When I access the typeform API via browser using $.get or superagent or request or axios, I get the error No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.
However, when I user cURL or HTTPIE or Postman to make the same request, it is successful everytime. How to solve this behaviour and how to implement the client version?

How can I send a CORS request using Curl? To make a CORS request using Curl, you need to pass an Origin HTTP header that specifies the origin of the request (domain, scheme, or port) other than the destination server address, and optionally the required HTTP methods and response headers.
CORS is a security mechanism built into (all) modern web-browsers (yes! into your web browser! That’s why your curl calls works fine). It basically blocks all the http requests from your front end to any API that is not in the same “Origin” (domain, protocol, and port—which is the case most of the time).

Now, how does this mechanism work? Let’s say you have an ‘upload’ button in the UI that suppose to upload some form of data to the API.
CORS provides a number of different mechanisms for limiting JavaScript access to APIs. It is often not obvious which mechanism is blocking the request. We are going to build a simple web application that makes REST calls to a server in a different domain.
CORS is enforced client side by your browser. If you are not making the request with a browser CORS is not enforced.
