Nicola Del Gobbo presented on developing Node.js native addons from scratch. Native addons allow integration of C/C++ code and libraries with Node.js for performance benefits. They can be loaded using require() but require special handling to interface with JavaScript. The presentation covered why to use native addons, how to structure a project, asynchronous programming, and interfacing with Node.js objects like EventEmitters and streams. Upcoming N-API will improve compatibility across Node.js versions and platforms.
Node.js Native AddOns from zero to hero - Nicola Del Gobbo - Codemotion Rome ...Codemotion
This talk is about creating Node.js interfaces for native libraries written in C or C++. It starts with various situations in which you need to build native addons and the common problems in doing that. I'll discuss the reference provided by the new N-API (Node-API) that helps mantainers to support a wide variety of Node.js releases without needing recompilation or abstraction layers. With all these tools and knowledge I'll show you how to build some addons from scratch and how to convert existing addons using the new N-API. The last part is related to future developments about addons.
Nativescript allows building native mobile apps using JavaScript and CSS. It works by injecting native APIs into JavaScript so they can be accessed directly. This allows using native UI controls and hardware capabilities while coding in a familiar language. Nativescript apps are compiled to platform-specific code, so they are true native apps that can be submitted to app stores. It supports Angular for building apps with common code shared across platforms.
JS Fest 2019/Autumn. Алексей Орленко. Node.js N-API for RustJSFestUA
This document discusses using the N-API in Rust to build native Node.js addons. N-API allows addons to work across Node.js versions without recompiling. The document outlines plans to get started with N-API in Rust, generate bindings from C headers, build a type-safe Rust API, use macros to reduce boilerplate, perform parallel computations, and benchmark performance. Resources are provided for following along with the code examples.
As modern, agile architects and developers we need to master several different languages and technologies all at once to build state-of-the-art solutions and yet be 100% productive. We define our development environments using Gradle. We implement our software in Java, Kotlin or another JVM based language. We use Groovy or Scala to test our code at different layers. We construct the build pipelines for our software using a Groovy DSL or JSON. We use YAML and Python to describe the infrastructure and the deployment for our applications. We document our architectures using AsciiDoc and JRuby. Welcome to Babel!
Making the right choices in the multitude of available languages and technologies is not easy. Randomly combining every hip technology out there will surely lead into chaos. What we need is a customized, streamlined tool chain and technology stack that fits the project, your team and the customer’s ecosystem all at once. This code intense, polyglot session is an opinionated journey into the modern era of software industrialization.
The world of Node native add-on development continues to rapidly evolve. After widespread adoption of N-API starting last year, the Node native add-on ecosystem is gaining momentum as the underlying technology and tools continue to advance.
This workshop, offered by experts from the N-API team, describes important new features essential to the performance of your native add-on. These new features include asynchronous operations which permit you to safely and reliably spread your work across multiple threads. Context awareness permits your add-on to be loaded multiple times without the multiple copies interfering with each other. Finally, adopting thread-safe functions insures your functions run reliably regardless of the thread from which they are called or in which they run.
Whether you are just starting out with native add-ons or are an old pro looking for an update on N-API, bring your project or work through the workshop tutorials under the helpful guidance of the N-API experts. You’ll leave this workshop with a solid understanding of these important new technologies and how they apply to your own projects. And perhaps, with a bit of luck, working code!

Kubernetes is a container-orchestration system for automating deployment, scaling, and operations of application containers across clusters of hosts. It was designed by Google and is now maintained by the Cloud Native Computing Foundation. Kubernetes allows containers to run seamlessly over multiple computing nodes like Docker Swarm. Helm charts package multiple related Kubernetes resources into a single installable unit and help manage dependencies between packages. The basic Kubernetes objects include pods, replica sets, deployments, services, ingress, config maps, secrets, and persistent volumes. Helm commands are used to install, upgrade, and manage packaged Kubernetes resources.
Presentation at Node Interactive 2017
Until now, native module (add-ons) maintainers have had to recompile for each Node.js release as well as potentially updating their code to cope with the rapid pace of changes in the v8 APIs. The community API working group has been developing the N-API (Node-API) as a follow on to Nan to help solve this problem and insulate modules from changes in the v8 APIs.
By targeting the new API, modules will be able support a wide variety of Node.js releases without needing recompilation or abstraction layers such as Nan - reducing deployment time and maintenance effort for both module developers and Node.js end users.
With an initial version of the API slated to be part of Node version 8 as an experimental feature, it is a good time to come learn about the shape and usage of the new API from those working to implement it.

API Design in the Modern Era - Architecture Next 2020Eran Stiller
APIs are at the heart of the modern software development world. Whether we author a distributed system, a microservices-based application, or a simple client-server n-tier application - our system will most probably expose an API at its core. APIs are a means to expose the functionality of a particular component to its users. Unsurprisingly, many formats for APIs have existed over the years, with the industry setting around RESTful APIs as the de-facto standard, with gRPC growing in popularity.
Join me in this session, as I review today's most popular API formats and their relative strengths and weaknesses. From REST, through OpenAPI, via gRPC and to the rising star of AsyncAPI - we'll explain how these API formats work and the tools they employ and offer some guidance as towards when we should use each. At the end of this session, you'll have a good familiarity with these formats, and you'll be in a much better position to choose between them.

This document discusses Istio, an open platform for connecting, managing, and securing microservices. It provides features like circuit breaking, fault injection, canary deployments, rate limiting, service metrics, tracing, and mutual TLS without requiring code changes. Istio uses interceptors and Mixer to enforce policies across traffic in a Kubernetes cluster. The document outlines some capabilities of Istio and also notes it is still in alpha stage with some known issues around documentation and debugging.
This document introduces CloudBridge, a Python library that provides a simple, uniform API for interacting with multiple cloud providers. It aims to allow users to write code once that can run on any supported cloud without specialization for individual providers. CloudBridge focuses on mature cloud APIs and offers a set of conformance tests to ensure compatibility without needing separate testing for each provider. The document outlines the goals, design, and features of CloudBridge, and provides code samples for setting up a provider and launching an instance using the uniform API.

N-API is a new stable C/C++ API for building native modules in Node.js that provides ABI compatibility across Node.js versions and platforms without requiring recompilation. It allows modules to be compiled once and run on multiple Node.js versions and platforms. Several major modules have already been ported to N-API including Node-Sass, Canvas, SQLite, LevelDown, and Nanomsg. The presenters encourage more native module maintainers to consider porting to help improve compatibility and reduce maintenance costs.
Until now, native module maintainers have had to recompile for each Node.js release as well as potentially updating their code to cope with the rapid pace of changes in the v8 APIs.

Confoo - Javascript Server Side : How to startQuentin Adam
nodeJS, claypool, APE, map reduce en nosql, yql... Le javascript server side est un sujet d'actualité, une tendance de fond est en train d'émerger. Et la mise en avant des outils dans la communauté progresse rapidement.
La promesse d'un seul langage sur le client et le serveur d'une application web est très attirante alors que HTML5, les websockets, les webworker, les local storage sont en train de se faire une place dans le futur du web.
Cette conférence a pour but de vous permettre de mieux appréhender cet écosystème à travers son historique, l'exposé des standards émergeant, des avantages et défauts des différentes solutions proposées et en présentant les briques communes.
Quels projets pouvez vous entreprendre sur ces technologies ?
Est-ce possible à intégrer en production ?
L'administration et l'intégration de ces outils au SI d'une entreprise est il possible ?
Ces technologies vont elles s'implanter ou rester des expérimentations de techniciens sous stéroïdes ?
Node.js is a server-side JavaScript environment that allows building scalable network applications. It uses Google Chrome's V8 JavaScript engine and runs on a single thread without blocking I/O operations. Node.js is optimized for non-blocking event-driven operations and has a large ecosystem of reusable modules. Some common uses of Node.js include real-time web applications, REST APIs, streaming data applications, and networking servers.
This document provides an overview of topics that will be covered at a Microsoft Dev Camp in 2015. The topics include introductions to ASP.NET, Visual Studio web tools, ASP.NET Web API, building real-time web applications with SignalR, and Azure services. Sessions will cover web front-end development, ASP.NET updates, consuming and building Web APIs, and real-world scenarios for scaling, updating, and deploying applications on Azure.
Node.js is an asynchronous event-driven JavaScript runtime that uses non-blocking I/O to build scalable network applications. It allows for the creation of web servers and networking tools using a event-driven, non-blocking I/O model rather than the traditional threaded model. Node.js is popular because it uses JavaScript and allows code reuse on both the server-side and client-side, offers high performance and scalability for real-time applications, and has a large passionate community supporting its use.
Unlike Node, which is a monolithic project, Deno is organized into a collection of Rust crates. I will summarize the history of why Ryan Dhal made this choice and what each crate is for. These include:

Based on Google's V8 JavaScript engine, NodeJS is a fairly new platform for creating scalable and real-time web applications. I will introduce you to NodeJS internals and ecosystem as well as exaplain why and how you can use Node in your Drupal based projects.
Exploring Next Generation Buildpacks - Anand Rao & Scott DeegVMware Tanzu
Cloud native buildpacks are pluggable, modular tools that translate source code into OCI container images. They provide portability, modularity, faster builds, and reproducible images. Buildpacks detect the application, define the build environment, and output the container image. They allow writing code and running apps with minimal effort. The demo will show buildpacks decomposing builds into groups and updating the OS layer for fast updates.
The document discusses .NET and its capabilities for building applications across platforms. It can be used as a system component on Windows, run on virtual machines, and be deployed with applications. Code can be edited in Visual Studio and compiled to native for each platform, allowing shared codebases while accessing native APIs and delivering high performance. This allows building applications with a single C# codebase that can target iOS, Windows, and Android with native UIs and shared logic.

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine that allows for writing server-side code in JavaScript. It has a single-threaded, event-driven architecture that makes it efficient for data-intensive real-time applications. Some key advantages of Node.js include using JavaScript for both client-side and server-side code, high performance due to event-driven and non-blocking model, and rich ecosystem of third-party modules. Mobile web apps can be built with Node.js by using HTML5 features and JavaScript on the server and client sides.
The document discusses native application development for Android. It covers using the Native Development Kit (NDK) to write parts of Android apps in native code like C/C++ for performance benefits. The key points are:
- Native code can provide speed improvements for tasks like signal processing but also increases complexity.
- Google's Bionic C library is used instead of glibc for size, speed and licensing reasons and has some differences like lacking C++ exceptions.
- The NDK allows building native code libraries and combining them with Java code via the Java Native Interface (JNI).
- Native code interfaces with Android via JNI and system headers while the build system handles toolchains.
The session is geared toward CTOs who want to evaluate React-Native for their existing and future apps. It will also be helpful for web/mobile developers who want to jump into React-Native.
Yann Rouillard presented principles for a developer-friendly CI/CD pipeline for Kubernetes applications. The principles include having a simple interface like a deployment file template, validating configuration early to fail fast, making the pipeline self-service through automation and templates, providing clear error messages with context, and ensuring the pipeline is troubleshoot-able by developers. Examples were given of implementing these principles using tools like Python scripts, Helm, schemas, and error tracking software. The talk concluded with a Q&A section and thanks to the audience.

3. What is Node.js Native Add-on?
C / C++ code called from JavaScript
BRIDGE
Native environment JavaScript
4. From Node.js documentation
Node.js Addons are dynamically-linked shared objects, written in
C++, that can be loaded into Node.js using the require() function,
and used just as if they were an ordinary Node.js module.
They are used primarily to provide an interface between JavaScript
running in Node.js and C/C++ libraries.
5. How is it possible?
All the magic is behind the Node.js architecture
6. Why?
Performance
In general C / C++ code performs better than
JavaScript code, but it’s not always true.
Image processing (in average 6 times faster)
Video processing
CRC cyclic redundancy check (in average 125 times faster)
Compression
Scientific calculus
Algorithms that execute CPU heavy tasks
8. Why?
You don’t find what fits your specific needs on npm
Sometimes completely implementing the module
in JavaScript is not the right solution
Think at libraries like:
ImageMagick
Ghostscript
FFmpeg
TensorFlow
…
9. Why?
Better error handling
Even if you will use an old C / C++ library you will get an
error code that explains the error that just happened
In new C / C++ library you have the exception
You don’t have to parse some string to identify if there
was an error and what kind of it
11. Problems
Fragmentation API
The API to implement native add-ons has been changed across
different version of Node.js
Most of the changes were on V8 API and ObjectWrap API
0.8 - 0.10.x - 0.12.x - 1.x - 2.x - 3.x - 4.x - 5.x - 6.x - 7.x - 8.x - 9.x
For more info http://v8docs.nodesource.com/
12. Problems
Need an adapter to stay compatible across different
version of Node.js
• NAN - Native Abstraction for Node.js
• API compatibility
• Strong bonded with V8 API
• You have to recompile your native add-ons switching to
different version of Node.js
14. Problems
Write portable C / C++ code
Your native code must compile and run on different:
ARCHITECTURE PLATFORM COMPILER
15. Problems
Documentation
• C / C++ libraries that you are integrating are not well documented
• There are good references but not so much practical guide
focusing on complex concepts about native add-ons
16. N-API
N-API will be a game changer on the native add-on
development
• API and ABI compatibility
• Isolated from V8 (VM agnostic)
• New ES6 types
• C / C++ (only header wrapper)
• Conversion tool that helps to migrate from NAN
• Generator (helps with initial scaffolding)
• Pre-builds (node-pre-gyp - prebuildify)
31. • ObjectWrap is a way to expose your C++ code to JavaScript
• You have to extend ObjectWrap class that includes the plumbing to
connect JavaScript code to a C++ object
• Classes extending ObjectWrap can be instantiated from JavaScript
using the new operator, and their methods can be directly invoked
from JavaScript
• Unfortunately, the wrap part really refers to a way to group methods and
state
• It’s your responsibility write custom code to bridge each of your C++
class methods.
ObjectWrap API
32. Much of the Node.js core API modules are built aroud an idiomatic asynchronous
event-driven architecture in which certains kinds of objects (called emitter)
periodically emit named events that cause Function objects ("listeners") to be
called.
• Emit event from C++
• Implement a native add-on object that inherits from Event Emitter
Event Emitter
33. See the example here
https://github.com/NickNaso/conf-cd-rome-2018/tree/master/04-addon-
event-emitter
34. A stream is an abstract interface for working with streaming data in Node.js.
The stream module provides a base API that makes it easy to build objects
that implement the stream interface.
Using Transform stream to pass and get back data from a native add-on
Stream
35. See the example here
https://github.com/NickNaso/conf-cd-rome-2018/tree/master/05-addon-
stream
36. • Create simple interface between C / C++ and JavaScript
• Think carefully at JavaScript interface
• Use ObjectWrap API to return C / C++ object to JavaScript
• Validate the types on the native side
• Expose only the functionalities you need
• Don’t block the event loop, stay asynchronous: this is a
must if you will use the add-ons in high performance services
• Use Buffer to pass big quantity of data
Lessons learned
37. • The largest number of native add-ons is written using NAN
• N-API will be go out of experimental very soon
• Backports for 8.x
• Backports for 6.x
• Documentation for node-addon-api
• Porting preexistentes native addon-ons to N-API
• Investigate how to use prebuild with N-API
Present and future
38. Implement key value database
Binding to Vedis an embeddable datastore C library
Good afternoon everyone. Thank you to attend my talk, today I’m very honored to be here and share my ideas with all of you.
My name is Nicola Del Gobbo and I’m developer at Packly. In my every day work I take care of building Packly’s backend systems. In my spare time I try to give my contribution to all frameworks, libraries and modules that I use in my work and obviously I like creating new one. Today the talk is focused on Node.js native addon start with its definition.
In a very simple way Native Addons could be considered as C / C++ code called from JavaScript. They are a bridge between our Application programming language JavaScript and Native environment that is completely written in C / C++. This allow us to call C / C++ functions and methods directly from JavaScript.
If we take a look at Node.js documentation under Addons section Native Addons are defined as: dynamically-linked shared objects, written in C++, that can be loaded into Node.js using the require() function, and used just as if they were an ordinary Node.js module
Their main purpose is to provide an interface between JavaScript running in Node.js and C / C++ libraries.
This increase the developer experience because if you are using a Native Addon you don’t care of this, but you just use it as any other pure JavaScript module.
How is it possible?
All the magic is behind the Node.js architecture.
Node.js is built on some C / C++ libraries the most important for us as native addon developers are V8 and libuv.
V8 is a JavaScript engine that take care to compile JavaScript code, execute it and give us great performance.
Through the V8 APIs we can create function, object and do almost everything that we do on the JavaScript side.
Libuv is a high performance evented I/O library and has the responsibility to handle the event loop (our main thread) and all the asynchronous tasks.
Why should you implement new Native Add-On?
The first reason is for performance
In general C / C++ code performs better then JavaScript code, but it’s really true for CPU bounds operations.
Think for example at:
Image processing | Video processing | Compression | Scientific calculus | Cyclic redundancy check and all algorithms that at one point execute some CPU heavy tasks.
In all these cases you can gain more in performance.
Sometimes you want just integrate a legacy application
So you have the source code of an old C / C++ application and want to expose something of its functionalities through new Node.js application
Even if npm is a very large repo where you can find almost everything sometimes you don’t find what fits your specific needs and in this case you have to take a choice.
Completely reimplementing the module in JavaScript, but in my opinion it’s an insane idea to reimplement from the ground solutions like ImageMagick | Ghostscript | Ffmpeg and TensorFlow because you will lose all your time on develop a module and not to concentrate on business logic of your application. In these cases the
You have to concentrate on business logic of your application and not on developing a single module
N-API is one of the most important features announced with Node.js 8 which is aimed at reducing the maintenance cost for native add-ons
When I start to develop a new native addon I use the boilerplate depicted on the slide. Here the most important elements are the SRC and LIB folders.
SRC folder contains the C / C++ code and the native dependencies
while
the LIB folder contains the JavaScript code
There are also the usual package.json file and the binging.gyp file that contains all the building configurations for the addon.
At the end our addon will be composed by two parts one written in C++ and another written in JavaScript and usually the JavaScript part will use the
native code to expose some features

In our binding.gyp we need to set the target name that will match the module name. The reported example is almost simple sometimes finding the right settings for binding.gyp is not easy so I suggest to take a look at GYP documentation or at nodey-gyp wiki where there are examples of existing binding.gyp and use them as source of inspiration to solve your problems with these kind of configurations.
What happen here?
The macro NODE_API_MODULE creates code that will register a module named ”echo” and in addition it will ensure that a function init is called when the module is required.
In the init we export our function or object. In the reported example we export echo and you can find the code executed by this function in the method Echo.
As first thing we validate the input data, then transfer the JavaScript input to C++ data structure. C++ code perform the requested computation and before returning transfer the output data to JavaScript context.
This is the most straightforward integration pattern that you can realize to pass data between JavaScript and C / C++ . The main reason for using this approach is simplicity and because you can integrate the C++ without modification. In addition we have a complete decoupling of the JavaScript and C++ code.
In an asynchronous addon function, the calling JavaScript code returns immediately.
The calling code passes a callback function to the addon, and the addon does its work in a separate worker thread.
This avoids locking up the Node.js event loop, as the addon function does not block.
