javascript - Use CouchDB with Node.js library -

couchdb uses javascript validate, query, map-reduce , on. i'd know there way use node.js library in these javascript functions? such use require('http') or third party modules installed npm.

thanks.

you can use node.js libraries long don't require node.js-specific libraries http. example, async works in couchdb. rule of thumb: if it's intended server and client, should good.

you can use commonjs's module.exports , exports[something] patterns share code between views. check out the documentation more details.

for example, consider view:

{   _id:"_design/test",   views: {     lib: {       test: "exports.guests = 42;"     },     fish_per_person: {       map: function(doc){         var guests = require('views/lib/test').guests; // 42         emit(doc.number_of_fish, doc.number_of_fish / guests);       }     }   } } 

the fish_per_person view requires value guests exported in lib/test.
