Musare

MusareNode

Based off of the original Musare, which utilized Meteor.

MusareNode now uses NodeJS, Express, SocketIO and VueJS - among other technologies. We have also implemented the ability to host Musare in Docker Containers.

The master branch is available at musare.com You can also find the staging branch at musare.dev

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 can also serve 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 utilize 1 backend, 1 MongoDB server and 1 Redis server running for production, though it is relatively easy to expand.

Requirements

Installing with Docker: (not recommended for Windows users)

• Docker

Standard Installation:

• NodeJS _ nodemon: yarn global add nodemon _ node-gyp: yarn global add node-gyp
• Yarn (Windows) Yarn (Unix) (npm can also be used)

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

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

|Property|Description| |--|--| |serverDomain|Should be the url where the backend will be accessible from, usually http://localhost:8080 for non-Docker.| |frontendDomain|Should be the url where the frontend will be accessible from, usually http://localhost for docker or http://localhost:80 for non-Docker.| |frontendPort|Should be the port where the frontend will be accessible from, should always be port 81 for Docker, and is recommended to be port 80 for non-Docker.| |recaptcha.key|Can be obtained by setting up a ReCaptcha Site (v3).| |cookie.domain|Should be the ip or address you use to access the site, without protocols (http/https), so for example localhost.| |cookie.secure|Should be true for SSL connections, and false for normal http connections.| |siteSettings.logo|Path to the logo image, by default it is /assets/wordmark.png.| |siteSettings.siteName|Should be the name of the site.| |siteSettings.socialLinks|github, twitter and facebook are set to the official Musare accounts by default, but can be changed.|

1. Simply cp .env.example .env to setup your environment variables.

2. To setup snyk (which is what we use for our precommit git-hooks), you will need to:

   • Setup an account
   • Go to settings
   • Copy the API token and set it as your SNYK_TOKEN environment variable.

We use snyk to test our dependencies / dev-dependencies for vulnerabilities.

Installing with Docker

Configuration

To configure docker configure the .env file to match your settings in backend/config/default.json.
The configurable ports will be how you access the services on your machine, or what ports you will need to specify in your nginx files when using proxy_pass. COMPOSE_PROJECT_NAME should be a unique name for this installation, especially if you have multiple instances of Musare on the same machine. FRONTEND_MODE should be either dev or prod (self-explanatory).

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

docker-compose build

1. Set up the MongoDB database

   1. Set the password for the admin/root user.

   In .env set the environment variable of MONGO_ROOT_PASSWORD.

   1. Set the password for the musare user (the one the backend will use).

   In .env set the environment variable of MONGO_USER_USERNAME and MONGO_USER_PASSWORD.

   1. Start the database (in detached mode), which will generate the correct MongoDB users.

   docker-compose up -d mongo

2. Start redis and the mongo client in the background, as we usually don't need to monitor these for errors

docker-compose up -d mongoclient redis

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

docker-compose up backend frontend

1. 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

If you are using linting extensions in IDEs/want to run yarn lint, you need to install the following locally (outside of Docker):

   yarn global add eslint
   yarn add eslint-config-airbnb-base

Standard Installation

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.

1. 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

2. 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.

3. 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. Run yarn run bootstrap to install dependencies and dev-dependencies for both the frontend and backend.

2. Either execute yarn run dev:frontend and yarn run dev:backend separately, or in parallel with yarn dev.

Calling Toasts

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

import Toast from "vue-roaster";
new Toast({ content: "", persistant: true });

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"}})

Adding a package

We use lerna to add an additional package to either the frontend or the backend.

For example, this is how we would to add the webpack-bundle-analyser package as a dev-dependency to the frontend:

npx lerna add webpack-bundle-analyser --scope=musare-frontend --dev
