Install

npm install servicenow-rest

GlideRecord

var GlideRecord = require('servicenow-rest').gliderecord;
 
var gr = new GlideRecord('instance','tablename','user','password','v1')

Version is optional

query

//methods options
gr.setReturnFields('number,short_description');
gr.addEncodedQuery('active=true');
gr.setLimit(10);
 
gr.query().then(function(result){ //returns promise
    console.log(result)
})

get

 
gr.get('sysid').then(function(result){
    //your code
}).catch(error) {
    //errors
})

insert

var obj = {
    short_description:"Production Server down",
    description:"latin words here",
    priority:1
};
gr.insert(obj).then(function(response){
    //your code
}).catch(error) {
    //errors
})

update

var obj = {
    comment:"hey whats up"
}
gr.update('sysid',obj).then(function(response){
    //your code
}).catch(error) {
    //errors
})

clone

//two parameters
//sysid of record you want to clone
//array fields that you want to clone
var arr1 = ['short_description','description']
gr.clone('sysid',arr1).then(function(value) {
    console.log(value);
})

addProxy

If proxy requires credentials they need to be embedded in the URL

gr.addProxy('https://user:[e-mail]');

delete

 
gr.get('sysid').then(function(response){
    //your code
}).catch(error) {
    //errors
})

GlideAggregate

var GlideAggregate = require('servicenow-rest').glideaggregate;

query

gr.addEncodedQuery('encodedquery')
gr.addAggregate('agg','fieldname') //agg options: MIN,MAX,SUM,AVG
gr.groupBy('fieldname')
gr.addHaving('sum','impact','>',1) // Aggregate,fieldname,operator,value
gr.addCount(int) //integer
gr.orderByDescending() // Automatically sorts by ascending
 
gr.query().then(function(value) {
    console.log(value);
})

ImportSet

Create records on import set tables that are immediately transformed

var ImportSet = require('servicenow-rest').importset;
 
var gr = new ImportSet('instance','tablename','user','password') //tablename should be the import table here

get

gr.get(sysid).then(function(value) { console.log(value); }

insert

gr.get(

Attachment

var Attachment = require('servicenow-rest').attachment;
 
var gr = new Attachment('instance','tablename','user','password')

get

gr.get(sysid).then(function(value) {
    console.log(value);
})

delete

gr.delete(sysid).then(function(value) {
    console.log(value);
})

getAttachment

gr.getAttachment(sysid).then(function(value) {
    console.log(value)
})

getAttachments

gr.getAttachments(tablename,sysid,dir)
    .then(function(value) {
        console.log(value); //value is an array of file names attached
    })

attachFile

gr.attachFile(tablename, sysid,file,dir).then(function(value) {
    console.log(value);
});

About Promises##

A promise is an alternative to callback hell. It's pretty simple

gr.query() //This right here returns a 'promise'
    .then(function(value) {
    //code when successful
    },function(error) {
        code when failed
    }) //resolve and reject are functions with one argument. When the request succeeds, the resolve function is called. When it fails, the reject function is called
 
//alternative
gr.query().then(function(value) {
 
}).catch(function(error) {
    /error code here
})
