Importing the library into projects

API

Uses a name to value system.

Please note that each domain has its own unique set of name to value. It is a security feature inherited from indexedDB to ensure that there is no Cross-Origin Resource Sharing CORS.

For the followings,

"name" is a string.

"value" is any native JavaScript data types.

"callback_function" is optional.  It is a user provided function that it will be called upon the completion of the API commands.

Get a value by name

soStorage.get(name, callback_function);

Set a value by name

soStorage.set(name, value, callback_function);

Get a list of all available pairs (name to value)

soStorage.list(callback_function)

remove a value by name

soStorage.remove(name, callback_function);

clear all pairs (name to value)

soStorage.clear(callback_function);

  // do something with the "result"
