fastify-frontend-logger

A Fastify plugin for receiving browser logs to a server

Features

• Very customizable
• Logger objects like pino
• Appends "type": "frontend-logger" to every log.

Quickstart

yarn add fastify-frontend-logger

import fastify from 'fastify';
import { frontendLoggerPlugin } from 'fastify-frontend-logger';

const server = fastify();
server.register(frontendLoggerPlugin);

The frontend logger adds a method to your server at /logger. This consumes a default logger object:

[
  {
    "msg": "Hello world",
    "level": 30,
    "time": 1483531681798,
    "ctx": {
      "browser": "Firefox"
    },
    "payload": {
      "users": ["cobraz"]
    }
  }
]

Note: You can change how the logger object is by setting bodySchema in the plugin options.

Options

• path can be used to change where the logger is served (defaults to /logger).
• bodySchema can be used to change the validation schema.
• preHandler can be used to run code before passing to logs (e.g. authentication)
• loggerOptions the plugin adds a logger child, with this option you can set your own.
