How to add customFields in salesforce object using jsforce module..? using the metadata

Question

// creating metadata

var metadata = {

  fullName: 'SampleObject__c', 

  label: 'Sample Object',

  label: 'Sample Object',

  pluralLabel: 'Sample Object',

  nameField: {

    type: 'Text',

    label: 'Sample Object'

  },

  deploymentStatus: 'Deployed',

  sharingModel: 'ReadWrite'

};

conn.metadata.create('CustomObject', metadata, function(err, results) {

  if (err) { 

    console.err(err); 

  }

  else{

    console.log('success ? : ' + result.success);

    console.log('fullName : ' + result.fullName);

  }

});

I'm not able to create a customField here. The only Object is getting created and there is no documentation available to create a custom field using jsforce. I have tried one approach, i.e, after successful creation of the custom object, I have updated the metadata with custom fields, but failed. What is the approach to create customFields in the customObject.

In order to solve this issue, add an array of fields to your custom object metadata definition. I had a hard time with this too. I figured it out by creating the fields in Salesforce setup->create->objects (point and click admin) and then reading the metadata produced via:

conn.metadata.read(type, [fullName1, fullName2, ..], callback)     

Put the array of objects below into the metadata variable and it should work.

fields: [ { fullName: 'A_Value__c',

           externalId: 'false',

                label: 'A Value 2',

           precision: '18',

            required: 'false',

               scale: '0',

       trackTrending: 'false',

                type: 'Number',

              unique: 'false' },

         {  fullName: 'A3_Value__c',

          externalId: 'false',

               label: 'A Value 3',

           precision: '18',

            required: 'false',

               scale: '0',

       trackTrending: 'false',

                type: 'Number',

              unique: 'false' } ],
