nodejs-lsd-logger v1.0.5

Node.js logger for LSD Server

Node.js logger for LSD streaming deamon

Logger writes to small files, depending on current time.

lsd_dir/category_name/year|month|day|hour|minute.log
// for example
lsd_dir/category_name/202302121626.log

All messages written to these files less than PIPE_BUF (4k in Linux by default).

If you write lines larger than PIPE_BUF, logger creates another file with postfix _big (for example lsd_dir/category_name/202302121626_big.log) and flock(LOCK_EX) for writing.

Install

npm install nodejs-lsd-logger

Usage

Import writeLog or writeJson function from the library and use it to write data. Both functions return Promise and you can catch logging errors.

// import { writeLog } from 'nodejs-lsd-logger';
import { writeJson } from 'nodejs-lsd-logger';

writeJson('path/to/lsd_dir', {
    string: 'string',
    number: 123,
}).catch((error) => {
    console.error(error);
});
