# Configure environment variables

Up until now, we've installed our tooling—but all of our configurations have been hardcoded. But, what if we have some configuration to use in our application? Let's update the `db.js` file in the repo to use environment variables set with Gitpod.

You can set environment variables inside a workspace using `gp env` (from the [Workspace CLI](/classic/user/configure/workspaces/gitpod-cli)). To see currently set environment variables, run `gp env`:

```bash theme={null}
gp env
```

Let's use `gp env` to set our environment variables:

```bash theme={null}
eval $(gp env -e USER=gitpod)
eval $(gp env -e DATABASE=eventhub_db)
```

And reference the variables in our `db.js` file by updating it to:

```javascript theme={null}
const { Pool } = require('pg');

const pool = new Pool({
	user: process.env.USER,
	host: 'localhost',
	database: process.env.DATABASE,
	password: '',
	port: 5432,
});

module.exports = pool;
```
