Even most of the paid courses are not offering what you're teaching here. Thank you so much for giving us such an in depth course

[@ansonthedev]

This course surely blew up, I am thankful that you all found this video. If you have any questions please ask them down below, I do my best to respond to all comments when I check them, which is very frequent. Let me know by replying what other videos you would like to see (Doesn't have to just be ExpressJS)! :)

it s what I wanted to start 2024. thanks a lot

[@axlYT]

What about TypeScript integration? Im coming from frontend and java backend so idk if there is any development server tool (like vite for frontend) or cli command to setup express with TS and also ESlint for regular backend apps. Or is it just a standard to setup it manuallly ? Would be cool to see an actuall pro setup

i forgot to mention above thanks for the video it was very helpfull

Excellent instruction. I did a full stack software engineering bootcamp this summer and we covered this material but I felt I still had a lot of knowledge gaps. The instruction here moves at a good pace, goes into enough detail and is well explained. I am 1 hour in now, hoping to finish the rest within a week. Will update after finishing the course. High expectations at this point. Great Job Anson.

[@ansonthedev]

Glad you found this video helpful. :)

[@TrxsTer]

2 hours in and I have really learned many useful thing. I came to this video to revise on some of the few things I had forgotten but was amazed to find such a good way to teach. Can't wait to continue and complete the rest of the video.

[@ansonthedev]

A lot of people have asked this question, and I want to address it, I should've mentioned this in the beginning of the video: "Do I need to learn Node.js first before learning Express.js?" Remember that Node.js isn't anything special, it's just a runtime environment that you can simply use to execute JavaScript code on the server-side, or your local computer, instead of the browser. If you already know JavaScript from using it on the client-side, then you honestly will not have any trouble with understanding JavaScript on the server-side. There will be differences, because the browser has its own APIs, and Node.js has its own APIs (remember, browsers have their own JS engine that can interpret and execute code). All you are doing is just writing JS code and having it run on the server side, aka your local machine, and you use Node.js to do that. While Node.js may have a lot of built-in APIs and functionalities, such as the file system API (fs) or the http API, trust me, you will know when you will need to use those APIs when the time comes as you're developing your project. Don't worry about all of those native APIs Node.js provides, every single runtime environment or language will have their own that you don't need to memorize or know until you need to use them. As long as you know how to write some JS code, and execute it on your local machine through the command line, then you should have no problem learning Express.js, or any JS framework. Thus, Express.js is one of the best frameworks to learn as a complete newbie because of its unopinionated nature.

[@sauravghosh7487]

Earlier i had zero knowledge of MERN & APIs but After just learning the basics of nodejs, i continued to this video with a lot patience and taking one-week time . Finally in two weeks i am now able to built built REST CRUD apis. A very very big thank youuuu.🙏🤝👦.

[@three-zeros]

Hello, Anson! The course is excellent! You explain the most difficult topics very well and quickly! But the question is: will there ever be an Express.js in combination with MySQL, SQLite, PosgreSQL? It would be very nice to see, because there are very few such courses on KZbin

[@Newtrojan]

Yes please. One full backend project with postgres/prisma

1:39:18 if anyone is getting type error undefined {id}, its because your mockUsers are located beneath the middleware, so it is an empty array until you get the declartion order right.

[@dzanful]

I haven't watched the whole video yet, but I'm coding along and the content so far is really instructive. Regarding the part where the `id` value is validated using the `Number.parseInt()` method, it's worth mentioning that it will convert any value where the first non-whitespace character is a digit, meaning `2foo` will be converted to `2` while `foo2` will return `NaN`. Another important thing to be aware of is that if you pass a hex number `0xa`, it is assumed to have a radix value of `16` (hexadecimal), so the number `10` will be returned. This could be avoided by passing a radix value of `10` as the second argument, then `0` would be returned. Perhaps using a simple regex instead would be a better solution, e.g. if the expression `/^\d+$/.test(id)` evaluates to true, you can safely use `Number.parseInt(id)`, then there is also no need to pass the correct radix value of `10`.

[@mandarkulkarni8443]

Thanks for making the video, it did help a lot to kick start API development using JS technologies. A quick question, How can you modularise the development of API endpoints with express.js ? In the video for example, all of the endpoints managing the USER resource are defined in a single file named 'index.mjs' (in practice might be better to rename is as 'users.mjs'). Let's say, I have 10 or 20 such REST resources to be managed in my application. (Say, USERS, ACCOUNTS, ORDERS, PRODUCTS, TRANSACTIONS, etc.) Each of these REST resources will need to support all HTTP verbs (GET, POST, PUT, DELETE, etc.) How do you go about maintaining the application code for all of these endpoints and how can you actually package them together in a deployable artifact (docker image, may be) and run it on one of the cloud environments ? Also, managing the development of middlewares shared across all of these API endpoints will be quite interesting to think about. Disclaimer : I have primarily developed REST API endpoints using Java-Spring Boot all along the years and exploring the JS world only recently.

[@ansonthedev]

I'm not sure how far you gotten into the video, but the part where I introduced routers at 2:20:00 is where I have different routes for different resources. You can see that I have users.mjs and products.mjs both in the routes folder. Both of which are its own individual router that get registered with the main Express app instance in the main index.mjs file. I of course chose not to do this so early in the video to not overwhelm the viewer. But generally, yes you do not want to include everything in one single file as it makes it difficult to maintain. Since you've used Spring Boot, I suggest once you get used to the Javascript realm of things, specifically developing apps with Express.js, I would highly recommend you learn Nest JS. It's architecture is very very similar to Spring Boot and has great ecosystem, has things like Dependency Injection, IoC, etc. In regards to Docker, you'd just use it to create an image of your app and can either deploy it to a host provider that manages Docker containers for you, or deploy it yourself to AWS or Digital Ocean's Droplet.

Hi Anson, Can you create a tutorial on how to the a search function on express js?

[@mamoudgad4210]

very simple very easy you are awesome man thank you for this tutorial

[@Tony.Nguyen137]

@2:11:00 why is it recommend to use the function matchedData? What advantage do I have? if the data is valid I can also access it in the body without using matchedData

[@ansonthedev]

matchedData collects all of the data from the request body, and sanitizes it. express-validator.github.io/docs/guides/getting-started#accessing-validated-data

[@itsformac]

if we use same spread operator in put same way as you did in patch, output would be same, then why do we need patch? 1:05:15 - put 1:15:10 - patch

[@ansonthedev]

So I am doing two different things in PUT and PATCH. For PUT, I am using the spreader operator inside an object to take all fields and values and assign it to mockUsers[findUserIndex], which is the original object at its specific index in the mockUsers array. This is me replacing the entire user in the Array with what I sent via PUT. For Patch, I am using the spreader operator on the original user object, so that way ALL existing fields and values are first placed in the new object, then whatever the request body is, I am using the spreader operator on that which will override any previous field-value pairs set. Hopefully this makes sense.
