## Usage
|
|
|
|
```js
|
|
var parse = require('pg-connection-string').parse;
|
|
|
|
var config = parse('postgres://someuser:somepassword@somehost:381/somedatabase')
|
|
```
|
|
|
|
The resulting config contains a subset of the following properties:
|
|
|
|
* `host` - Postgres server hostname or, for UNIX doamain sockets, the socket filename
|
|
* `port` - port on which to connect
|
|
* `user` - User with which to authenticate to the server
|
|
* `password` - Corresponding password
|
|
* `database` - Database name within the server
|
|
* `client_encoding` - string encoding the client will use
|
|
* `ssl`, either a boolean or an object with properties
|
|
* `cert`
|
|
* `key`
|
|
* `ca`
|
|
* any other query parameters (for example, `application_name`) are preserved intact.
|
|
|
|
## Connection Strings
|
|
|
|
The short summary of acceptable URLs is:
|
|
|
|
* `socket:<path>?<query>` - UNIX domain socket
|
|
* `postgres://<user>:<password>@<host>:<port>/<database>?<query>` - TCP connection
|
|
|
|
But see below for more details.
|
|
|
|
### UNIX Domain Sockets
|
|
|
|
When user and password are not given, the socket path follows `socket:`, as in `socket:/var/run/pgsql`.
|
|
This form can be shortened to just a path: `/var/run/pgsql`.
|
|
|
|
When user and password are given, they are included in the typical URL positions, with an empty `host`, as in `socket://user:pass@/var/run/pgsql`.
|
|
|
|
Query parameters follow a `?` character, including the following special query parameters:
|
|
|
|
* `db=<database>` - sets the database name (urlencoded)
|
|
* `encoding=<encoding>` - sets the `client_encoding` property
|
|
|
|
### TCP Connections
|
|
|
|
TCP connections to the Postgres server are indicated with `pg:` or `postgres:` schemes (in fact, any scheme but `socket:` is accepted).
|
|
If username and password are included, they should be urlencoded.
|
|
The database name, however, should *not* be urlencoded.
|
|
|
|
Query parameters follow a `?` character, including the following special query parameters:
|
|
* `host=<host>` - sets `host` property, overriding the URL's host
|
|
* `encoding=<encoding>` - sets the `client_encoding` property
|
|
* `ssl=1`, `ssl=true`, `ssl=0`, `ssl=false` - sets `ssl` to true or false, accordingly
|
|
* `sslcert=<filename>` - reads data from the given file and includes the result as `ssl.cert`
|
|
* `sslkey=<filename>` - reads data from the given file and includes the result as `ssl.key`
|
|
* `sslrootcert=<filename>` - reads data from the given file and includes the result as `ssl.ca`
|
|
|
|
A bare relative URL, such as `salesdata`, will indicate a database name while leaving other properties empty.
