Flavio - New free tutorials from Flavio!

Hi Reader

Today I have a few free tutorials for you.

But first, I have something you might be interested in. 

A few people asked me to do a new cohort of the JavaScript Masterclass. I had plans for it in the fall (the first cohort happened in Nov 2021), but seeing this interest I'm considering anticipating this second cohort.

It will be a 2 weeks long intensive course to focus on the fundamentals of the JavaScript language with a dedicated community and mentoring from me. It will be limited to the first 20 people, as that's a size I can personally do mentoring for. Pricing will be the same as the first cohort, $397. If you're interested reply to this email.

Let's now go on to this week's free tutorials.

First, I got back to writing daily blog posts (a short write-up of why I temporarily stopped, and why I resumed!)

How to test Netlify Functions locally

How to create a IAM user in AWS

How to upload an image to S3 using Node.js

What's the use of the hashtag # (number sign) in the links?

`npm run dev` is a long-running program

Most of those tutorial ideas come from challenges I had while working on projects or from questions I get asked in my courses, and I once I answer I take the time to make a blog post if that's something I think it's useful for many people.

I also started doing more troubleshooting posts because while working on a long list of projects, I ran into all sorts of issues, and I started accumulating solutions to those problems, including:

How to fix "cannot use import statement outside a module"

How to fix "__dirname is not defined in ES module scope"

How to fix tsconfig.json "No inputs were found in config file" error

How to add days to a date in JavaScript

Blank page after router.push() in Next.js?

I like to write them down so the next time I run into those issues, I won't have to spend much time looking for a solution. And hopefully, they're helpful to other people as well.

That's it for this week.
