Description:

angel3 file service

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')
),
);
}
