Viable options for running NodeJS on Android (Aug 2017)

Asked 2018-Sep-11 at 08:16

There are a bunch of old SO threads dealing with running NodeJS on Android. Most of these are no longer viable (JXCore) and/or provide confusing, outdated, incomplete, or erroneous information.

Therefore I have investigated what seems to be currently (as of August 2017) viable approaches and found three likely candidates.

To decide between them I would like to know:

the primary differences between these approaches
specific pro's and con's on each approach
likely hurdles, challenges and shortcomings
do you know of other viable alternatives?

Viable approaches are:

Running V8 javascript engine which includes NodeJS (J2V8)
Use NodeJS directly, embedded as native library (node-on-android)
Combining React Native with NodeJS app-as-a-service (react-native-node)

Besides that I have found a number of related interesting resources:

NPM install NodeJS directly using Termux without rooting (not for end-users)
LiquidCore - native mobile micro-app devenv (not investigated, interesting concepts)
dna2oslab - has a working NodeJS build script for node executables
Building NodeJS for Android - blog with useful compilation tips and example project

I received an answer from @dna2github, the creator of NodeBase (thanks a lot!) that I'll include here (with permission):

Hi,

Thx for your question. I will do a brief answer in my view.

1. Running V8 javascript engine on android which includes NodeJS

pros:

integrated with Java world; can get full control of code.

cons:

a little hard to integrate with 3rd packages (need time to learn how).
need to learn about NodeJS and V8 things and also J2V8 docs (it consume long time).

2. Compile NodeJS as a native library (using node-on-android)

pros:

focus on js dev and no need to consider android side.
less learning time; similar to Cordova phonegap ....

cons:

js app => apk is a black box.

3. Running NodeJS on Android using Termux

pros:

flexible

cons:

no gui

4. Other interesting approaches

Not familar with LiquidCore; build micro service especially from url, I think, is to resolve no direct available storage on iOS. react-native-node the Android part is based on NodeBase method and use the prebuilt binary.

For NodeBase:

pros:

similar to 3; difference is that it has its own gui to start/stop app.
it can be a template for everything; for example, if would like to run django, you just need to replace node to python; rails, ruby...

cons:

native process access problem; the process cannot inherit access from Android app.
happy toy happy open source not like a commercial app; need more design if want to distribute to customers

At first, I run node in terminal; I find only dev can easily to use it to start js app. My friends and families also wanna some tools for example make water mark on picture in batch. NodeBase is created for them to easy to start/stop app. Then they just need to open browser to use it. My another idea to create NodeBase is that we can build sharable applications that can be shared in the same Wi-Fi. When host starts an app, it can be visited by near people. Then they can work and play together. For example, we play werewolf and when there is no judge, we will start the werewolf app to have a judge for the first round. We can also share files between devices via download/upload.

For me, I can build what I want flexibly for example, I would like to make my Android as a machine learning runner; it can help me run machine learning programs at anytime (with node and python, thus in my another repo: dna2oslab is focus on building binaries) to make use of phone running time.

For you, if wanna port your app in a short time, I recommend 2; if you have time and other resources, 1 is better. 3 if you just make a toy/demo. 4 other is always possible and just do your imagination to create works.

Best wishes, Seven

QUESTION

Multithreaded solution (instead of multiprocesses) for reporting server

Asked 2017-Aug-11 at 06:28

NodeJS is still not multi-threading after those many years since first release. JXCore is multi-threading but dead. I need multi-threaded JS server for my project, any solution?

NodeJS cluster mode can't solve my problem as my server has reporting API, 4 heavy reporting requests from client-side can hang the whole 4 CPUs of my server.

It should better slow down all requests rather than having capability to serve 4 heavy requests only.

...

ANSWER

Answered 2017-Aug-11 at 06:28

NodeJS does support multi-threading via the child_process API.

You can use child_process.fork to spawn new threads running a specific js module and opens an IPC communications channel to pass data back and forth between them.

QUESTION

How to use "require" in JXCore C++ application

Asked 2017-Jul-14 at 19:34

I'm attempting to use JXCore in order to call up some node.js code inside my c++ program. I'm able to run my C++ program with the attached code if I comment out the line: "var path = require('fs'); \n" So I've basically narrowed down my issue to when I use the "require" command. The code works if I run it from jx directly. I'm also using Visual Studio if that makes a difference. How do you tell jx where the additional modules like 'fs' are?

Found the answer on here: https://github.com/jxcore/jxcore/blob/master/test/native-interface/test-require/test-posix.cpp#L9

Basically, 'require' needs to be defined in a global.

QUESTION

JXcore vs Electron

Asked 2017-Apr-14 at 14:08

question

I am wondering what the main differences are between Electron and JXcore.

background

I was thinking about how I could make a NodeJS server into an app and I came across both of these. They seem to do the same thing, except that JXcore supports mobile and Electron doesn't.

side question

If Electron doesn't support mobile then how was the slack mobile app created?

Thanks in advance!

...

ANSWER

Answered 2017-Apr-14 at 14:08

From the JXCore site(http://jxcore.com/tech/):

JXcore is a fork on the open source Node.js project

It uses LLVM to compile javascript as opposed to V8 which NodeJS does.

In terms of what are the main differences- Electron is a framework for building native, cross platform desktop applications, where it appears JXCore is a javascript engine forked from NodeJS.

Electron is built with NodeJS, and Chromium. So to make it fair, the comparison would be better stated "How does Electron work with NodeJS vs JXcore". Since I don't have any experience with JXCore, I can't answer that question. I would venture to say the only way to know that is to fork electron and replace Node with JXCore.

Based on your background, I would assume you are thinking about making one application that works cross platform across mobile and desktop environments. To that, I would say it is possible, but you are going to have 2 different projects. There are things in Electron that you wouldn't want included in your mobile app, since they are working with completely different operating systems. You are right that electron does not support mobile (it wasn't built for that).

As far as your side question goes, there are any number of technologies that slack could have used to create their mobile app. They could have used Java , Swift, Objective-C, .NET, Ruby, or Javascript.

There are cross platform tools such as RubyMotion, NativeScript, React Native, and Xamarin that could also be used to create native mobile apps, that all compile down into the native language the mobile OS understands.

A final approach could be the use of tools such as Cordova/Phonegap which create mobile apps via a "web view". Essentially, this is like creating an app that launches a web browser to interact with your phone.

If you are looking for an example on how to build once and use everywhere, I would look at the github repo found here https://github.com/NathanWalker/angular-seed-advanced. This shows a common codebase that can be used in Electron, Web, and Mobile.

QUESTION

run nodejs application on system which does not have node

Asked 2017-Mar-14 at 07:08

I have developed a nodejs application for a client, but obviously asking a client to install nodejs and npms in their system does not look good.

NPM's does not work if we simply copy paste them, we require to do npm install 'npm name', which is also an issue.

Assuming that client does not have internet access in their system, I want a single exe or some file which on click can work without any need to install any npms or nodejs. Is there something which can make it happen? I am sure there must be, which I am missing. I will be grateful if someone can help me in this

Thanks in advance

UPDATE

I am not getting option to answer my question so updating the question itself

How to install NodeJS project locally without internet connection?

this was really helpful.. that is how I can zip my modules and install it at some other machine .. and

this can be useful to run project as a single file

Answered 2017-Mar-11 at 07:26

SSH into their system and install it. Not hard at all. Depending on their operating system would determine the steps needed to be taken. That's the only proper way to do it. I do it for clients on the daily.

QUESTION

node js - How do I create build for commercial usage?

Asked 2017-Feb-28 at 05:17

I am working on node js application and it is now ready to use. I want to make exe of this application so that it can be used for commercial usage.

Up to now I have used enclose module using which I have compiled the code of application but I have found some issues in that (app got crash on idle condition). App is running good without enclose or compiled code.

I have searched on google and found some alternate modules like JXcore, Node webkit and Electron etc. but JX core giving error same as in SO question.

In node web-kit, it's functionality is not looking suitable as we need its executable and some dll's along with our code, which makes our package bulky.

I have also tried jxcore. The main problem with the exe's and with modules that we use is their ability to work with native modules, in my case the Kinect.node module. This module cannot be compiled. We need a workaround to package only this along with our .exe file. Enclose provides this workaround in its inbuilt functionality.

Also looking a response from EncloseJS, which is actually run by just one person who gives further instructions upon purchase. A purchase is needed for commercial usage.

In case of Electron, It is supporting only Electron-based application source code. So If I choose this then I have to modify my application code.

So can any one suggest me what can I do to make exe file from node js code there?

Thank you!

I had the same issue before, the node js application close when running in background. now i am using process manager2 (pm2), it is working fine and if the application is crash due to any other reason it is automatically started again.
