Hey, I'm trying to set up postgres, but I'm just accessing a public db so I don't want to set up tunneling.
Is it possible to do this? I tried following this (https://developers.cloudflare.com/workers/tutorials/query-postgres-from-workers-using-database-connectors/), but when I fetch my API and it tries to connect to postgres I receive:

(log) Fetch API cannot load: mainnet.db.explorer.indexer.near.dev

(log) Fetch API cannot load: mainnet.db.explorer.indexer.near.dev

(log) Fetch API cannot load: mainnet.db.explorer.indexer.near.dev

(log) Fetch API cannot load: mainnet.db.explorer.indexer.near.dev

my client connection looks like this:

      const client = new Client({
        user: 'public_readonly',
        password: 'nearprotocol',
        database: 'mainnet_explorer',
        hostname: 'mainnet.db.explorer.indexer.near.dev',
        port: '5432',
      })

      const client = new Client({
        user: 'public_readonly',
        password: 'nearprotocol',
        database: 'mainnet_explorer',
        hostname: 'mainnet.db.explorer.indexer.near.dev',
        port: '5432',
      })

      const client = new Client({
        user: 'public_readonly',
        password: 'nearprotocol',
        database: 'mainnet_explorer',
        hostname: 'mainnet.db.explorer.indexer.near.dev',
        port: '5432',
      })

The database connector connects to a WebSocket, which would be provided by the Tunnel. If you are connecting to a public DB that doesn't provide a WebSocket API, then it will not work.

Hello, I’m Allie!•4/12/23, 8:33 PM

No. At the moment, unless you have access to the TCP Worker beta, then you cannot connect to anything that doesn't support HTTP(S) or WebSockets, whether that be a Database, a Live Stream, or something else.

H

Hello, I’m Allie!•4/12/23, 8:34 PM

Note too that directly opening a connection to your DB in a Worker may not be the best approach anyway, as most databases are not optimized for extremely short-lived connections running only 1-2 queries.

JJorgeDev Does anyone know if it is possible to run workers on only one region?

C

Cyb3r-Jak3•4/12/23, 9:56 PM

Not without being enterprise. You can just make a firewall that blocks access to the worker apart from certain areas depending on your needs

Cloudflare Apps are pretty much abandoned/unmaintained at this point. Most of them are by third party devs as well, it might be that the ones you are using are broken
This channel is for workers, if you want to talk about Apps more, please use #general-discussions

guys are trying to use service binding. There are 2 worker
A "user" and a "parser".
I've written service binding in "parser "config. I run -local 2 worker . I try to get it via env.user, but I see there is no «user» in parser env, although at start it says that there is service binding in console

Hi, all , I saw event.cf.longitude is only available for Enterprise customers, so it means we 5$ paid plan users cannot access that? Thanks for your responding

Where did you see that it's Enterprise only?

Starting with workers and Lat/Long

Just started using Cloudflare and liking the testing that we are doing. We are working to get Latitude and Longitude into the header similar to how we are doing that with a competing CDN. I have been reading the articles below and having some issues just getting started with workers and the general setup. Any assistance would be appreciated.

李二牛li2niu•4/13/23, 4:43 AM

Keep in mind that the event.cf object and its properties, including event.cf.latitude, are only available to Cloudflare Enterprise customers in the scope of their workers running on the Cloudflare network.

By chance, does anyone have a sample Worker that has separate environments (staging/prod) with different endpoints and different environment variables for each?

I want to setup a staging API for my Worker that deploys to staging.example.com/api/v1 and uses separate environment variables (beta DB)

inside worker there is access to service binding, but not inside DO. How can this be solved? Workers work locally

The only concept that applies to Workers is accounts - so yeah, you could use other accounts but I wouldn't personally

I also don't use enough Workers for organisation to be an issue so take that with a grain of salt

When they receive a request, the Worker will be invoked in the colo that the user hit.

Hello, I’m Allie!•4/13/23, 10:04 AM

Workers only spawn when processing a Request, and then they are evicted, so that wouldn't really do much

(Also ideally we don't use JSON for the real binding)
