After last episode with Templ maintainers I was really pumped to try Templ and see if it would work for me. Without spoiling too much I believe it would have been easier to start from scratch with Templ vs. trying to migrate an existing project.

This led me to try and see if I could add static analysis of my templates in my library tpl. I don't really have a PoC yet, but kind of getting close to it. If everything continue I should be able to capture errors in using of wrong field in template, like typos in field name that are caught at runtime at this moment.

I started a monolith-style web application couple of weeks ago and force to admit that Go is more and more fun to use where I was considering more like Django or Rails before.

For me there was still the templates aspect that needed to be fixed, and I wrote a library for that. The other major place where I was not enjoying myself was the database code, found it way to repetitive for application that had a lot of SQL tables.

We're in a very good place at the moment and the benefits of having a compiled language to build heavy backend web application is great.

I've restarted active development on my open source Go backend server API StaticBackend. For a long time I wanted to make its CLI size smaller, and I decided to use Go's plugin package to extract a functionality that used a dependency that was accounting for more than 50% of its 170 MB. Go plugin were the solution I decided to use for this and I explain the problem and the solution in this episode.

I've been building SaaS since 2008 and built two with Go. Big spoiler, the technology you choose has a little impact in the early stage of a software business. There's some danger to over-engineer and use complex construct while you still does not even know if what you're building is desirable. Heck, you don't even know what you're building at first.

I'm giving some example of common traps and pitfails technical founder tend to fail into when jumping into a startup venture for first times. And yes, times is plural, because it takes multiple attempt before learning lessons.

My upcoming SaaS product at first wasn't suppose to be rolled out as a product, but was for my own usage. Turns out as I was using it and selling my online courses that it appears to me as being fairly usefull and could compete against existing course selling platform.

The hic is that it wasn't built as a SaaS in mind, so I have to deploy one application per customer. It's completely multi-tenant. To help with automating the deployment of a new tenant, I wrote and orchestrator with agents to facilitate the deployment of a new application. I thought this part could be interesting to hear about as it's written in Go.

In this episode I talk with John Arundel about cryptography in Go. John wrote a great book on the subject called Explore Go: Cryptography.

In 2021 Twilio sent a termination email on their Fax services. I was consulting as the CTO in a credit bureau that was in the start of an acquisition process with Equifax Canada. There was just no time to "waste" on changing provider and rewriting this part of the system to satisfy the new provider API.

Would have been grand if the provider would have offered a shim that replicated Twilio's API and map that to their own API. Imagine how many companies needed to rewrite this part at the same time. Offering this as the provider that receives X thousands new customers would have been a superb engineering experience.

So maybe we can apply this concept internally as well. When a team needs to introduce breaking changes, a good solution might be for them to provide a shim over the old API so no other teams need to do anything.

This is obviously a tad dangerous and might introduce some technical debt. But as everything, it depends.

I believe we can do better regarding software engineer interviews and this entire process (also including onboarding). I think companies that will be mediocre at those two aspects will have a hard time with younger programmers, which I fully support.

Iterators are going to be useful to process large amount of data without having to load an entire slice or maps in memory but instead create iterators that can be used from a for item := range myIterators().

Things were very different when I started as a junior developer. This is a story of an out of the ordinary day where worked from ~9h am to 11am (the next day), the two of us that were in charge of everything at a small financial company.

This one has nothing to do with Go, but I thought it was worth telling as a story.

As we're building more and more of distributed systems I believe that one trait / culture successful team will require is discipline. Personal opinion, we tend to complicate our lives in the last decade compare to what things were before. But without an extra attention to some details, it will be a nightmare to maintain systems in the long run.

As always, if you'd like to support the show the best way is to purchase my course. Sharing it also very much appreciated.

I talk about dependencies management in Go. How to keep your dependencies up-to-date and how to check if there's any updates available. What to do when a package change their major version.

I'm trying to make my open source backend API project StaticBackend as easy as possible to contribute.

Couple of things I've added lately was worth mentionning. GitHub Codespaces is helpful and nicely done. It goes 1-step further than Docker and make contributing to an open source project a simple task, especially for small and quick 1-time contribution.

This couple with GitHub CLI, which I admit, have just starting using it. And linters to make sure the quality of the code is as high as it can be.

I talk about what I'd love to see coming to web development. While WebAssembly can be used as an alternative to JavaScript, I believe we're not looking into the real problems related to building web application.

It has been a rough last 4 months for me and I finally get a chance to restart publishing episodes. 

In this episode I talk a bit about what I've seen so far as process / flow for deploing software in production. Going from the old days when I started as a junior software dev where we were pushing straight into prod to what I discovered at a big organization where putting something in production spread accross multiple days and involves a lot of people.

I'd like to hear how things are working for you, what is your process from bug fix/new feature to production. I'm genuinely curious after the experience I had seeing how thins can be tedious for this process.

This is the last episode of 2022. Those are my thoughts about how I think we should try to help more as user of open source project and librairies.

This episode content was inspired by the Gorilla Web Tool Kit archiving their Go projects.

On that note, I'll be back with more Go content on January, and will try to keep my 1 episode per two weeks plan for 2023.

Thank you!

- @dominicstpierre on Twitter

I recently created an exportable Go package from StaticBackend, an open source backend API which was self-hosted.

I ended up using the internal package way to heavily and this design decision bite me when I decided to create an exportable package. Now all things that needed to be expose that was in the internal package had to be refactored into their own packages.

Usage of -ldflags:

go build -ldflags "-X main.varName=from_build" -o mycli

Inside your code:

var varName string

func main() {
  fmt.Println(varName) // prints "from_build"
}

Here's what I'm using for StaticBackend -v flag:

go build -ldflags \ 
"-X github.com/staticbackendhq/core/config.BuildTime=$(shell date +'%Y-%m-%d.%H:%M:%S') \
-X github.com/staticbackendhq/core/config.CommitHash=$(shell git log --pretty=format:'%h' -n 1) \

I've been maintaining 20 years old systems for a long time now. I've been working with legacy applications in .NET. To me Go has some great advantages built-in by design that should help in 10-15 years from now when the applications that are created today will be on maintenance mode.

What are you thinking about Generics? What about 3rd party libraries that will pop from everywhere once Go 1.18 launched?

Personally, I'll appreciate what the std lib offers and will wait before writing generics code, making sure I really need it.

I'm currently working on a free and open-source self-hosted Firebase alternative - if such things sound interesting, please join the Discord group and contribution are very welcome (it's written in Go of course).
