Migraine Tracker – Create Frontend – Brian Hafner Tech Blog

Firstly, I use create-react-app to create my project files. But then I’ll delete everything in src folder and start from scratch to get the things I want to have in it.

In preparation for some packages I’ll need later on, I “yarn add” (same as “npm install”, using yarn the following packages: redux, redux-promise, react-redux, and react-router-dom.

I also want to use the Material UI framework, so I’ll yarn add “@material-ui/core”.

I also need to yarn add ‘redux-thunk’.

I had to add a sort function to my map function in order to get the headache entries to display in descending order of date.

    <TableBody>
          {myHeadaches
            .sort((a, b) => (a.date < b.date ? 0 : -1))
            .map(n => {
              return (
                <TableRow key={n._id}>
                  <TableCell numeric>{n.date}</TableCell>
                  <TableCell numeric>{n.painLevel}</TableCell>
                  <TableCell numeric>{n.comment}</TableCell>
                  <TableCell numeric>
                    <span>
