A Deno module to extend fetch.

This project is inspired from:

• Deno - Standard Library - Async
• jhermsmeier/node-http-link-header
• node-fetch/node-fetch
• octokit/plugin-paginate-rest.js
• octokit/plugin-retry.js
• thlorenz/parse-link-header

🌟 Feature

• Cache suitable Request-Responses to reduce network usage and response time.
• Retry on failure requests, obey the response header Retry-After or a fallback random-able interval.
• Simplify paginate requests.

ℹ️ Notice: Although it is recommended to import main module with path mod.ts in general, it is also able to import part of the module with sub path if available, but do not import if:

• it’s file path has an underscore prefix (e.g.: _foo.ts, _util/bar.ts), or
• it is a benchmark or test file (e.g.: foo.bench.ts, foo.test.ts), or
• it’s symbol has an underscore prefix (e.g.: export function _baz() {}).

These elements are not considered part of the public API, thus no stability is guaranteed for them.
