``sh`
npm install @contentauth/c2pa-wasm
Ensure the repo-wide prerequisites NX and pnpm are installed.
Then, all of the following prerequisites must be installed before c2pa-wasm can be built:
#### Rust
Minimum supported Rust version: 1.86.0.
Additionally, the wasm32-unknown-unknown target must be installed:
`sh`
rustup target add wasm32-unknown-unknown
#### wasm-bindgen-cli
`sh`
cargo install wasm-bindgen-cli@0.2.106
#### wasm-pack
`sh`
cargo install wasm-pack@0.13.1
To build the library:
`sh`
nx build c2pa-wasm
This will execute the commands defined in the nx-wasm-bindgen executor to produce the final output in the pkg/ directory.
The library relies on wasm-pack to run its tests. As a general principle, the majority of test coverage will come from c2pa-web's test suite.
To run the tests:
`
nx test c2pa-wasm
