My experience with Termux and NodeJS on Android

Image
By
The first thing I did was install Termux from the play store. Termux provides terminal emulation and a linux environment. Read that I should install updates

$ apt update && apt upgrade

Next I installed nodejs

$ apt install nodejs

Next I needed an editor to create my code files. I decided for an external editor and shared external storage. By default Termux uses app private storage. Shared external storage needs to be setup as follows

$ termux-setup-storage

This creates a $HOME/shared folder in Termux that links to Internal storage in Android file manager. I created a folder called WEB/nodeapp for my project in there. Next I needed a code editor app. For that I chose Quick Edit.

Next was to create my starter node project

$ npm init

I got the following warning message, "npm WARN npm npm does not support Node.js v13.0.0". I fixed this by upgrading npm.

$ npm install -g npm

Next was to create my server.js code and test it.

var http = require('http');

http.createServer(function (req, res) {
  res.write('Hello World!');
  res.end();
}).listen(8080);

$ npm install
$ npm start

I got an error, "npm ERR! nodeapp@1.0.0 start: `node server.js` npm ERR! Exit status 1". The error message also listed a log file to check for details but I ran the code directly to see the error.

$ node server.js

I got the following error, "Error: listen EADDRINUSE: address already in use :::8080". I change the port to 3000 and that fixed it.

NodeJS on Android


This is some exciting stuff to me. Didn't think that so much coding could be done on Android before I switched to a mobile workflow for my blogging. There is an app that can be used to specifically run nodejs code called Dory - node.js that I will look at in future blog post. I like termux because I can setup other coding languages like C++ and Ruby. Share your experiences with us in the comments below.

Hobby project - Store and view exchange rates

By
The next step in my project was to test out being able store and display the rates in a database. I decided to use nodejs and supabase for this. Everything worked beautifully. Only hickup was the following error due to my package.json not being correct. SyntaxError: Cannot use import statement outside a module Added this to package.json   "type": "module" This works beautifully. Right now I am just testing fragments of what could be part of a bigger system to see what is possible and what works and how easy to code on a mobile. There is no fully functioning integrated end to end system just yet. This is also what I tested. A serverless append-only database using GitHub + Actions + Pages. That’s basically a lightweight backend system. This was the ChatGPT prompt I used. Guide me through each step. This is what I want. A manually run github actions that adds to docs/data.json with the current date and time. docs/index.html displays all the entries in data.json. Make s...

What is important

By
Every now and again, I get reminded of the why. Why I have handed my life over to God. It is 3:08 p.m. and I have decided to write. Honestly, I feel like I could end this blog post right here. What more is there to say? God above all else. God is our compass on this journey called life. Everything else can become a distraction. Maybe not everything, but certainly many things. You get the point. What is important? What do we prioritise? What do we make time for? The answers look different for everyone. Our lives are different. We are tested differently. We are all products of our circumstances, and those circumstances vary from person to person. Yet God is the common thread across humanity and throughout time. God always was and always will be. One day, we will answer to God. We will give account to God. We cannot live without food, water, and oxygen, but all of those things come from God. So how can we live without God? How timely. I just received a notification from the Quranly app: S...

Hobby coding project - Queries for play whe data

By
I have an interest in open data and being able to query that data and gain beautiful insights. One data set that would be interesting is the play whe results data. Our open data is lacking in Trinidad and I will try to contact NLCB to see if they can provide and maintain the data online. But in the meanwhile I will use randomised data to create the website and do my testing. First thing I did was install sqlite on termux pkg update && pkg upgrade pkg install sqlite sqlite3 --version Create my database in my project folder sqlite3 results.db Useful commands .exit .quit Exit from multiline prompt ; SQL to create my table (create_tbl_results.sql) CREATE TABLE DrawResults (     DrawNo INTEGER PRIMARY KEY,                           DrawDate DATE,     ResultNo INTEGER CHECK (ResultNo BETWEEN 1 AND 36),     DrawTime INTEGER CHECK (DrawTime BETWEEN 1 AND 4) ); SQL to create the random dat...
