loopback-connector-sqlite

LoopBack is a highly-extensible, open-source Node.js framework that enables you to create dynamic end-to-end REST APIs with little or no coding. It also enables you to access data from major relational databases, MongoDB, SOAP and REST APIs.

loopback-connector-sqlite is the SQLite3 connector module for loopback-datasource-juggler.

Checkout wiki pages to get updated information about this connector and how to use it with a LoopBack Application to create an API.

Basic usage

Installation

Install the module using the command below in your projects root directory:

npm i loopback-connector-sqlite

You will require loopback-datasource-juggler and node-sqlite3 modules for using this connector. The SQLite3 database can be configured to operate in 2 ways: with a DB file name or with an anonymous in-memory DB. This connector needs 2 configuration parameters:

• file_name(string): A file name for SQLite DB file. It can have any string value for file based SQLite usage or null for in-memory usage.
• debug(boolean): Used for disabling and enabling logging.

A DataSource with basic settings can be defined as shown below:

var DataSource = require('loopback-datasource-juggler').DataSource;
var dataSource = new DataSource(require('../index'), {
  file_name: 'dev.sqlite3',
  debug: false
});

Checkout examples folder to get the idea of basic usage. Run the examples from the root directory as follows:

node examples/[example_file]

SQLite3 configuration for tests

The .loopbackrc file holds the settings for the tests. It's in JSON format and has following content:

• For file based SQLite testing

{
  "sqlite": {
    "test": {
      "file_name": "test.sqlite3",
      "debug": false
    }
  }
}

• For anonymous in-memory SQLite testing

{
  "sqlite": {
    "test": {
      "file_name": null,
      "debug": false
    }
  }
}

The file_name is the name of the sqlite3 DB file, which will be created, or, used if already present. The debug value is to set debugging mode.

Running the tests

• execute npm install for installing all the dependencies.
• execute npm test to run all the tests.
