I am working on an electron project to keep inventory of a warehouse but I want to store the data on the client-side (on the client's desktop/laptop) and not on a cloud database. How do I do this? Is using an xlsx file a good idea to store the data. As it will come with an added bonus as the user can read the data outside the app if they want to in an excel sheet.
P. S: even if xslx is a way I would like to know other possible ways so I can choose which is more comfortable for me. Thank you.
Edit: sorry I forgot to mention that I might also have to store images in the data.
You have plenty of option. You can store json file and read it when application boot up. As this is node js related thing I would suggest you to use electron store
And xlsx is a good choice but that may be overkill if the thing you are storing is too simple. On windows you can store some settings in registry too. But I prefer the config version.
I have also used sqlite3 database for some app. In Android I believe many app uses sqlite approach to store local database.

I have a python script that fetches data twice a day from a server of mine. The script returns around 40 JSON files containing various data. The files aren't particularly big and the combined size of all the files is around 250KB.
Alongside my script I am developing a dashboard in React that renders the data from each file into a table, allowing me a visual representation of the data.
I have been looking at what would be the best way to store these files, something that allows me to upload and fetch them twice a day.
Someone mentioned to me about using MongoDB to store the files, but after some research I feel like Mongo is better at storing the contents of the file rather than the file itself. I tried to develop a solution but I couldn't figure out how it could be done when each object is stored as a document with no clear way (to me) which document came from which file.
Other options I have considered are:
Storing the files on the server that is hosting my React project and rendering them locally as I am doing now during development
Storing the files using a provider such as AWS/Firebase
Storing them in a different database (I see SQL now support the storing of JSON files)
Are there any other solutions that you think would work best for this scenario? If so, why?
Hello,
Check about use of FTP server.
We have clients that send us data every 10 min via FTP that is inside XML files, then I have NodeJS back-end which read these files.
You can use it for your scenario with JSON files.
I want to make an app as my final project for my teacher. I will have images of homework assignments and the date of homework assigned in text format in the server. And I want to make an app where it will access it and put it in an activity.
So I need to know what kind of server do I need, if I could just use google drive somehow or not?
Save it as JSON, you save the images on your database and call it in your JSON.
But for what you intend to do I think FireBase will work just file because it is free for small projects like this.
In an application, I am using Fabric.js, which lets users write text, draw SVG's, insert images etc.
I want to know, what is the best way to store this data.
Requirements are:
Ability to query the data(text), which tells me that i should store it in DB (MySQL as of now)
I have images, and I am targeting IPad as well, so the images are important, as to how they are stored.
SVG's and HTML/CSS to be saved as well.
I also want to do versioning of the content, as Quora does it, so that a user can see the changes from the past version to the current version. This also includes the versioning of images and SVG's.
I am wondering how Google Docs does it, because they also store our documents, drawings etc.
What is the best way of doing this?
i dont known if it helps but, Opera browser offer an option to save the webpages to an unique file { mht extension }, this stores all the files { css, images, scripts, etc } in base64 encoded text for a later use { when the document is opened }... maybe this can be a way to store data :P
I manage a webapp where users generate reports, and found it more efficient to store images and binary files in the filesystem, and link to them from the database. Elements that are in xml or text are kept in the database for easier searching - in your case this would include css/html and svg (which is xml). Use the database for managing revisions.
Might also check out this thread on storing images in a database.
It looks like Frabic.js is using the node.js javascript webserver on the backend - haven't used this before, but you might investigate which databases are easiest to use with node.js:
node.js database
nodejs and database communication - how?
nodejs where to start?
If you want to query the text efficiently, then perhaps putting all bits of information into the DB separately is the most efficient. Maybe you with to play with OOXML or ODF, that may serve as container for all information you require, and then XML-storage (e.g. eXist) to store it and query (e.g. the text). As these standards are XML-based, you can transform them into HTML (e.g. here or here) but writing an online editor for this is something that monster like Google can do.
You can take a look at NoSQL databases like MongoDB or
CouchDB

I am interested in creating a video databse. My goal is to have a folder where my videos will be kept and each time I copy/delete a video the website that presents them should be updated to. the problem is I have no idea how to approach it.
Should I..
Use Sql and store a reference to each video location?
Have a script that checks all the time if new changes happen in that folder?
A package like joomla?
I am using ubuntu btw. I already have a simple html5 page, and I am presenting the videos using html5 video.
It depends on the size and the performance you want.
1.Way : use php to scan the folder and generate links on the fly
2.way : Use a database to store the file names and retrieve the names from the database and generate urls
pros and cons.
simple to implement , no changes in upload or download script. no database required.
You need have a database , little coding required for upload and also while genrating a page
You should make a db (format does not matter) and storing in it only file names of videos: the videos would be stored on hard drive.
Any operation on the web site will pass first on db for insert/update/delete videos records and then (maybe in a transaction context) on the file system.
This would be the standard approach to your question.
I want to create a a application in actionscipt 3.0 that allows the user to listen to music and read descriptions of the music. For this to happen i suppose there should be a database where the textbits and music is located and then flash fetch the info when the correct buttons are pushed. The database will contain up to 100 tracks and textbits.
The application will function on a stand that won't have a connection to the internet.
What is the easiest way to do this in actionscript 3.0?
If any of you are familiar with UML and thinks this might help in understanding the problem, then here is use-case and flow-chart:

Thanks in advance.
The easiest way to do what you're asking is probably to store the files in a directory on the machine the application is going to be running on, and then design an XML structure for storing your data. The XML is easily loaded in to Flash at runtime and is easily edittable.
Your other option would be running a database server on the machine, creating web services that run locally and push/pull the data from the database, and then call those services from your Flash application.
The first option is most definitely the easiest and should be able to provide exactly what you need. The second would be more geared towards a distributed Flash application where you needed a central data repository for the clients.
If you're building an AIR application, you can use the integrated SQLITE database. But, i agree with Justin, the easiest way is to use a XML file.
You can probably consider using "Local Shared Objects" which is a kind of cookie, with bigger capacity (100Kb by default, but you can change it). Compared to other solutions already proposed, it has then advantage of not requiring any web server.
