Install and use sparkline from composer

I don't see any docs on installing sparkline library for this module, so I'm using these drupal.org docs → .

That installs the library to web/libraries/jquery-sparkline rather than web/libraries/sparkline as the module expects.

So, I'm going to throw a patch here which adjusts for the library path.

An alternate solution which I'm happy to contribute to is that we document the correct procedure to install the sparkline dependency - let me know!

Steps (based on linked docs) below. This can probably be improved on to add a composer.json for this project so it automatically does the final step.

The recipe for setting up Asset Packagist for use in your projects is as follows:

1. Add the Composer Installers Extender PHP package by oomphinc to your project's root composer.json file, by running the following command:

   composer require oomphinc/composer-installers-extender

2. Add Asset Packagist to the "repositories" section of your project's root composer.json.

   "repositories": [
       {
           "type": "composer",
           "url": "https://asset-packagist.org"
       }
   ]

3. Ensure that NPM and Bower assets are registered as new "installer-types" and, in addition to type:drupal-library, they are registered in "installer-paths" to be installed into Drupal's /libraries folder, within the "extra" section of your project's root composer.json file.

   "extra": {
       "installer-types": [
           "npm-asset",
           "bower-asset"
       ],
       "installer-paths": {
           "web/libraries/{$name}": [
               "type:drupal-library",
               "type:npm-asset",
               "type:bower-asset"
           ]
       }
   }

4. The installation path of a specific library can be controlled by adding it to the "installer-paths" configuration above the general configuration. For example, the chosen module expects the library at /libraries/chosen, but composer require npm-asset/chosen-js installs the library into /libraries/chosen-js; the following override installs it into the expected folder:

   "extra": {
       "installer-paths": {
           "web/libraries/chosen": ["npm-asset/chosen-js"],
           "web/libraries/{$name}": [
               "type:drupal-library",
               "type:npm-asset",
               "type:bower-asset"
           ]
       }
   }
   

5. You may now require libraries from NPM or Bower via Composer on the command line:

   composer require npm-asset/jquery-sparkline

6. Contrib and custom modules may include these dependencies in their own respective composer.json files. See Requiring third-party libraries with Composer → for additional instructions.
