Build MongoDB-Connected Web Apps in Servoy

Use Servoy Developer to easily connect to MongoDB data and build web apps with connectivity to live MongoDB data.

Servoy is a rapid application development and deployment platform. When paired with the CData JDBC Driver for MongoDB, users can build MongoDB-connected apps that work with live MongoDB data. This article describes how to connect to MongoDB from Servoy and build a simple web app to display and search MongoDB data.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live MongoDB data. When you issue complex SQL queries to MongoDB, the driver pushes supported SQL operations, like filters and aggregations, directly to MongoDB and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying lets you work with MongoDB data using native data types.

Connect to MongoDB in Servoy Developer

To build MongoDB-connected apps, you need to first create a data provider in Servoy Developer using the CData JDBC Driver for MongoDB.

  1. Install the JDBC Driver.
  2. Copy the JDBC Driver JAR file. (cdata.jdbc.mongodb.jar) to the /application_server/drivers/ directory in the installation directory for Servoy.
  3. Open Servoy Developer.
  4. In the Solution Explorer, right-click Database Server (under Resources) and choose "Connect to existing database" -> "empty."
    1. Name the server.
    2. Click to show the advanced server settings.
      • Set the URL, for example: jdbc:mongodb:Server=MyServer;Port=27017;Database=test;User=test;Password=Password;

        Built-In Connection String Designer

        For assistance in constructing the JDBC URL, use the connection string designer built into the MongoDB JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

        java -jar cdata.jdbc.mongodb.jar

        Fill in the connection properties and copy the connection string to the clipboard.

        Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

      • Select the Driver class you just copied, for example, cdata.jdbc.mongodb.MongoDBDriver

Build a MongoDB-Connected Web App

Once you have configured the connection to MongoDB in the Servoy Developer resources, you are ready to build apps with access to live MongoDB data.

Create a New Solution

  1. In the Server Explorer, right-click "All solutions" and select "Create new solution."
  2. Name the solution.
  3. Select the checkbox to include the "search" module.
  4. Click "Finish."

Create a New Form

Right-click "Forms" and select "Create new form."

  1. Name the form.
  2. Select a Datasource.
  3. Set the type (e.g., Simple) and click "Finish."

Add a Data Grid to the Form

  1. Drag a Data Grid component (from Servoy NG-Grids) onto the form.
  2. Drag a column component onto the Data Grid and set the "dataprovider" property for each column component to a column from the MongoDB "table" (e.g., borough from the restaurants table).

    Continue adding columns as desired.

Add Searching to the App

Note that the "svySearch" extension is required to add search functionality (included by default when you create a new solution). If you did not add the extension when you created the solution or you are modifying an existing solution, you can add the search module by right-clicking Modules (in the solution) and selecting "Add Module." Select "svySearch" and click "OK."

  1. Drag a Text Field component onto the Form.
  2. Right-click the Form and select "Open in Script Editor."
  3. Create a new variable (JavaScript) to hold the search value:
    var searchText = '';
    
  4. Back on the Form, in the Text Field properties:
    1. Set the "dataprovider" property to the Form variable you just created.
    2. Double-click to add a method for the onAction event.
    3. Click to create the method in "Form," name the method (e.g., onEnter), and click "Create private."
    4. Click "OK & Show."
  5. Add the following JavaScript to the JavaScript file to use the Servoy framework to implement searching bound data based on the text in the Text Field:
    var search = scopes.svySearch.createSimpleSearch(foundset).setSearchText(searchText);
    search.setSearchAllColumns();
    search.loadRecords(foundset);
    

Save and Launch the App

Save the form and JavaScript file, then click Run -> Launch NGClient to start the web app.
