I'm trying to make a website where a user can look through an image gallery of books, each accompanied by the book's name and other properties, such as reading level, number of pages, etc.
I'd be using my own images of the books and entering the data for them myself, but I'm not sure how to store these book objects. I obviously don't want to manually make a <div> for each and enter all the data, but rather use JS to access the list of all the books and their data and output them.
I'm not sure what would be the appropriate method of storing these books. Would I make a SQL database, use localStorage, or something else entirely?
I am sure you do not want memory and performance to be a concern when you design something.
Refer this to know more about localstorage limitations.
I would suggest you go with a database and store it there, will be a scalable option as well. I am assuming you have a crud operation also involved in your website.

I was asked to rework our canteen's website to be more user-friendly to operate for the chef and other staff, who are unfamiliar with coding and content management systems. More specifically, we have a menu page where the meals for the next 3 weeks are displayed, and I was asked to make it easier to update said page.
I figured that the simplest approach would be to create a spreadsheet in Google Sheets or Excel and to pull the data - so the names of meals and some dates - into the HTML page from there, so that whenever the staff needs to update the information, they can just edit the spreadsheet instead of bothering with the backend of the website.
My first approach was to try and connect the HTML to a Google Sheet using Google Apps Script, but this proved difficult since I don't actually know any JavaScript and expected the whole ordeal to be simpler.
I tried following some tutorials I found online, but they a) were mostly for extracting entire tables, not just singular pieces of data and b) they didn't work. I thought about using an actual database program in the hopes that would help, but I don't have access to Microsoft Access at the moment.

I would like to publish a website that hosts menus for different restaurant branches.
What would be good way to do publish this?
Bearing in mind occasional price changes - does this mean taking the website down and re-deploying or is there a way I can dynamically update item prices?
Hosting providers/CMS tools appreciated
I have written the website using basic html/css/js so far.. I have only used django to host a website on the local loopback address. I am determined to learn more.
The first question would be can you access the price data online? (Other websites?)
If you are able, to get the data online then you could create a database and small program which fetches the required data for the website. You can then give that a refreshing rate of 5 min or what ever you like.
Then give your website to access the database and load the prices/data from the database into your website.
If you do not have the data online you can still use a database for storing the prices and other data. If you store the data in database you can load it from the database into your website.
To update the data you can either insert the values directly into the database or you can write an webinterface. (Do not forget to restrict the access to the webinterface)
For the communication I would recommend to use CRUD methods ( Create Read Update Delete) https://en.wikipedia.org/wiki/Create,_read,_update_and_delete

I'm building a project that requires me to get Pictures, Price & URL of an amazon product.
Each user has his own product, and other users can see other users' products, and i have everything saved in a database, so I was thinking of scraping data but that would be too much on the server to scrape on each request. so I'm trying to find an API where I can get Product URL, Product Image & Product Price from just the keyword of the product.
would love some help.
Keepa API and ProxyCrawl API have this funtionality, but both of these are paid solutions. Also, you will always get multiple products per keyword. If you want a 1:1 match then it's not possible using just a keyword- you would need an identifier like an ASIN.

I have to display more than 50k rows with data. Using pure angularjs main problem will be speed and data caching. Can you advise a library or direction that is solution to my problem?
Do not "ever" display so many items at once to a user.
If you find your self in a need to display so much information, something is wrong with the way you have thought about how your users will interact with the application.
A couple of things to look into should be :
Paging the data ( filters & pages, much like any e-shop for example )
Use the correct HTTP response headers to allow browsers to cache requests, on the other hand you can even try to cache queries on the server, instead of hitting the database every with every request
Now caching data is a trade off between "data time updates & performance across the platform". Some times the data must be "live" so you can not really add any caching logic, but most of the times you can get away with "x minutes old data", 2,3,5 minutes, depending on what you want to achieve, that will greatly improve performance for the platform, both for the users experience, as well as for the system's stability

Is there a means of looking up a bank name & branch through Javascript?
Perhaps an external service or an complete data-set that can be hosted internally and accessed through JSON?
For anyone still looking, the APCA themselves publish a continually updated list of BSB numbers which you can download in CSV format here.
You can obtain BSBs from Australian Payment Network and load them into your database.
This is pretty good, but sometimes the list can be a little out of date. Also, the banks may close a branch and remove it from this master list of BSBs. However, transactions to that BSB will continue to work because they do a redirect to the new BSB.
