Grunt: Very slow copy:js task on watch #8425
Labels

We are currently looking into improvements to the build tools. It should be possible to skip the copy:js task and reduce the build time to a few seconds every time a change is made. |

This shocked me because it wasn't like this last I checked. This is caused by the fact that we are now bundling MathJax as a backup. Perhaps MathJax should be excluded from |

Drastically reduces MathJax's burden on the build: * Brings a huge speed boost to Grunt's "copy:js" task (from ~13 to ~2 seconds) * Reduces MathJax's compiled size down from ~25 MB (1,347 files/809 folders) to ~1 MB (24 files/5 folders) * Almost halves the production dist folder's size (from ~55 MB to ~31 MB) Related changes: * Disabled MathJax's context menu * Added an ES6 polyfill for IE11 support * Added extra line comments to give more context about how the polyfills are loaded in * Changed the MathJax fallback test to look for a configuration option we're not customizing * Updated the documentation's known issues section: * Changed it into an unordered list * Replaced mentions of IE7-9 support with Chromium and IE11 * Removed mention of SVG support * Added an item about IE11 only being supported in internet-connected networks (due to its ES6 polyfill) * Removed items specific to IE7-8 Notes: * Disabling MathJax's context menu has the following impacts: * Works around MathJax 3.x's missing i18n support * Makes MathJax more closely mimic native MathML implementations (i.e. scraps bells and whistles that go beyond being a polyfill) * Removes some accessibility/usability enhancements that were present in WET's MathJax 2.x implementation (e.g. focusing on expressions, double-click to zoom). But it's not a huge loss since those enhancements don't exist in native MathML implementations. Visually-hidden MathML markup is still provided for ATs that support it. * Prevents users from accessing options that are excluded from WET's local copy of MathJax (e.g. "Math Settings - Math Renderer - SVG") * IE considerations: * Breaks compatibility with older versions of IE (older than IE11) * IE11 will only work if internet access is available * The IE11 ES6 polyfill won't interfere with other browsers. Its CDN (polyfill.io) serves a hollow JS file to browsers that natively support ES6. * Somewhat alleviates wet-boew#8425 (could still be improved by removing MathJax from the "copy:js" task) * Fixes wet-boew#8769

The copy:js task is greatly slowing down the build each time I make a change to a js file. (On a Surface Book i7, 16GB RAM, NVME SSD) Can this be sped up by keeping a cache of these 802 directories and 1384 files, and only updating the ones that have changed?
