A built version of the application is already provided, to simply start it, run server.exe and open http://localhost:3000 on your web browser.
If you need to make changes to the displayed data in the chart navigate to frontend/src/App.js and find the data constant:
const data = [ { name: "Fri, 08 Mar 2019", missmatch: 0, uncorrected: 50, corrected: 50 }, { name: "Sat, 09 Mar 2019", missmatch: 0, uncorrected: 60, corrected: 40 }, { name: "Sun, 10 Mar 2019", missmatch: 0, uncorrected: 68, corrected: 38 }, { name: "Mon, 11 Mar 2019", missmatch: 0, uncorrected: 65, corrected: 40 }, { name: "Tue, 12 Mar 2019", missmatch: 0, uncorrected: 80, corrected: 30 }, { name: "Wed, 13 Mar 2019", missmatch: 0, uncorrected: 79, corrected: 29 }, { name: "Thu, 14 Mar 2019", missmatch: 0, uncorrected: 55, corrected: 45 } ];
If you need to preview changes while altering data you can run a development server using: npm start
After changes have been made, make sure you have NPM installed and run this command: npm run build
Once the build is finished, relaunch server.exe and new data will be live.
