEPS IN 'Hello, World' AND HAS ERRORS

Run the following code instead:

cargo generate --git https://github.com/rustwasm/wasm-pack-template # Type wasm-game-of-life

and then

cd wasm-game-of-life
wasm-pack build
npm init wasm-app www
# Fix dependencies. We will first install sd to make replacing text easier and cross-platform and rusty.
cargo install sd
sd '  "devDependencies": \{
    "hello-wasm-pack": "\^0.1.0",
    "webpack": "\^4.29.3",
    "webpack-cli": "\^3.1.0",
    "webpack-dev-server": "\^3.1.5",
    "copy-webpack-plugin": "\^5.0.0"
  \}' ' "dependencies": {
    "wasm-game-of-life": "file:../pkg"
  },
  "devDependencies": {
    "copy-webpack-plugin": "^11.0.0",
    "hello-wasm-pack": "^0.1.0",
    "webpack": "^5.90.0",
    "webpack-cli": "^5.1.4",
    "webpack-dev-server": "^4.15.1"
  }' www/package.json
cd www
rm package-lock.json
npm install
# Fix webpack config
sd -F "new CopyWebpackPlugin(['index.html'])" 'new CopyWebpackPlugin({ patterns: ["index.html"] })' webpack.config.js
sd '^\}' '  experiments: { asyncWebAssembly: true },\n}' webpack.config.js
npm run start

This should work in bash. In zsh you can just run it all at once for some reason

Thanks for this, was really helpful.

I was still having issues with this but I changed the devDependencies in package.json to this:

  "devDependencies": {
    "copy-webpack-plugin": "^11.0.0",
    "hello-wasm-pack": "^0.1.0",
    "webpack": "^5.88.1",
    "webpack-cli": "^5.1.4",
    "webpack-dev-server": "^4.15.1"
  }

and that fixed it.

@magnus-ISU, did you PR the wasm-pack-template?

I got an error at this line:

npm init wasm-app www

The error:

The work-around (from #169) is apparently to run this instead:

cargo generate --git https://github.com/rustwasm/create-wasm-app  # type "www" at the prompt
