I’ve seen many people complaining in twitter about Vercel pricing and how cheap it is to run your own VPS instead of using Vercel. Migrating is quite easy, I’m not a devops engineer and it took me just a few hours to figure it out and automate my whole deployment process, I believe it’s worth investing the time as you will save thousands of dollars potentially. In this tutorial I’ll show you how to setup Github Actions to automatically deploy to your VPS on every new push to main. The Continue reading

Generative AI requires a lot of resources and powerful equipment, you need to buy Nvidia cards to being able to successfully run stable diffusion or any other model. If you are like me you might look for affordable solutions such as AWS. In this tutorial I’m going to show you how to install Flux to generate awesome images in Ubuntu. Setting up the instance First thing you need to do is to login into Amazon AWS console, in the top search input, type EC2 and select the first option in the Continue reading

One of my favorite things to do is learning new things all the time, a couple of years ago I decided to lear how to play the violin! It's being a long journey that I've enjoyed so far. One of the problems beginners have when learning to play the violin, is the fact that you never know if you are playing the right note, the violin doesn't have any kind of mark that you can use as a reference to position your fingers and play the right note. It'd be really nice if you can get instant feedback on Continue reading

I started using Notion a couple of years ago (in 2021) to manage my YouTube content. I really liked the product and the simple way it allows me to organize my ideas, scripts, personal journal, etc. So, I decided to use it for my personal blog as well. One of the challenges was to display Notion information on my website. Fortunately, Notion has a Rest API that provides access to all your content. In this tutorial, I'll show you all the necessary steps in case you want to do the same. I worked Continue reading

Today I needed to write a test for a component that uses a hook from our common library, but at the same time I needed to use other components in the test. Initially I mocked the whole module and got all previous tests to fail, the issue was that I mocked everything and no other component was working as expected. Here's the code I wanted to test. import { Text, File, useToast } from '@my-library/ui'; import axios from 'axios'; export default function Uploader({ userId ) { const showToast = Continue reading

Testing redirections in jest using react router is not a straight forward process, specially when using hooks. In this tutorial I'm going to show you how to test a redirect, in addition we are going to test the state in the history. The code we will be testing is a button, when clicked we will redirect the user to a new page using react router, but we are also going to set some data into the history state. import React from 'react'; import { useNavigate, useLocation } from 'react-router-dom'; Continue reading

I've been maintaining a React Native app for several years now, I don't update it very often because it's really just a side project I have. A few years ago I released an Android version, at the time I generated the keystore file and put it in a secure location, but to be honest I don't remember where I stored. If you are in a similar situation, don't panic! Is quite simple to recover it, actually... you need to create a new one and submit a request to get it updated on the Google Play store.

One of the most popular feature requests of the Music App is to support memberships using Stripe. A few days ago I decided to work on this new feature, however, I found a few challenges along the way. First of all, if we want to use Stripe we need to run our application over HTTPS, otherwise the JavaScript SDK doesn't run properly. In production that's quite easy to accomplish, in fact, the demo version, as well as the community I run using this software, are both running over HTTPS. But when Continue reading

I've been maintaining a React Native app for several years now, I'm really happy with my stack as I can quickly add new features and iterate for Android an iOS. However, a few days ago I migrated to Sentry as my third-party service to keep track of crashes and errors in the app. Everything went well on iOS after installation, however, on Android, I started getting errors when trying to build the app. D8: Cannot fit requested classes in a single dex file (# fields: 67142 > Continue reading
