Chronos-logger

A smart logger that buffers the logs/data and posts/flushes it to a set destination periodically. Aggregates the logs and sends/writes them in a batch.

Dependency

• Absolutely none

Installation

`npm install chronos-logger`

Usage

var chronos = require("chronos-logger");
var logger = chronos.logger(options);
logger.log({type:"info", time:"124684168","log this"});
logger.log({type:"error", time:"124684168","log this"});
console.log(logger.size()); // 128 bytes
console.log(logger.flush()); // manually flush the logs
console.log(logger.clear()); // clear all the buffered logs 

Options

"options" is a JSON containing some or all of the following properties:

1. isJson - true if the logs have to be treated as JSON and sent as an array of JSON, false just treats logs as an array of strings
2. encoding - available encoding are: a.UTF-8 b.ASCII (fastest) c.UTF16LE d.UCS2 e.base64 f.binary f. hex
3. useFile - false: use a buffer only , true: data is written to a specified file
4. maxBufferSize - Maximum size of buffer to be maintained in bytes
5. maxLogsInBuffer - max logs to be maintained
6. minLogsInBuffer - min logs to be present in buffer if it is to be flushed
7. postOptions - typical http options required when posting data to the server, refer
8. flushInterval - interval between two successive flushing of logs in buffer

Advantages:

1. Total control over logging behavior - custom flush intervals, batch size (via maxBufferSize)
2. Completely ASYNC

Notes

1. Uses a singleton logger approach, only one logger is available to take care of your logging needs
2. Buffer will be written/posted only when: (1) Buffer is full (2) maxLogsInBuffer has reached its limit

To Do:

    File output
    Error handling
    Gzip outgoing requests
    Custome flushing/logging strategy
