Cordova-sqlite-storage's plugin can't be added

Hello, I need to add the Cordova-sqlite-storage’s plugin to provide a database based on SQLite in my new project.
I installed it with this command :
ionic start SWMG blank -app-name="NewProject"
Secondly I tryed to add the plugin several times by typing this… I received each time the same error :

cordova plugin add cordova-sqlite-storage --save

Error: Failed to fetch plugin cordova-sqlite-storage@2.0.4 via registry.
Probably this is either a connection problem, or plugin spec is incorrect
.
Check your connection and plugin name/version/URL.

[ERROR] An error occurred while running cordova plugin add
cordova-sqlite-storage@2.0.4 --save (exit code 1).

So I try with this command it’s the same bad message :
cordova plugin add cordova-sqlite-storage@2.0.4 --save

I don’t understand because all any plugin adding works.
Moreover in this log I find the repository where is downloaded the plugin files :
https://registry.npmjs.org/cordova-sqlite-storage
…When it’s opened in a browser the repository don’t seem to be offline !
Thank you to help.

try ionic cordova plugin add cordova-sqlite-storage

According to your post, you were missing ionic in the command. And hold off on --save until
npm install --save @ionic-native/sqlite

It works perfectly. Thank you for you promptness.
I didn’t find the documentation of this plugin. Thank you really for your time !

Hello,

documentation is here.
