Universal Library

This is a universal library written in rust that builds into wasm.
The library is called universal_lib.wasm and can be used in any environment that supports wasm.

How to build

First make sure rustup is using the wasm32-wasi compile target

rustup target add wasm32-wasi

Run the following command to build the library and generate a new .wasm file.

cargo build --target=wasm32-wasi

If there are no compile errors, the new version of the library should be built into the path: target/wasm32-wasi/debug/universal_lib.wasm.

The wasm executable can be referenced under the above mentioned path by projects willing to consume the library.

You can inspect the generated executable using the wasmer inspect command:

wasmer inspect universal_lib.wasm

How to publish

Make sure wasmer is installed.

The cargo wasmer utility can be used to publish a new version of the package to the webassembly registry.

cargo wasmer --dry-run

This will generate all the uploadable artefacts in target/wasmer.

Rerunning the command without the --dry-run flag will build the project and upload the artefacts to the webassembly registry.
