QUESTION
I'm getting the following deprecation warning when running unit tests in a brand new Angular 12 application:
(node:14940) [log4js-node-DEP0004] DeprecationWarning: Pattern %d{DATE} is deprecated due to the confusion it causes when used. Please use %d{DATETIME} instead.
why log4js
prompts "karma" depends on it
. The warning itself is clear as to what should be done but there are two key missing pieces of information:
- it doesn't say when/if the old syntax will stop working
- it doesn't provide a workaround (other than forking
karma
and replacing the deprecated syntax with the new one - which I'm definitely not going to do).
Downgrading log4js
to an earlier version, which doesn't output the warning, using forceResolutions
doesn't seem like a good idea, especially since I've found a few github threads related to vulnerabilities in it, although karma doesn't seem to be affected.
The question: are there actionable paths for not getting the warning, or is "and now we wait" (for a karma
update) the only option?
Note: I've also asked it on karma's repo.

Answered 2022-Feb-16 at 17:00Got the fix from karma
maintainers:
Update karma
(in package.json > devDependencies.karma
) to ^6.3.12
.
Warnings gone. Well done, karma
. That was fast!
QUESTION
Log4js uses dynamic require for loading appenders. Webpack doesn't know at build time which appender will be used at runtime.
How can I use not build in appenders? like @log4js-node/logstashudp
...ANSWER
Answered 2022-Jan-16 at 08:55Let's say you want to add a new appender (that's not build in like tcp,file) like @log4js-node/logstashudp or any other appender.
So instead of:
