Musare

MusareNode

This is a rewrite of the original Musare in NodeJS, Express, SocketIO and VueJS. Everything is ran in it's own docker container, but you can also run it without Docker.

The site is available at https://musare.com.

Our Stack

• NodeJS
• MongoDB
• Redis
• Nginx (not required)
• VueJS

Frontend

The frontend is a vue-cli generated, vue-loader single page app, that's served over Nginx or express. The Nginx server not only serves the frontend, but also serves as a load balancer for requests going to the backend.

Backend

The backend is a scalable NodeJS / Redis / MongoDB app. Each backend server handles a group of SocketIO connections. User sessions are stored in a central Redis server. All data is stored in a central MongoDB server. The Redis and MongoDB servers are replicated to several secondary nodes, which can become the primary node if the current primary node goes down.

We currently only have 1 backend, 1 MongoDB server and 1 Redis server running for production, though it is relatively easy to expand.

Requirements

Option 1: (not recommended for Windows users)

• Docker

Option 2:

• NodeJS _ nodemon: yarn global add nodemon _ node-gyp: yarn global add node-gyp
• MongoDB Currently version 4.0
• Redis (Windows) Redis (Unix)

Getting Started

Once you've installed the required tools:

1. git clone https://github.com/Musare/MusareNode.git

2. cd MusareNode

3. cp backend/config/template.json backend/config/default.json

Values: The mode should be either "development" or "production". No more explanation needed. The secret key can be whatever. It's used by express's session module. The domain should be the url where the site will be accessible from, usually http://localhost for non-Docker. The serverDomain should be the url where the backend will be accessible from, usually http://localhost:8080 for non-Docker. The serverPort should be the port where the backend will listen on, usually 8080 for non-Docker. isDocker if you are using Docker or not. The apis.youtube.key value can be obtained by setting up a YouTube API Key. You need to use the YouTube Data API v3, and create an API key. The apis.recaptcha.secret value can be obtained by setting up a ReCaptcha Site. The apis.github values can be obtained by setting up a GitHub OAuth Application. You need to fill in some values to create the OAuth application. The homepage is the homepage of frontend. The authorization callback url is the backend url with /auth/github/authorize/callback added at the end. For example http://localhost:8080/auth/github/authorize/callback. Discord is currently unsupported The apis.discord.token is the token for the Discord bot. The apis.discord.loggingServer is the Discord logging server id. The apis.discord.loggingChannel is the Discord logging channel id. The apis.mailgun values can be obtained by setting up a Mailgun account. The redis.url url should be left alone for Docker, and changed to redis://localhost:6379/0 for non-Docker. The redis.password should be the Redis password you either put in your startRedis.cmd file for Windows, or .env for docker. The mongo.url needs to have the proper password for the MongoDB musare user, and for non-Docker you need to replace @musare:27017 with @localhost:27017. The cookie.domain value should be the ip or address you use to access the site, without protocols (http/https), so for example localhost. The cookie.secure value should be true for SSL connections, and false for normal http connections.

1. cp frontend/build/config/template.json frontend/build/config/default.json

Values:
The serverDomain should be the url where the backend will be accessible from, usually http://localhost:8080 for non-Docker. The recaptcha.key value can be obtained by setting up a ReCaptcha Site. The cookie.domain value should be the ip or address you use to access the site, without protocols (http/https), so for example localhost. The cookie.secure value should be true for SSL connections, and false for normal http connections.

Now you have different paths here.

Docker

Configuration

To configure docker simply cp .env.template .env and configure the .env file to match your settings in backend/config/default.json

1. Build the backend and frontend Docker images (from the main folder)

docker-compose build

1. Set up the MongoDB database

   1. Disable auth

   In docker-compose.yml remove --auth from the line command: "--auth" for mongo.

   1. Start the database

   docker-compose up mongo

   1. Connect to Mongo

   docker-compose exec mongo mongo admin

   1. Create an admin user

   db.createUser({user: 'admin', pwd: 'PASSWORD_HERE', roles: [{role: 'root', db: 'admin'}]})

   1. Connect to the Musare database

   use musare

   1. Create the musare user

   db.createUser({user: 'musare', pwd: 'OTHER_PASSWORD_HERE', roles: [{role: 'readWrite', db: 'musare'}]})

   1. Exit

   exit

   1. Add back authentication

   In docker-compose.yml add back --auth on the line command: "" for mongo.

3) Start the databases and tools in the background, as we usually don't need to monitor these for errors

docker-compose up -d mongo mongoclient redis

4) Start the backend and frontend in the foreground, so we can watch for errors during development

docker-compose up backend frontend

5) You should now be able to begin development! The backend is auto reloaded when you make changes and the frontend is auto compiled and live reloaded by webpack when you make changes. You should be able to access Musare in your local browser at http://<docker-machine-ip>:8080/ where <docker-machine-ip> can be found below:

• Docker for Windows / Mac: This is just localhost

• Docker ToolBox: The output of docker-machine ip default

Non-docker

Steps 1-4 are things you only have to do once. The steps to start servers follow.

1. In the main folder, create a folder called .database

2. Create a file called startMongo.cmd in the main folder with the contents:

   "C:\Program Files\MongoDB\Server\3.2\bin\mongod.exe" --dbpath "D:\Programming\HTML\MusareNode\.database"
   

   Make sure to adjust your paths accordingly.

3. Set up the MongoDB database

   1. Start the database by executing the script startMongo.cmd you just made

   2. Connect to Mongo from a command prompt

   mongo admin

   1. Create an admin user

   db.createUser({user: 'admin', pwd: 'PASSWORD_HERE', roles: [{role: 'userAdminAnyDatabase', db: 'admin'}]})

   1. Connect to the Musare database

   use musare

   1. Create the musare user

   db.createUser({user: 'musare', pwd: 'OTHER_PASSWORD_HERE', roles: [{role: 'readWrite', db: 'musare'}]})

   1. Exit

   exit

   1. Add the authentication

   In startMongo.cmd add --auth at the end of the first line

4. In the folder where you installed Redis, edit the redis.windows.conf file. In there, look for the property notify-keyspace-events. Make sure that property is uncommented and has the value Ex. It should look like notify-keyspace-events Ex when done.

5. Create a file called startRedis.cmd in the main folder with the contents:

   "D:\Redis\redis-server.exe" "D:\Redis\redis.windows.conf" "--requirepass" "PASSWORD"
   

   And again, make sure that the paths lead to the proper config and executable. Replace PASSWORD with your Redis password.

Non-docker start servers

Automatic

1. If you are on Windows you can run windows-start.cmd or just double click the windows-start.cmd file and all servers will automatically start up.

Manual

1. Run startRedis.cmd and startMongo.cmd to start Redis and Mongo.

2. In a command prompt with the pwd of frontend, run yarn run dev

3. In a command prompt with the pwd of backend, run nodemon

Extra

Below is a list of helpful tips / solutions we've collected while developing MusareNode.

Mounting a non-standard directory in Docker Toolbox on Windows

Docker Toolbox usually only gives VirtualBox access to C:/Users of your local machine. So if your code is located elsewere on your machine, you'll need to tell Docker Toolbox how to find it. You can use variations of the following commands to give Docker Toolbox access to those files.

1. First lets ensure the machine isn't running

docker-machine stop default

1. Next we'll want to tell the machine about the folder we want to share.

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" sharedfolder add default --name "d/Projects/MusareNode" --hostpath "D:\Projects\MusareNode" --automount

1. Now start the machine back up and ssh into it

docker-machine start default && docker-machine ssh default

1. Tell boot2docker to mount our volume at startup, by appending to its startup script

   sudo tee -a /mnt/sda1/var/lib/boot2docker/profile >/dev/null <<EOF

   mkdir -p /d/Projects/MusareNode
   mount -t vboxsf -o uid=1000,gid=50 d/Projects/MusareNode /d/Projects/MusareNode
   EOF

1. Restart the docker machine so that it uses the new shared folder

docker-machine restart default

1. You now should be good to go!

Fixing the "couldn't connect to docker daemon" error

Some people have had issues while trying to execute the docker-compose command. To fix this, you will have to run docker-machine env default. This command will print various variables. At the bottom, it will say something similar to @FOR /f "tokens=*" %i IN ('docker-machine env default') DO @%i. Run this command in your shell. You will have to do this command for every shell you want to run docker-compose in (every session).

Running Musare locally without using Docker

1. Install Redis and MongoDB

2. Install nodemon globally

yarn global add nodemon

1. Install webpack globally

yarn global add webpack

1. Install node-gyp globally (first check out https://github.com/nodejs/node-gyp#installation)

yarn global add node-gyp.

1. In both frontend and backend folders, do yarn install.

2. nodemon backend/index.js

Calling Toasts

You can call Toasts using our custom package, vue-roaster, using the following code:

import { Toast } from "vue-roaster";
Toast.methods.addToast("", 0);

Set user role

When setting up you will need to grant yourself the admin role, using the following commands:

docker-compose exec mongo mongo admin

use musare
db.auth("MUSAREDBUSER","MUSAREDBPASSWORD")
db.users.update({username: "USERNAME"}, {$set: {role: "admin"}})
