node-postgres supports TLS/SSL connections to your PostgreSQL server as long as the server is configured to support it. When instantiating a pool or a client you can provide an `ssl` property on the config object and it will be passed to the constructor for the [node TLSSocket](https://nodejs.org/api/tls.html#tls_class_tls_tlssocket).
|
|
|
|
## Self-signed cert
|
|
|
|
Here's an example of a configuration you can use to connect a client or a pool to a PostgreSQL server.
|
|
|
|
```js
|
|
const config = {
|
|
database: 'database-name',
|
|
host: 'host-or-ip',
|
|
// this object will be passed to the TLSSocket constructor
|
|
ssl: {
|
|
rejectUnauthorized: false,
|
|
ca: fs.readFileSync('/path/to/server-certificates/root.crt').toString(),
|
|
key: fs.readFileSync('/path/to/client-key/postgresql.key').toString(),
|
|
cert: fs.readFileSync('/path/to/client-certificates/postgresql.crt').toString(),
|
|
},
|
|
}
|
|
|
|
import pg from 'pg'
|
|
const { Client, Pool } = pg
|
|
|
|
const client = new Client(config)
|
|
await client.connect()
|
|
console.log('connected')
|
|
await client.end()
|
|
|
|
const pool = new Pool(config)
|
|
const pooledClient = await pool.connect()
|
|
console.log('connected')
|
|
pooledClient.release()
|
|
await pool.end()
|
|
```
|
|
|
|
## Usage with `connectionString`
|
|
|
|
If you plan to use a combination of a database connection string from the environment and SSL settings in the config object directly, then you must avoid including any of `sslcert`, `sslkey`, `sslrootcert`, or `sslmode` in the connection string. If any of these options are used then the `ssl` object is replaced and any additional options provided there will be lost.
|
|
|
|
```js
|
|
const config = {
|
|
connectionString: 'postgres://user:password@host:port/db?sslmode=require',
|
|
// Beware! The ssl object is overwritten when parsing the connectionString
|
|
ssl: {
|
|
rejectUnauthorized: false,
|
|
ca: fs.readFileSync('/path/to/server-certificates/root.crt').toString(),
|
|
},
|
|
}
|
|
```
