POST contents of a listbox

Hi! I have a dual listbox thing where the left and right is populated from a database. There's some buttons and a bit of JS that allows items to move left and right between the two. Basically copied this and added my own database logic: https://codepen.io/afrost/pen/EyQOxx My data/schema is pretty simple - id# and a name....

Express JS Router: persisting data

I have some "router" modules being exported into my app.js from a people.js & auth.js file. Both of these router modules (people.js & auth.js) are require()'ing an array of objects called people, which is being module.export'd out of data.js. Each object inside this people array represents a person', each holding an 'id' and a 'name' property....

Understanding a tutorial: Using axios.get()

I'm following a tutorial that uses Express JS to create a server and integrates it with some 'static' resources (html, css, js).. showing how app.get(), app.post() work with a form etc (pic 1 & 2) There are 2 'versions' of the form that the tutorial goes over. One of them, (the index.html), links the form to the server, in app.js, with a method = POST. (pic 3) There, we're using a require() to get a people array out of a local file (data.js), and in our app.post using that info to test against the user's form input. (pic 1)...

What's the best headless CMS for creating a social media platform?

Hi guys, was wondering about my options for a headless CMS to create user profiles and add comments to things. I'd be using React. I know there is no best, but was wondering what my options were and what works for you guys. This would be for freelancing so I need something that's easy to set up but secure and flexible Honestly though, I've never worked with a headless CMS so I'm not sure if that's even the best tool to use. I just want something that's easy to create user profiles and add comments in a production environment pretty much. I'd appreciate any insight you guys have...

NodeJS app.js requiring a JSON file?

I know that if I had some JSON data in a .js file, that I could, at the end of that .js file, do a module.exports() of that JSON module's name, and then require it in my app.js, and use a res.json() on it. (pics 1-3) But what if instead of having that JSON data in a js file, it was housed in its own .json file? I couldn't do a module.exports() from inside a .json file. ...

"absolute path" <-- starts from "root" directory

How far back do we mean when we says an 'absolute' path goes to the 'root' directory? In the context of an ExpressJS app.. Would the "root" be the project folder correct? And if so, how does it know to stop there and consider that the 'root'. Is it looking for some identifying file or something? Like package.json?

Express JS install giving many venerabilities, incl 'critical'

I'm following a tutorial which is about to get into how to use Express JS for setting up a server, and I went to install Express and got back all kinds of venerabilities, including critical. I don't have anything else installed except for 'nodemon' for auto-restarting the server upon save. Does any one know why I'm getting all of these venerabilities?/If/How to address them?...

Vernacular: "API" vs "module"

PHP - What's going on here?

Hi.. Quite new to LAMPy stuff - I'm trying to pick apart a bit of code here. Can someone explain what's going on? I get what it's doing, I just can't put a name to the functionality to explore it further if that makes sense. `php > unset ($error); php > echo (empty($error)) ? 'The string is empty' : 'The string has something in'; The string is empty...

Conceptual understanding of form submitting to a server-side script.

If I need a form to, upon submit, take in the user inputs, analyze them against a .json file for matches, and then "get"/fetch the correct objects from the .json.. and have those objects populate an HTML template.. Would my server-side language (ex; PHP) be what would analyze the user input and also import the .json objects in order to search through it? And then also be where the templated HTML would be created?...
