CodeU - Nemo

Welcome to Nemo, It's complete and functional, but leaves plenty of room for improvement.

Changes we've made since we started:

• Nemo uses filters to determine if a user has access to a specific page of the app. Logged in users no longer have access to login/register page and users that aren't logged in have access to only those two pages.
• Nemo has profile pages for users where they can update their About Me's and view their sent messages.
• Nemo has private and public conversations.
• Nemo allows you to add/remove users from a conversation.
• Nemo keeps your conversations safe by allowing only members access.
• Nemo allows you to create conversations with titles that have multiple words.
• Nemo allows you to upload profile pictures and see other users' pictures with their messages.
• Nemo features a notification page that allows you to see when messages and conversations are being made.
• Nemo has an Activity Feed that allows users to see when new users join, create conversations, send messages, and update their About Me's.
• Nemo has an dynamic search feature that allows users to search for other users.
• Nemo has a Bot Framework that allows developers to contribute their own Bots.
• Nemo has NemoBot, a bot that functions as an assistant.
• Nemo has ConversationStatBot, a bot that provides conversation statistics.

Step 1: Download Java

Check whether you already have Java installed by opening a console and typing:

javac -version

If this prints out a version number, then you already have Java and can skip to step 2. If the version number is less than javac_1.8, then you have an old version of Java and should probably upgrade by following these instructions.

Download the JDK (not the JRE) from here.

Retry the javac -version command in a new console window to check the installation. If you still don't see a version number, then update your PATH environment variable so it contains Java's bin directory. Follow these directions to do so.

Step 2: Download Maven

This project uses Maven to compile and run our code. Maven also manages dependencies, runs the dev server, and deploys to App Engine.

Download Maven from here. Unzip the folder wherever you want.

Make sure you have a JAVA_HOME environment variable that points to your Java installation, and then add Maven's bin directory to your PATH environment variable. Instructions for both can be found here.

Open a console window and execute mvn -v to confirm that Maven is correctly installed.

Step 3: Install Git

This project uses Git for source version control and GitHub to host our repository.

Download Git from here.

Make sure Git is on your PATH by executing this command:

git --version

If you don't see a version number, then make sure Git is on your PATH.

Step 4: Setup your repository

Follow the instructions in the first project to get your repository setup.

Step 5: Run a development server

In order to test changes locally, you'll want to run the server locally, on your own computer.

To do this, open a console to your codeu_project_2018 directory and execute this command:

mvn clean appengine:devserver

This tells Maven to clean (delete old compiled files) and then run a local App Engine server.

You should now be able to use a local version of the chat app by opening your browser to http://localhost:8080.

Step 6: Make a change!

• Bring down the existing server by pressing ctrl+c in the console running the App Engine devserver.
• Modify a .java or .jsp file. (Try updating the homepage by editing the index.jsp file.)
• Bring the devserver back up by executing mvn clean appengine:devserver again.
• Refresh your browser to see your changes!
