 Lab 06: TCP Chat Server | ||
====== | ||
|
||
## To Submit this Assignment | ||
* Fork this repository | ||
* Write all of your code in a directory named `lab-` + `<your name>` **e.g.** `lab-brian` | ||
* Push to your repository | ||
* Submit a pull request to this repository | ||
* Submit a link to your PR in canvas | ||
* Write a question and observation on canvas | ||
|
||
## Include | ||
* `.gitignore` | ||
* `.eslint` | ||
* `package.json` | ||
* `gulpfile.js` | ||
* `README.md` | ||
* write a paragraph about your project | ||
* write documentation on how to get the project running | ||
* write documentation on how to connect to the server | ||
This app is a telnet chatroom that uses sockets vis server.js powered by node. | ||
|
||
-Many users allowed to chat. | ||
-Each user is assigned unique user name. | ||
-Local Server | ||
|
||
### Tech | ||
|
||
The TCP chat server uses a number of open source projects to work properly: | ||
|
||
* [node.js] - evented I/O for the backend | ||
* [Server.js] | ||
* [node modules] | ||
|
||
And of course TCP Chat Server itself is open source with a [public repository][TCP] | ||
on GitHub. | ||
|
||
### Installation | ||
|
||
TCP Chat Server requires [Node.js](https://nodejs.org/) v4+ to run. | ||
|
||
Install the dependencies and devDependencies and start the server. | ||
|
||
```sh | ||
$ node Install | ||
$ npm init -y | ||
$ npm i -S uuid | ||
``` | ||
## How to connect | ||
|
||
* Clone the Repo in terminal | ||
* Open you network Preferences and grab your IP address | ||
* In your terminal run the "node server.js" command and you will recieve a message saying that you are connected | ||
* Split pane from your Shell menu in terminal | ||
* In the new pane run this command telnet -your IP address- -port- then hit enter | ||
for ex. "telnet 10.0.0.178 3000" and you will see "Escape character is '^]'." and that means you are connected. | ||
|
||
## Description | ||
|
||
* Create a TCP Server using the NodeJS native `net` module | ||
* Create a Client Constructor | ||
* When sockets connect to the server, a new `Client` instance should be made | ||
* All clients should have a unique `id` property - this should come from the use of `node-uuid` | ||
* When sockets are connected with the client pool they should be given event listeners for `data`, `error`, and `close` events | ||
* When a socket emits the `close` event, the socket should be removed from the client pool | ||
* When a socket emits the `error` event, the error should be logged on the server | ||
* When a socket emits the `data` event, the data should be logged on the server and the commands below should be implemented | ||
|
||
## Custom commands | ||
* `@all` should trigger a broadcast event | ||
* `@nickname` should allow a user change their nickname | ||
* `@dm` should allow a user to send a message directly to another user by nick name or by their guest id _(unique client id)_ | ||
* when a user sends a message, their nickname should be printed | ||
* **i.e.** `cfcrew: sup chatterz` | ||
* When sockets connect to the server, a new `Client` instance is made. | ||
* All clients have a unique `id` property - this will come from the use of `node-uuid` | ||
* When sockets are connected with the client pool they will be given event listeners for `data`, `error`, and `close` events | ||
* When a socket emits the `close` event, the socket will be removed from the client pool | ||
* When a socket emits the `error` event, the error will be logged on the server | ||
* When a socket emits the `data` event, the data will be logged on the server and the commands below will be implemented | ||
|
||
### Chat Features | ||
|
||
* @all triggers a broadcast event | ||
* @nickname allows a user change their nickname | ||
* @dm allows a user to send a message directly to another user by nick name or by their guest id (unique client id) | ||
when a user sends a message, their nickname will be printed | ||
i.e. cupid: sup lover |

This line is causing your socket to close when a user enters a command that does not satisfy the condition of any of your if blocks. Instead you should continuing down to the default emitter on line 77. You should remove this line from here. You could put it in its own event. |
