This is my code for deleting object containg name as 'bob':
app.delete('/user/:id', async (req, res) => {
const id = req.params.id;
const query = { name: "bob" }
const result = await userCollection.deleteOne(query);
res.send(result);
});
This code delete all objects that have name as 'bob', but I want to delete any one instance only from db matching this query, not all objects. And is there any way to set count that how many instance I want to delete matching this query?
You can use this code
const ObjectId = require("mongodb").ObjectId;
app.delete('/user/:id', async (req, res) => {
const id = req.params.id;
const query = { _id: ObjectId(id) };
const result = await userCollection.deleteOne(query);
res.send(result);
});
