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 52 | 53 | ## License 54 | 55 | Licensed under either of 56 | 57 | * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) 58 | * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) 59 | 60 | at your option. 61 | 62 | ### Contribution 63 | 64 | Unless you explicitly state otherwise, any contribution intentionally 65 | submitted for inclusion in the work by you, as defined in the Apache-2.0 66 | license, shall be dual licensed as above, without any additional terms or 67 | conditions. 68 | -------------------------------------------------------------------------------- /.travis.yml: -------------------------------------------------------------------------------- 1 | language: rust 2 | sudo: false 3 | 4 | cache: cargo 5 | 6 | matrix: 7 | include: 8 | 9 | # Builds with wasm-pack. 10 | - rust: beta 11 | env: RUST_BACKTRACE=1 12 | addons: 13 | firefox: latest 14 | chrome: stable 15 | before_script: 16 | - (test -x $HOME/.cargo/bin/cargo-install-update || cargo install cargo-update) 17 | - (test -x $HOME/.cargo/bin/cargo-generate || cargo install --vers "^0.2" cargo-generate) 18 | - cargo install-update -a 19 | - curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh -s -- -f 20 | script: 21 | - cargo generate --git . --name testing 22 | # Having a broken Cargo.toml (in that it has curlies in fields) anywhere 23 | # in any of our parent dirs is problematic. 24 | - mv Cargo.toml Cargo.toml.tmpl 25 | - cd testing 26 | - wasm-pack build 27 | - wasm-pack test --chrome --firefox --headless 28 | 29 | # Builds on nightly. 30 | - rust: nightly 31 | env: RUST_BACKTRACE=1 32 | before_script: 33 | - (test -x $HOME/.cargo/bin/cargo-install-update || cargo install cargo-update) 34 | - (test -x $HOME/.cargo/bin/cargo-generate || cargo install --vers "^0.2" cargo-generate) 35 | - cargo install-update -a 36 | - rustup target add wasm32-unknown-unknown 37 | script: 38 | - cargo generate --git . --name testing 39 | - mv Cargo.toml Cargo.toml.tmpl 40 | - cd testing 41 | - cargo check 42 | - cargo check --target wasm32-unknown-unknown 43 | - cargo check --no-default-features 44 | - cargo check --target wasm32-unknown-unknown --no-default-features 45 | - cargo check --no-default-features --features console_error_panic_hook 46 | - cargo check --target wasm32-unknown-unknown --no-default-features --features console_error_panic_hook 47 | - cargo check --no-default-features --features "console_error_panic_hook wee_alloc" 48 | - cargo check --target wasm32-unknown-unknown --no-default-features --features "console_error_panic_hook wee_alloc" 49 | 50 | # Builds on beta. 51 | - rust: beta 52 | env: RUST_BACKTRACE=1 53 | before_script: 54 | - (test -x $HOME/.cargo/bin/cargo-install-update || cargo install cargo-update) 55 | - (test -x $HOME/.cargo/bin/cargo-generate || cargo install --vers "^0.2" cargo-generate) 56 | - cargo install-update -a 57 | - rustup target add wasm32-unknown-unknown 58 | script: 59 | - cargo generate --git . --name testing 60 | - mv Cargo.toml Cargo.toml.tmpl 61 | - cd testing 62 | - cargo check 63 | - cargo check --target wasm32-unknown-unknown 64 | - cargo check --no-default-features 65 | - cargo check --target wasm32-unknown-unknown --no-default-features 66 | - cargo check --no-default-features --features console_error_panic_hook 67 | - cargo check --target wasm32-unknown-unknown --no-default-features --features console_error_panic_hook 68 | # Note: no enabling the `wee_alloc` feature here because it requires 69 | # nightly for now. 70 | -------------------------------------------------------------------------------- /LICENSE_APACHE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
