nodejs napi module did not self register - node.js

Question

when i try to test nodejs N-API modules, the has a error to me:
my addon.c file is that:
#include <node_api.h>
napi_value HelloMethod (napi_env env, napi_callback_info info) {
napi_value world;
napi_create_string_utf8(env, "world", 5, &world);
return world;
}
void Init (napi_env env, napi_value exports, napi_value module, void* priv) {
napi_property_descriptor desc = { "hello", 0, HelloMethod, 0, 0, 0, napi_default, 0 };
napi_define_properties(env, exports, 1, &desc);
}
NAPI_MODULE(NODE_GYP_MODULE_NAME, Init)
my binding.gyp file is:
{
"targets": [
{
"target_name": "addon",
"source": ["addon.c"]
}
]
}
and when i use require('./build/Release/addon') to call addon modules, the error info is :
Error: Module did not self-register.

Answer 1

It seems the newer versions of node-addon-api has changed its API for the module registration/export. The data types that you are using will not work anymore either.
It is now done like so
#include <napi.h>
Napi::String HelloMethod(const Napi::CallbackInfo& info) {
Napi::Env env = info.Env();
return Napi::String::New(env, "world");
}
Napi::Object Init(Napi::Env env, Napi::Object exports) {
exports.Set(Napi::String::New(env, "hello"),
Napi::Function::New(env, HelloMethod));
return exports;
}
NODE_API_MODULE(addon, Init)
This works on node 11.10.1 and node-addon-api 1.6.2.

Try to change the file name "addon.c" to "addon.cpp", then rebuild and run.
See this: Successful compiling the Node module and "Module did not self-register."
