javascript - I am trying to connect to connect to my SQL server database with node and hapi.js -

i trying test out connection sql server using node , hapi.js , run simple query on 1 of tables. new node , hapi trying figure out

so first folder structure follows have folder called api has routes in , doing routes get_aosdata.js works tested passing 'hello world' have query folder under api setting db connections in connection.js

this route looks

'use strict'; const query = require('../query/connection');  module.exports = {     method: 'get',     path: '/api/query/{id}',     config: {         pre: [             { method: query.getsqlconnection, assign: 'db' }         ],         handler: (request, reply) => {                 const request = new db.request();                 request.query(`select a.ordnbr, a.sotypeid, a.user6, a.lupd_datetime, a.user3, a.crtd_user, a.s4future01, a.slsperid, a.totmerch, a.custordnbr soheader                               join customer b                               on a.custid = b.custid                               join soline c                               on a.ordnbr = c.ordnbr                               sotypeid = 'q'`, ((err, recordset) => {                                  if (err) {                                     console.log(err);                                 }                                 reply(recordset);                               }));          }     } } 

i calling prereq connection code looks

const sql = require('mssql');  const dbconfig = {     server: 'myserver',     database: 'mydatabase',     user: 'myuser',     password: 'mypassword' }  const getsqlconnection = (request, reply) => {     sql.connect(dbconfig, ((err) => {                 if (err) {                     console.log(err);                 }     }));             return reply(); }  module.exports = getsqlconnection; 

this server

'use strict';  const hapi = require('hapi');  const server = new hapi.server();  server.connection({ port: 3001, host: 'localhost' });  server.route(require('./api/routes/get_aosdata'));  server.start((err) => {     if(err) {         throw err;     }      console.log(`server running at: ${server.info.uri}`); }); 

now error says pre @ position 0 not match of allowed types... clueless on error , cannot find fix anywhere. using hapi , mssql make call appreciated new @ node , hapi, have read lot on hapi , use it

this how doing hope helps

'use strict'; const sql = require('mssql'); const async = require('asyncawait/async'); const await = require('asyncawait/await'); const boom = require('boom');  const dbconfig = {     server: 'myserver',     database: 'mydb',     user: 'myuser',     password: 'mypass' }  const conn = new sql.connectionpool(dbconfig);  module.exports = {     method: 'get',     path: '/api/query/{id}',     config: {         handler: (request, reply) => {               conn.connect().then(() => {               req.query(``select a.ordnbr, a.sotypeid, a.user6, a.lupd_datetime, a.user3, a.crtd_user, a.s4future01, a.slsperid, a.totmerch, a.custordnbr soheader                           join customer b                           on a.custid = b.custid                           join soline c                           on a.ordnbr = c.ordnbr                           sotypeid = 'q'`).then((data) => {                   reply(data);                   conn.close();                 })               .catch((err) => {                reply(boom.badrequest(err.message, err));                 conn.close();               });           })           .catch((err) => {               reply(boom.badrequest(err.message, err));           });         }     } } 

in case in routes think

then server same

'use strict'; const hapi = require('hapi'); const boom = require('boom');  const server = new hapi.server();  server.connection({ port: 3001, host: 'localhost', routes: {cors: true} });  server.route(require('./api/routes/get_aosdata'));  server.start((err) => {     if(err) {         boom.badrequest(err.message, err);     }      console.log(`server running at: ${server.info.uri}`); }); 

this totally wrong way how got mine work
