The Process

To satisfy the criteria, we had to:

• Install inquirer package
• Install path package
• Install express package
• Refractor CSS file to give HTML nootbook theme
• Code server.js to initialize applications' backend

Specific functions of server.js:

Create new note along with new object and alert terminal

app.post("/api/notes", (req, res) => {
    let savedNotes = JSON.parse(fs.readFileSync("./db/db.json", "utf8"));
    let newNote = req.body;
    let uniqueID = (savedNotes.length).toString();
    newNote.id = uniqueID;
    savedNotes.push(newNote);

    fs.writeFileSync("./db/db.json", JSON.stringify(savedNotes));
    console.log("A new note has been saved: ", newNote);
    res.json(savedNotes);
})

Delte note along with object and alert terminal

app.delete("/api/notes/:id", (req, res) => {
    let savedNotes = JSON.parse(fs.readFileSync("./db/db.json", "utf8"));
    let noteID = req.params.id;
    let newID = 0;
    console.log(`Deleting note with ID ${noteID}`);
    savedNotes = savedNotes.filter(currentNote => {
        return currentNote.id != noteID;
    })
    
    for (currentNote of savedNotes) {
        currentNote.id = newID.toString();
        newID++;
    }

    fs.writeFileSync("./db/db.json", JSON.stringify(savedNotes));
    res.json(savedNotes);
})

The Result

After dynamically coding our backend application using Express.js along with refractoring CSS and HTML, we were able to provide a fully functional fullstack application that allows our client to write, store, retrieve, and delete notes.
