I am currently learning Javascript/HTML/CSS in order to build some data dashboard. I have found this tutorialhttps://d3-dashboard.cube.dev/setting-up-a-database-and-cube-js
Currently I am getting stuck at this part:
The next step is to create a Cube.js data schema.
When opening the Cube.js playground at: http://localhost:4000, I get the following output in my terminal:
🦅 Dev environment available at http://localhost:4000, I get the following error:
🚀 Cube.js server (0.21.1) is listening on 4000
Error: getaddrinfo ENOTFOUND <YOUR_DB_HOST_HERE>
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:66:26)
And in the Cube.js playground webpage view:
Error while loading DB schema
Error: getaddrinfo ENOTFOUND <YOUR_DB_HOST_HERE> at
GetAddrInfoReqWrap.onlookup [as oncomplete](dns.js66:26)
I have edited the following file:
d3-dashboard/node_modules/@cubejs-backend/server-core/core/index.js
, with:
const checkEnvForPlaceholders = () => {
const placeholderSubstr = '<YOUR_DB_';
const credentials = [
'CUBEJS_API_SECRET=SECRET',
'CUBEJS_DB_TYPE=postgres',
'CUBEJS_DB_NAME=ecom',
'CUBEJS_WEB_SOCKETS=true'
/*'CUBEJS_DB_HOST',*/
/*'CUBEJS_DB_NAME',*/
/*'CUBEJS_DB_USER',*/
/*'CUBEJS_DB_PASS'*/
];
Any input on what I am doing wrong here? I am totally new to apps and front-ends, so it might be something "stupid" that I am sking, but I really would like to learn from my mistakes :)
Thank you for your time and potential inputs/help!
Have a great day :)
You definitely should not edit any files in the node_modules
directory. You should store the env
variables in the .env
file.
-your-cubejs-server-root
--schema
--.env
--//..
And it may look like
CUBEJS_DB_HOST=localhost
CUBEJS_DB_NAME=cubejs
CUBEJS_DB_USER=root
CUBEJS_DB_PASS=
CUBEJS_DB_TYPE=mysql
CUBEJS_API_SECRET=secret
The error you're getting is saying that the connection to the DB cannot be established. Because you're missing the proper CUBEJS_DB_HOST=
variable.
The minimum required set of variables differs for each database and can be found here https://cube.dev/docs/connecting-to-the-database
