SlicingDice Official JavaScript Client (v2.0.2)

Official JavaScript client for SlicingDice - Data Warehouse and Analytics Database as a Service.

SlicingDice is a serverless, SQL & API-based, easy-to-use and really cost-effective alternative to Amazon Redshift and Google BigQuery.

Build Status: CircleCI

Code Quality: Codacy Badge

Documentation

If you are new to SlicingDice, check our quickstart guide and learn to use it in 15 minutes.

Please refer to the SlicingDice official documentation for more information on how to create a database, how to insert data, how to make queries, how to create columns, SlicingDice restrictions and API details.

Tests and Examples

Whether you want to test the client installation or simply check more examples on how the client works, take a look at tests and examples directory.

Installing

In order to install the JavaScript client, you only need to use npm.

npm install slicerjs

Usage

The following code snippet is an example of how to add and query data using the SlicingDice javascript client. We entry data informing user1@slicingdice.com has age 22 and then query the database for the number of users with age between 20 and 40 years old. If this is the first register ever entered into the system, the answer should be 1.

var SlicingDice = require('slicerjs'); // only required for Node.js
 
// Configure the client
const client = new SlicingDice({
  masterKey: 'MASTER_API_KEY',
  writeKey: 'WRITE_API_KEY',
  readKey: 'READ_API_KEY'
});
 
// Inserting data
const insertData = {
    "user1@slicingdice.com": {
        "age": 22
    },
    "auto-create": ["dimension", "column"]
};
client.insert(insertData);
 
// Querying data
const queryData = {
    "query-name": "users-between-20-and-40",
    "query": [
        {
            "age": {
                "range": [
                    20,
                    40
                ]
            }
        }
    ]
};
client.countEntity(queryData).then((resp) => {
    console.log(resp);
}, (err) => {
    console.err(err);
});

Reference

SlicingDice encapsulates logic for sending requests to the API. Its methods are thin layers around the API endpoints, so their parameters and return values are JSON-like Object objects with the same syntax as the API endpoints

Constructor
