The process of ordering awaits using an asynchronous method

async fetchAndStoreRecords(): Promise<Records[]> {
    this.subRecords = await this.afs.collection<Records>('records')
        .valueChanges()
        .subscribe((data: Records[]) => {
            console.log('log before data saved');
            this.records = data as Records[];
        });
    console.log('log before return');
    return await this.records;
}

My issue lies in the order of execution of this code. The log before data saved appears after the return statement, causing a delay in saving the data. I am seeking a solution to ensure that the function returns the records promptly and stores them in my this.records array.

Answer №1

If you're looking to retrieve data from a single query, it's best not to utilize valueChanges(), as it does not return a promise. valueChanges is typically used when you want to establish a listener for data that may change over time.

In your situation, consider using get() instead, which provides a promise that resolves with the results of the query, as demonstrated here.

await this.afs.collection<Records>('records').ref.get()
