Django2020 (vscode debug launch etc), url query parameter (dateStart/End), react hooks, material-ui, create-react-app (build)

TODO:

• local dockerized db for dev
• Use TypeScript on reactui
• Upgrade django, plotly version
• django production build, https://docs.djangoproject.com/en/3.0/howto/deployment/wsgi/

date from react pickerUI is GMT+0, https://developer.mozilla.org/zh-TW/docs/Web/JavaScript/Reference/Global_Objects/Date
So 2020-02-10 is 00:00 clock at GMT+0 but is 08:00 at GMT+8

build readme:

url example1(two servers case, ui is on http://localhost:3000):
http://localhost:3000/?timeStart=1580649114000&timeEnd=1581206400000
( 1580649114000 is unix timestamp and gotten from js date object)

url example2 (only django server case):
http://127.0.0.1:8000/?timeStart=1580649114000&timeEnd=1581206400000

django part:

class ChartView(TemplateView):
    template_name = "chart.html"

    def get_context_data(self, **kwargs):
        context = super(ChartView, self).get_context_data(**kwargs)
        if "timeStart" in self.request.GET:
            print("timeStart:" + self.request.GET["timeStart"])
        if "timeEnd" in self.request.GET:
            print("timeEnd:" + self.request.GET["timeEnd"])
