How to get full list of users with Mongoose and JavaScript?
To get full list of users with Mongoose and JavaScript, we can use the forEach method.
For instance, we write
server.get("/usersList", (req, res) => {
User.find({}, (err, users) => {
const userMap = {};
users.forEach((user) => {
userMap[user._id] = user;
});
res.send(userMap);
});
});
to create the /usersList Express route.
In it, we call User.find with an empty object to get all users.
We get the users from the callback with the users parameter.
We call users.forEach to loop through each entry and put them in the userMap object.
user._id has the unique ID for each entry.
