first off I'd like to make clear that I'm new to node.js and this may sound like a silly question but, how am I supposed to return data out of model.find() function in mongoose ( eg. with a var.exports = var )?<
const data = () =>
{
MyModel.find().then(function(result){
console.log(result);
return(result);
});
}
exports.data = dataBeing the query asyncronous I'm not able to retrieve these data until the function is completed (so never). Is there anyway to return these informations in a variable eg:
const retriever = require('../utils/test.js') //calling the exports file
test = retriever.data
console.log(test)Thank you very much in advance
With promises you can achieve it as follows
const data = () => {
return MyModel.find({});
}
// using it in another function
const result = await data();
1.You can use a callback, as below
const data = (callback) =>
{
MyModel.find().then(function(result){
console.log(result);
//return(result);
callback(results);//we pass in a function which will be used to pull out
//data
});
}
exports.data = data
// THE AREA WHERE THIS CODE IS USED
const {data} = require('./to/data')
//show data
data(function (result) {
console.log( result );// data from callback
})
2. using async/await promies
const data = async () =>
{
let results = await MyModel.find();
}
exports.data = data
ON USING THIS FUNCTION
const {data} = require('./to/data')
(async function () {
let res = await data();
console.log(res);
})()
