  47 +
  48 + "Contribution" shall mean any work of authorship, including
  49 + the original version of the Work and any modifications or additions
  50 + to that Work or Derivative Works thereof, that is intentionally
  51 + submitted to Licensor for inclusion in the Work by the copyright owner
  52 + or by an individual or Legal Entity authorized to submit on behalf of
  53 + the copyright owner. For the purposes of this definition, "submitted"
  54 + means any form of electronic, verbal, or written communication sent
  55 + to the Licensor or its representatives, including but not limited to
  56 + communication on electronic mailing lists, source code control systems,
  57 + and issue tracking systems that are managed by, or on behalf of, the
  58 + Licensor for the purpose of discussing and improving the Work, but
  59 + excluding communication that is conspicuously marked or otherwise
  60 + designated in writing by the copyright owner as "Not a Contribution."
  61 +
  62 + "Contributor" shall mean Licensor and any individual or Legal Entity
  63 + on behalf of whom a Contribution has been received by Licensor and
  64 + subsequently incorporated within the Work.
  65 +
  66 +2. Grant of Copyright License. Subject to the terms and conditions of
  67 + this License, each Contributor hereby grants to You a perpetual,
  68 + worldwide, non-exclusive, no-charge, royalty-free, irrevocable
  69 + copyright license to reproduce, prepare Derivative Works of,
  70 + publicly display, publicly perform, sublicense, and distribute the
  71 + Work and such Derivative Works in Source or Object form.
  72 +
  73 +3. Grant of Patent License. Subject to the terms and conditions of
  74 + this License, each Contributor hereby grants to You a perpetual,
  75 + worldwide, non-exclusive, no-charge, royalty-free, irrevocable
  76 + (except as stated in this section) patent license to make, have made,
  77 + use, offer to sell, sell, import, and otherwise transfer the Work,
  78 + where such license applies only to those patent claims licensable
  79 + by such Contributor that are necessarily infringed by their
  80 + Contribution(s) alone or by combination of their Contribution(s)
  81 + with the Work to which such Contribution(s) was submitted. If You
  82 + institute patent litigation against any entity (including a
  83 + cross-claim or counterclaim in a lawsuit) alleging that the Work
  84 + or a Contribution incorporated within the Work constitutes direct
  85 + or contributory patent infringement, then any patent licenses
  86 + granted to You under this License for that Work shall terminate
  87 + as of the date such litigation is filed.
  88 +
  89 +4. Redistribution. You may reproduce and distribute copies of the
  90 + Work or Derivative Works thereof in any medium, with or without
  91 + modifications, and in Source or Object form, provided that You
  92 + meet the following conditions:
  93 +
  94 + (a) You must give any other recipients of the Work or
  95 + Derivative Works a copy of this License; and
  96 +
  97 + (b) You must cause any modified files to carry prominent notices
  98 + stating that You changed the files; and
  99 +
  100 + (c) You must retain, in the Source form of any Derivative Works
  101 + that You distribute, all copyright, patent, trademark, and
  102 + attribution notices from the Source form of the Work,
  103 + excluding those notices that do not pertain to any part of
  104 + the Derivative Works; and
  105 +
  106 + (d) If the Work includes a "NOTICE" text file as part of its
  107 + distribution, then any Derivative Works that You distribute must
  108 + include a readable copy of the attribution notices contained
  109 + within such NOTICE file, excluding those notices that do not
  110 + pertain to any part of the Derivative Works, in at least one
  111 + of the following places: within a NOTICE text file distributed
  112 + as part of the Derivative Works; within the Source form or
  113 + documentation, if provided along with the Derivative Works; or,
  114 + within a display generated by the Derivative Works, if and
  115 + wherever such third-party notices normally appear. The contents
  116 + of the NOTICE file are for informational purposes only and
  117 + do not modify the License. You may add Your own attribution
  118 + notices within Derivative Works that You distribute, alongside
  119 + or as an addendum to the NOTICE text from the Work, provided
  120 + that such additional attribution notices cannot be construed
  121 + as modifying the License.
  122 +
  123 + You may add Your own copyright statement to Your modifications and
  124 + may provide additional or different license terms and conditions
  125 + for use, reproduction, or distribution of Your modifications, or
  126 + for any such Derivative Works as a whole, provided Your use,
  127 + reproduction, and distribution of the Work otherwise complies with
  128 + the conditions stated in this License.
  129 +
  130 +5. Submission of Contributions. Unless You explicitly state otherwise,
  131 + any Contribution intentionally submitted for inclusion in the Work
  132 + by You to the Licensor shall be under the terms and conditions of
  133 + this License, without any additional terms or conditions.
  134 + Notwithstanding the above, nothing herein shall supersede or modify
  135 + the terms of any separate license agreement you may have executed
  136 + with Licensor regarding such Contributions.
  137 +
  138 +6. Trademarks. This License does not grant permission to use the trade
  139 + names, trademarks, service marks, or product names of the Licensor,
  140 + except as required for reasonable and customary use in describing the
  141 + origin of the Work and reproducing the content of the NOTICE file.
  142 +
  143 +7. Disclaimer of Warranty. Unless required by applicable law or
  144 + agreed to in writing, Licensor provides the Work (and each
  145 + Contributor provides its Contributions) on an "AS IS" BASIS,
  146 + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
  147 + implied, including, without limitation, any warranties or conditions
  148 + of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
  149 + PARTICULAR PURPOSE. You are solely responsible for determining the
  150 + appropriateness of using or redistributing the Work and assume any
  151 + risks associated with Your exercise of permissions under this License.
  152 +
  153 +8. Limitation of Liability. In no event and under no legal theory,
  154 + whether in tort (including negligence), contract, or otherwise,
  155 + unless required by applicable law (such as deliberate and grossly
  156 + negligent acts) or agreed to in writing, shall any Contributor be
  157 + liable to You for damages, including any direct, indirect, special,
  158 + incidental, or consequential damages of any character arising as a
  159 + result of this License or out of the use or inability to use the
  160 + Work (including but not limited to damages for loss of goodwill,
  161 + work stoppage, computer failure or malfunction, or any and all
  162 + other commercial damages or losses), even if such Contributor
  163 + has been advised of the possibility of such damages.
  164 +
  165 +9. Accepting Warranty or Additional Liability. While redistributing
  166 + the Work or Derivative Works thereof, You may choose to offer,
  167 + and charge a fee for, acceptance of support, warranty, indemnity,
  168 + or other liability obligations and/or rights consistent with this
  169 + License. However, in accepting such obligations, You may act only
  170 + on Your own behalf and on Your sole responsibility, not on behalf
  171 + of any other Contributor, and only if You agree to indemnify,
  172 + defend, and hold each Contributor harmless for any liability
  173 + incurred by, or claims asserted against, such Contributor by reason
  174 + of your accepting any such warranty or additional liability.

  19 +
  20 +## About
  21 +
  22 +This template is designed for depending on NPM packages that contain
  23 +Rust-generated WebAssembly and using them to create a Website.
  24 +
  25 +* Want to create an NPM package with Rust and WebAssembly? [Check out
  26 + `wasm-pack-template`.](https://github.com/rustwasm/wasm-pack-template)
  27 +* Want to make a monorepo-style Website without publishing to NPM? Check out
  28 + [`rust-webpack-template`](https://github.com/rustwasm/rust-webpack-template)
  29 + and/or
  30 + [`rust-parcel-template`](https://github.com/rustwasm/rust-parcel-template).
  31 +
  32 +## 🚴 Usage
  33 +
  34 +```
  35 +npm init wasm-app
  36 +```
  37 +
  38 +## 🔋 Batteries Included
  39 +
  40 +- `.gitignore`: ignores `node_modules`
  41 +- `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
  42 +- `README.md`: the file you are reading now!
  43 +- `index.html`: a bare bones html document that includes the webpack bundle
  44 +- `index.js`: example js file with a comment showing how to import and use a wasm pkg
  45 +- `package.json` and `package-lock.json`:
  46 + - pulls in devDependencies for using webpack:
  47 + - [`webpack`](https://www.npmjs.com/package/webpack)
  48 + - [`webpack-cli`](https://www.npmjs.com/package/webpack-cli)
  49 + - [`webpack-dev-server`](https://www.npmjs.com/package/webpack-dev-server)
  50 + - defines a `start` script to run `webpack-dev-server`
  51 +- `webpack.config.js`: configuration file for bundling your js with webpack
