Node.js MongoDB Find

✅ Node.js MongoDB – Find Documents

MongoDB provides methods to retrieve data from a collection:

findOne() → returns one document
find() → returns multiple documents (cursor)

⭐ 1. Find One Document – `findOne()`

Example

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";
const client = new MongoClient(url);

async function run() {
try {
await client.connect();

const db = client.db("mydb");
const collection = db.collection("customers");

// Find one
const result = await collection.findOne({ name: "John" });

console.log(result);
} finally {
await client.close();
}
}

run();

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";

const client = new MongoClient(url);

async function run() {

try {

await client.connect();

const db = client.db("mydb");

const collection = db.collection("customers");

// Find one

const result = await collection.findOne({ name: "John" });

console.log(result);

} finally {

await client.close();

}

run();

⭐ 2. Find All Documents – `find()`

Example

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";
const client = new MongoClient(url);

async function run() {
try {
await client.connect();

const db = client.db("mydb");
const collection = db.collection("customers");

const cursor = collection.find(); // No filter → returns all

const results = await cursor.toArray();

console.log(results);
} finally {
await client.close();
}
}

run();

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";

const client = new MongoClient(url);

async function run() {

try {

await client.connect();

const db = client.db("mydb");

const collection = db.collection("customers");

const cursor = collection.find(); // No filter → returns all

const results = await cursor.toArray();

console.log(results);

} finally {

await client.close();

}

run();

⭐ 3. Find With Condition (WHERE query)

Example

⭐ 4. Find With Multiple Conditions

Example

⭐ 5. Find With Comparison Operators

MongoDB Operator	Meaning
`$gt`	greater than
`$lt`	less than
`$gte`	greater than or equal
`$lte`	less than or equal
`$ne`	not equal
`$in`	in array

Example

⭐ 6. Find With Sorting + Limit

`sort()`	Sort results
`limit()`	Limit the number of results
`toArray()`	Convert cursor to array
