Node.js Translation to Spanish - (1521 words) (Part-69)

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 69% of the project!

Translation Overview

For this contribution, I have finished translating 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 final part of the module, simple asynchronous operations are explained.

Additional modules often need to take advantage of the libuv asynchronous helpers as part of their implementation. This allows them to schedule the job to run asynchronously so that their methods can return before the job is completed. This is important to allow them to avoid blocking the general execution of the Node.js application.

It also explains the use of custom asynchronous operations, considering that the simple asynchronous work APIs may not be appropriate for each scenario, and these APIs are necessary to ensure that the execution time correctly tracks an asynchronous operation.


Via Lemoncode

Recall that when an operation is asynchronous, the completion of the operation is notified to the main program and the processing of the response will be made at some future time.

I will use as an example the simple asynchronous operation function napi_cancel_async_work:



This API cancels queued work if it has not yet been started. If it has already started executing, it cannot be cancelled and napi_generic_failure will be returned. If successful, the complete callback will be invoked with a status value of napi_cancelled. The work should not be deleted before the complete callback invocation, even if it has been successfully cancelled.

This API can be called even if there is a pending JavaScript exception.



Esta API cancela el trabajo en cola, si aún no ha sido iniciado. Si ya comenzó a ejecutarse, no puede ser cancelado y napi_generic_failure será devuelto. Si es exitoso, la callback complete será invocada con un valor de estado de napi_cancelled. El trabajo no debe ser eliminado antes de la invocación de la callback complete, incluso si fue cancelado de manera exitosa.

Se puede llamar a esta API incluso si hay una excepción de JavaScript pendiente.

I will also use the custom asynchronous operation function napi_cancel_async_work:



This method allows a JavaScript function object to be called from a native add-on. This API is similar to napi_call_function. However, it is used to call from native code back into JavaScript after returning from an async operation (when there is no other script on the stack).



Este método permite a un objeto de función de JavaScript ser llamado desde un complemento nativo. Esta API es similar a napi_call_function. Sin embargo, es utilizada para llamar desde el código nativo de nuevo a JavaScript luego de regresar de una operación asíncrona (cuando no hay otro script en la pila).
