QUESTION
Problem
I have deployed a Node.js/Express.js/Mongoose API to Heroku, however when I hit the endpoints I get a 503 status code and the Heroku prompt telling me there is an application error.
Attempts at a solution
I read on a different Stackoverflow post that you needed to add the MONGODB_URI as a config var in the settings of your Heroku app, so I added the connection string and changed the MongoDB connection to:
...ANSWER
Answered 2021-Jan-21 at 17:17You should add IP address in your mongodb account. Just go to mongodb clusters then click on the Network Access and add this ip 0.0.0.0/0
QUESTION
I thought this would be easy, but still can't find an easy solution. I simply want to set the page title (and document.title) to a specified string that I choose. I know I can access useLocation and get the current route, but that doesn't work with logical human naming. For example, my route might be /new but I want the title of the page to be 'Add New Thing'. Notice that I've added a new prop for the page title that seems like a logical place to add it (then use a useEffect to pull it), but can't figure out how to access this prop.
If this isn't the correct way, how would you do this? Should I instead setup a dictionary/lookup for the current url(useLocation) and assign a human page title?
Main goal: If someone DIRECTLY hits a URL '/new' how would you set the title?
My current structure is from a base create react app.
In my index.js
...ANSWER
Answered 2021-Jan-13 at 15:51use document.title = "Add New Thing";
on your CreateQuiz component. im not sure if its the best way. But it works for me
QUESTION
I'm making a React PWA which works fine on localhost to cache all the listed files but when I deploy the project on Netlify or any other platform it won't cache the files and is not working offline. The cache storage shows empty list which in case of localhost shows all the files I'm caching. The service worker file is being registered in both cases.
The link to my github repo is here: https://github.com/noumanmalik960/quiz-app-pwa
Here is service worker file code:
...ANSWER
Answered 2020-Nov-15 at 16:56The reason your cache list is empty as few of the files which you mentioned in your cache list does not exist. Check below screenshot. If any of the files which you have mentioned in your cached List (in your service worker) is missing or browser not able to find that then it will create the cache entry but will not be able to cache any files.
Fix your above mentioned files url and then your service worker will work as expected.
QUESTION
In my Angular quiz app, I had the same logic: option.selected && option.correct
and option.selected && !option.correct
in both of my question component (MultipleAnswerComponent and SingleAnswerComponent) templates, so I moved out the logic and added two variables to the QuizService to share/reduce the duplicate code:
ANSWER
Answered 2020-Oct-07 at 12:55isCorrectOption
and isIncorrectOption
both are (not empty) strings and therefor evaluates as truthy.
Change your code to this and you should be fine:
QUESTION
I have added a dropdown with both numerical and percentage scores in my scoreboard score component, but the score doesn't seem to increase when a question is answered correctly, it just shows 0/4 or 0%. I'm including my code below and please could you see my Stackblitz and help to fix this issue. Thank you.

Answered 2020-Oct-20 at 17:07Your stackblitz is different from what u pasted here. But I think the case is u need to call this.score$ = of(this.score);
only when this.correctAnswersCount$ is emitting new value.

QUESTION
I separated my quiz question form into two components, one for single-answer and one for multiple-answer, and now the answer(s) are not getting passed from the question components to the QuizComponent and also not getting pushed to the answers array.
This seems to be affecting the display of explanation text and scoring is not working.
Please could you see my Stackblitz: https://stackblitz.com/edit/angular-10-quiz-app and help to fix this issue. Thank you.

event in question.component.html from codelab-question-single-answer and codelab-question-multiple-answer. You just need capture answer output.
QUESTION
I am working on a quiz ResultsComponent using Angular 9, but having difficulty getting the results to display correctly in the mat-accordion with the data. I have a userAnswers array, correctAnswers array and a quizData.ts external file containing the quizData array object, and I am showing a summary of the results to the user, specifically "Your Answer(s)", "Correct Answer(s)", "Explanation" and "Elapsed Time" for each question in the quiz.
In testing the app, the user answer option number(s) sometimes do not seem to correspond with the correct option text; the same goes for the correct answers. In the multiple choice questions, options should be displayed as "1 and 2", not "1, 2" in the correct answers and explanation. I've passed the correct options string (with "1 and 2") to the ResultsComponent, but it should probably be an array of strings of correct options in case of several M/C questions. Also in testing, sometimes when the user answer and correct answer are different, the correct checkmark is shown, even when the user answer is not correct.
I am sharing a snippet of the code below, but you can view the entire quiz here: http://stackblitz.com/edit/angular-9-quiz-app. I would appreciate your help with these issues. Thank you.
EDIT: I need to use the Results model so that I can have:

QUESTION
I'm working on a quiz-selection component. I would like it to route to specific quiz based on quiz.id in QUIZ_DATA array in external quiz.ts file, for example TS-Quiz or DI-Quiz. When I click on the TypeScript Quiz (TS-Quiz), I am getting the DI-Quiz intro; it should be the TS-Quiz intro information. Not sure how to use the quiz.id type that is passed to the IntroductionComponent in [routerLink].
And I'm getting this error when loading the first question in the quiz: TypeError: Cannot read property '0' of undefined
I would like it so that the select page is first (done), followed by intro (based on quiz.id), then questions (based on quiz.id), then results.
Please see my running app on Stackblitz: https://stackblitz.com/edit/angular-10-quiz-app
My [routerLink] is below:
...ANSWER
Answered 2020-Jul-14 at 21:25Looking at the quiz.component.ts
, in getQuestion (line 85)
method, the getQuestions
method of the Quiz Service returns an array, not a object. So, the property questions will be undefined.
Looks like the quiz id is missing, you need to get the quiz id to get the questions of that quiz, something like this:
