Mongodb: Fetch

Find all

const {MongoClient, ObjectId} = require('mongodb');

const URL = 'mongodb://localhost:27017/<my_app>';

MongoClient.connect(URL, (err, db) => {

if (err) {
return console.log('Unable to connect to mongo db.', err);
}

console.log('Connected to mongo db.');

db.collection('<my_table>').find().toArray().then((docs) => {
console.log(JSON.stringify(todos, undefined, 2));

}, (err) => {
console.log('unable to fetch todos', err);
});
});

Perform search

const {MongoClient, ObjectId} = require('mongodb');

const URL = 'mongodb://localhost:27017/<my_app>';

MongoClient.connect(URL, (err, db) => {

if (err) {
return console.log('Unable to connect to mongo db.', err);
}

console.log('Connected to mongo db.');

db.collection('<my_table>').find({
   // Object search criteria as an object    // {
   // attribute1: atribute1Value,
   // ...
   // attributeN: atributeNValue
   // }
}).toArray().then((docs) => {
console.log(JSON.stringify(todos, undefined, 2));

}, (err) => {
console.log('unable to fetch todos', err);
});
});

Search by id

const {MongoClient, ObjectId} = require('mongodb');

...

db.collection('<my_table>').find({
   // Object search criteria as an object    // {
   // _id: new ObjectID(<objects_id>)
   // }
}).toArray().then((docs) => {
console.log(JSON.stringify(todos, undefined, 2));

}, (err) => {
console.log('unable to fetch todos', err);
});

});
