node.js - Conditionally updating / deleting a document in backend. Should I? Do I assign a PUT, POST, or DELETE http method? -


the below function "collection model".

given conditions, want either delete or update document.

should use put or delete?

i separate them , check validation / conditions on client, seems less dry.

i'll have add additional lines of code both client , server achieve same thing. 

collectionschema.statics.kill = function(o, cb) {       return collection         .findasync(o)         .then(function(existing) {           if (existing.length && (existing[0].vote !== 0 || existing[0].favorite == true)) {             return collection               .findbyidandupdate(o, {                 collected: !existing[0].collected               }, {                 new: true               })               .then(function(updated) {                 console.log('updated ', updated)                 return updated;               }).catch(function(err) {                 return err;               })           } else if (existing.length && existing[0].vote == 0 && existing[0].favorite == false) {             return collection               .removeasync({                 _id: existing[0]._id               })               .then(function(deleted) {                 return {                   message: 'deleted collection'                 }               }).catch(function(err) {                 return err;               })           }         }).catch(function(err) {           return err;         })     };

i think best option use simple rest model (a put update document , delete remove document).

then, client, call either update or remove method depending on conditions, say. improve concept, can send negative response client concerning delete event if document can't removed.
