Getting Started

Install

npm install --save powerbi-models

Import

import * as models from 'powerbi-models';

Usage

Validation:

let testObject = { x: 1 };

const errors = models.validateLoad(testObject);

if(errors) {
  console.warn(errors);
}

Would output to the console:

[
  {
    message: 'accessToken is required'
  }
]

Creating filters:

const basicFilter: models.IBasicFilter = {
  target: {
    table: "Products",
    column: "Version"
  },
  operator: "In",
  values: [
    1,
    2,
    3,
    4
  ]
};

const advancedFilter: models.IAdvancedFilter = {
  target: {
    table: "Products",
    column: "Name"
  },
  logicalOperator: "Or",
  conditions: [
    {
      operator: "Contains",
      value: "Power"
    },
    {
      operator: "Contains",
      value: "Microsoft"
    }
  ]
};

Or use the constructor methods:

const advancedFilter = new models.AdvancedFilter(
  {
    table: "Products",
    column: "Name"
  },
  "Or",
  {
    operator: "Contains",
    value: "Power"
  },
  {
    operator: "Contains",
    value: "Microsoft"
  }
);

Date Formatting

Dates should be formated using ISO 8601 standard. Example: 2016-09-08T00:15:46.861Z

This is how dates are naturally serialized to JSON:

new Date().toJSON(); //=> 2016-09-08T00:15:46.861Z

An example filter using this Date format would look like the following:

{
  "$schema": "http://powerbi.com/product/schema#advanced",
  "target": {
    "table": "Time",
    "column": "Date"
  },
  "logicalOperator": "And",
  "conditions": [
    {
      "operator": "GreaterThan",
      "value": "2014-06-01T07:00:00.000Z"
    }
  ]
}
