Nodegit: How to modify a file and push the changes?

Question

Looked around for an example, but couldn\'t find one. The documentation is not explained and I could not figure it out.

How to modify a file (README.md for example),

Answer 1

Rafael's solution works for sure although I might add that there is no needed to perform a .connect into the server. Here is a minimal approach on pushing a repo:

• Pushing to master using only username and password authentication:

          //Previous calls
  
          }).then(function() {
              return repo.getRemote("origin"); //Get origin remote
          }).then(function(remote) {
              return remote.push(["refs/heads/master:refs/heads/master"], {
                  callbacks: {
                      credentials: function(url, userName) {
                          console.log("Requesting creds");
  
                          return NodeGit.Cred.userpassPlaintextNew("[USERNAME]", "[PASSWORD]");
                      }
                  }
              });
          }).then(function(err) {
              console.log("Push error number:");
              console.log(err);
          }).catch(function(err) {
              console.log(err);
          }).done(function(commitId) {
              console.log("All done");
          })
  

• Pushing to myBranch over SSH auth:

          //Previous calls
  
          }).then(function() {
              return repo.getRemote("origin"); //Get origin remote
          }).then(function(remote) {
              return remote.push(["refs/heads/myBranch:refs/heads/myBranch"], {
                  callbacks: {
                      credentials: function(url, userName) {
                          console.log("Requesting creds");
                          return NodeGit.Cred.sshKeyFromAgent(userName);
                      }
                  }
              });
          }).then(function(err) {
              console.log("Push error number:");
              console.log(err);
          }).catch(function(err) {
              console.log(err);
          }).done(function(commitId) {
              console.log("All done");
          })
