Trying to implement async await for executing an http request prior to running other code. Specifically, wanting to delete a collection in the mongodb database before proceeding with additional tasks. This is what has been attempted:
app.component.ts:
async deleteRiskRatingData2() {
await this.saveInformationService
.deleteRiskRatingInformation()
.subscribe((data: string) => {
console.log('Deleting risk Rating');
console.log(this.riskRatingTable);
});
console.log('TASKS TO BE EXECUTED AFTER DROPPING COLLECTION');
}
save-information.service.ts
deleteRiskRatingInformation() {
console.log('INIDE deleteRiskRatingInformation INSIDE SAVE-INFORMATION.SERVICE');
return this.http.get(`${this.uri}/dropRiskRatingCollection`);
}
On the server side:
server.js
router.route('/dropRiskRatingCollection').get((req, res) => {
RiskRating.remove({},(err) => {
if (err)
console.log(err);
else
res.json("Risk Rating Collection has been dropped!");
});
});
The result:

Expected Async/Await implementation to execute:
console.log('TASKS TO BE EXECUTED AFTER DROPPING COLLECTION');
This did not occur as intended. Confusion surrounds why this is happening. Is there a flaw in the logic? And how can the goal be accomplished?
Thank you!
