I want to be able to load a blog post when a user is directed to /feed/:id and I want this page to load in Angular.js. Basically I want Node to pass the post title, content, etc. to the Angular template in JSON format (post.html) and for Angular to use the JSON attributes of the post (post.name, post.content, etc...).
I know how to build the API on the Node side to get this data from a MongoDB datastore but I'm not entirely sure how to pass it on to the Angular controller once I have it in Node.

I am used to creating webapplications with Wicket. There it is possible to generate a HTML page using POST, receiving a large JSON from the client (browser) to generate some charts. This can be done for example with CURL.
In Angular, I could not find a similar approach.
What is the recommended way to render a chart based on the JSON that a browser provides? An URL parameter is not really the way to go as the URL length is limited.
I can think of a work-around wheren I first post the data to some webservice, receive an id, and then pass that id to an URL in Angular, but that seems a lot of work for something simple :)
I am new to Django. I have a few independent dropdown boxes. Now I have to get data from the backend in JSON and parse it for each dropdown boxes. How do I do this? How do I bring JSON via URL? how should I make use of Ajax methods here?
Basically, I want to use Ajax method calls and JSON bind data to ui.
I recently started learning to create restful web services with spring framework.
all the course is using postman to send requests but I want to send requests from a web page, like creating a table and send firstName and lastName from the HTML file (from the view, .jsp file) and store it in the database.
everywhere I lookt, they all saying the standard file to send to or retrieve from a restful endpoint is JSON, not HTML.
and from what I see #RequestBody only accepts JSON or XML, not HTML inputs.
I tried sending data from HTML(Method = "POST") to a #PostMapping method of my restful web server, to create something and store it in the database but an exception that says "Content-type not supported" was thrown.
I have lots of questions about this, and they all point to the same thing, Not understanding the whole thing.
what's the point of creating restful web service for the back end of a website, when HTML doesn't support put and delete requests and standard file that everyone uses to get requests from the client is JSON, not HTML.
can a web page (HTML) generate it's content to form a JSON file that is being sent back from a restful server?
how can I generate a JSON file from the inputs in HTML file and send it to the restful #PostMapping method?
there are two things that I should mention here,
I don't know much about creating web pages (HTML) I have only been creating very simple HTML files to help me create and test a back end server.
I searched so many questions before I post this one, and none of them helped me.
I will try to answer your questions
First, you need to understand what rest is it is a Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating Web services.(https://en.wikipedia.org/wiki/Representational_state_transfer)
so we follow a set of standards to make things easier.
Now coming to your actual question why JSON and not HTML because these are not only consumed from HTML these are consumed by different apps or services and json is a more lightweight and less verbose format, and it’s easier to read and write as well. In most cases, it’s ideal for data interchange over the internet
and we can use it with front end libraries like react , jquery or vanilla javascript to render the content in HTML from JSON without any changes to the API and also use a Backend web service to use this API.
https://api.jquery.com/jQuery.getJSON/
https://reactjs.org/docs/faq-ajax.html
for the other two questions basically You don't have to generate JSON file to call the rest API from HTML and render the content in HTML Instead you can use front end libraries like Jquery, React, Angular or use vanilla javascript to render content and call the rest API.
My service response is json array and i want to parse it and make as many embedded html forms as many json elemnts i have in my json array.
and here are several subjects i am intersted in:
is it possible to invoke and parse rest service inside camunda embedded form ,How can i do it?
I am using Contentful CMS - when my JavaScript app loads, I retrieve all the articles/entries during app initialization. I then want to query this local json object without doing futher Http calls to Contentful
Each entry of the 'items' array will have 'id' links to categories/authors/assets etc which will be in the returned Json.
Is there a JavaScript library or API I can use to query this Contentful json data locally on the client side?
You probably want to look at normalizr for that. The idea is to transform JSON into something that you can access by entity type + entity id, so it 'feels' more like querying a relational database.
