Nodejs - Async/Await to my controller - node.js

Question

Right now i have this route controller
export let remove = (req: Request, res: Response) => {
Area.removeAndRecalc(req.query.ids).then(() => {
return res.json({ success: true });
});
};
and calls the following model method
areaSchema.statics.removeAndRecalc = async function(ids) {
let parents = await this.model("Area").find({_id: ids});
await this.model("Area").delete(
{
_id: ids
}
);
await parents.forEach((parent) => {
parent.recalcParentChilds();
})
return;
}
The function returns a promise. Is it possible to write this code inside the controller? I try to use "async" to my controller but i doesn't work
Something like this (doesn't work)
export let remove = async (req: Request, res: Response) => {
let parents = await this.model("Area").find({_id: req.query.ids});
await this.model("Area").delete(
{
_id: req.query.ids
}
);
await parents.forEach((parent) => {
parent.recalcParentChilds();
})
return res.json({ success: true });
};

It's not clear "what" exactly doesn't work. An exception or description of the bad behaviour would be useful.
But check out async-middleware. I'm using it like this, for example in some projects:
import { wrap } from 'async-middleware'
//Loads of code, some of which creates router, an Express router.
router.get('/some/path/here', wrap(async (req, res) {
var data = await dataFromService();
res.write(renderData(data));
res.end();
}));
//Loads of code

I think there is a mistake with forEach in the remove function , forEach returns undefined not a promise so await won't work as expected, try to something like this :
export let remove = async (req: Request, res: Response) => {
//...
for (let i=0; i< parent.length;i++){ // <-- use for loop instead of forEach
await parent.recalcParentChilds();
}
return res.json({ success: true });
};
