Connecting to a MySQL database using Flexmonster Data Server

This tutorial describes how to connect to a MySQL database using Flexmonster Data Server – a special server developed by Flexmonster. This server communicates with the client using the custom data source API – our custom communication protocol allowing you to retrieve already aggregated data from a server to Flexmonster Pivot.

Prerequisites

To download the Data Server, you will need Flexmonster CLI — a command-line interface tool for Flexmonster. If needed, install the CLI globally using npm:

npm install -g flexmonster-cli

After that, a new flexmonster command will be available in the console. Learn more about Flexmonster CLI and its commands in our documentation.

Now follow the steps below to connect to MySQL using the Data Server.

Step 1. Embed the component into your web page

If Flexmonster is not yet embedded, set up an empty component in your web page:

In pure JavaScript

Complete the Quick start guide. Your code should look similar to the following example:

var pivot = new Flexmonster({
    container: "pivotContainer",
    toolbar: true
});

In Angular

Complete the Integration with Angular guide. Your code should look similar to the following example:

<fm-pivot 
[toolbar]="true">
</fm-pivot>

In React

Complete the Integration with React guide. Your code should look similar to the following example:

<FlexmonsterReact.Pivot
toolbar={true}
/>

In Vue

Complete the Integration with Vue guide. Your code should look similar to the following example:

<Pivot
ref="pivot"
toolbar>
</Pivot>

Step 2. Download Flexmonster Data Server

The previous step demonstrated how to configure Flexmonster Pivot. Now it’s time to set up Flexmonster Data Server.

Get the Data Server with the following CLI command:

flexmonster add fds

The flexmonster add fds command will download the .zip archive with Flexmonster Data Server and automatically unpack the files in the current folder. As a result, the flexmonster-data-server/ folder will appear in your working directory.

The Data Server can be configured in the flexmonster-data-server/flexmonster-config.json file. To learn more about all the available configurations, see the configurations reference.

To set configurations needed for a MySQL database, follow the steps below.

Step 3. Configure the data source type

Set the "Type" property in flexmonster-config.json to "database". It should be done as follows:

"DataSources": [
    {
        "Type": "database"
    }
],

Step 4. Configure the database type

Specify the name of the database you want to use by adding the "DatabaseType" configuration to the flexmonster-config.json file. In this case, the configuration value should be "mysql":

"DataSources": [
{
      "Type": "database",
      "DatabaseType": "mysql"
  }
]

Step 5. Configure the connection with the database

To enable the server to fetch data from your database, you have to provide the connection string to the database. The connection string should be added to flexmonster-config.json as follows:

"DataSources": [
  {
      "Type": "database",
      "DatabaseType": "mysql",
      "ConnectionString":
"Server=localhost;Port=3306;Uid=root;Pwd=password;Database=database_name"
  }
]

Have a look at the examples of different connection strings for MySQL.

Step 6. Define the data subset

In the flexmonster-config.json file, create an index for the subset of data you want Flexmonster Pivot to visualize. "Query" is an SQL query for the data. For example:

"DataSources": [
  {
      "Type": "database",
      "DatabaseType": "mysql",
      "ConnectionString":
"Server=localhost;Port=3306;Uid=root;Pwd=password;Database=database_name",
      "Indexes": {
          "index_database": {
              "Query": "SELECT * FROM tablename"
          }
      }
  }
]

Note: "index_database" is a dataset identifier. It will be used to configure the data source on the client side.

In a similar way, additional indexes can be specified:

"Indexes": {
"index_database": {
  "Query": "SELECT * FROM tablename"
  },
   "another_index_database": {
       "Query": "SELECT column FROM tablename"
   }
}

Step 7. Run the server

To start the Data Server, run the following command in the console:

on Windows

flexmonster-data-server.exe

on macOS and Ubuntu/Linux

./flexmonster-data-server

As soon as you start Flexmonster Data Server, it automatically preloads the data specified in the "Indexes" property. Thus, when Flexmonster Pivot requests the data, the server responds with already preloaded data.

Note that the preloaded data is kept in the server’s RAM, so the number of indexes you can specify is limited by the amount of RAM available to the server.

Step 8. Configure the report

On the client side, the report should be configured as follows:

var pivot = new Flexmonster({
container: "pivotContainer",
toolbar: true,
report: {
dataSource: {
type: "api",
url: "http://localhost:9500",
index: "index-database"
}
}
});

Note 1: index must match the name of the index defined in step 5 (e.g., "index_database").

Note 2: when Flexmonster Pivot requests the data, Flexmonster Data Server server sends the response and then caches it. In case the component sends the same request once again, the server responds with the data from its cache. The cache is cleared only when the server is restarted, though the cache has a memory limit: when the limit is reached, and the new response can’t be cached, Flexmonster Data Server server deletes one of the previously cached responses from the cache.
