Hi

I don't think we have any immediate plans to include this in the docs, the
idea about using cURL is that it's completely language neutral and any
language these days should give you the tools to interact with the API.

That said, a simple example for fetch the data elements from a DHIS2 server
would be (you need node-fetch installed):

const fetch = require( "node-fetch" );

const createAuthenticationHeader = (username, password) => {
  return "Basic " + new Buffer( username + ":" + password ).toString(
"base64" );
};

fetch( '
https://play.dhis2.org/dev/api/dataElements?paging=false&filter=domainType:eq:TRACKER',
{
  headers: {
    "Accept": "application/json",
    "Authorization": createAuthenticationHeader( 'admin', 'district' )
  }
} )
  .catch( err => console.error( err ) )
  .then( res => res.json() )
  .then( res => {
    console.log( res.dataElements.length );
  } )
  .catch( err => console.error( err ) );

If you would want to use an OAuth2 bearer token instead you would change
the Authorization header.
