Usage

Single script injection

  import 'injectScript' from 'inject-scripts';

  injectScript("https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js").then(() => {
    console.log ( "🤟Yay ! script injected" );
  });

                -------- or  --------

  let singleScript = {
    id: 'datefns',
    src: 'https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js',
    attributes: [
      {
        name: 'data-library',
        value: 'datefns'
      }
    ]
  };

  injectScript(singleScript).then(() => {
    console.log ( "🤟Yay ! script injected" );
  });

  ---->
  <script type="text/javascript" id="datefns" data-test-script="datefns" data-library="datefns"
  src="https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js"></script>

Multiple scripts injection

  import 'injectScripts' from 'inject-scripts';

  let multipleScripts = [
    {
      id: 'datefns',
      src: 'https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js',
      attributes: [
        {
          name: 'data-library',
          value: 'datefns'
        }
      ],
      once: true
    },
    {
      id: 'inline',
      inline: `console.log('inline script rendered')`,
      attributes: [
        {
          name: 'data-inline',
          value: 'true'
        }
      ]
    }
  ]

  injectScripts(multipleScripts).then((events) => {
    // events - holds data for all scripts injection as array
    console.log ( "🤟🤟🤟Yay ! multiple scripts injected" );
  });

  ---->
  <script type="text/javascript" id="datefns" data-test-script="datefns" data-library="datefns"
  src="https://cdnjs.cloudflare.com/ajax/libs/date-fns/1.30.1/date_fns.js"></script>

  <script type="text/javascript" id="inline" data-test-script="inline" data-inline="true">
    console.log('inline script rendered');
  </script>

injectScripts function expects object for single script inject and array of objects for multiple scripts injection as parameter, the object items are,

name	type	description
id	string : optional	Adds an id attribute to the script element id=id and also creates a test selector data-test-script=id
type	string : optional : default text/javascript	Adds type to the script element
src	string : optional	Adds a source to the script element src=src
inline	string : optional	Adds inline contents to the script element <script> inline </script>
once	boolean : optional	Looks for an element with the same id passed. If founded avoids the injection and returns the dom element as target
attributes	Array of objects : optional { name: 'data-inline', value: 'true' }	Adds attribute contents to the script element <script data-inline="true"> inline </script>
onload	function : optional	Callback function for successive load of script. not available for inline scripts
onerror	function : optional	Callback function for failure while loading of script. not available for inline scripts

injectScripts.then() will return all the cacheable event values as array for all passed script elements.

inline scripts will have only target as the event value.
