Behind the scenes this week I have been continuing my work on the next major iteration of the CodeReviewVideos website.
I’ve split the site into two parts:
- A Symfony 3 powered JSON API for the back-end.
- React / Redux / Redux Saga for the front-end
It’s a stack that I really enjoy working with, and is all stuff I’ve covered here on the site before.
Progress has gone fairly well this week. As a developer I always expect to be further ahead than I actually am. Partly this is impatience, and partly because I am still not so good at estimating 🙂
By next week’s newsletter I am hoping to be able to share access to the “beta” (for want of a better word) with existing site subscribers.
Become An Instructor
I really want to make CodeReviewVideos as useful to you as possible.
There are likely dozens of topics you’d like to see covered that either I have not yet had chance to record videos for, or do not have any experience in.
Topics like Angular 2/4, Vue, WordPress, Magento… all the things that we as developers have to work with in our real-world, day-to-day jobs.
If you have ever wanted to start recording screencasts / tutorials then this may well be the perfect opportunity to do so, and earn some extra recurring income in the process.
If you’d like to know more then please send an email to firstname.lastname@example.org.
This week saw three new videos added to the site.
#1. How to add a Flash Message on Successful, or Failed Login
I got asked this question:
how can I “$this->addFlash” for login? Because now its working only with registration. How can I make it work with login? Check if signing in was successful/not successful?
There is a solution built into Symfony’s security bundle (think: Login form configuration) to make this fairly easy to accomplish.
There is just one small problem: lack of documentation / example.
I’m hoping to correct that with this video. Before going too much further, you may be wondering:
What are Flash Messages?
Flash messages in Symfony are simply one time messages – notifications, by another name – that are stored in the session and are removed as soon as they have been shown once.
If still unsure, I have a video called the Beginners Guide to Symfony Flash Messages. It’s free to watch.
Symfony 3.3 comes with some improvements to the way Flash messages work.
We cover how to add a Flash Message using the success_handler and failure_handler services. The tricky part is that these two services must behave a certain way, and this video covers one approach to this problem.
I’m always open to answering questions like this, so if you have any that you feel would be best answered by video then do please send them in.
It’s good for the CV.
It’s also complicated.
In this video we take a look at a Dockerised environment in which the latest version of Symfony 3, an nginx webserver, and a MySQL database can be “spun-up” in next to no time.
The idea here is to take a look at what’s possible, rather than me saying: Hey, this is all you need to know.
I’ve planned out the Docker series and it’s going to be a few shorter series that can be watched independently, or all together.
There are a bunch of topics in Docker that you can initially skip over. Only as and when you have a need for either a more complex setup, or want to satisfy your curiosity do you need to delve any deeper.
This is good, in my opinion, as Docker itself is both broad and deep, and if we covered all the fundamentals upfront then you may be sound asleep by the end of the first few videos.
Because seeing code is fun, here’s the docker-compose.yml file that this video covers:
You can watch the video here, and then hit the Repo over on GitHub.
We will cover everything in this repo piece by piece, building more than just a Symfony stack in the process.
Oh my, this sounds dull.
Yes, I hear you.
There are parts of Development that sound sexy and fun (e.g. Docker, the latest JS framework, real-time mobile apps, etc), and then there are the dry and boring sounding topics that unfortunately, you really need to know.
I realise permissions aren’t much fun.
That’s why I have compressed the essential knowledge down into a 4 minute long video.
If you have ever seen something like this:
➜ ~ ls -la Development/docker/nginx
drwxrwxr-x 4 www-data www-data 4096 Apr 3 19:43 .
drwxrwxr-x 74 chris chris 4096 Aug 17 20:15 ..
drwxrwxr-x 2 www-data www-data 4096 Apr 3 19:37 conf.d
-rwxrwxr-x 1 www-data www-data 137 Apr 18 20:51 Dockerfile
-rwxrwxr-x 1 www-data www-data 13 Apr 3 19:42 .dockerignore
drwxrwxr-x 8 www-data www-data 4096 Aug 19 12:05 .git
And you have wondered just what the heck most of this means then this video will see you right.
To work with Docker it is essential you understand just a small amount of this output. Most every problem I have had with Docker has been related to permissions. Trust me on this, if you want to use Docker then you need to know this stuff.
And the good news is that it’s really not that bad. And it’s useful beyond working with Docker too. Win win!
Until next week, have a great weekend, and happy coding.
