## Overview
2014-05-23 13:51:20 +00:00
2018-10-16 11:15:49 +00:00
A convention-based bootstrapper for LoopBack applications.
For full documentation, see the official StrongLoop documentation: [Defining boot scripts ](https://loopback.io/doc/en/lb2/Defining-boot-scripts ) and [Creating a LoopBack application ](https://loopback.io/doc/en/lb2/Creating-an-application ).

The loopback-boot module initializes (bootstraps) a LoopBack application. Specifically, it:
- Configures data-sources.
- Defines custom models
- Configures models and attaches models to data-sources.
- Configures application settings
- Runs additional boot scripts, so you can put custom setup code in multiple small files instead of in the main application file.

by LoopBack 1.x versions and the project layout scaffolded by `slc lb project`
up to slc version 2.5.
The version range `2.x` supports the new project layout as scaffolded by
`yo loopback` .
