// Single-threaded (non-shared-memory) WASI builds link an emnapi archive

// without the C async-work and threadsafe-function implementations (they are
|
|
// unconditional `napi_generic_failure` stubs without threads), so the
|
|
// generated loaders provide the JavaScript implementations through these
|
|
// plugins instead. Raw `instantiateNapiModule(Sync)` callers instantiating a
|
|
// single-threaded napi-rs wasm must pass them too:
|
|
// `plugins: [emnapiAsyncWorkPlugin, emnapiTSFNPlugin]` — without them
|
|
// instantiation fails with a LinkError naming the missing import. Threaded
|
|
// (shared-memory) builds link the C implementations and need no plugins;
|
|
// this mirrors the upstream @emnapi/core v2 plugin split (v1 bundled these
|
|
// implementations in the core runtime). The plugins are bundled into this
|
|
// package so loading the runtime with @emnapi/core v1 does not resolve the
|
|
// v2-only `@emnapi/core/plugins` package export.
