It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

I've converted existing VueJS SPA into Android apps with CapacitorJS. The guides was easy to follow and the application is working good. Just need to change the icons and enable camera for file upload.

Learned a bit about Twilio and its Conversation API. Will be using it in the next freelance project.

I've been playing around with repl.it since I found out you can use it to deploy web servers. This means that is basically like a "full stack codepen".

I learned how to setup a tiny web server with 6 lines of code*.

(*) not counting the dependencies.

// index.js

const router = require('find-my-way')();
const static = require('serve-handler');

const assets = (req, res) => static(req, res, {'public': './public'});

router.on('GET', '/hello', () => 'Hello!');
router.on('GET', '/*', assets);

module.exports = (req, res) => router.lookup(req, res);

And 1 command.

node_modules/.bin/micro -l tcp://0.0.0.0:3000 index.js

Ok, technically you need to install things first. That'll be 2 commands.

npm install micro@9.3.4 serve-handler@6.1.3 find-my-way@4.0.0

There you have it a (useless) web server with a fully functional router and capable of handling static assets. Here's a more exciting example in repl.it: micro-quote-machine.

How to create buffers and splits in Vim. I made some notes on my findings in my TIL repository here.

This is for posts relating to vim, as well as vim plugins, integrations and workflows!
