<h2>Übung 15: Produkt-Verkaufstabelle</h2>
|
||||
|
||||
<p>
|
||||
Es handelt sich um eine einfache React-App, die eine Liste der Produktverkäufe in einer Tabelle anzeigt, die
|
||||
von einer API aufgerufen wird. Um die Übung zu vereinfachen, verwenden wir im Projekt lokale Daten, die aber
|
||||
eine externe API anregen.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Du wirst jedoch feststellen, dass beim Starten der App sofort eine leere Seite mit Fehlern in der Konsole
|
||||
angezeigt wird. Du kannst die Fehler überprüfen, indem du die Konsole öffnest. Die Aufgabe lautet wie folgt:
|
||||
</p>
|
||||
|
||||
<ol class="list">
|
||||
<li>
|
||||
Untersuche die Fehler und debugge die Anwendung nur mit dem VSCode-Debugger. Das heißt, du darfst vorher
|
||||
keine Dateien bearbeiten. Verwende das Variablenfeld im Debugger, um die Variablen zu bearbeiten.
|
||||
</li>
|
||||
|
||||
<li>
|
||||
Nachdem du die Anwendung erfolgreich debuggt hast, behebe den Fehler, indem du die Funktion fetchSalesData
|
||||
änderst. Ändere nicht die Datendatei selbst. Das ist eine gute Übung, wenn du eine API aufrufst, die
|
||||
manchmal fehlerhafte Daten zurückgibt.
