@polkadot/wasm-schnorrkel

A fork of @parity/schnorrkel-js that allows proper operation against all the environments that the @polkadot/api supports. Changes from the base repo -

• WASM initialisation is done async, via Promise (this allows for clear operation in webpack environments without additional workers)
• WASM outputs are optimised via wasm-opt from the binaryen project
• Output bundle is wrapped with camelCase names (not including the __*** internal functions)
• Full named functions and parameter TypeScript definitions
• Requires for crypto is wrapped, removing "on-demand-require" warnings in webpack environment
• WASM output is done via a base-64 encoded string, supporting both Node.js and browser environments
• Extensive code cleanups and addition of functions required for all sr25519 operations
• Extended tests to cover Rust, wasm (via Node) and wasm (via jest), remove (here unused) www interfaces
• TextDecoder is polyfilled by using the version from @polkadot/util (consistent support, alos on React Native)
• Polyfill for crypto functions that are not available in some environments (e.g. Jest & React Native)

development

1. Build can be done via ./build.sh
2. Tests can be done via ./test.sh

future work

Support asm.js for environments (like React Native) that doesn't have WASM support. Initial attempts made at this, but not active.
