Storing user data / Cache data

There is a few options to save user data depending on the use case

User independant User specific
Global GlobalStorage UserSpecificDataStore
Local(Per window) localStorage localStorage

Global storage

For saving large set of data. Prefer one of the DataStore for smaller ones

This this the lowsest level data storage. It will support synchronzing the content of a key across the app. It is implemented differently depending on the environment:

  • Electron main: Save to $(userdata)/data/ folder
  • Electron renderer: Calls to the Electron main service
  • Browser only: User localStorage

Use when:

  • To implement a higher level store
  • Having to save large set of data

Do not use for:

  • Caching data
  • If the data should not be shared between windows(Each process should have its local version)
  • Small values

UserSpecificDataStore

When having to save user specific data/state(No for caching)

Use when:

  • The data saved should not be shared between users

Do not sure for:

  • If the data is not user specific
  • If the data should not be shared between windows(Each process should have its local version)
