Use config file

[bhavin137]

I'm trying to pass mosca options as a from a config file. Reading the code, I understand that the config file has to be a node module This is what my config file looks like:

bhavin@home:/opt/mosca$ cat config.js
module.exports = {
    "port": 1883,
    "credentials": "/opt/mosca/credentials.json",
    "verbose": true,
    "logger": { "stream": require('fs').createWriteStream('/opt/mosca/info.log') }
}

but running mosca throws an error like so:

bhavin@home:/opt/mosca$ mosca -c /opt/mosca/config.js

Am I missing something here?

P.S: I have ownership of the /opt/mosca folder, so it's not a permissions issue

I was able to get it working by removing the credentials option. It seems "credentials" here refers to ssl credentials (and not auth credentials as I mistakenly assumed)

I think the only way to pass auth credentials file location is through the CLI at the moment @mcollina Is that true? And would it make sense to add a authCredentials option to the config file?

If so, I'd be happy to submit a PR

[mcollina]

Yes, send a PR!

If that's the case, need to update the wiki too which specifically references credentials: https://github.com/mcollina/mosca/wiki/Authentication-&-Authorization
