  • wit-bindgen

    A language binding generator for WebAssembly interface types

  • Yes, wasm_bindgen is js only. At least for now, in future I would also expect it to migrate to component model. There is also cargo-component which is a way to create modules compatible with component model. You define your module interface in WIT and your dependencies on other wasm modules in the similar way you would define crate dependencies. Alternately there is wit-bindgen that is a codegen tool for multiple languages that also accepts WIT as input.

  • component-model

    Repository for design and specification of the Component Model

  • It may be not the answer you want depending on your time restrictions but I also tried doing the same and currently just waiting for wasm component model proposal to be finished.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • cargo-component

    A Cargo subcommand for creating WebAssembly components based on the component model proposal.

  • Yes, wasm_bindgen is js only. At least for now, in future I would also expect it to migrate to component model. There is also cargo-component which is a way to create modules compatible with component model.

  • wasmtime

    A fast and secure runtime for WebAssembly

  • The only runtime that at least partially implements component model is wasmtime. But, as everything with component model, it is still WIP.

  • fp-bindgen

    Bindings generator for full-stack WASM plugins

  • Yep, you're right. For this, there are a few options. The ones most relevant to you are fp-bindgen, which targets Wasmer, and wit-bindgen, which targets wasmtime.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
