## Features
### Minimal Setup
Just include the Errsole package in your code—no need for dedicated servers, software installations, or complicated configurations.
### Logger++
Errsole automatically collects all logs from the Node.js console. Additionally, it provides advanced logging functions that support multiple log levels and the ability to attach metadata to logs. [Read More](https://github.com/errsole/errsole.js/blob/master/docs/advanced-logging-functions.md)
### Store Anywhere
Store your logs wherever you want—whether in a file or any database of your choice. You can also configure log rotation to specify how long logs should be retained.
### Log Viewer
View, filter, and search through your logs using the built-in Web Dashboard. Secure authentication and team management features ensure that only you and your team can access the logs.
### Critical Error Notifications
Get immediate notifications when your app crashes or encounters critical errors. The notification includes the error message, the app name, the environment, the server name, and a direct link to view the error in your logs.
## Benchmarks
A Node.js app using Errsole Logger can handle 90,000 more requests per minute than when using Elasticsearch and 70,000 more requests per minute than when using Amazon CloudWatch. [Read More](https://github.com/errsole/errsole.js/blob/master/docs/benchmarks.md)
## Setup
#### Development Environment
For local development or scenarios where you prefer storing logs directly on the server, you can integrate Errsole with SQLite. When using SQLite, logs will be stored in a file on your server.
