quickjs-wasm-rs

High-level bindings and serializers for a Wasm build of QuickJS.

Bindings

Context corresponds to a QuickJS JSContext and Value corresponds to a QuickJS JSValue.

```rust use quickjswasmrs::Context;

let mut context = Context::default(); ```

will create a new context.

Serializers

This crate provides optional transcoding features for converting between serialization formats and Value: - messagepack provides quickjs_wasm_rs::messagepack for msgpack, using rmp_serde. - json provides quickjs_wasm_rs::json for JSON, using serde_json.

msgpack example:

```rust use quickjswasmrs::{messagepack, Context, Value};

let context = Context::default(); let inputbytes: &[u8] = ...; let inputvalue = messagepack::transcodeinput(&context, inputbytes).unwrap(); let outputvalue: Value = ...; let output = messagepack::transcodeoutput(output_value).unwrap(); ```

Building a project using this crate

• Install the wasi-sdk for your platform
• Set the QUICKJS_WASM_SYS_WASI_SDK_PATH environment variable to the absolute path where you installed the wasi-sdk

For example, if you install the wasi-sdk in /opt/wasi-sdk, you can run: bash export QUICKJS_WASM_SYS_WASI_SDK_PATH=/opt/wasi-sdk
