function acceptsEncodings
import { acceptsEncodings } from "https://deno.land/x/fathym_eac_runtime@v0.0.140/src/src.deps.ts";

Returns an array of content encodings accepted by the request, in order of preference. If there are no encoding supplied in the request, then ["*"] is returned, implying any encoding is accepted.

Examples

Example 1

import { acceptsEncodings } from "https://deno.land/std@0.224.0/http/negotiation.ts";

const req = new Request("https://example.com/", {
  headers: { "accept-encoding": "deflate, gzip;q=1.0, *;q=0.5" },
});

acceptsEncodings(req); // ["deflate", "gzip", "*"]

Returns

string[]

For a given set of content encodings, return the best match accepted in the request. If no content encodings match, then the function returns undefined.

NOTE: You should always supply identity as one of the encodings to ensure that there is a match when the Accept-Encoding header is part of the request.
