institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

<h1><code>create-wasm-app</code></h1>
<strong>An <code>npm init</code> template for kick starting a project that uses NPM packages containing Rust-generated WebAssembly and bundles them with Webpack.</strong>
<p>
<a href="https://travis-ci.org/rustwasm/create-wasm-app"><img src="https://img.shields.io/travis/rustwasm/create-wasm-app.svg?style=flat-square" alt="Build Status" /></a>

</h3>
<sub>Built with 🦀🕸 by <a href="https://rustwasm.github.io/">The Rust and WebAssembly Working Group</a></sub>
</div>
## About
This template is designed for depending on NPM packages that contain
Rust-generated WebAssembly and using them to create a Website.
* Want to create an NPM package with Rust and WebAssembly? [Check out
`wasm-pack-template`.](https://github.com/rustwasm/wasm-pack-template)
* Want to make a monorepo-style Website without publishing to NPM? Check out
[`rust-webpack-template`](https://github.com/rustwasm/rust-webpack-template)
and/or
[`rust-parcel-template`](https://github.com/rustwasm/rust-parcel-template).
## 🚴 Usage
```
npm init wasm-app
```
## 🔋 Batteries Included
- `.gitignore`: ignores `node_modules`
- `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
- `README.md`: the file you are reading now!
- `index.html`: a bare bones html document that includes the webpack bundle
- `index.js`: example js file with a comment showing how to import and use a wasm pkg
- `package.json` and `package-lock.json`:
- pulls in devDependencies for using webpack:
- [`webpack`](https://www.npmjs.com/package/webpack)
- [`webpack-cli`](https://www.npmjs.com/package/webpack-cli)
- [`webpack-dev-server`](https://www.npmjs.com/package/webpack-dev-server)
- defines a `start` script to run `webpack-dev-server`
- `webpack.config.js`: configuration file for bundling your js with webpack
