File sharing system made in Node.js with MongoDB, supporting user register, edit and delete, file upload (by selected users) and download and search by multiple standards.

• Install Node.js, the normal version already comes with NPM

• Install MongoDB

• Install all dependencies from the package.json file in the current folder, in the Terminal type the following command (you need a package manager):

npm install

• Create a folder in your local drive called data and another one inside it called db:

C:\data\db

• Add Mongo’s bin folder to the Path Environment Variable (for Windows).

• Create the file db.js in the folder config with the following code:

if (process.env.NODE_ENV == "production") {
    //URL to your Cloud database
    module.exports = { mongoURI: "mongodb+srv://user:password@cluster_name.mongodb.net/database_name?retryWrites=true&w=majority" }
}
else {
    //Local URL to access via Browser (27017 is Mongo default connection PORT)
    module.exports = { mongoURI: "mongodb://user:password@localhost:27017/database_name" }
}

• Start MongoDB, in the Terminal type the following command:

mongod

• Create a new database and admin:

mongo

use nameofthedatabase
db.createUser(
  {
    user: "myDatabaseAdmin",
    pwd: "abc123",
    roles: [ { role: "dbOwner", db: "nameofthedatabase" } ]
  }
)

• Create the files drive_key.json and gmail_key.json in the folder config/google containing the data for authentication with Google APIs, or set it with a .env file like the following:

# GMail OAuth2 API information
OAUTH_CLIENT_ID_GMAIL = CLIENT_ID
OAUTH_SECRET_GMAIL = SECRET
GMAIL_REFRESH_TOKEN = TOKEN
# Service account
OAUTH_SERVICE_ID_GMAIL = SERVICE_ID
OAUTH_SERVICE_PRIVATE_KEY_GMAIL = -----BEGIN PRIVATE KEY-----\n KEY \n-----END PRIVATE KEY-----\n

# GDrive OAuth2 API information
OAUTH_CLIENT_ID_DRIVE = CLIENT_ID
OAUTH_SECRET_DRIVE = SECRET
DRIVE_REFRESH_TOKEN = TOKEN
# Service account
OAUTH_SERVICE_ID_GMAIL = SERVICE_ID
OAUTH_SERVICE_PRIVATE_KEY_GMAIL = -----BEGIN PRIVATE KEY-----\n KEY \n-----END PRIVATE KEY-----\n

• Start the application in another terminal window (nodemon will automatically restart your application every time you make a change in any .js file and save it, if you don't have the package, you can install it globally on your computer with npm install -g nodemon):

nodemon app.js

• Open localhost:8081 in your Browser and have fun!
