frontender | Setup a server frontend with HTTPS | Continuous Deployment library

I recently picked up Neo4j as it seemed the best type of database to store data I'm currently scraping off a number of online discussion forums. The primary structure of the graph is Community -> Forum -> Thread -> Post -> Author

I'm trying to write the Cypher queries to resolve GraphQL queries, and would like to paginate (for example) the Forum -> Thread connection. The relationship is CONTAINS which holds an order property i.e. (f:Forum)-[:CONTAINS]->(t:Thread)

From the neo4j-graphql-js library I picked up on their usage of pattern comprehension to run an "inner query" on the child nodes. For example:

I have an application written in ReactJs, that is deployed on AWS amplify. It all works great but I'm struggling with something.

Whenever I refreshed on a certain path, for example www.domainname.com/path/path. It redirected me to www.domainname.com/index.html

I figured out that this had something to do with my redirects on AWS amplify.

So, I tried changing the 404 (Redirect) to 404 (Rewrite), which worked.

even though it worked, this gave me another problem. If I refresh the page on the example www.domainname.com/path/path again and I look at the network console in the browser. I see that page that loads gets an 404 Not Found error even though the page gets loaded.

This error causes annoying things for example I put my link in a powerpoint presentation, upon trying to open this. I get an error message that it cannot be found (404)

I don't get this error on localhost, only on my domains

Here is my routing in React

I'm doing a project of mine and I'm trying to return an Json object with an image and some other data to the client, is this possible? And if its not, if I return the image as a byte array or base64 would a frontender be able to convert it back to an actual image or the conversion should be done on my end?

I'm frontender and I do my first API with RBAC based on Express + MongoDB. I need to postprocess Role permissions which I've got by await function. Example (this code works great):

I'm trying to build a simple time series API that would do the following:

1. Everyday at 00h a CRON job goes to a facebook API and GET's multiple facebook pages fan counts, then saves them in mongoDB like this:

{ "_id" : ObjectId("5c13b3663b720419c7806a4f"), "name" : "PageName", "dateUpdated" : "2018-12-17T00:00:00.000Z", "likes" : [ { "date" : "2018-12-14T00:00:00.000Z", "value" : NumberInt(74154) }, { "date" : "2018-12-15T00:00:00.000Z", "value" : NumberInt(89154) }, { "date" : "2018-12-17T00:00:00.000Z", "value" : NumberInt(86745) } ] }

Everyday when CRON does its job, the "Likes" array gets updated with the like count of that day.

1. I query the API by passing a page name and date range for probably two days, and the API then returns me the difference in value and in percent between the two objects in "likes" array by the date range.

so I'd love to do a api call like this:

https://api.com/likes?name=PageName&from=2018-12-14&to=2018-12-17

and get a json resposne like:

{ before: 74154, now: 86745, change: 12.591, changePercent: +10% }

Is it possible to do this with mongo? I suppose aggregation is what I need? I'm fairly new with the database and the back-end javascript programming (I'm a frontender), so any help would be appreaciated.

BTW, is my schema design even correct? Should I create a mongoose scheme for the Page, then another scheme for the likes entry, and then ref the likes entry scheme in the page scheme?

If I'm being cofusing please just ask me for any info You need, I'll try to respond quickly.

Thanks!

(Non frontender here so excuse my total ignorance here)

I have a multipart form with a file selector, the form and the file should be sent to a POST endpoint in my backend.

How do I send this form "behind the scenes" so to say, without redirecting the entire browser tab to the target URL?

I've found this post: https://laracasts.com/discuss/channels/vue/submit-serialized-form-data-with-vue?page=1

But that does not address file inputs.

What would be the proper way forward?

I'm building a NodeJS platform that consist of several core 'parts' (users, messages and trading signals).

So my idea is to create microservices for each of them, and it works pretty well.. But I can't get my head around how to 'join' data between the microservices (I'm a frontender originally.....)

For example, I have 3 microservices.. Each with its own MongoDB, on its own machine complete isolated.. Imagine the common situation where the messages is retrieved from a single microservice, the message has a 'user_id' and I need to get the username and profilePicture to be combined in the retrieved message object..?

I read a lot about using Redis, but it seems like a 'messaging' service to me, not much of a 'combine' service.. Can anyone help me through the darkness??

Thanks!!

I know its a very general question... But I just can't get a grip of what the 'best practice' is when combining data of multiple micro services..
