    HLS.js

    HLS.js

    HLS.js is a JavaScript library that plays HLS in browsers

    HLS.js is a JavaScript library that implements an HTTP Live Streaming client. It relies on HTML5 video and MediaSource Extensions for playback. It works by transmuxing MPEG-2 Transport Stream and AAC/MP3 streams into ISO BMFF (MP4) fragments. Transmuxing is performed asynchronously using a Web Worker when available in the browser. HLS.js also supports HLS + fmp4, as announced during WWDC2016. HLS.js works directly on top of a standard HTML<video> element. HLS.js is written in ECMAScript6 (*.js) and TypeScript (*.ts) (strongly typed superset of ES6), and transpiled in ECMAScript5 using Babel and the TypeScript compiler. Webpack is used to build the distro bundle and serve the local development environment.

    Mock Service Worker

    Mock Service Worker

    Seamless REST/GraphQL API mocking library for browser and Node.js

    Mock by intercepting requests on the network level. Seamlessly reuse the same mock definition for testing, development, and debugging. A dedicated layer of requests interception at your disposal. Keep your application's code and tests unaware of whether something is mocked or not. Request the same production resources and test the actual behavior of your app. Augment an existing API, or design it as you go, when there is none. Use Express-like routing syntax to capture outgoing requests. Parameters, wildcards, regular expressions, mocking has never been easier. Browser usage is what sets Mock Service Worker apart from other tools. Utilizing the Service Worker API, which can intercept requests for the purpose of caching, Mock Service Worker responds to captured requests with your mock definition on the network level. This way your application knows nothing about the mocking.

    Ionicons

Also note that only visible icons are loaded, and icons which are "below the fold" and hidden from the user's view do not make fetch requests for the svg resource. If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary.

    Got

    Got

    Human-friendly and powerful HTTP request library for Node.js

    Got implements RFC 7234 compliant HTTP caching which works out of the box in-memory and is easily pluggable with a wide range of storage adapters. Got uses Keyv internally to support a wide range of storage adapters. For something more scalable you could use an official Keyv storage adapter. Hooks allow modifications during the request lifecycle. Hook functions may be async and are run serially. Got will make no further changes to the request before it is sent. This is especially useful in conjunction with got.extend() when you want to create an API client that, for example, uses HMAC-signing. You can override the request function by returning a ClientRequest-like instance or a IncomingMessage-like instance. This is very useful when creating a custom cache mechanism. The response object will typically be a Node.js HTTP response stream, however, if returned from the cache it will be a response-like object which behaves in the same way.
