How to build WASM

# build wasm English-Chinese dictionary
GOARCH=wasm GOOS=js go build -o dict_ec.wasm wasm_ec/main.go

# build wasm Chinese-English dictionary
GOARCH=wasm GOOS=js go build -o dict_ce.wasm wasm_ce/main.go

or just use the prebuilt wasm file from https://github.com/mojocn/wasmecdict/releases/download/v1.0.1/ecdict.wasm

        let wasm: WebAssembly.WebAssemblyInstantiatedSource;
        if ("instantiateStreaming" in WebAssembly) {
            wasm = await WebAssembly.instantiateStreaming(
                fetch(wasmUrl),
                go.importObject,
            );
        } else {
            const resp = await fetch(wasmUrl);
            const bytes = await resp.arrayBuffer();
            wasm = await WebAssembly.instantiate(bytes, go.importObject);
        }
        go.run(wasm.instance);
        return {

        } as EcDict;
    } catch (e) {
        console.error(e);
        return null;
    }
}

usage:

const wordInfo = window.ecLookUp('Awesome');
console.log(wordInfo);
