TypeScript Factory Patterns (No BS TS Series 2 Episode 1)
Рет қаралды 34,773
2 жыл бұрынNo BS TS is back! With the first in an all new series where we cover all the patterns in the original Design Patterns book (and more). This time we are looking at the factory patterns; Abstract Factory, Builder and Factory Method. All of these patterns help you build reusable well architected code.

Jack, your content is such a breath of fresh air, most tutorials are aimed at complete beginners which is fine of course but it's nigh impossible to find good tutorials dealing with more advanced concepts, especially when it comes to web development. Cheers man, keep up the good work!

I appreciate concrete implementations of design patterns in Typescript. And I really appreciate seeing *both* a class-based approach and a functional approach. It broadens my mind about the capabilities of TypeScript. Thanks!

I'm so excited! I've been digging into a lot of the content you make lately and it has been challenging me to start writing code where I could describe the implementation in a meaningful, decisive, way. The quality and maintainability of code I write has been dramatically changed from these videos! Thank you so much!

Also in agreement with the other comments on this video we need more tutorials that are made such that beginners can figure out by themselves but where intermediate level script kiddies and other advanced programmers can have fun learning new stuff without having to learn how to install VSCode or NodeJS for the thousandth time 😅😅😅🎉 Jack is great at doing just that, Awesome 👏🏼

Fantastic content Jack! I reckon this has the potential to be a fantastic reference series for most TS developers, but I believe that it could be even more useful if, before jumping into your actual implementations, you could spend a minute or two explaining (and maybe showing the GoF diagram of) the generic pattern, and then, as you're doing, show your example implementation applied to a practical case. That would probably make it perfect.

Great content! A feedback..The builder example was not that good. Because we sshould not have a file reader that do both json and text. But I understand the idea was to show the builder pattern... A better example could be an OrderBuilder, in which you have functions to add item, add delivery address, ... And then return the builder object on these functions. And then you can fluid create the object like: orderBuilder .addItem("item 1") .addItem("itrm 2") .setDeliveryAddress("address") .build()
@jherr 4 ай бұрын
Why wouldn't you want a reader for JSON and a reader for text?
@bachirseghir9952 8 ай бұрын
Jack , I think you used Template pattern in the directory Scrapper when you transformed it from Builder pattern to Factory pattern , using abstract class and overriding it throught inheritance to include the missing methods isJSONFile , readText and readJSON , isn't it ?

Hello, I'm new to design patterns. Just wondering if design patterns are used in real world codebases?
@ngneerin 2 жыл бұрын
Is it that breaking down classes to functionalities such that it can be reusable in different contexts is builder pattern?
@jherr 2 жыл бұрын
It's that you are loosening the coupling between the code that creates significant output from the code that figures out whether it should be created. In the case of builder the pattern is that you are passing the building code to the function or class that does the computing or parsing work. You can see this pattern in things like parsing libraries. So you have the parser that goes through the data, and then the builder that gets callbacks when the parser finds important thing and builds the right output.

Can these/those design patterns be applied/used in react development- I'm just starting to see the chapter and I hear "functional version" so I bet that YES they can... Let´s see...

Yes. These can absolutely be used with react, angular or vue.

@Boris1990ua 2 жыл бұрын
Great video, but I am a little bit confused 🤔 third example Factory Method looks to me more like Template Method, DirectoryScraper delegates implementation of specific behavior to FileReader, not object creation, why it's a factory?
@jherr 2 жыл бұрын
Because the creation of the objects is delegated to abstract "factory" methods. Let's take a database reading class. If it reads from the list of customers and then creates customer objects for each one, then there is a tight coupling there. If it delegates the chore of creating the customer objects to a method, then those can be overridden to create different types of customer objects.
@jherr 2 жыл бұрын
Also, the second and third look a lot like the Strategy pattern. :) Lots of these patterns are closely related.
