Extract information from various files stored in Firestore

I have been struggling to retrieve data from multiple documents despite numerous attempts. The screenshot below displays that I have a collection of 3 documents, and my inquiry is how to extract data from each of them.

Even though I used a foreach loop to iterate through all the documents, I face difficulty in retrieving data specifically from id RoKQBRcuaVfcGPKNswbx or idY8KbSQHcuxctJCJ1lWYH, as it automatically fetches the data of the last id only.

I am really in need of assistance. Thank you.

Answer №1

The snapshot object holds the data for all 3 documents within your collection. It is important to loop through each document and display the information in your HTML using the provided instructions.

db.collection("Policies List").get().then((snapshot) => {
  const documents = snapshot.docs //array of documents
  documents.forEach((doc) => {
    const docData = doc.data() //Data of that single document
    console.log(docData)
    renderToHtml() // Function that generates new HTML elements
  })
})

This approach ensures that new HTML elements are created for every document in your collection. The renderToHtml() function will include the necessary .innerHTML code. Be sure to check the console logs for a better understanding of the document structure.
