A quick overview of a sample .NET Core server

We have prepared a sample .NET Core server that implements the Flexmonster custom data source API. It is available at the server-dotnetcore/ folder on the api-data-source GitHub repository.

All requests from Flexmonster Pivot Table are handled by http://localhost:3400/api/cube endpoints. Raw data is stored in JSON format in the data/ folder. The file name matches the index property of the dataSource configuration object.

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

git clone https://github.com/flexmonster/api-data-source my-proj
cd my-proj

To start the server, run the following commands in a console:

cd server-dotnetcore
dotnet restore
dotnet run

On the client side (see client/index.html), the report is configured as follows:

new Flexmonster({
container: "#pivot",
report: {
dataSource: {
type: "api",
url: "http://localhost:3400/api/cube",
index: "fm-product-sales"

By default, the server uses the data stored in JSON format. This option can be configured in appsettings.json:

"DataSource": {
    "DataSourceName": "json"

If you want to use CSV, you need to change it like this:

"DataSource": {
    "DataSourceName": "csv"

To use a database you must add the type of a database (MySQL, MSSQL, and PostgreSQL are supported), add the connection string and a query to retrieve data. The DatabaseType property must be one of the following: mysql, mssql or postgresql. On the client side, index in the configuration must be one from Indexes property. It will execute the query you specified.

"DataSource": {
"DataSourceName": "database",
    "DatabaseType": "mysql",
    "ConnectionStrings": {
    "DefaultConnection": "CONNECTION_STRING"
    "Indexes": {

Note that the server can work only with one data source at the same time.
