deno_json_op

This is a crate for easing the building of deno plugins by providing a simple macro which automatically converts the first element in the ZeroCopy to a serde_json::Value and the Result<_, _> to a json object.

Usage

use deno_core::error::AnyError;

use deno_core::plugin_api::Interface;
use deno_core::plugin_api::Op;
use deno_core::plugin_api::ZeroCopyBuf;

use deno_core::serde_json::Value;
use deno_core::serde_json::json;

use deno_json_op::json_op;

#[no_mangle]
pub fn deno_plugin_init(interface: &mut dyn Interface) {
  interface.register_op("test", op_test);
}

#[json_op]
fn op_test(_interface: &mut dyn Interface, val: Value, _zero_copy: &mut [ZeroCopyBuf]) -> Result<Value, AnyError> {
  Ok(json!({
    "hello": val
  }))
}
