   This is one of my trials:

   var Git = require("nodegit");
   
   exports.create = function (repoPath, name, options, callback) {                                                   
   
       if (typeof options === "function") {                                                                          
           callback = options;
           options = {};
       }       
   
       options = Object(options);                                                                                    
       options.sourceBranch = options.sourceBranch || "master";                                                      
   
       // open the repo
       openRepo(repoPath, function (repo) {                                                                          
           // get the source branch most recent commit                                                               
           repo.getBranchCommit(options.sourceBranch).then(function (commit) {                                       
               // create the branch                                                                                  
               Git.Branch.create(repo, name, commit, 0, Git.Signature.now("Gabriel Petrovay", "gabipetrovay@gmail.com", "")).then(function (branch) {
                   callback(null, branch);                                                                           
               }, ec(callback));
           }, ec(callback));
       }, ec(callback));                                                                                             
   };  
   
   function openRepo (path, callback, errCb) {
       var repoPath = require("path").resolve(path);
       return Git.Repository.open(repoPath).then(callback, errCb);                                                   
   }           
   
   function ec (callback) {
       return function(err) {
           callback(err);
       }
   }
   

   then I call:

   branch.create(".", "master_1", function (err) {
       if (err) {
           console.error(err);
       }
   });
   

   The answer is:

   [Error: Callback is required and must be a Function.]
   

   which is thrown from the Git.Branch.create line.

   The other trial is:

   exports.create_alt = function (repoPath, name, options, callback) {
   
       if (typeof options === "function") {
           callback = options;
           options = {};
       }
   
       options = Object(options);
       options.sourceBranch = options.sourceBranch || "master";
   
       // open the repo
       openRepo(repoPath, function (repo) {
           repo.checkoutBranch(name);
           callback(null);
       }, ec(callback));
   };
   

   and calling:

   branch.create_alt(".", "master_1", function (err) {
       if (err) {
           console.error(err);
       }
   });
   

   nothing happens. The repo remains on the master branch.

   I also did not find the equivalent of -b option in the checkout options

   it looks like logMessage argument (last arg) in the create is missing. Try adding that (empty string should be fine).
   Otherwise, we generally use the gitter channel for support questions. I'm going to close this issue in lieu of support there (unless this ends up being an actual bug, in which case I'll reopen it). I'll also add a line for a guide for this in our wanted guides/examples issue and reference this.
