Question 1

Should I use electron-store or a real database for my Electron app?

Accepted Answer

Use electron-store for small, simple data like user settings or app state, as it's lightweight and easy. For larger datasets or complex queries, opt for SQLite or a database, since electron-store reads/writes the entire file on each change, slowing down with more data.

Question 2

How do I encrypt my electron-store configuration file?

Accepted Answer

Set the encryptionKey option with a string or buffer when creating a Store instance, and choose an encryptionAlgorithm like aes-256-gcm for authentication. Note that this is for obscurity, not security, as the key is in plain text within the app.

Question 3

Can electron-store handle storing large amounts of data efficiently?

Accepted Answer

No, it's not designed for large data. The README states it reads and writes the entire JSON file on every change, so performance degrades with data over 1 MB. Use SQLite or save files to disk for larger datasets.

Question 4

How can I use electron-store in both the main and renderer processes?

Accepted Answer

Call Store.initRenderer() in the main process or create a Store instance there, then import and use it in the renderer. This sets up IPC channels automatically, allowing shared data access without manual message passing.

Question 5

What are the common pitfalls with electron-store migrations?

Accepted Answer

Migrations have known bugs and lack maintainer support, so errors during version upgrades might corrupt data. Always backup config files and test migrations thoroughly, as the feature is marked as unsupported in the docs.
