Can log4js-node run in a karma-browserify set up?

Question

I am trying to learn Node test-driven frameworks.

I figured I should include a logging system, but can't seem to get it to work.

yourself@BDD0:~/BDD/simplest$ npm run test-browser

> [email protected] test-browser /home/yourself/BDD/simplest
> ./node_modules/karma/bin/karma start

I'm hoping someone recognizes the error and can tell me what it means.

The Chrome browser has a console. I have nodejs-console in my dependencies.

Am I trying something that log4js cannot do?

Thanx.

Answer 1

Ok I got it to work.

I found it necessary to clone the log4js project and edit log4js.js, in order to add a single line :

 require('./appenders/console');

I have posted a Pull Request for my solution : Force bundling of appenders/console

I have created a little demo that shows it in action : javascript-bdd-baby-steps

Possibly my pull request will be rejected with a description of the correct solution. If so I will update here.

I hope this helps someone somewhere someday.
