I Don't want to make checks as if (!isPresent) then do this ....
Is their any way to bypass all the then when my work is complete
var isPresent=false;
myPromise
.then((employee) => {
if (employee) {
// throw 'employee already exist';
isPresent = true;
return res.data(mapper.toFullModel(employee));
}
return model;
});
.then(model => {
if (!isPresent) {
return new db.employee(model).save();
}
})
.then(employee => {
if (!isPresent) {
employee.token = auth.getToken(employee);
return employee.save();
}
})
.then(employee => {
if (!isPresent) {
res.data(mapper.toFullModel(employee));
}
})
.catch(err => {
res.failure(err);
});
You can rewrite your promise chain so the second part of it gets nested:
myPromise.then(employee => {
if (employee) {
return res.data(mapper.toFullModel(employee));
}
return new db.employee(model).save().then(employee => {
employee.token = auth.getToken(employee);
return employee.save();
}).then(employee => {
return res.data(mapper.toFullModel(employee));
});
}).catch(err => {
res.failure(err);
});
