JavaScript SDK for data deployment

By acckiygerman, anuveyatsu

Here we explain how you can use JavaScript SDK for data deployment purposes. If you need a detailed step-by-step tutorial, please, go to this article:

https://datahub.io/docs/tutorials/js-sdk-tutorial

Prerequisites

  1. You need to have NodeJS (>= 7.6) and NPM.

  2. Installed datahub-client and data.js NPM packages:

    npm install datahub-client data.js --save

Example of usage

Following code snippet is a working example for basic usage. It uses credentials stored in ~/.config/datahub/config.json, which is created when you login using the CLI tool.

const {DataHub, config, authenticate} = require('datahub-client') const {Dataset} = require('data.js')  async function pushDataset(datasetPath) {  // First, authenticate user  const apiUrl = config.get('api')  const token = config.get('token')  const response = await authenticate(apiUrl, token)  if (!response.authenticated) {  console.error('Your credentials expired or missing.')  return  }  // Load dataset that we want to push  const dataset = await Dataset.load(datasetPath)  // Create an instance of the DataHub class, using the data from the user config  const configs = {  apiUrl,  token,  ownerid: config.get('profile') ? config.get('profile').id : config.get('id')  }  const datahub = new DataHub(configs)   // Now use the datahub instance to push the data  const res = await datahub.push(dataset, {findability: 'unlisted'})  console.log(res) }  pushDataset('path/to/dataset') 

This is an example of correct console output:

{ dataset_id: 'username/finance-vix',  errors: [],  flow_id: 'username/finance-vix/1',  success: true } 

That is all needed to get your dataset deployed in DataHub!
