Is there a reason you are printing this. Debug comments like this can result in privacy concerns.
| UserService userService = UserServiceFactory.getUserService(); | ||
| String nickname = getUserNickname(userService.getCurrentUser().getUserId()); | ||
| System.out.println("nickname: " + nickname); | ||
| // commStream.add(nickname + ": ") //a way to make nicknames permanent |

Again remove commented code in all places.
| if (entity == null) { | ||
| return null; | ||
| } | ||
| String nickname = (String) entity.getProperty("nickname"); | ||
| return nickname; | ||
| } |

You could use a try and catch block here, instead of checking for entity null and catch on NullPointerException.
| out.println("<p>Set your nickname here:</p>"); | ||
| out.println("<form method=\"POST\" action=\"/nickname\">"); | ||
| out.println("<input name=\"nickname\" value=\"" + nickname + "\" />"); | ||
| out.println("<br/>"); | ||
| out.println("<button>Submit</button>"); | ||
| out.println("</form>"); |

you can just do
out.println("
Set your nickname here:
" +"<form method="POST" action="/nickname">" +
"<input name="nickname" value="" + nickname + "" />" +
"
"+
"Submit" +
"");

Better yet you can move the comment to a nickname_template.html file and just read it from there. This way you separate html from java. Here and other places.

Ok! I have put in the code in the first comment and will put it into another file in the next branch.

Can you comment why you want to redirect user to home here?

No particular reason other than that it was included in the week 3 user-nicknames example. Thank you for catching it! It will be deleted by the next commit

What if fetch fails can you add error case here and other places.

Done! I have made a function that throws an error if fetch fails and have implemented in every fetch call in this js file. It will appear in the next commit

I see this logic being used in multiple files, maybe pull it out to its own helper or util class, so you don't have to repeat code.

Ok! I have implemented the code in the first comment(will appear in the next commit) and will pull out the logic in the next branch I make. Thank you!
…ause the problems are addressed here; it is not a new venture or addition per se
