I'm getting some tweets from the twitter API with nodejs and saving some of the data with mysql. Gradually as I require more and more data from each tweet, it's become obvious I should just save the whole tweet each time. I'm looking for the cleanest way to save a whole tweet straight from a JSON object to a new row in my db.
I was surprised there aren't more node modules or anything pre-written for creating the database table ready for tweets and mapping a tweet's JSON schema directly to it - can anyone help? At the moment I'm using the 'mysql' module for queries and thought about combining it with 'json-sql' for building the query, but it seems like this must be such a common thing that there should be an even simpler way.
Is anyone aware of another process? Thanks!
I eventually moved over to using MongoDB, it works really well with NodeJS and I'm really enjoying it.

I am working on school project where we need to create website and use Redis to search database, in my case it will be movie database. I got JSON file with names and ratings of 100 movies. I would like to upload this dataset into Redis instead on entering the entire dataset manually. JSON file is saved on my desktop and I am using Ubuntu 20.04.
Is there a way to do it?
I have never used Redis so my question might be very silly. I've been looking all over the internet and cannot find exactly what needs to be done. I might be googling incorrect question maybe that's why I cannot find the answer.
Any help would be appreciated.
Write an appropriate program to do the job. There's no one-size-fits-all process because how your data is structured in redis is up to you; once you decide on that, it should be easy to write a program to parse the JSON and insert the data.
I know this kind of question is ask in many different ways, and I know that's annoying for answering so much same question, but as I google it, search in Stackoverflow I can't really find a nice answer, the answer I'm asking is based on views like easy for answering API request (which is in JSON format) and in the view of I'm designing Node.js APP
So here is my case
I'm building my own Node.js application somehow like a CMS or blogging platform so imagine I need a place to store all my posts data where should I store in a MySQL database or External JSON file it's quite confusing I personally prefer JSON since it's nice looking (?) but it's quite hard to use fs.writefile and fs.readfilesync to update data in the external JSON, but I don't know how to make an API that will give the post data by MySQL database since the API is in the JSON format
If I have any misunderstood please tell me
if you want to store data in json then go form nosql database like mongodb. Postgresql latest versions also supports JSON data types.
Maybe what you need is ORM module, for example sequelize
It works with MySQL/Postgres, and offers you APIs like MongoDB.
I am designing a system with 30,000 objects or so and can't decide between the two: either have a JSON file pre computed for each one and get data by pointing to URL of the file (I think Twitter does something similar) or have a PHP/Perl/whatever else script that will produce JSON object on the fly when requested, from let's say database, and send it back. Is one more suited for than another? I guess if it takes a long time to generate the JSON data it is better to have already done JSON files. What if generating is as quick as accessing a database? Although I suppose one has a dedicated table in the database specifically for that. Data doesn't change very often so updating is not a constant thing. In that respect the data is static for all intense and purposes.
Anyways, any thought would be much appreciated!

You might want to try MongoDB which retrieves the objects as JSON and is highly scalable and easy to setup.
I'm a real beginner when it comes time for this, so I apologize in advance.
The long and short of what I am looking for is a fairly simple concept - I want to pull JSON data off a server, parse it, and load it into excel, access, or some other type of tables. Basically, I want to be able to store the data so I can filter, sort, and query it.
To make matters a little more complicated, the server will only return truncated results with each JSON, so it will be necessary to make multiple requests to the server.
Are there tools out there or code available which will help me do what I am looking for? I am completely lost, and I have no idea where to start.
(please be gentle)
I'm glad seeing this question b/c I'm doing very similar things! And based on what I'd gone through, it has lot to do with how those tables are designed or even linked together at first, and then the mapping between these tables and different JSON objects at different depth or position in the original JSON file. After the mapping rules are made clear, the code can be done by merely hard-coding the mapping(I mean like: if you got JSON object after a certain parent of it, then you save the data into certain table(s)) if you're using some high level JSON paring library.
OK as i have to dash home from the office now:
Assuming that you are going to use Excel to Parse the data you are going to need:
1.Some Json Parser JSON Parser for VBA
2.Some code to download the JSON
3.A loop of VBA code that loops through each file and parses it into a sheet.
Is this ok for a starter? If you are struggling let me know and I will try and knock something up a little better over the weekend.
I'm trying to migrate from a custom designed blog software system to a WordPress.com site. I can access my MySQL database of posts and comments without too much difficulty, thanks in part to this post: How do I connect to a MySQL database from Clojure?.
I think my next step is to generate the pseudo-xml file known as a "WordPress eXtended RSS file", and that's where I'm having difficulty. I can navigate my way through the recordsets returned from my database connection (as of now, I'm doing two SQL searches, one for posts, and another for comments, giving me two recordsets), but I don't know what sort of data structure I should put those results into in order to eventually export them into the xml file.
I've been using a lot of file spit/slurps while working my way through this, but I have a feeling that's neither the most efficient way to do it, nor the most "lispy" way.
I think what I need is help defining a clojure-based data structure that I can append both new posts and new comments to, iteratively, for eventual export into the xml file format I need it to finally get to.
Look at clojure.xml/emit and clojure.xml/emit-element; they expect data that look as described in (doc clojure.xml/parse) and walk this data to output XML.
