0.1.0 • Public • Published


A RESTful database request server. It listens for seven types of REST requests and responds with JSON API formatted resources.


npm install -g quarry


Currently, Quarry is built exclusively for PostgreSQL databases. Support for other database options will be added in the future, prior to the 1.0 release.

For now, you'll need PostgreSQL installed and started before running Quarry.

Quarry Config

Create a JSON config file for Quarry (default quarry.json) with the following "global" options:

  • connection : A hash containing the connection options for the database server:
    • host : The host address to connect directly to the database server
    • port : The port number the database server is listening on
    • user : The name of the user/role to connect to the database with
    • password : The password for the user/role
  • databaseScripts : An array of JavaScript file names used for specific database configurations (see below)
  • host : The host address to bind the Quarry connection to
  • port : The port number to listen for requests on

Database Scripts

Each database will need its own JavaScript file in order to outline its tables, fixtures, and permissions. This "database script" file will simply export an object with the following allowed nested parameters:

  • name : Optional database name parameter; if this is not supplied, then the file name of the database script is assumed to be the name of the database (i.e., "databases/example.js" would create a database "example")
  • tables : A hash of table definitions, where the key is the table name, and the value is an object with the following parameters:
    • columns : A hash of column definitions, where the key is the column name, and the value is a string representing the data type
    • fixtures : An array of hashes containing keys and values for the columns
    • allow : A hash of values or functions, where the key is the RESTful "action" name, and the value is either a boolean value, or a function that accepts the request data and returns a boolean value (when true, the request action is allowed). When an action is not mentioned in this hash, it is not allowed (equivalent to false value).

For convenience, and certainly not for security, you can simply set allow to true, in order to allow all the actions to be permitted on the table. This is definitely not recommended for stable or production projects, but is intended as an easy way to get up and running quickly.

RESTful Actions

The RESTful "actions" are a friendly way to refer to REST requests, and each represents a combination of an HTTP method and a URI format:

  • create (POST /resources) Create a new entry in the collection
  • delete (DELETE /resources/:id) Delete the addressed resource
  • deleteAll (DELETE /resources) Delete the entire collection
  • find (GET /resources/:id) Retrieve a representation of the resource
  • findAll (GET /resources) Retrieve all the collection's resources
  • replaceAll (PUT /resources) Replace the entire collection
  • update (PUT /resources/:id) Replace the addressed resource (or create if null)

Quarry Command

  • serve : Start the Quarry server in the current directory, with options:
    • -c, --config [file] : Use a specified config file, instead of the default "quarry.json"


Quarry config, "quarry.json"

  "connection": {
    "host": "localhost",
    "port": 5432,
    "user": "quarry_user",
    "password": null
  "databaseScripts": [
  "host": "db.example.com",
  "port": 54321

Database Script, "databases/example.js"

module.exports = {
  tables: {
    colors: {
      columns: {
        id      : 'serial',
        name    : 'text',
        hexCode : 'text'
      fixtures: [
        { name: 'Red',   hexCode: 'FF0000' },
        { name: 'Green', hexCode: '00FF00' },
        { name: 'Blue',  hexCode: '0000FF' }
      allow: {
        findAll: true,
        update: function ( request ) {
          return !!request.params.userId;

The above two configurations would result in two valid endpoints:
