Five Essential Design Patterns in Typescript

I'm going to "do it live!" as I bring you five essential Design Patterns, from the GoF book, in Typescript, live, as you get to ask questions along the way! Super exciting, I can't wait to see how it turns out!

One thing I can guarantee is that you will come away from this with a decent idea of what these patterns are and code that you can reuse in your applications.

Hope you folks enjoy this!

After 3 years, this video continues on helping people understand these concepts and I'm an example of that. Thank you so much! Instantly subscribed after the video.

Thank you so much for your perspective. This type of growth would never have ocurred to me without someone of your expertise mentioning it. Lots of

[TheGabrielMoon]

You are awesome, dude!

Your content have been help me a lot even with the simple questions I had

[CodingNuggets]

Jack, you are awesome. Really happy to say that I follow you. Big fan! Also, thanks for your amazing content. Much love and see you soon!

[adventurer]

Thank you! We need more content like this, building node APIs with TS and design pattern/SOLID principles. A suggestion: As someone already pointed out, your implementation of the factory pattern is not full. It's more of a facade. You'd need arguments (enums for instance) for the factory to allow for implementations of different databases types on the fly.

[mmmmmmm]

So disappointed i missed this! Great stuff Jack.

For 1 min 40 sec I was thinking my headset having issue .
Nice video

[DavidSmith-efeh]

Great tutorial. Next one could be how to organise medium to large projects in a maintainable way. All I know is Uncle Bob's domain driven design, but this seems a bit overkill for me...

[abba_m_]

I think this is where I finally learn generics 😅 great content 👏👏

[John-Dennehy]

Really useful to see these patterns that I hear my backend/Java colleagues talking about. Though, I'm curious if they are still considered best practice in TS / modern JavaScript. I'm struggling to think of scenarios where these patterns work better than more simple, easier to read/reason.

Really nice and useful Tutorial.. thaanks

[DanielJustavino]

Every time I come to this channel theres something better in store, keep it up Jack!

[rembautimes]

Thanks for this lecture. I tried out the code but the visitor pattern had to declare item:any as a workaround I was getting an error : " Argument of type '(item: T) => void' is not assignable to parameter of type '(value: unknown, index: number, array: unknown[]) => void'.". if I used item: T as per the interface. But its a small issue, the code was a great exercise.

I searched the entire web for such tutorials where design patterns are implemented in use cases.

[Lemmy]

I think i would rather implement all this by using:
- Map for inMemoryDb
- EventTarget + CustomEvent for the pub/sub logic
- Proxy to proxy get and set methods of Map with pub sub events

In the old days we also set in the config file the kind of DB the Factory is returned when invoked.
