Getting started with the MongoDB Connector

For easy and comfortable connection to MongoDB, Flexmonster suggests you using a special connector based on the custom data source API. 

The Connector has to be embedded into a middle-layer server that accepts requests from Flexmonster and passes them to the Connector. The Connector then fetches the needed data and sends it back to the server, and then the data goes to Flexmonster and gets displayed in your browser.

For you to have a better understanding of how the Connector, the server, and Flexmonster cooperate, we prepared a sample ready-to-use project.  Proceeding from this project, you can also connect to your MongoDB database.


To run a simple application you will need Node.js and npm. Get it here if it’s not already installed on your machine.

Run a sample GitHub project

To run our sample project from GitHub, follow these steps:

Step 1. Download the .zip archive with the sample or clone it from GitHub with the following command:

git clone my-proj
cd my-proj

Step 2. Install the npm packages described in package.json:

npm install

Step 3. Open the client/index.html file and add your license or trial key. If you don’t have a license key, get a trial key here.

var pivot = new Flexmonster({
   container: "#pivot",
componentFolder: "",
   height: 600,
   toolbar: true,
   report: {
    "dataSource": {
        "type": "api",
           "url": "http://localhost:9204/mongo",
           "index": "fm-product-sales"

Step 4. Run the server with the following commands:

npm run build
npm run start

Now, when the server is running and ready to accept Flexmonster’s requests, you can open client/index.html in the browser to see the Connector’s output.

Note that in this tutorial you connect to the Flexmonster’s sample database. To get the data from your database, follow the steps from the section below.

Connect to your MongoDB database

You can also use the sample project to connect to your MongoDB database. To accomplish this, complete the following steps:

Step 1. Open src/controller/mongo.ts and replace the present connection string with yours:

MongoClient.connect("your connection string", {

Step 2. Then replace the database name with the needed one:

dbo = db.db("your database name");

Step 3. In client/index.html, replace the index’s value with your collection’s name:

report: {
"dataSource": {
    "type": "api",
    "url": "http://localhost:9204/mongo",
    "index": "your-collection-name"

Step 3. Run the server with the following commands:

npm run build
npm run start

Now the data from your MongoDB database can be seen when opening the client/index.html file in a browser.

You can take our sample project as a ready template and make it work the way you need by adding your logic, improving and expanding the project.

If you are interested in embedding the Connector into your server, refer to this tutorial:
