you can add a commonJS module to a design document. It is available within
the whole design document and you can reference it from your show function.
here is an example:
{
"_id": "_design/somename",
"_rev": "275-a3f8495cc032a09fb1dfdbaa26da0703",
"views": {
"lib": {
"multi2": "function(x) { return x * 2; }",
"multi4": "function(x) { return x * 4; }"
}
}
}
}
You would then require the module in your show function with
require('lib/multi2') or require('lib/multi4').
You could also namespace this in the code above with
"lib": {
"modulenamesapce": {
"multi2": "function(x) { return x * 2; }",
"multi4": "function(x) { return x * 4; }"
}
}
}
and require it respectively.
