Add option to export as CSV

[EwanRoycroft]

It would be useful to be able to export as a CSV to share with healthcare professionals.

I've made a node script to do this:

const converter = require("json-2-csv");
const fs = require("fs");

const input = require("./backup20230818T2113110100.json");

const flat = [];

const newRow = (date, time, logType, details) => ({
    date,
    time,
    logType,
    details,
});

for (const day of input?.days) {
    // TODO: symptomOverviews
    for (const symptom of day.symptoms) {
        for (const log of symptom?.logs) {
            flat.push(
                newRow(
                    day.date,
                    log.time,
                    "symptom",
                    `${log.key}, intensity: ${log.pain}/5`,
                ),
            );
        }
    }
    for (const log of day.logs) {
        flat.push(newRow(day.date, log.time, "note", log.key));
    }
    for (const med of day.meds) {
        flat.push(newRow(day.date, med.time, "medication", med.key));
    }
    for (const meal of day.meals) {
        flat.push(
            newRow(
                day.date,
                meal.time,
                "meal",
                meal.detail ? `${meal.key}. ${meal.detail}` : meal.key,
            ),
        );
    }
    // TODO: wakeUp and goToBed
}

flat.sort((a, b) => {
    const dateTime = (n) => new Date(`${n.date}T${n.time}:00Z`);
    return dateTime(b) - dateTime(a);
});

const output = converter.json2csv(flat);

fs.writeFileSync("./diary.csv", output);

To use, save the backup from the app, and copy it to your working folder as backup.json. Save the script above as convert.js.

Then, run:

npm install json-2-csv@5.0.1
node ./convert.js

The output will be saved as diary.csv.
