Angel service that persists data to a file on disk, stored as a JSON list.

File Service for Angel3

Angel service that persists data to a file on disk, stored as a JSON list. It uses a simple mutex to prevent race conditions, and caches contents in memory until changes are made.

The file will be created on read/write, if it does not already exist.

This package is useful in development, as it prevents you from having to install an external database to run your server.

When running a multi-threaded server, there is no guarantee that file operations will be mutually excluded. Thus, try to only use this one a single-threaded server if possible, or one with very low load.

While not necessarily slow, this package makes no promises about performance.

Usage

configureServer(Angel app) async {
  // Just like a normal service
  app.use(
    '/api/todos',
    JsonFileService(
      const LocalFileSystem().file('todos_db.json')
    ),
  );
}
