NODEJS - connection to database ECONNREFUSED when using documents.write() - node.js

Question

I'm currently studying nodejs and marklogic, I'm running a sample code but I cannot make it work I'm getting econnrefused whenever I run the code.,
Here is my code,
my-connection.js
module.exports = {
connInfo: {
host: 'localhost',
port: 8008,
user: 'user',
password: 'password'
}
};
sample.js
const marklogic = require('marklogic');
const my = require('./my-connection.js');
const db = marklogic.createDatabaseClient(my.connInfo);
const documents = [
{ uri: '/gs/aardvark.json',
content: {
name: 'aardvark',
kind: 'mammal',
desc: 'The aardvark is a medium-sized burrowing, nocturnal mammal.'
}
},
{ uri: '/gs/bluebird.json',
content: {
name: 'bluebird',
kind: 'bird',
desc: 'The bluebird is a medium-sized, mostly insectivorous bird.'
}
},
{ uri: '/gs/cobra.json',
content: {
name: 'cobra',
kind: 'mammal',
desc: 'The cobra is a venomous, hooded snake of the family Elapidae.'
}
},
];
db.documents.write(documents).result(
function(response) {
console.log('Loaded the following documents:');
response.documents.forEach( function(document) {
console.log(' ' + document.uri);
});
},
function(error) {
console.log('error here');
console.log(JSON.stringify(error, null, 2));
}
);
I'm running it by typing node sample.js I'm using marklogic for the database, can someone help me identify the problem here,
I get ECONNREFUSED upon running the app, thank you!

Answer 1

ECONNREFUSED indicates no TCP listener process is running behind localhost:8008. That could mean MarkLogic is not running on your localhost, or it has no app-server configured at port 8008.
Check if http://localhost:8001 works on your machine, and brings up the MarkLogic Admin UI. If so, check the app-servers to see if you actually have one configured for 8008.
HTH!
