CORS Proxy which can take multiple url requests at a time
How this script works:
Most cors proxy available at Github (such as CORS-anywhere) can take only single url at a time, but this can take multiple urls at a time
This script returns consolidated responses with href link with class multicorsproxy at the top of the response and a boolean value inside the <a> tag, which indicates the response was successful or not.
On errors it will add an <a> element with class multicorserror and error string inside it
This script will only return responses whose content-type header starts with text, you are free to fork this code or copy the code from here and edit it to allow more content-type headers.
Benefits:
No matter how many urls you request at a single time, it will be counted as just 1 request by cloudflare, so you can fetch like 20 urls at a time and cloudflare will count as one request
Note: Cloudflare workers can support upto 50 url requests at a time from this script
Steps to setup multi-cors-proxy at cloudflare:
- Register at here
- Create a new worker and click on quick edit
- Paste this code in there and click save and deploy
- You will get a url something like: https://misty-tooth.username.workers.dev note it down.
Below Usage example in JavaScript:
Usage:
// Array to store the list of urls to fetch, max 50 urls at one time
var arr = ["https://developer.mozilla.org/en-US/docs/Web/API/Request","https://en.wikipedia.org/"]
// Paste the url which you got in step 4
fetch('https://misty-tooth.username.workers.dev',{
method: 'POST',
body: JSON.stringify(arr)
})
.then(response => response.text())
.then(data => console.log(data))Output in Console:

<p>The <b><a href="/wiki/Large_red_damselfly" title="Large red damselfly">large red damselfly</a></b> (<i>Pyrrhosoma nymphula</i>) is a species of <a href="/wiki/Damselfly" title="Damselfly">damselflies</a> belonging to the family <a href="/wiki/Coenagrionidae" title="Coenagrionidae">Coenagrionidae</a>. Although called large, it is only 35 mm (1.4 in) long and 15 percent larger than the <a href="/wiki/Small_red_damselfly" title="Small red damselfly">small red damselfly</a>. This specimen, a mature male photographed at <a href="/wiki/Dry_Sandford" title="Dry Sandford">Dry Sandford</a> in <a href="/wiki/Oxfordshire" title="Oxfordshire">Oxfordshire</a>, England, is a mature male; immature individuals of both sexes have yellow shoulder stripes rather than red ones. Mature females come in three different colour forms, but all have yellow bands round their abdominal segments. This species occurs mainly in Europe and is on the wing from April or May onwards. The <a href="/wiki/Larva" title="Larva">larvae</a> are found in ponds, lakes and ditches, and take two years to develop before they emerge as adults.

<p>The <strong><code>Request</code></strong> interface of the <a href="/en-US/docs/Web/API/Fetch_API">Fetch API</a> represents a resource request.</p>
<p>You can create a new <code>Request</code> object using the <a href="/en-US/docs/Web/API/Request/Request"><code>Request()</code></a> constructor, but you are more likely to encounter a <code>Request</code> object being returned as the result of another API operation, such as a service worker <a href="/en-US/docs/Web/API/FetchEvent/request"><code>FetchEvent.request</code></a>.</p>

<h2 id="Examples">Examples</h2>
<p>In the following snippet, we create a new request using the <code>Request()</code> constructor (for an image file in the same directory as the script), then return some property values of the request:</p>
<pre class="brush: js">const request = new Request('https://www.mozilla.org/favicon.ico');
const URL = request.url;
const method = request.method;
const credentials = request.credentials;
</pre>
<p>You could then fetch this request by passing the <code>Request</code> object in as a parameter to a <a href="/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch"><code>WindowOrWorkerGlobalScope.fetch()</code></a> call, for example:</p>
<pre class="brush: js">fetch(request)
.then(response => response.blob())
.then(blob => {
image.src = URL.createObjectURL(blob);
});</pre>
<p>In the following snippet, we create a new request using the <code>Request()</code> constructor with some initial data and body content for an api request which need a body payload:</p>

const URL = request.url;
const method = request.method;
const credentials = request.credentials;
