My goal is to send an Http Post request (Registration form) using Angular, have it processed in the API, and if any errors occur like Please enter a username..., I want to return an error message to the client. Below is the Angular code for reference. Thank you!
Angular:
sendData(data: {username: string, password: string, bdate: Date}){
let headers = new HttpHeaders({
'Content-Type': 'application/json', });
let options = { headers: headers };
let JsonData:any = JSON.stringify(data);
console.log(JsonData)
this.http.post('http://localhost:3000/register', JsonData, options)
.subscribe((res) => {
console.log(res)
})
}
