Libraries for error tracking for nodejs similar to Sentry?

Alex — Tue, 08 Sep 2020 06:49:46 +0000

Hi, I am looking forward some free options libraries that will track the errors of my server like sentry.io does for nodejs. If you have used one and want to share your experience with it, I would be glad to hear you!

Should I save the code submitted by the users before running and testing it?

Alex — Fri, 29 May 2020 11:06:43 +0000

Hi guys, I am working at a project and I want to let the users submit some code for testing(I know about the security riscks). Now I want to know if I should save the code in a database before running and testing it. If so, how can I make my server to check every second if new code was submitted or not(I am using laravel)?And can I open a new process for every code that need to be tested?

How to store the online lessons learned by users?

Alex — Thu, 02 Apr 2020 18:41:43 +0000

Hi guys, I am currently working at a project, an online website where people can learn programming by advancing through lessons, so I need to know what lessons they have completed. Should I create a table named "completed lessons" with the columns: lesson_id and completed_by_user_id ? I don't know if this is a good idea, but don't have others.

How should I save my blog posts in order to appear as a search result in google?

Alex — Thu, 26 Mar 2020 15:04:09 +0000

I want to create a site where I can write some blogs. I don't know how should I save them. If someone search something like "how to do something", I want from google to display my post as a result and my URL to be like "https://myBlog.com/how-to-do-something". Now I am pretty confused if I should use a data base or a static page for every post. How should I do it?Sorry if my question is dumb, but I really need an advice.

How could I make a secure site?

Hi guys, I want to create a site, my first one. I already have some experience with this, but I've never had a public one. I want a basic site, with a login/up system and some basic lessons from some school subjects. I want to know how can I can make it safe to use, keep your data in and make some payments. I basically want an example of this kind of stuff, where can I find a tutorial or some simple examples that will make me develop it in a safe way. Thanks :D!

Ignoring ajax request

Alex — Fri, 10 Jan 2020 13:19:30 +0000

Hi, first of all, I want to apologize if my question isn't right for this forum.
I am currently working on a project which consists of a chatting website similar to google hangouts. I created a form in javascript destinated to write someone's name in and add him as a friend. I did that yesterday with an ajax request for the server-side and it worked just fine, but now it is ignoring my function and I don't know why.

My js code:

let body = document.getElementsByTagName("body")[0];

let mainList = document.createElement("div");
mainList.classList.add("mainList");

let addFriendForm = document.createElement("form");
addFriendForm.id = "FriendForm";

// The main problem is here

$('#FriendForm').submit(function(){
$.ajax({
url: '../letschat/Functions/createUserRelation.php',
type: 'POST'
});
});

// ^^

let addFriendField = document.createElement("input");
addFriendField.classList.add("addFriend");
addFriendField.placeholder = "Add a friend";
addFriendField.type = "text";
addFriendField.name = "addFriend";
addFriendField.autocomplete = "off";
addFriendForm.appendChild(addFriendField);

mainList.appendChild(addFriendForm);

body.appendChild(mainList);
