can you connect to the database with something like dbgate?

cucaracha•7mo ago

ive tried connecting from local host with the redis url and it works fine

Brody•7mo ago

okay thats good have you updated the environment variables you use?

cucaracha•7mo ago

yes. i went into my ws server environment variables and added the redis url as a reference variable ${{Redis.REDIS_URL}}

Brody•7mo ago

show me the client code that connects to redis please

cucaracha•7mo ago

import { createClient } from "redis";

const redisUrl = process.env.REDIS_URL;

const redisCon = {
  url: redisUrl,
};

import { createClient } from "redis";

const redisUrl = process.env.REDIS_URL;

const redisCon = {
  url: redisUrl,
};

if i run the ws server locally with this exact code with the REDIS_URL set to the one found in railway redis variables, it works fine

Brody•7mo ago

and can i see your service variables?

cucaracha•7mo ago

cucaracha•7mo ago

Brody•7mo ago
