I have been checking for the connectivity of MariaDB, with Sequelize.
const Sequelize = require('sequelize');
// Setting up database (MariaDB) connection
const sequelize = new Sequelize('dbName', 'usr', 'pass', {
host: 'localhost',
dialect: 'mariadb'
});
But I am getting the following error:
/home/lt-196/api/node_modules/sequelize/lib/sequelize.js:236
throw new Error('The dialect ' + this.getDialect() + ' is not supported. Supported dialects: mssql, mysql, postgres, and sqlite.');
^
Error: The dialect mariadb is not supported. Supported dialects: mssql, mysql, postgres, and sqlite.

MariaDB
For MariaDB compatibility you have to install the package mariasql#0.1.20, or higher.
The configuration needs to look like this:
var sequelize = new Sequelize('database', 'username', 'password', {
dialect: 'mariadb'
})
Or Try this:
MariaSQL: https://www.npmjs.com/package/mariasql
A node.js binding to MariaDB's non-blocking (MySQL-compatible) client library.
var Client = require('mariasql');
var c = new Client({
host: '127.0.0.1',
user: 'foo',
password: 'bar'
});
c.query('SHOW DATABASES', function(err, rows) {
if (err)
throw err;
console.dir(rows);
});
c.end();
MariaSQL is recommended.

The project runs without any errors when run from Visual Studio Code by runung the cmd : npm start.
But when runing the project as a windows service I´m getting an error about the PORT.
The PORT=8080 is initialized in the (Environment file) env. file.
Bellow is the env. file:
NODE_ENV=production
# hapi server config
PORT=8080
HOST=localhost
HOST_URL=http://localhost:8080
COOKIE_ENCRYPT_PWD=xxxxxxxxxx...
#sql server config

SQL_ENCRYPT=false
#okta config

OKTA_CLIENT_SECRET=xxxxxxxxxxx
Bellow is the config file:
"use strict";
const dotenv = require( "dotenv" );
const assert = require( "assert" );
dotenv.config();
const {

When installing a fresh version of xampp I'm able to connect my js script to MySQL through the terminal.
const mysql = require('mysql');
let con = mysql.createConnection({
host: "localhost",
user: "root",
password: "",
port:3307
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
PS C:\login> node connection.js
Connected!
I've been trying another db which I have credentials for but it seems to be a problem when you have a password property in the con object. That it will not connect with a password :P What Im I doing wrong here?

I'm trying to test GraphQL server with Jest and Knex. I had a hard time figuring out how to use knexfile in typescript. But now everything is working fine for development and production envs, except for testing.
Here's my current knexfile.ts:
// knexfile.ts
const defaults = {
client: 'pg',
connection: {
host: DB_HOST,
user: DB_USER,
password: DB_PASSWORD,
database: DB_DATABASE
},
pool: {
min: 2,
max: 10
},
migrations: {
extension: 'ts',
directory: './migration',
tableName: 'knex_migrations'
},
seeds: {
extension: 'ts',
directory: './seed'
}
};
interface KnexConfig {
[key: string]: object;
}
const knexConfig: KnexConfig = {
local: {
client: 'sqlite3',
connection: {
filename: './dev.sqlite3'
}
},
development: {
...defaults,
debug: true,
useNullAsDefault: true
},
production: {
...defaults
}
};
/**
* `export default` does not work, causes `client` missing problem
* at database migration.
*/
export = knexConfig;
This is global setup for Jest:
// globalSetup.ts
export = async () => {
try {
// Start http server
await httpServer.listen(PORT);
// Rollback and migrate
// await knex.migrate.rollback().then(() => knex.migrate.latest());
knex.migrate.latest();
} catch (err) {
// Log the error
logger.error('', err);
}
};
This is global teardown:
// globalTeardown.ts
export = async () => {
try {
await knex.migrate.rollback();
// Shutdown server
httpServer.close(() => logger.info('Server closed'));
} catch (err) {
// Log the error
logger.error('', err);
}
};
It keeps giving me error:

You need to add ts-jest, which will transpile your ts files for jest.
Install it
npm install --save-dev ts-jest
Add default ts-jest config
npx ts-jest config:init
we use something a bit like this in our knexfile.js
require('ts-node/register');
require('dotenv').config();
const {
SERVER_HOST,
SERVER_USER,
SERVER_PASSWORD,
SERVER_DATABASE,
SERVER_DATABASE_TEST,
} = process.env;
i'm trying to run my project on centos 7 OS, i'm trying to install my project by writing node install_server.js

Cant seem to figure it out, could i get a helphand?
Template Literals are not supported until version 4.8.4 according to
http://node.green/
which is a great resource.
I tried to use Knex.js on Node.js by following code:
var Promise = require("bluebird");
var knex = require("knex")({
client: 'pg',
user : 'username',
database : 'database',
password: "password",
migrations: {
tableName: 'knex_migrations'
},
pool: {
min: 0,
max: 7
}
});
knex.select("*").from("users").then(function(rows){
console.log(rows);
});
But, it threw an error about Runner object as follows:
/path/to/myapp/node_modules/knex/lib/interface.js:27
return new Runner(this).run().then(onFulfilled, onRejected);
^
TypeError: undefined is not a function

When I try to use stream, pipe, exec and transaction, same error occurred.
Please tell me how to solve this problem...
I was really careless about configuration of client.
I have mistaken in description of "connection". It have to be written as follows:
var Promise = require("bluebird");
var knex = require("knex")({
client: 'pg',
connection: {
host : '127.0.0.1',
user: 'username',
database: 'database',
password: 'password'
},
migrations:{
tableName:"knex_migrations"
},
pool: {
min: 0,
max: 7
}
});
knex.select("*").from("users").then(function(rows){
console.log(rows);
});
It works with no problems.
Thank you!
