Making AJAX call from chrome extension to Meteor web app - ajax

Hi I have made a web app to practice Meteor and am now trying to make a companion chrome extension. I am having difficulty finding resources on how to make AJAX calls to my meteor app/mongodb.
An example of what I am trying to do is find specific words on a webpage and search them in my mongodb.
Any resources or information on how to best do this would be appreciated.

I suppose you know how to make Ajax call from client. So you are having difficulty in building a REST API in Meteor. Although it is not recommended to build a REST API with Meteor, you can still do it. If you use case just require a REST API and does not have much to do with reactivity, I think you should not go with Meteor, just Node and Express should be fine.
But if you really want to use Meteor, here is the solution: Meteor has a package named webapp which let you handle HTTP requests, that is enough for building a simple REST API. If you API is more complex, check out this community package nimble:restivus it has a better API and useful functions

How to set up authorization using js-SSR and SPA?

I want to develop my own single page web application (SPA) to get to grips with the modern and highly fluid world of web development. At the same time, I would like to use the page rendering technology (SSR) with built in data into html. However, there is an authorization problem.
Suppose that the user has already logged into the account before, as I imagine re-opening the site:
First request: the client makes a request to the frontend server along with identification and authorization data (for example, user id and token; the only option is to save them in cookies), the frontend server makes a request to the api server, transferring these service data, then the api server gives the information about the user and the content of the current page (in the same json), the frontend server renders this into a finished page and delivers it to the client.
Subsequent requests: the client directly addresses the api server, transferring the same (or updated after the first request) authorization data, receives json and processes it independently.
Actually, I want to move on to the question. Do I understand this interaction correctly? Can you do it differently / better? Are there tools that allow, for example, to use the components of the frontend framework as components of the MVC backend framework, so that one server does the rendering without unnecessary requests? Or a unified tool that includes the same coding for the frontend and backend to solve these problems? I will say right away that I would not like to write a backend in JS.
I can roughly imagine how you can get by with one request when using AngularJS (with a module for single page applications) and any backend MVC framework; although there will not be a full-fledged render, but search robots will not have to wait for my first fetch, since the data will be delivered initially, for example, through the data attribute. But in this case, I plan to choose Svelte (Sapper) and Ruby on Rails as the stack, although I think this is not important.
Thank you for your attention to the question!

If that's what you want you can install a frontend framework in Rails using webpacker. After that you will have a folder in your rails project that will contain your Svelte components. Then you import Svelte components in erb templates and pass data as props.
I have tried that approach but personally I prefer a separate frontend and backend talking through API calls. Then in your frontend you need something like Sapper if you need SSR. With webpacker you don't(assuming you mostly use Rails for routing).
If you are worried about authorization it's not really hard to implement. And after login you can store user info on local storage for instance for subsequent requests. But of course if you install with webpacker it's all done within Rails hence it's easier.
From my experience, using webpacker it's easy and quick in the beginning but you are more likely to get headaches in the future. With separate backend and frontend takes a bit more work, especially in the beginning, but it's smoother in the long run.
This helped me set the authentication between rails api and vue frontend.
So, if you wish to separate them, just install Rails as API only and I suggest you to use Jbuilder to build your jsons and serve them to the frontend as you need them.

Consuming Laravel Passport API with javascript (React + Axios) from another application

I have managed to make run Laravel 5.4 and implemented the API Authentication (Passport).
What I would try to achieve is to make this as my API server and build React applications that would interact on this API.
Does this mean I have to make routes on routes\api.php?
Let's say I have a React app name requestform on development and running on http://127.0.0.1:8080. How will I consume an api route with axios or jquery?
I can't seem to make the correct keyword to search on google and all the samples I can get are the ones that the API and the javascript application is on the same domain.
This post may have been answered by now. But if not then...
I think you are in the right track..
Does this mean I have to make routes on routes\api.php?
Yes. Your API routes will depend on this file.
Let's say I have a React app name requestform on development and running on http://127.0.0.1:8080. How will I consume an api route with axios or jquery?
Make sure your API Server is running, say it's on http://server.dev, you can consume the API in another app by http://server.dev/api/[your-routes].
I can't seem to make the correct keyword to search on google and all the samples I can get are the ones that the API and the javascript application is on the same domain.
This is a matter of what front-end programming you know. You can use any javascript knowledge to consume your own API with the same domain. There is already a Vue integration packaged in Laravel 5.4+ or just plain vanilla javascript or jQuery.

Advantages of using APIs wrapped with .NET in Xamarin

Around a year ago I made an iOS application that finds restaurants near your location of any type and displays information about them. I made a web service call using the FourSquare api to get all the data which was returned in json format and then I parsed it and displayed the information on the UI of the app. Now I want to make an android application using Xamarin.Android since I am learning working with Xamarin studios and C#. When I make a Xamarin.Android application and go to packages then add packages I see there is a Foursquare api package that has a .NET wrapper around it. Here is the website url:
https://www.nuget.org/packages/Foursquare.Api/
So my question is how does this work? Does adding this package mean I don't have to make a web serivce call anymore, instead all the data is stored inside this package and I just have to get all the data the same way I get information from a local database? What are the advantages of using this package instead of just making a web service call to Foursquare?
Think of it this way:
This Foursquare API is simply a .NET wrapper of the web service that you want to use. Thus, somebody has gone ahead and done all of the hard work for you so you can simply consume the returned data in your applications.
What does this mean for you?
Well it means that you don't have to write any REST consumption code and you can focus more on the actual application and any business logic that you need to implement based on the Foursquare objects.
To not confuse any further, this data would come the same way as if you wrote your own web service to access the data from the Foursquare API endpoint.
Advantages:
Already written for you
You don't need to know your way around their REST API
Usually follows best practices per language so it's easy to consume (Objects created, methods, etc)
Disadvantages:
REST endpoint might be updated and not reflect in the package until it's updated
Any bugs/issues in the framework can be hard to workaround if the project is not open source
Could be a lack of documentation on how to use the wrapper

Django rest framework + ionic2 + django channels

I want to develop real time native application and considering using Django as backend and ionic2 as frontend. But through the research i realize that websocket is needed for the app to be real-time. And django channels is the option.
The question is "is it possible to combinate django rest framework, ionic2 and django channels altogether?" And additionally if I try to implement push notification using cordova plugin, could it be also work altogether? I know this question is quite bad but I am quite a beginner so i want to know before trying this approach..
any advice will be great for me, Thanks buddies in advance!
Yes, it is.
Ionic is going to be only a consumer of your Django-rest-framework API and your Django services. In other words, the front-end can be in any technology you want.
On the other side, Django-rest-framework + Channels work perfectly together. They are supposed to be. I've recently built a project with those technologies and I can guarantee that there is a perfect separation between the asynchronous processes and the typical Django HTTP runserver process.

Phonegap and Django Authentication

I am in the middle of building a PhoneGap (Cordova) app which I would like to be able to talk to a Django site of mine. The steps needed to get the app working are:
Authenticate the user (stay logged-in across app restarts) (e.g. get session cookie from Django for communication with the service - where to store?). Note: The Django endpoint uses https.
When app receives push notification load some data from my django site.
Make selection on data and submit response back to my django site (will need the csrf token?)
I was able to sort out the push notifications but now I am wondering which solution would work best for the communication with Django.
As I understand there are two possible approaches:
Either to implement a REST service with something like tastypie or
try to setup the communication via ajax (e.g. jQuery)
At the moment I am thinking that going simply ajax might be the best approach since the app is fairly small and there are no additional requirement for a REST API.
It would be great if anyone could give me any pointers on how to solve this or share some experiece / code. Especially the steps of the authentication process are unclear to me.
I am not sure if this is still an open question but it is sure an interesting one.
I would strongly suggest on using the django-tastypie and you could start by using the docs which are indeed a great point of reference.
My experience until now has shown that I should always start by making my api clear(and rest) than choosing an easier faster solution(e.g. ajax) because if your app is a successful one, frameworks like tastypie help you scale.
The authentication process is pretty straightforward if you choose the basic one.
You just ask for the user credentials and there are many clients implementing the client side basic auth.
Fortunately, tastypie supports more than this. For example, the api authentication and you could read more here.
If you need anything else, please let me know.

Michael.
