I'm doing a database query in an async
function, then calling it from another file with a promise
. But the result of the promise
is always undefined
.
My db function:
async function findSomething(id) {
var query = "my_query";
connection.query(query);
};
This is how I'm calling it from another file:
DbUtil.findSomething(1).then(function(result, error) {
if(!error) {
console.log("the result " + result);
}
});
The result is always undefined
.
Note that the calling function, DbUtil.findSomething
is called from another file. I do not want to chain it inside the findSomething()
function.
What am I missing?
You are missing a return
statement.
Any function without one returns undefined
.
Since findSomething
is as async
function, the return value is used to resolve the promise it returns.
async function findSomething(id) {
var query = "my_query";
return connection.query(query);
};
