-# napi
-
-This directory contains source for Deno's Node-API implementation. It depends on
-`napi_sym` and `deno_napi`.
-
-Files are generally organized the same as in Node.js's implementation to ease in
-ensuring compatibility.
-
-## Adding a new function
-
-Add the symbol name to
-[`cli/napi_sym/symbol_exports.json`](../napi_sym/symbol_exports.json).
-
-```diff
-{
-  "symbols": [
-    ...
-    "napi_get_undefined",
--   "napi_get_null"
-+   "napi_get_null",
-+   "napi_get_boolean"
-  ]
-}
-```
-
-Determine where to place the implementation. `napi_get_boolean` is related to JS
-values so we will place it in `js_native_api.rs`. If something is not clear,
-just create a new file module.
-
-See [`napi_sym`](../napi_sym/) for writing the implementation:
-
-```rust
-#[napi_sym::napi_sym]
-pub fn napi_get_boolean(
-  env: *mut Env,
-  value: bool,
-  result: *mut napi_value,
-) -> Result {
-  // ...
-  Ok(())
-}
-```
-
-Update the generated symbol lists using the script:
-
-```
-deno run --allow-write tools/napi/generate_symbols_lists.js
-```
-
-Add a test in [`/tests/napi`](../../tests/napi/). You can also refer to Node.js
-test suite for Node-API.
-
-```js
-// tests/napi/boolean_test.js
-import { assertEquals, loadTestLibrary } from "./common.js";
-const lib = loadTestLibrary();
-Deno.test("napi get boolean", function () {
-  assertEquals(lib.test_get_boolean(true), true);
-  assertEquals(lib.test_get_boolean(false), false);
-});
-```
-
-```rust
-// tests/napi/src/boolean.rs
-
-use napi_sys::Status::napi_ok;
-use napi_sys::ValueType::napi_boolean;
-use napi_sys::*;
-

-  assert_eq!(argc, 1);
-
-  let mut ty = -1;
-  assert!(unsafe { napi_typeof(env, args[0], &mut ty) } == napi_ok);
-  assert_eq!(ty, napi_boolean);
-
-  // Use napi_get_boolean here...
-
-  value
-}
-
-pub fn init(env: napi_env, exports: napi_value) {
-  let properties = &[crate::new_property!(env, "test_boolean\0", test_boolean)];
-
-  unsafe {
-    napi_define_properties(env, exports, properties.len(), properties.as_ptr())
-  };
-}
-```
-
-```diff
-// tests/napi/src/lib.rs
-
-+ mod boolean;
-
-...
-
-#[no_mangle]
-unsafe extern "C" fn napi_register_module_v1(
-  env: napi_env,
-  exports: napi_value,
-) -> napi_value {
-  ...
-+ boolean::init(env, exports);
-
-  exports
-}
-```
-
-Run the test using `cargo test -p tests/napi`.
