Let environment variables override configuration set by config.json
and/or app.set()
Behavior changes
- datasources.json now support dynamic configuration through
env-vars and config.json
- component-config.json will first consider env-var
for resolving dynamic conf, then fallback to config.json
- middleware.json will first consider env-var for resolving
dynamic conf, then fallback to config.json
- for all the dynamic confg, unresolved conf will return as `undefined`
Example:
Consider the following server/datasources.json
```
{
"mysql" : {
"name" : "mysql_db",
"host" : "${MYSQL_DB_HOST}",
...
}
}
```
Now you can provide the parameter through
an environment variable:
```
$ MYSQL_DB_HOST=127.0.0.1 node .
```
or you can set the value in server/config.json
```
{
"MYSQL_DB_HOST": "127.0.0.1"
}
```

LoopBack Boot
A convention-based bootstrapper for LoopBack applications.
For full documentation, see the official StrongLoop documentation: Defining boot scripts and Creating a LoopBack application.
Overview
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.
For more information, see Defining boot scripts.
Version notes
The version range 1.x is backwards compatible with app.boot provided
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.
This document describes the configuration conventions of the 2.x versions.
Installation
npm install loopback-boot
Usage
var loopback = require('loopback');
var boot = require('loopback-boot');
var app = loopback();
boot(app, __dirname);
app.use(loopback.rest());
app.listen();
