Node.js Translation to Spanish - (1282 words) (Part-66)

in #utopian-io5 years ago (edited)


Project Details

Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser.

Node.js came into existence when the original developers of JavaScript extended it from something you could only run in the browser to something you could run on your machine as a standalone application.

In simple words, it's an open source execution environment for developing web applications, which is event-based, it uses the V8 engine to provide an execution environment that compiles and executes JavaScript at a higher speed. It is possible to run Node.js without any restriction on Windows, Linux and Mac OS X.

It should be noted that it is NOT a server language, this means that it executes code, so it could be understood as an interpreter.

Contribution Specifications

Node.js is currently being translated into 33 languages. I'm contributing to translate it into the Spanish language.

So far, we have managed to translate 65% of the project!

Translation Overview

I started the translation of the folder


N-API (pronounced N as in the letter, followed by API) is an API for building native Addons. It is independent from the underlying JavaScript runtime (ex V8) and is maintained as part of Node.js itself.

Previously, I briefly explained what an API is. If you want to see more information about it, you can visit this post.

The N-API is an API that ensures ABI stability across Node.js versions and different compiler levels. And an ABI (application binary interface) it's the interface between two program modules, it determines details such as how to call functions, in which binary format information should be passed from one program component to the next, or to the operating system in the case of a system call.

In this part of the module, how to work with JavaScript properties is explained.

N-API exposes a set of APIs to create all types of JavaScript values. Fundamentally, these APIs are used to do one of the following:

  • Create a new JavaScript object
  • Convert from a primitive C type to an N-API value
  • Convert from N-API value to a primitive C type
  • Get global instances including undefined and null

As an example of the work done, I will use part of this section called Functions to get global instances:


Functions to get global instances


  • [in] env: The environment that the API is invoked under.
  • [out] result: napi_value representing JavaScript Global Object.

This API returns the global Object.


  • [in] env: The environment that the API is invoked under.
  • [out] result: napi_value representing JavaScript Null Object.

This API returns the null Object.


  • [in] env: The environment that the API is invoked under.
  • [out] result: napi_value representing JavaScript Undefined value.

This API returns the Undefined object.


  • [in] env: The environment that the API is invoked under.
  • [in] value: The value of the boolean to retrieve.
  • [out] result: napi_value representing JavaScript Boolean singleton to retrieve.

This API is used to return the JavaScript singleton object that is used to represent the given boolean value


Funciones para obtener instancias globales


  • [in] env: El entorno en el que se invoca la API.
  • [out] result: napi_value que representa el Objeto Global de JavaScript.

Esta API devuelve el Objeto global.


  • [in] env: El entorno en el que se invoca la API.
  • [out] result: napi_value que representa el Objeto NULL de JavaScript.

Esta API devuelve el Objeto NULL.


  • [in] env: El entorno en el que se invoca la API.
  • [out] result: napi_value que representa al valor Indefinido de JavaScript.

Esta API devuelve el objeto Indefinido de JavaScript.


  • [in] env: El entorno en el que se invoca la API.
  • [in] value: El valor del booleano a recuperar.
  • [out] result: napi_value que representa el singleton Booleano de JavaScript a recuperar.

Esta API es utilizada para devolver el objeto singleton de JavaScript que es utilizado para representar al valor booleano dado

I was struck by the word singleton is, the singleton is a well-known and widely used design pattern. Restricts the creation of instances of a class so that it only creates an instance of the class that implements it.

Its intention is to ensure that a class has only one instance and provide a global access point to it. It is not responsible for the creation of objects in itself, but focuses on the restriction in the creation of an object.


Via Refactoring.Guru

The most common situations of application of this pattern are those in which this class controls access to a single physical resource or when certain types of data must be available to all users. other objects in the application.

The singleton pattern provides a single global instance thanks to:

  • The class itself is responsible for creating the single instance.
  • It allows global access to this instance through a class method.
  • Declares the class constructor private so that it is not directly installable.
  • Being internally self-referenced, in languages such as Java, the garbage collector does not act.
