logkitty

What is logkitty?

Logkitty is a tool for reading Android logcat logs. It provides a simple and efficient way to filter and display log messages from Android devices, making it easier to debug and monitor applications.

What are logkitty's main functionalities?

Basic Logcat Reading

This feature allows you to start reading logcat logs from an Android device. The code sets up a logkitty reader and starts it, printing each log entry to the console.

const { logkitty, android } = require('logkitty');
const reader = logkitty();
reader.on('entry', entry => console.log(entry));
reader.start();

Filtering Logs

This feature allows you to filter logcat logs by specific tags. The code sets up a logkitty reader with a filter to only show logs tagged with 'MyApp'.

const { logkitty, android } = require('logkitty');
const reader = logkitty({ filter: [android.filters.byTag('MyApp')] });
reader.on('entry', entry => console.log(entry));
reader.start();

Custom Log Entry Formatting

This feature allows you to customize the format of log entries. The code sets up a logkitty reader and formats each log entry to display the tag and message.

const { logkitty, android } = require('logkitty');
const reader = logkitty();
reader.on('entry', entry => console.log(`${entry.tag}: ${entry.message}`));
reader.start();
