To set up your MongoDB connection, go to index.js and edit the uri variable to your mongodb connection uri:

// process.env.mongodb << indicates the key to be used to identify process
const uri = process.env.mongodb || 'mongodb://localhost:27017/crud-app'
mongoose.connect(uri, {
    useNewUrlParser: true,
    useFindAndModify: false
},(err)=>{
    if(err){
        console.log('unable to connect to db')
        process.exit(1)
    }else{
        console.log('successfully connected to db')
    }
})

Or set up a local env variable as follows:

export mongodb=<MONGODB_CONNECTION_URI>
