Hi Kiflemariam,
You should not cast all things to promises, that makes your life so much
harder.
newSetupApp(idToken) {
const keyHandler = async key => {
if (key) {
await this.db.setKey(key).catch(() => console.log('setDb Failed'));
await this.db.createData(key).catch(() => console.log('createDb Failed'));
}
console.log('done with promises');
return key;
};
this.apiService
.api1(idToken)
.pipe(
/** only proceed if the result is 'ok */
filter(result => result.includes('ok')),
switchMap(() => this.apiService.api2()),
/** the whole handling of the api2 result is a side-effect */
switchMap(keyHandler),
switchMap(() => this.apiService.api3())
)
.subscribe({
next(result) {
console.log('result', result);
},
error(err) {
console.log('an error occured', err);
}
});
}
Should do what you need. A working version is available on stackblitz
