NGSI v2 Javascript and NodeJS SDK

This SDK is automatically generated by the Swagger Codegen project:

  • API version: v2 RC-2018.04 (available here)
  • Package version: 0.2.0
  • Build package: io.swagger.codegen.languages.JavascriptClientCodegen


For Node.js


The library is available at npmjs.

To install it via npmjs:

npm install ngsi_v2 --save
Local development

To use the library locally without publishing to a remote npm registry, first install the dependencies by changing into the directory containing package.json (and this README). Let's call this JAVASCRIPT_CLIENT_DIR. Then run:

npm install

Next, link it globally in npm with the following, also from JAVASCRIPT_CLIENT_DIR:

npm link

Finally, switch to the directory you want to use your ngsi_v2 from, and run:

npm link /path/to/<JAVASCRIPT_CLIENT_DIR>

You should now be able to require('ngsi_v2') in javascript files from the directory you ran the last command above from.


If you fork and customise the library, in a git repository, e.g. then install it via:

    npm install --save

For browser

The library also works in the browser environment via npm and browserify. The latest compiled version of the javascript library is available at

To embed it in your HTML code:

<script src=""></script>

In case of changes to the code, after following the above steps with Node.js and installing browserify with npm install -g browserify, perform the following:

browserify js/main.js --require superagent --exports require -o js/ngsi.js

Then include ngsi.js in the HTML pages.

Webpack Configuration

Using Webpack you may encounter the following error: "Module not found: Error: Cannot resolve module", most certainly you should disable AMD loader. Add/merge the following section to your webpack config:

module: {
  rules: [
      parser: {
        amd: false

Getting Started

Please follow the installation instruction and execute the following JS code:

var NgsiV2 = require('ngsi_v2');
var defaultClient = NgsiV2.ApiClient.instance;
// Configure API key authorization: fiware_token
var fiware_token = defaultClient.authentications['fiware_token'];
fiware_token.apiKey = "YOUR API KEY"
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//fiware_token.apiKeyPrefix['X-Auth-Token'] = "Token"
var api = new NgsiV2.APIEntryPointApi()
var callback = function(error, data, response) {
  if (error) {
  } else {
    console.log('API called successfully. Returned data: ' + data);
