What is the best way to learn express.js?
Figure out some concept you want to achieve. Example.: basic website with login, image upload, users follow each other and see something like a feed. Now you have one, then first of all u need some pages, then some pages with the need of auth. Along your journey, these little steps are necessary to know what you need to google, or ask for some advise here. Specify your questions to only one step like how can you save an image into blabla folder. This is the way. What you said about udemy and youtube stuff is very true they just show you the whole image without telling the logic (maybe they do not know either, just learned this only stuff and trying to sell themselves to you, more youtube ad more bullshit), that is why you need to do yourself with small achievments.

r/node on Reddit: What is the best way to learn express.js?
May 4, 2022 -
Hello everyone,
Currently trying to learn express.js, I have quite a bit of knowledge in vanilla javascript but im trying to expand my knowledge to nodejs and some backend frameworks. Im having trouble finding good resources to learn express.
Here are my concerns with what I've seen:
- express js docs are kind of bland and hard to follow along
- udemy videos are filled with 15+ hours of content with mostly fluff
-pdf books online are mostly outdated
-youtube videos are thirty minutes and keep reiterating the same stuff ex setting up, routes, middleware .... they don't cover a lot of in-depth stuff just basics.
If anyone knows of any good learning resources that don't contain any of the annoyances above ^ please feel free to comment.

October 8, 2025 - It has been called the de facto standard server framework for Node.js. The original author, TJ Holowaychuk, described it as a Sinatra-inspired server, meaning that it is relatively minimal with many features available as plugins. Express is the back-end component of popular development stacks like the MEAN, MERN or MEVN stack, together with the MongoDB database software and a JavaScript front-end framework or library.

I agree that the Express documentation reads a bit more like a book than an API doc. In the case of express.static, this is a re-expored middleware from Connect (connect.static), which Express is built on. From the middleware section of the docs:
Typically with connect middleware you would require(‘connect’) like so:
var connect = require('connect'); app.use(connect.logger()); app.use(connect.bodyParser());This is somewhat annoying, so express re-exports these middleware properties, however they are identical:
app.use(express.logger()); app.use(express.bodyParser());
You can see what middleware Connect exposes on their web site. In particular, check out the documentation for the static middleware.

express is the class and static is a member of that class. What express.static means is "use the static method of the express class", what the static method does is initialize a static file server to be served by your node.js server.

r/node on Reddit: Best Way to Learn Node.js & Express? Struggling with Documentation
March 19, 2025 -
I’ve been trying to learn Node.js and Express, but I find that the official documentation sometimes lacks clear explanations or requires me to search for additional information on other websites. I’m not very comfortable with learning directly from documentation, so I’m looking for a more structured approach.
For those who have mastered Node.js and Express, how did you learn them? If you were to start over today, how would you go about it? Also, could you recommend some comprehensive courses that cover all the essential topics, including backend best practices, authentication (JWT), APIs, security, databases, and deployment?
I’d appreciate recommendations that go beyond the basics and dive into advanced concepts as well.
Thanks in advance!

r/node on Reddit: Best way to document Express API
April 5, 2022 -
So, I am aware of swagger and jsdoc. Im wondering what the best way would be to document an Express API ? Swagger seems to be geared towards allowing interactivity through a web interface and something that is public facing. JSdoc seems to be a little closer to what I may be looking for since it seems to just generate a website locally.
Basically, I am looking for something that would be private and allow for private documentation for a back end API that's only used for interfacing with the front end.
Also, if i use lets say JSdoc, would I define the documentation in the routes file? Controller file? Model file?
Whats the industry standard way of doing this?
Im looking for suggestions on how to approach this. Any ideas? Thanks!

The right way imho to do this is write OpenAPI files, and use those files to validate your implementation. What you're describing is the opposite (use code and infer the contract). This is a bit of a debate and plenty of people don't agree with this, but I find that thoughtful, well-designed APIs typically follow this pattern. This is especially important if you're building an API consumed by third parties. If you yourself are the one and only consumer, it might matter less. Then after you have your OpenAPI files, you can generate HTML documentation, Typescript types and SDK's for all your clients.

I've used Slate to document APIs which similarly will produce a local website. You can host that privately or there's built in support to push to github pages if you're hosting it in a github repo. The documentation itself is all written in markdown and managed separate from your API code.
