[2458] how to require some libraries only for the server

In case you need to require some libraries only for the server, you can use the process.server variable set to true when webpack is creating the server.bundle.js file.

I don't know what exactly I should do.

For example I want to take data from Mongodb with mongoose into asyncData. How can i make mongoose server-only?

~/mongo/mongo-test.js

import mongoose from 'mongoose'

const user = new mongoose.Schema({
    // some definition
})

const userModel = mongoose.model('user',user)

export function findSomeone(){
    userModel.find({
        // find datas
    } ,callback)
}

~/router/index.vue

<template>
    <div></div>
</template>

<script>
import mongoTest from '~/mongo/mongo-test.js'

export default {
  asyncData: (context) => { if (context.isServer) { mongoTest.findSomeone() } },
}
</script>

<style>
</style>

Or should i use nuxt as a middleware?
