i tried to download release file and rename it to jssip.js
http://jssip.net/download/releases/jssip-3.1.4.js

add again
var jssip = require('./jssip.js');

and i got this:

How to fix? Thank you

Please, use the mailing list for usage questions. The above seems to be a problem within your JS+babel project, rather than being related to JsSIP itself.

[namnm]

@ibc Wrong! This is a problem from jssip. We should add the .babelrc file into npmignore

[ibc]

Sorry, what?

[namnm]

I think we should not publish the .babelrc file together in the npm package. We can have it in git repo and our local development env to transpile the code to es5 but we should not publish it to npm.

The code to be published to npm should have been transpiled already (lib-es5 dir) or untranspiled (lib dir). If user choose to use the tranpiled, they dont need to do anything. If they choose to use the untranpiled, they want to use there own config instead, so if we put .babelrc in the package, it will mess up with user's config.

Hope you understand

I've been reading about this and indeed it seems that including .babelrc in NPM modules overrides the user provided Babel settings within his app root folder. Is this, right?

[namnm]

Yes..

[ibc]

ok, jssip NPM 3.3.5 is out without .babelrc.
