@polkadot/extension-base
Functions, classes and other utilities used in @polkadot/extension. These include:
- background script handlers,
- message passing,
- scripts injected inside pages.
They are primarily meant to be used in @polkadot/extension, and can be broken without any notice to cater for @polkadot/extension's needs.
They are exported here if you wish to use part of them in the development of your own extension. Don't forget to add process.env.EXTENSION_PREFIX to separate ports and stores from the current extension's ones.
