How to access data ID in fIrebase

Time:01-11

I am working with Firebase Firestore using Nuxt js and I want to retrieve data from my database. I am using firebase with NuxtFirebase, the official plugin for firebase.

I need to access the ID property from my firebase database

Here is my store

const actions = {

  // The Post list API 
  async postList({ commit }) {
    try {
      const req = await this.$fire.firestore.collection('Post').get()
      const posts = req.docs.map((doc) => doc.data());

      console.log(posts)
      commit("SET_POST", posts)

    } catch (e) {
      console.log(e)
    }
  }
};


export default {
  state,
  getters,
  mutations,
  actions,
}

Looking at my console I get the following data

[
    {
        "title": "Bitcoin is the Detector of Imbeciles",
        "created_at": {
            "seconds": 1672921367,
            "nanoseconds": 80000000
        },

    },
    {

        "content": "I often got asked how a product manager could get promoted to a more senior level. The truth is, getting a promotion is often a complicated game.

        "tag": "Business"
    },
    {
        "content": "ChatGPT is blowing up. Twitter is inundated with screenshots of the app, coding sites like Stack Overflow are already banning answers produced with it, and over 1 million people have played with it. It’s a sensation.  As a professional AI researcher, I wouldn’t have called that. ChatGPT is trained specifically to act as a chat bot, but fundamentally it’s using the same GPT-3 technology that’s been available for over two years now.",

    }

I need to access the ID

CodePudding user response:

The req is a QuerySnapshot and every doc in the map is a QueryDocumentSnapshot that has id property. Try:

const posts = req.docs.map((doc) => ({ id: doc.id, ...doc.data() }));
console.log(posts)
