How to pass data from VUEX Store to serverMiddleware API? - vuejs2

Question

Is it possible to pass data from Vuex Store to serverMiddleware in Nuxt.js?
async SET_DATA({commit}, payload) {
await this.$axios.$post('/api', { data: payload.data})
commit('SET_DATA', payload.data)
}
In nuxt.config
serverMiddleware: [
{ path: '/api', handler: '~/api/index' }
]
Then how do I access the data in api/index.js ?
export default function (req, res, next) {
// Get data from Store here
next()
}

Answer 1

Solution to my problem was found with bodyParser. Using app.use(bodyParser.json()).

Answer 2

The only way I found is;
readFile & writeFile functions.
In nuxt.config
modules: ['~/api/api.js'],
In api/api.js
I use this method, because of servermiddleware causes bug when you try to build app.
module.exports = function (moduleOptions) {
//Add middleware only with `nuxt dev` or `nuxt start`
var fs = require('fs');
// Save file from env or vuex anything comes with this
fs.writeFile('envTransfer.txt', JSON.stringify(this.options.env), function (err) {
if (err) throw err;
console.log('Saved!');
});
// Then call addServermiddleware
//Add middleware only with `nuxt dev` or `nuxt start`
if (this.options.dev || this.options._start) {
this.addServerMiddleware('~/api/index.js')
}
}
In the part api/index.js ( node & express )
const fs = require('fs');
const express = require('express');
const app = express()
....
let content="";
fs.readFile('envTransfer.txt', function(err, data) {
if (err) throw err;
content = data;
var obj = JSON.parse(content);
// do it what ever you want
app.get('/', (req, res, next) => {
// res.send('API root')
})
// export the server middleware
module.exports = {
path: '/api',
handler: app
}
});
