Issue:
(NOTE: index.ts implements a GraphQL server using the Prisma Yoga server)
There are several strange aspects in this issue:

1. There are several loggers defined (imagechest.graphql, firebirdsql.queries, thumbnails.dbqueries ...) but only one (from the main file index.ts) produces output
2. Even for index.ts, nor the logging nor the console itself displays the very first logging lines (even with virtual console disabled) [see the first "console.log(...)" instruction below]
3. Logging actually only starts upon the first GraphQL query to index.ts - see log output below, whereas there are a number of logger.debug statements in the code before this point
4. Logging anomalies started after the functionality of the server got extended and source code became distributed among several source files. Until then, logging seemed quite normal.

Maybe not a bug but still strange and I have already investigated quite a lot: I find no obvious explanation to this behavior.

Despite to attempts to install log4js2 (the npm site and the project site give 2 slightly different instructions - see below), I cannot get my (otherwise running) application to compile with log4js2.

This is a pity, as the package looks really nice.

First attempt: npm install --save log4js2
Second attempt: npm i -S @log4js2/core

Configuration:
node -v: v10.10.0
npm -v: 6.5.0
tsc -v: Version 3.2.2
OS: ubuntu 18.04LTS

Error message:

If configuring by string, appenders will not work correctly

Can you please provide configuration example for this scenario?

Hi,
i have implemented a custom appender in order to log using sessionStorage of my browser, but after injecting my appender to the logger, nothing happens.

This is a piece of code:

import logger from './helpers/loghelper.js';
const log = logger.getLogger();
log.info('INIT');
.........
logger.addAppender("SESSION");
logger.setLogLevel("ALL");
log.info('DEBUG ON');

I don't know what i did wrong
Thanks
