Angular Firestore: Creating and Saving Data under ID Field of Type Map

When working with Angular Firestore, you may come across a scenario where you need to create and save data under an ID field of type map. This can be a bit tricky, but fear not! In this blog post, we will explore different solutions to tackle this problem.

Solution 1: Using the set() method

The first solution involves using the set() method provided by Firestore. This method allows you to set the value of a document with a specific ID. To save data under an ID field of type map, you can follow these steps:

1. Create a reference to the document using the collection() and doc() methods.
2. Create a map object with the desired data.
3. Use the set() method to save the map object under the ID field.

Here’s an example code snippet:

import { AngularFirestore } from '@angular/fire/firestore';

// ...

constructor(private firestore: AngularFirestore) {}

saveData() {
  const docRef = this.firestore.collection('yourCollection').doc('yourDocument');
  const data = new Map();
  data.set('yourIDField', 'yourData');
  docRef.set({ yourIDField: data });
}

Solution 2: Using the update() method

If you prefer to update an existing document instead of creating a new one, you can use the update() method. This method allows you to update specific fields of a document, including the ID field of type map. Here’s how you can achieve this:

1. Create a reference to the document using the collection() and doc() methods.
2. Create a map object with the desired data.
3. Use the update() method to update the map object under the ID field.

Here’s an example code snippet:

import { AngularFirestore } from '@angular/fire/firestore';

// ...

constructor(private firestore: AngularFirestore) {}

updateData() {
  const docRef = this.firestore.collection('yourCollection').doc('yourDocument');
  const data = new Map();
  data.set('yourIDField', 'yourUpdatedData');
  docRef.update({ yourIDField: data });
}

Conclusion

Working with Angular Firestore and saving data under an ID field of type map can be achieved using the set() or update() methods. By following the steps outlined in this blog post, you can successfully create and save data under the desired field. Remember to adapt the code snippets to your specific use case.

Happy coding!
