Node.js With Android

In this tutorial, I am telling to you how to use Node.js with Android Device (Include Smartphones). Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine.

How to use Node.js on Android

Android support is still experimental in Node.js, so precompiled binaries are not yet provided by Node.js developers.

However, there are some third-party solutions. For example, Termux community provides terminal emulator and Linux environment for Android, as well as own package manager and extensive collection of many precompiled applications. This command in Termux app will install the last available Node.js version:

pkg install nodejs

For LTS (Long Term Support) Version

pkg install nodejs-lts

Currently, Termux Node.js binaries are linked against system-icu (depending on libicu package).

Similarly You can use C, Python, Go etc programming language in Your Android Device easily.

What is Termux ?

Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required. A minimal base system is installed automatically – additional packages are available using the APT package manager. It combines powerful terminal emulation with an extensive Linux package collection.
