    react-window

    react-window

    React components for rendering large lists and tabular data

    React window works by only rendering part of a large data set (just enough to fill the viewport). This helps address some common performance bottlenecks. It reduces the amount of work (and time) required to render the initial view and to process updates. It reduces the memory footprint by avoiding over-allocation of DOM nodes. react-window is a complete rewrite of react-virtualized. If react-window provides the functionality your project needs, it is strongly recommend that you use it instead of react-virtualized. ...

    Jest Puppeteer

    Jest Puppeteer

    Run your tests using Jest & Puppeteer

    ...A fix to this is to run your test serially when in a CI environment. Users have discovered that running test serially in such environments can render up to 50% of performance gains. Writing integration test can be done using Puppeteer API but it can be complicated and hard because API is not designed for testing. Debugging tests can be hard sometimes and it is very useful to be able to pause tests in order to inspect the browser. Jest Puppeteer exposes a method jestPuppeteer.debug() that suspends test execution and gives you the opportunity to see what's going on in the browser.
