I develop SPA calls analytics applications with the React, redux, flowType stack. I'm collecting a webpack with a babel with dynamic imports. The unit of tests is jest, enzyme, react-dom test utils, test cafe for regress testing.The application for the functionality is somewhat reminiscent of Yandex.metrics, only with data on calls. It is possible to configure reports for yourself with a bunch of slices, metrics and filters.The main complexity of the project is big data, processing over 100k calls on the frontend (sorting, filtering, aggregating data for groups, recursive grouping, detailed profiling). In the project we decided to render processing for visual display on the frontend, the backend gives a clean array of calls with parameters by dates.Interesting project:- The table with virtual render, respectively, without brakes and lags we see at least 100, even +100500 calls.- The module for managing the voice service, using the SpeechRecognition API for word recognition.- Dynamic chart with aggregated data using highcharts.- Custom audio player using Web Audio Api, respectively with audio without a tag, but using AudioContext- Tag cloud, with position distribution by weight. For implementation I used d3- And a lot of trivia, such as highOrder component privateRoute, with verification for authorization, which is built on jwt token. The construction of a spectrogram on the SVG on an array of points.Well, of course layout, SCSS, Flexbox, Grid, BEM and other modern buns.
