You can add async at the beginning of your function.
async function example() {
const response = await doSomethingAsync();
console.log(response);
}

moongoose js Schema is not a Constructor and function error

I am facing a problem with moongoose js
This is my node js code:
var mongoose=require('moongoose');
var test=mongoose.Schema({test:String})
module.exports = mongoose.model('test',test);
When I run this code, node js throws:
var test=mongoose.Schema({test:String})
^

If I change this code to this format:
var mongoose=require('moongoose');
var Schema = mongoose.Schema;
var test=new Schema({test:String})
module.exports = mongoose.model('test',test);
That code throws:
TypeError: **Schema is not a constructor**
Please help me to resolve this code error.

Its require('mongoose'); you have written require('moongoose');
an o typo :))

collection = db.get('mycollection'),
transactions = wrap(collection);
var app = koa();
app.use(function*(){
var res = yield transactions.find({});
console.log(res);
});
app.listen(3000);
