Learn Express JS With TypeScript

[@JoJoAcrylicArtwork]

finally a tutorial that doesn't leave you hanging on getting the fuller pic for proper type safety and production level usage. Thanks Tom

[@Skylla54]

I did a 40 hours node js course. These tutorial are just amazing to keep all the concepts and techniques fresh for my next Hackathon. 🤤 And perfect 4 dinnertime :)) 🍖

[@basiccoder2166]

Watch entire video without getting bored or distracted. Beautifully explained

[@MrKeepItTrill]

Came with the intention of skimming this just to see what I need to do to get Express working with TS (turns out not much). Left with one of the best and clearest introductions / refreshers on Express in general that I've ever seen.

[@TomDoesTech]

So glad you liked it :)

[@mizouhamza3244]

I recommend to any new comer to Nodejs with Express. This video is what you need to start and get on your feet, personally I definitely enjoyed it.

[@gosnooky]

NestJS is the goat. Not to confuse with NextJS, the React framework. Some people hate on it because it's TS first and feels a lot like Java/Spring or Angular, but those are both good things in my book because on the emphasis on type-safety and modularity.

[@TomDoesTech]

Yeah, not a fan of NestJS

[@angrysmilex]

28:25 - Request & response generics - YOY!! I finally find this useful and simple solution

[@stijnschuurman9347]

Thanks Tom! I was confused with the `app.use(express.json())` because for some reason it did not function as it should for certain versions. Explained the middleware part really good. Thanks a lot :)

github.com/chiragmehta900/node-typescript-boilerplate-postgres Hey guys, try out this node js typescript boilerplate Please stare at this repository if you like this.

[@Creamworks]

Fantastic video! I'd also love to see a deep dive tutorial on Express + Mongoose with TS (file structure, strict typing etc.).

[@jereramirez7433]

Tom, this is so helpful! Im coming from Java-Spring stack and this is helping me so much to understand what I need to do to work as I used to. THANK YOU!

[@josephjoey3904]

Great work Tom. I have gotten the hang of TS with React but not much on the back end side

[@vilijanac]

It is itself an fake back end side. Client needs at the front end needs to present. Receives only string of text. Most web browsers will reject as an web page.

[@josephjoey3904]

@@vilijanac wtf u talking about?

[@GeorgiosAmsterdam]

Looks like I finally found the video that I need, and for the first time I see an instructor using YARN..... never a break.

[@7MaticCode]

This is the best tutorial for express with typescript. Thank you for this tutorial I learned a lot

[@nextdev3637]

Wow, I was searching for it since 1 hour.

[@arberi99]

Thank you for this amazing video!

Thanks a lot for sharing this great knowledge for free. I never thought I would learn many new things from you.

[@martinlupa8692]

Great video! Thank you!

[@2gbeh]

Let's go 👍

[@adventurer2395]

You’re a good teacher, and this complements your other API video that had a faster pace. Since you’re using TS, it would be awesome to see an object-oriented API.

[@TomDoesTech]

Thank you :) Yeah I will think about an OOP approach, I do prefer more functional programming though.

[@jessejulian9069]

@@TomDoesTech Whats the difference between the two if i may ask? Is it simply receiving and returning JSON?

[@TomDoesTech]

@@jessejulian9069 There's a lot different, It will just confuse you if I try explain it in a comment. There should be lots of videos on YT explaining it

[@true_visual]

I am close to complete my Angular course at the moment. I will soon need to learn Express to come closer to MEAN and I am so excited. Can someone learn Express in 40 minutes though? It seems short unless it's really that quick to learn Express! Thank you very much for this!

[@pheonixking1234]

Very good tutorial!

Great tutorial. Could you advise me, which of your tutorial should I take next, if i interested in backend stuff? Many thanks =)

You could try building the auth API kzbin.info/www/bejne/p6rPeJShnpV9nrs

[@tadeuszjiwu255]

Thank You Tom, great tutorial!

[@k12i]

Thank you Tom for the amazing explanations! I have learnt heaps just from this tutorial :)

[@TomDoesTech]

Great to hear!

[@eyalsolomon1682]

Nice one ! would be better if you had more focus on typescript nice example about Request generics

[@mossaabkanzit9403]

That was really instructional! Maybe in a future video you can cover clean / hexagonal architecture with express and typescript. Thanks for the video and looking forward to more videos.

[@TomDoesTech]

Thanks for the suggestion. I will look into hexagonal architecture and see if it's something I'd make a video out of

[@taosade]

what's the extension for such a cool terminal in vscode?

[@TCErnesto]

11:36 is it needed to type the parameters? TypeScript is pretty good at inferring types. In this case, thanks to the signature of `get`, VSC and we know the types of `req` and `res`

[@k12i]

Hey Tom, what did you use for formatting the code with auto save? Is it prettier?

[@TomDoesTech]

Yeah prettier

[@marianofarace308]

Hi Tom, I'm getting an error on every empty bracket here "req: Request", Don't use `{}` as a type. `{}` actually means "any non-nullish value". How do you deal with that?

[@devloperadda1350]

Thanks

[@rathan235]

well explained!

[@jessejulian9069]

Hey Tom, what script would we use to run the server in production?? I'm referring to the scripts we add within the package.json file in order to run our server. I've watched a few of your videos on Express with TypeScript but I've only seen you set a script for Development

[@TomDoesTech]

What script?

[@yoman9446]

Thanks a lot! Can you do a tutorial on using NextJS with custom express backend with typescript?

[@mybuddy11]

could you please a lecture on micro service with express -typescript?

[@HologramJay]

Thanks for the tutorial, Tom. It was really helpful. I just had a quick question. When typing the Request object, how would we access ResBody? I'm trying to set its type to a string, but I can't seem to figure out how to log it out like I can with req.params, req.body, and req.query.

[@savithadatchu1534]

Hey Tom, What is the use of express interfaces, when even without them the inbuilt functions of req and res are accessible directly.

[@TomDoesTech]

If you pass req and res to a controller for example, in the controller the interfaces are not accessible, so explicit types are helpful

[@indigosay]

You should teach us to extend Request witn additional properties, bro

[@MassGueye-sr4kj]

what was that technic names with middleware

[@valentinussofa4135]

Thanks for this tutorial. I want to ask, Why you don't use nodemon package?

[@TomDoesTech]

don't need it

[@talhakhadim111]

which tool are you using for auto complete in cli?

[@TomDoesTech]

I think it's zsh-autocomplete

[@coderboysobuj]

How to i deploy express typescript project on cpanel?

[@filipedonatti8872]

could explain what is .locals at 28:50 ?Maybe explain a little further about its usability if you don't mind

[@TomDoesTech]

The res.locals object has properties that are local variables within the response, and will be available in templates rendered with res.render

[@editingtuto1.011]

I Want to learn session management with typescript.

[@howuseehim]

How do you build for production? 😢

[@Euquila]

Personally, I use Typescript very minimally. Like, I would never type Request, Response, and NextFunction... that would annoy me as all hell. I might type out the shape of an object or props or something though

[@TomDoesTech]

That's the beauty of TypeScript, it's more opt-in. I usually don't add types for everything, especially if TS knows the type implicitly. However, I add more types in these videos because I want to stress how to find the types that can be used by going into the module and seeing what's exported.

[@Randomuser21265]

Where is the github link?

[@TomDoesTech]

I haven't added it to GitHub because there was no real working code. I can make a repo with all the examples if that would help

[@IkraamDev]

My boss told me Golang is a better tool than NodeJS. It would be interesting if you learnt Go and made a video like this in Go.

[@TomDoesTech]

For what specifically is Go better than Node.js? yeah, I've wanted to learn Go for ages but have only dabbled in it a little bit.

[@kalush81]

There is almost no typescript involved in this video.

[@TomDoesTech]

I don't think stuffing types in where they don't improve the DX is an appropriate use of TS, therefore there is enough TS in this video. If you disagree, that's fine but welcome to tech where nobody agrees on anything.

[@kirarevcrow]

You barely talked about the error handling.

[@TomDoesTech]

I talked about it enough in terms of Express, since it's just normal Node error handling.

[@tejasjani2544]

Js realised it's mistake and want be a java

[@TomDoesTech]

lol what?

[@mjerez6029]

Is 2023 last thing you should do is express, there are waay better alternatives. Express is just awful

[@TomDoesTech]

What if you are interviewing for your dream job and they have a large Express app and expect you to know how to use it? Probably pretty import to learn it.

[@TomDoesTech]

Otherwise I'd agree, I always start new projects with Fastify
