Example Apps for nforce-tooling Plugin

Yesterday I released the nforce-tooling plugin for nforce so today I thought I would follow up with some sample demos and a video walking through the process of using the plugin.

The video walks through two demos. The first is for standard functions like describe, querying tooling objects and creating/deleting records. The second demo show how to deploy a new Apex class to your org. You can find the code for these demos in the examples directory for the plugin.

To give you something to look at, here is the deploy.js code.

var nforce = require('nforce'),
  tooling = require('nforce-tooling')(nforce),
  Q = require("q");

var sfuser = process.env.SFUSER;
var sfpass = process.env.SFPASS;

// for the example, create a new class use the id here
var apexClassId = 'YOUR-APEX-CLASS-ID';
// the new code to update the class above with
var newApexCode = "public class ToolingDemo {\n String s = 's';\n}";
// we need this so we can clean up after ourselves
var metadataContainerId;

var org = nforce.createConnection({
  clientId: process.env.CLIENTID,
  clientSecret: process.env.CLIENTSECRET,
  redirectUri: 'http://localhost:3000/oauth/_callback',
  mode: 'single',
  plugins: ['tooling']
});

org.authenticate({ username: sfuser, password: sfpass}, function(err, resp){
  if(!err) {
    console.log('*** Starting Apex class deployment process... Hold tight. This is gonna be awesome. ***')
    createContainer('ExampleDeployContainer')
      .then(addUpdatedCode)
      .then(deploy)      
      .then(getDeployStatus)
      .fail(function(err) {
        console.log("== failure: " + err);
      });
  } else {
    console.log('Error connecting to Salesforce: ' + err.message);
  }
}); 

function createContainer(name) {
  var deferred = Q.defer();
  org.tooling.createContainer({name: name}, function(err, container) {
    // return the id of the newly created container
    if (!err) deferred.resolve(container.id);    
    if (err) deferred.reject(err);
  });         
  return deferred.promise;
}

function addUpdatedCode(containerId) {
  var deferred = Q.defer();

  // create the artifact that references the saved class and new code
  var artifact = org.tooling.createDeployArtifact('ApexClassMember', 
    {body: newApexCode, contentEntityId: apexClassId});

  org.tooling.addContainerArtifact({id: containerId, artifact: artifact}, function(err, resp) {
    // return the id of the container again
    if (!err) deferred.resolve(containerId)    
    if (err) deferred.reject(err);
  });         
  return deferred.promise;
}

function deploy(containerId) {
  var deferred = Q.defer();
  // so we can clean up
  metadataContainerId = containerId;
  org.tooling.deployContainer({id: containerId, isCheckOnly: false}, function(err, asnycContainer) {
    console.log('Deploying code...');
    // return the async container's id so we can check it's status
    if (!err) deferred.resolve(asnycContainer.id);
    if (err) deferred.reject(err);
  });
  return deferred.promise;
}

function getDeployStatus(asnycContainerId) {
  org.tooling.getContainerDeployStatus({id: asnycContainerId}, function(err, resp) {

    console.log('Checking status of the deployment...');
    if (resp.State === "Queued") {
      console.log("Status is currently queued. Checking deploy state again.");
      getDeployStatus(asnycContainerId);
    } else {
      if (resp.State === "Completed") {
        console.log("W00t! Code successfully deployed");
      } else if (resp.State === "Failed") {
        console.log("Deployment failed with: ");
        console.log(resp.CompilerErrors);
      } else if (resp.State === "Error") {
        console.log("Deployment failed with error: ");
        console.log(resp.ErrorMsg);
      } else {
        console.log("Deploy finished with a status of: " + resp.State);            
        console.log(resp);            
      }

      // delete the metadata container
      org.tooling.delete({type: 'MetadataContainer', id: metadataContainerId}, function(err, resp) {
        if (err) {
          console.log("Error deleting deployment container: " + metadataContainerId);
          console.log(err);
        }
      });           

    }
  });        
}
